While moving HD icon I placed it on top of or near the xcode icon on desktop. now xcode won't run. All hardware tested fine at apple and we reinstalled operating system. also HD icon removed from desk. Activity monitor %150 from xcode. Xcode removed and reinstalled twice. Girl at Genius bar stumped too.
Mac Air OsX 10.8.2
MacBook Air, OS X Mountain Lion (10.8.2)
Older Xcode versions used com.apple.Xcode.plist.
Oops, I spoke too soon. I get this error message again?
“mx_sw_ch Project” is locked for editing and you may not be able to save your changes. Do you want to unlock it?
“mx_sw_ch Project” is currently locked because you are not the owner of the file and do not have write permission.
Thanks, but the OP is running Mountain Lion. He needs to be using the latest version of Xcode or for sure there's going to be problem trying to get it to run.
I wasn't suggesting that the OP run an older Xcode version.
What happens if you answer 'Yes' to the unlock message?
!.) Here's the 1st error message I get:
“mx_sw_ch Project” is locked for editing and you may not be able to save your changes. Do you want to unlock it?
“mx_sw_ch Project” is currently locked because you are not the owner of the file and do not have write permission.
2.) Here's the message after I press unlock: It repreats about every 5 seconds.
The file “UserInterfaceState.xcuserstate” could not be unlocked.
Could not add write permission to the file because you do not own it. Try modifying the permissions of the file in the Finder or Terminal.
I found that I can still run my programs between warnings.
Xcode version 4.5.2
Use finder and Ctl-Click on 'mx_sw_ch.xcodeproj' and use Get Info to display the Sharing and Permissions for the file (note, this file is actually a special package directory). Is this an Xcode project that you need?
If you want to use Terminal, enter this command:
ls -al FOLDER_THAT_HOLDS_YOUR_XCODE_PROJECTS/mx_sw_ch/mx_sw_ch.xcodeproj/project.xcworkspace/xcuserdata/YOUR_ID.xcuserdatad
You need to substitute something like '/Users/YOUR_ID/myProjects' for FOLDER_THAT_HOLDS_YOUR_XCODE_PROJECTS, and your Mac user ID for YOUR_ID.
The output of the command should show the UserInterfaceState.xcuserstate file and its ownership like this:
-rw-r--r-- 1 myID myID 13681 Dec 2 2011 UserInterfaceState.xcuserstate
-rw-r--r-- 1 myID myID 29637 Sep 7 2010 WorkspaceState.xcuserstateMessage was edited by: xnav
Tried the Ctl-Click on 'mx_sw_ch.xcodeproj' and changed access to all user read/write but still no luck.
BTW, this problem happens on all my projects not just mx_sw_ch.xcodeproj.
Sorry, not sure what to substitute in the terminal command. It's getting a little complicated to follow.
It's looking like I need to just switch users and dump this one. Class is starting in a few days and I need to
focus my attention on SQL. Never thought this problem would be so difficult.
What do you guys think?
Migrate to the user that works.
@xnav : perfect description of the problem, and your solution solved the issue on my side

I had this happen when I accidently told Xcode too open the directory that contains all my projects. If Xcode works from a new/different user ID then try deleting everything that starts:
~/Library/Preferences/com.apple.dt.* under the user experiencing the problem.
its 2016 now and you saved me! thanks man
You can only open it with launchpad. That is standard with apple.
xcode won't run.
