This week I bought my first Mac in about 10 years (yeah!). It's a used Mac Pro (2x2GHz Dual-Core Xeon with 2GB RAM). It has a fresh install of Mac OS X Lion 10.7.2. I've only installed OmniOutlner Pro, Textmate, and Ruby RVM.
I've also downloaded and installed Xcode 4.2.1 from the App Store. At first, Xcode worked fine (only launched to see if it worked). Then, the next day I launched Xcode to start using it and it crashed immediately upon launch. Since then, I've tried many things to try to correct the problem: rebooting, reinstalling, redownloading and reinstalling, deleting and reinstalling, deleting iTunes and reinstalling (an early Stack Overflow answer suggested this), and more. Nothing seems to help. Sometimes I can get as far as clicking on a menu item in XCode (while the crash message is being displayed), but that's it.
Everything else seems to work perfect on this machine, so I doubt it's the hardware. I do not have the OS X install DVD.
I bought this system so I can program in Xcode. What would you do if you were me?
UPDTE-1: Here are the first lines from the Problem Details and System Configuration report (in general it seems most of these I have looked at for this problem seem to be talking about the IDE Navigator Log):

UPDATE-2: Bummer. I tried the approach referenced by Michael Dautermann below, but it didn't work. Here's what I typed in Terminal:
sudo tmutil disablelocal
sudo /Developer/Library/uninstall-devtools --mode=all
sudo /Developer-old/Library/uninstall-devtools --mode=all
sudo /Developer-old-1/Library/uninstall-devtools --mode=all
sudo tmutil enablelocal
At this point, the /Developer, /Developer-old, and /Developer-old-1 folders were deleted. I then emptied the trash and reinstalled XCode. Everything seemed to be going fine, but when I launched XCode, it immediately crashed again 🙁
However, three additional bits of information:
-
The Problem Details in the Problem Report when XCode crashes appears to be basically the same as the Problem Details reported above.
-
The version of XCode that gets installed is XCode 4.2.1 Build 4D502, if that matters.
-
I've now noticed that if I hit "Continue" in the Internal Error crash dialog, about 15 times, XCode becomes usable to the point of exploring the menus, etc., and only seems to bring up the Internal Error crash dialog again if I try to quit.
If anyone has any other ideas, I'm open to trying them. I'm starting to wonder if I have a hardware problem somewhere or if I should downgrade to Snow Leopard and XCode 3.
