You basically need to add an entry to your registry to stop process growth for tabs.

I’ve copied the steps required below

1) Open RegEdit
2) Browse to HKEY_LOCALMACHINE -> SOFTWARE -> Microsoft -> Internet Explorer -> Main
3) Add a dword under this key called TabProcGrowth
4) Set TabProcGrowth to 0

Recently needed to change the way svn dealt with pbxuser files, found the following article that shows you how to tell svn to ignore certain files, but before I could do anything I had to be able to see the “hidden” svn folder where this article came in handy!

I’ve copied the crucial snippets here so that I don’t lose them….

Show hidden files

From Terminal run the following command…

defaults write com.apple.Finder AppleShowAllFiles YES

Then you need to get Finder to relaunch, hold down the option key and click the Finder icon in the Dock, then select Relaunch

Now when you look at folders any hidden ones are visible, including the important .svn

SVN Ignore files

Step 1. Open the subversion configuration file
~/.subversion/config
NOTE: If the “.subversion” directory doesn’t exist yet then run this command which fails but will create the necessary files to get you started:
svn status

Step 2. Enable “global-ignores” and add new things to ignore
Find the line that contains the text “global-ignores” and append the following text:
build *~.nib *.so *.pbxuser *.mode* *.perspective*

Step 3. Enable “auto-properties”
Located and uncomment (e.g. remove the leading “#” character) the line that looks like this:
# enable-auto-props = yes

Step 4. Add additional properties
Then go to the end of the file, in the [auto-props] section, and append these lines:
*.mode* = svn:mime-type=text/X-xcode
*.pbxuser = svn:mime-type=text/X-xcode
*.perspective* = svn:mime-type=text/X-xcode
*.pbxproj = svn:mime-type=text/X-xcode

“3.3.1 Applications may only use Documented APIs in the manner prescribed by Apple and must not use or call any private APIs.”

The following non-public APIs are included in your application:
addTextFieldWithValue:label:
textFieldAtIndex:

Jeff LaMarche has a great article that shows an alternative, that doesn’t use any Private API’s and therefore shouldn’t get you rejected.

To correct perform the following…

1) Start up the program Terminal Utilities/Terminal
2) Enter the following where XXXXXXXXXXXXX is what you want to appear in place of __MyCompanyName__:
defaults write com.apple.Xcode PBXCustomTemplateMacroDefinitions ‘{”ORGANISATIONNAME” = “XXXXXXXXXXXXX”;}’
3) Press enter
4) Shut down and restart Xcode.
