At work we have one Mac laptop that everyone uses to compile and test our iOS app. The employee who originally installed XCode used his personal Apple ID, and has since left the company.
When I log in to the App Store on this PC, I can download new apps (including the Mavericks update) but when I try to update an existing app, especially XCode, it always brings up the login prompt, with the user id field disabled and prefilled with his Apple ID.
Can I update XCode without his Apple ID password?
