I understand that those who installed Xcode 4 via the developer site are able to uninstall via /Developer/Library/uninstall-devtools –mode=all, however I installed via the App store and there doesn't seem to be an executable with the word "uninstall" in the name anywhere in the Developer folder at all. Any suggestions on how I should go about uninstalling Xcode 4?
In our installs of xCode 4 from the App Store, we are able to use:
sudo /Developer/Library/uninstall-developer-folder
You must uninstall first the
sudo /Library/Developer/Share/uninstall-devtools –mode=all
It might be something else in your particular case so maybe you can try
locate uninstall-devtools to find where the script is placed.
Then you can find the version you need of xcode from https://developer.apple.com/downloads/index.action
IMPORTANT: If you are going to install a previous version of the Developer Tools, be sure to restart the machine after installing.
