When someone says &quot;edit your .plist file&quot; or &quot;your .profile&quot; or &quot;.bash_profile&quot; etc, this just confuses me. I have no idea where these files are, how to create them if I have to do that, etc, and also why there seem to be so many different ones (why? Do they do different things?)

So could someone please explain very patiently to a previous Windows user (wanting desperately to become more familiar with the pleasant if initially somewhat confusing OS X world) how to do this step by step?

I need the variables to be set both for GUI applications and command line applications, and at the moment it&#39;s for an ant script that needs the variables, but there will most likely be other needs as well.

Please note that I have Lion too, since many of the answers you get Googling seem to be outdated for Lion...

Also note that I have practically zero experience using the Terminal. I&#39;m willing to learn, but please explain for a novice...

Most questions regarding this problem are due to missing Xcode; I have Xcode 4.2 installed.

    ERROR: The autodetected CC(/usr/bin/gcc-4.2) is LLVM based, it is not yet fully supported by ruby and gems, please read `rvm requirements`, and set CC=/path/to/gcc .

So I could probably just grab gcc elsewhere, but I&#39;m mostly concerned as to why this is happening. Shouldn&#39;t installing Xcode be enough?

Can&#39;t install Ruby under Lion with RVM – GCC issues

On my old Mac running Snow Leopard, I could type &quot;ios&quot; into spotlight and it would start up the iPhone/iPad emulator by itself.

I have since had to get a new machine running Lion. I have installed Xcode for Lion, I have installed the developer tool options from the preferences panel.

But the &quot;ios&quot; option is no longer there :(  The only way now seems to be to run Xcode, create an empty project and then launch emulator with the run option.

I have searched and searched the intertubes and the facewebs, but nothing helps.

Does anyone know how to run only the emulator on Lion?

UPDATE:
THIS IS RESPONSE TO @ike_love thread below.
THAT answer is not assured to work on all Yosemite machines.

How to run iPhone emulator WITHOUT starting Xcode?

I am using the z Shell (`zsh`) instead of the default bash, and something wrong happen so that all commands that used to work are no longer recognized:

    ls
    zsh: command not found: ls

    open -e .zshrc
    zsh: correct &#39;open&#39; to &#39;_open&#39; [nyae]? 


I don&#39;t know how to reset `zsh` or how to fix this. Here is the content of `$PATH` variable:

    echo $PATH
    /Users/Malloc/bin/Sencha/Cmd/3.1.2.342:/usr/local/bin/mate


I cannot open the `.bash_profile` file nor `.zshrc` file, seems the only solution is to reset the `zsh`. Any ideas? 


**EDIT:**

I even tried to reset `zsh` as indicated in [this thread][1], but always got `command not found` error:

    exec zsh
    zsh: command not found: zsh


So what&#39;s going on? Why all commands are lost?

-bash: make: command not found

Where did the &quot;make&quot; command go?



Where can I find &quot;make&quot; program for Mac OS X Lion?

I&#39;m trying to install Imagemagick on OSX Lion but something is not working as expected.

    -&gt; brew install imagemagick

    /usr/local/git/bin/git
    ==&gt; Cloning https://github.com/adamv/ImageMagick.git
    Cloning into /Users/klebershimabuku/Library/Caches/Homebrew/imagemagick--git...
    fatal: https://github.com/adamv/ImageMagick.git/info/refs not found: did you run git      update-server-info on the server?
    Error: Failure while executing: git clone --depth 1 https://github.com/adamv/ImageMagick.git /Users/kleber/Library/Caches/Homebrew/imagemagick--git

brew doctor says:


    -&gt; brew doctor
    We couldn&#39;t detect gcc 4.0.x. Some formulae require this compiler.

    Some &quot;config&quot; scripts were found in your path, but not in system or Homebrew folders.

    `./configure` scripts often look for *-config scripts to determine if software packagesare installed, and what additional flags to use when compiling and linking.

    Having additional scripts in your path can confuse software installed via Homebrew if the config script overrides a system or Homebrew provided script of the same name.

    /Users/kleber/.rvm/gems/ruby-1.9.2-p180@global/bin
    passenger-config

    Setting DYLD_LIBARY_PATH can break dynamic linking.
    You should probably unset it.


And yes, I have XCode 4.1 installed and running.

How do I install imagemagick with homebrew?

It works ok as a single tool:

    curl &quot;someURL&quot;
    curl -o - &quot;someURL&quot;

but it doesn&#39;t work in a pipeline:

    curl &quot;someURL&quot; | tr -d &#39;\n&#39;
    curl -o - &quot;someURL&quot; | tr -d &#39;\n&#39;

it returns:

    (23) Failed writing body

What is the problem with piping the cURL output? How to buffer the whole cURL output and then handle it?

Why does cURL return error &quot;(23) Failed writing body&quot;?

I installed mySQL on my Mac. Beside starting the SQL server with mySQL.prefPane tool installed in System Preferences, I want to know the instructions to start from command-line.
I do as follows:

After

I start the mySQL server by command-line, but it produces an error as below:

How to start MySQL server from command line on Mac OS Lion?

I recently upgraded to OSX 10.7, at which point my rails installation completely borked when trying to connect to the psql server.   When I do it from the command line using 

    psql -U postgres

it works totally fine, but when I try to run the rails server or console with the same username and password, I get this error 

    ...activerecord-3.0.9/lib/active_record/connection_adapters/postgresql_adapter.rb:950:in `initialize&#39;: could not connect to server: Permission denied (PGError)	
    Is the server running locally and accepting
    	connections on Unix domain socket &quot;/var/pgsql_socket/.s.PGSQL.5432&quot;?

Any ideas what might be going on would be super helpful!  Thanks!

Repairing Postgresql after upgrading to OSX 10.7 Lion

This question may look like a duplicate of: https://stackoverflow.com/questions/2715055/how-to-uninstall-postgresql-on-my-mac-running-snow-leopard however, there are two major differences. I&#39;m running Lion and I&#39;m trying to uninstall PostgreSQL 9.0.4. I&#39;ve looked at the last question and the link that it referenced, but I did not find a file called &quot;uninstall-postgresql&quot; when I run this command:

    sudo find / -name &quot;*uninstall-*&quot;  

So, I assume this means that the uninstall process for 9.0.4 is different than that of 8.x.

I&#39;ve seen a couple of posts in different places describing a method for manual uninstallation but, similarly, some of the directories/files referenced are not present on my machine.

Any assistance or direction you can provide would be greatly appreciated.

Just for reference, this is the link the other poster used to uninstall postgres from snow leopard. As I tried to step through these commands, most of them choked with some variant of &quot;command not found&quot;.

---

UPDATE:

In addition to `brew uninstall postgres`, should I remove any of the following files/directories manually? Keep in mind I want to completely wipe the slate clean, no data files/database tables or anything.


    &gt; sudo find / -name &quot;*postgres*&quot;             
    find: /dev/fd/3: Not a directory

Completely uninstall PostgreSQL 9.0.4 from Mac OSX Lion?

Whenever I open a new tab in Terminal using &lt;kbd&gt;Cmd&lt;/kbd&gt; + &lt;kbd&gt;T&lt;/kbd&gt;, it opens bash in the same directory, as the previous tab. This works fine when I&#39;m in the `~` directory, but if I&#39;m anywhere else, I get an error loading `.bashrc`

    Last login: Sat Oct 15 21:10:00 on ttys002
    -bash: .bashrc: No such file or directory
    Jakub-Arnolds-MacBook-Pro:projects darth$ 

It looks like `.bashrc` is loaded via relative and not absolute path, because if I do `source ~/.bashrc`, everything works smoothly.

![loaded bashrc][1]

I think this is a OS X Lion related problem, because before the upgrade from Snow Leopard, I didn&#39;t have the same issue. But that might be caused by Terminal always opening at `~`, I don&#39;t remember if it tried to open the same directory.

**However the question remains the same, how can I make Terminal load `~/.bashrc` via absolute path, and not relative?**

How to fix Terminal not loading ~/.bashrc on OS X Lion

I&#39;m attempting to [re-install Ruby 1.9.3 with a patch that will allow me to use ruby-debug][1].

When following the instructions and running

    rvm reinstall 1.9.3 --patch debug --force-autoconf

It runs through and after applying the patch spits out:

&gt; rvm requires autoreconf to install the selected ruby interpreter however autoreconf was not found in the PATH.

Unfortunately, googling around for how to install autoreconf on OS&amp;nbsp;X&amp;nbsp;v10.7 (Lion) (or much information about it at all) seems to be a dead end.

Since setting up my development environments on Mac OS X Lion (brand new macbook air purchased in January 2012), I have noticed that resolving to a virtual host is very slow (around 3 seconds) the first time but after that is fast as long as I continue loading it regularly.

If I leave it untouched for a couple of minutes and then reload again, the first reload is (again) painfully slow; seems like something is being cached. 

As can be seen below I am not using the .local TLD.

My setup: Apache 2 - MySQL - PHP installed and enabled - added a couple of virtual hosts one of which I created for localhost

My /etc/hosts:

    127.0.0.1       localhost
    255.255.255.255 broadcasthost
    ::1             localhost
    fe80::1%lo0     localhost
    127.0.0.1       myproject.dev
    ::1             myproject.dev
    fe80::1%lo0     myproject.dev


My virtual host set-up in username.conf: 

    NameVirtualHost *:80
    
    &lt;Directory &quot;/Users/myusername/Sites/&quot;&gt;
        Options Indexes MultiViews
        AllowOverride None
        Order allow,deny
        Allow from all
    &lt;/Directory&gt;
    
    &lt;VirtualHost *:80&gt;
        ServerName localhost
        DocumentRoot /Users/myusername/Dropbox/dev_envs/
    &lt;/VirtualHost&gt;
    &lt;VirtualHost *:80&gt;
        ServerName myproject.dev
        DocumentRoot /Users/myusername/Dropbox/dev_envs/myprojectname
    &lt;/VirtualHost&gt;



How can I eliminate slow resolving/loading of localhost/virtualhost (a 2-3 second lag) on Mac OS X Lion?

I am kind of new to mac as well as mongodb.

I have a weird doubt, accessing the database created using mongodb on mac?

I know, in windows there is a folder called c:\data\db, where my database files are stored.

How and where in mac, the database is stored.

I remember doing something like 

    sudo mkdir -p /data/db
    sudo chown `id -u` /data/db

to create such a folder on mac, but I didn&#39;t find any database file in this folder, though i created a database.

Where are the database files saved on mac?

Any help would be really appreciated.

What is the easiest way to activate PHP and MySQL on Mac OS 10.6 (Snow Leopard), 10.7 (Lion), 10.8 (Mountain Lion)?

I&#39;d prefer to use any bundled versions before resorting to downloading from the PHP or MySQL websites. That also rules out MAMP and similar.

I&#39;m comfortable at the command line in Terminal.

After upgrading to Mac OSX Lion I figured out that /etc/hosts is not looked up in first place for name resolution anymore. This leads to some side effects like:

 1. Entries in /etc/hosts are resolved painfully slow
 2. You can&#39;t not override existing domains, e.g. 127.0.0.1 www.google.com
 3. If you get search domain entries from DHCP, let say .lan, and some funny guy configured localhost.lan to something else then 127.0.0.1 in the local DNS you can not reach your localhost anymore.

Is this behavior intended? Does it make any sense? And most important, how can I come back to the old behavior.

[Ping][1] returns this by default:

    64 bytes from 203.173.50.132: icmp_seq=0 ttl=244 time=57.746 ms

Is there some way I can get it to add the timestamp?

For example,

    Mon 21 May 2012 15:15:37 EST | 64 bytes from 203.173.50.132: icmp_seq=0 ttl=244 time=57.746 ms

I have an application with a view-based `NSTableView` in it.  Inside this table view, I have rows that have cells that have content consisting of a multi-row `NSTextField` with word-wrap enabled.  Depending on the textual content of the `NSTextField`, the size of the rows needed to display the cell will vary. 
 
I know that I can implement the `NSTableViewDelegate` method -`tableView:heightOfRow:` to return the height, but the height will be determined based on the word wrapping used on the `NSTextField`.  The word wrapping of the `NSTextField` is similarly based on how wide the `NSTextField` is… which is determined by the width of the `NSTableView`.

Soooo… I guess my question is… what is a good design pattern for this?  It seems like everything I try winds up being a convoluted mess. Since the TableView requires knowledge of the height of the cells to lay them out... and the `NSTextField` needs knowledge of it&#39;s layout to determine the word wrap… and the cell needs knowledge of the word wrap to determine it&#39;s height… it&#39;s a circular mess… and it&#39;s driving me *insane*.

Suggestions?

If it matters, the end result will also have editable `NSTextFields` that will resize to adjust to the text within them.  I already have this working on the view level, but the tableview does not yet adjust the heights of the cells.  I figure once I get the height issue worked out, I&#39;ll use the -`noteHeightOfRowsWithIndexesChanged` method to inform the table view the height changed… but it&#39;s still then going to ask the delegate for the height… hence, my quandry.

Thanks in advance!

I get `Illegal Instruction: 4` errors with binaries compiled with GCC 4.7.2 under Mac OS X 10.8.2 (&quot;Mountain Lion&quot;), when those binaries are run under Mac OS X 10.7.x (&quot;Lion&quot;) and earlier versions. The binaries work properly under Mac OS X 10.8.x.

I added `-mmacosx-version-min=10.5` to my compile flags and this seems to help resolve the issue for 10.5.x, 10.6.x and 10.7.x clients, whatever that issue is. 

Which gets to my question(s):

 * What is the `Illegal Instruction: 4` error?
 * Why does `-mmacosx-version-min=10.x` fix this specific error on `10.x` and greater clients?

I&#39;d like to apply this fix to my makefiles, but would like to know what it is doing before I pull the trigger. (Will I have larger binaries? Do I still have 64-bit binaries? Are there gotchas with this approach I should know about? Unintended side-effects? Etc.)

Error when install pylibmc using pip

**[edit]** I was troubleshooting problems with my development environment when I noticed one of my problems was the dependency on ImageMagick, since it&#39;s a vital part of my app.

---

After upgrading to OS X Lion (10.7) i no longer had ImageMagick available, i then tried installing again using MacPorts without success, i then installed from source, and the install wasn&#39;t very successfully i had convert and identify but it output error messages that i unfortunately dont have anymore, i by some strange reason decided to remove all of my MacPort libraries and started using Homebrew, i tried installing ImageMagick, it installs OK but when i try to use it throws this error

    dyld: Library not loaded: /opt/local/lib/libltdl.7.dylib
      Referenced from: /usr/local/bin/convert
      Reason: Incompatible library version: convert requires version 11.0.0 or later, but libltdl.7.dylib provides version 10.0.0
    Trace/BPT trap: 5

I read online but i have no clue on whats going on here, i found that libltdl is called libtool, and that i obviously need to upgrade it to a newer version, but i havent found any indication of how or where to find the source, or if this should be already be handled by homebrew and why it hasn&#39;t.

I tried installing ImageMagick again from source using [this installer script https://github.com/masterkain/ImageMagick-sl](https://github.com/masterkain/ImageMagick-sl) but when i try to use convert it throws a similar error.

    $ convert gnome.jpg -resize 50% gnome_.jpg

ImageMagick and OS X Lion trouble

I recently uninstalled Xcode 4.2 and re-installed Xcode 4.3.1. Command Line Tools are installed. I then installed MacPort using “dmg” disk images for Lion from macports.org. Since, I was getting `sudo: port: command not found` after every use of port, I followed [this][1] and [this post][2] to create a `.bash_profile` file(wasn&#39;t present earlier) and then put in it the following but to no avail.

Python library `gevent`, version 0.13.6 (the current version on PyPI) will not `pip install` on OS X Lion, Python 2.7 (and probably others.) It works fine on Snow Leopard.

How can I install the Python library &#39;gevent&#39; on Mac OS X Lion

I am having trouble getting MacPorts to function properly. I just installed OSX Lion 10.7.3 I downloaded and installed MacPorts first, and then after reading the requirements, I downloaded Xcode4.3 from the App Store, and then installed it.  I launched Xcode and it looks to be operational and functional.  However when I attempted to port with MacPorts, it gave me this error message(excerpt):

    Warning: xcodebuild exists but failed to execute
    Warning: Xcode does not appear to be installed; most ports will likely fail to build.

I followed the advice from:

https://stackoverflow.com/questions/7442447/how-do-i-install-additional-packages-for-xcode-on-osx-lion-to-allow-macports-to

 and installed command_line_tools_for_xcode from the Preferences within Xcode. I closed Xcode, and again got the errors:

I am uncertain where to go next with this. How do i trouble shoot my Xcode and MacPort interface?  

Unable to get MacPort functionality after installing Xcode 4.3

I&#39;m getting a really annoying side effect happening in osx that I can&#39;t seem to find a way to fix: for some reason the full screen applications keep switching positions. For example, if I have Safari, Mail and Xcode open in full screen, in exactly that order, every once in a while they will swap positions (eg. Xcode will sometimes move to the left, so the that swiping left will bring me to Safari instead of mail). The order of these applications is important for productivity purposes, and it gets really confusing when you have 6 of them open and all of a sudden Mail goes from spot 6 to spot 2.

Any ideas how to get this switching of places to stop?

I installed PostgreSQL using Homebrew on Lion. It starts okay but wouldn&#39;t shutdown. I tried:

    $ #started with
    $ pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log start
    $ #tried stoping with
    $ pg_ctl -D /usr/local/var/postgres stop -m immediate
    waiting for server to shut down................................... failed
    pg_ctl: server does not shut down

---

I fixed this issue by deleting the Launch Agent:

    launchctl unload -w ~/Library/LaunchAgents/org.postgresql.postgres.plist
    rm ~/Library/LaunchAgents/org.postgresql.postgres.plist

I am getting this error on startup of Hadoop on OSX 10.7:

&gt; Unable to load realm info from SCDynamicStore

It doesn&#39;t appear to be causing any issues with the functionality of Hadoop.

I am trying to install Ruby 1.9.3 but am having problems. 
I installed RVM, then typed:

    rvm install 1.9.3

The output says:

The log says:

I just wanted to **diable the elastic scrolling/bounce effect** in Safari (OSX Lion).

I found the solution to set `overflow: hidden` for body in css, but as expected it only **disables the scrollbar**, so if the website is &quot;longer&quot; than the screen you *won&#39;t be able to scroll!*

Any solutions or hints are welcome!
Thanks!

I have recently updated to Lion and enabled Web Sharing in the System Preferences but I am unable to get php working.

I added an info file to the web root directory and it outputs the file as text.

    info.php
    with the content
    &lt;?php phpinfo(); ?&gt;



How do you get php working on Mac OS X?

I have found a few other posts that show how to add a script to increment the build number with a script:

https://stackoverflow.com/questions/9258344/xcode-better-way-of-incrementing-build-number

https://stackoverflow.com/questions/7371345/xcode-projects-build-number

https://stackoverflow.com/questions/4694070/can-xcode-insert-the-version-number-into-a-librarys-filename-when-building

But what I want to do, is only increase the build number when I use ARCHIVE (both before and after).

Example:
If current build number is 21, then when I choose Product &gt; Archive the build number will be increased to 22, it will go through its process of building and creating the Archive file with the build number of 22, and then when it is finished archiving, it will increase the build number to 23.


Xcode-Increment build number only during ARCHIVE?

Trying to do a make install of git from source, and it keep kicking up the error:
    
     make install
    * new build flags or prefix
    CC credential-store.o
    In file included from credential-store.c:1:
    In file included from ./cache.h:8:

                ^
    1 error generated.
    make: *** [credential-store.o] Error 1

No amount of Googling has turned up anything on lib.intl.h. What is this elusive library, and how can I get it so I can finally install git?

What is libintl.h and where can I get it?

I have a Cocoa app that has an `NSWindowController` controlling an `NSWindow` with an `NSComboBox` in it. Nothing special, and it worked fine until upgrading to OS X 10.7.2. Now I get the following exception, which occurs only once, when the window controller&#39;s window loads. (Since the window controller in my app remains loaded, it happens only once per app launch.) Subsequently focusing and unfocusing the combo box does not trigger it.

Anyone know whether something changed in 10.7.2, and if so how to work around it?

(This is happening with Xcode 4.2.)

I&#39;m tryng to use Sublime Text from the terminal, for example by typing `subl`.

I&#39;m following the steps from Sublime Text&#39;s website:

&gt; Setup
&gt;
&gt; The first task is to make a symlink to subl. Assuming you&#39;ve placed Sublime Text 2 in the Applications folder, and that you have a ~/bin directory in your path, you can run:
&gt;

    ln -s &quot;/Applications/Sublime Text 2.app/Contents/SharedSupport/bin/subl&quot; ~/bin/subl

I keep getting `permission denied : ~/bin/subl: Permission Denied`

I have been searching around for a similar problem but can&#39;t find one that&#39;s applicable. Can someone point me to the right direction?

When I run 

    screen

on the remote host(running Linux), I obtain the following error:

    Cannot find terminfo entry for &#39;xterm-256color&#39;.

I am running terminal on Mac OSX Lion to access the remote host. I have googled to find out the solution to this problem and it appears that people suggest doing

    export TERM=xterm-color

which doesn&#39;t work for me. 

Please help.

My project worked perfectly on simulator+device,  
but now, after upgrading to **lion** os and **xcode 4.1**, I get this error when gps is active!

    server did not accept client registration 68

It&#39;s a gps based application, and i&#39;m nervous to not debug app in simulator!

Any idea to solve this issue?

**UPDATE**: Gps on Simulator doesn&#39;t work also on Xcode 3.2.6 + LION.

    DROP DATABASE db_name;
    ERROR 1010 (HY000): Error dropping database (can&#39;t rmdir &#39;./db_name&#39;, errno: 66)
