Kappy · Answer

XCode 4.4.1 is required for Mountain Lion. You have installed the wrong version. You need to uninstall it then download and install the proper version.You need to add some more RAM. 2 GBs is just not sufficient with Lion or Mountain Lion.

Welcome to Apple CommunitiesOpen Terminal and type:sudo /Developer/Library/uninstall-devtools --mode&#x3D;allXcode 4.4 is supported in 10.8. Go to App Store and install Xcode

yoneken · Answer

I have already installed Xcode 4.4 (and Command Line Tools).But, there is no uninstall-devtools in /Developer/Library/.How to install it?

yoneken · Answer

Okay. I found it in /Library/Developer/Shared/uninstall-devtools

yoneken · Answer

I got it!Thank you so much mende1 and other guys.What a great community here!!

mende1 · Answer

You&#x27;re welcome

Liang Qi · Answer

I am not that lucky like yoneken. My installation of Xcode 3.2.6 was crashed. Then reboot got same issue.Login with safe mode and found there is no "/Developer/Library/uninstall-devtools" on my hard disk. Could someone share it with me? Thanks.

Liang Qi · Answer

OK, I just installed ML again...

XiaoBaiTu · Answer

Solution taken from:http://www.kuhnline.com/wp/?p&#x3D;787Hold down the Shift key at startup and the system will boot into Safe ModeYou can try running the uninstall script as mentioned in many forums.sudo /Developer/Library/uninstall-devtools –mode&#x3D;allThis did not help at all in my case.Browse to /system/library/extensionsdelete all 3 extensions that begin with CHUDNewer versions of XCode do not install these extensions so they won’t be missed.Reboot and the system should boot normally.

rakesh_mac · Answer

Thanks a lot XiaoBaiTu, you saved my day.I found the those 3 extensions in /System/Library/Extensions and I deleted those files beginning with CHUD and it worked like a charm.🙂
