I spent roughly 8 hours all told downloading, installing, and updating Xcode, much of which could have been bypassed by following two simple rules:
- Never update Xcode from the Mac App Store
- Wait until Apple posts the upload on developer.apple.com/downloads and then update from there.
Under such circumstances, you’ll always be better off downloading the bossy full-figured 5GB dmg than upgrading a model-thin Chanel-wearing 2.6GB differential, especially when servers are mocking you with NananaNAN completion estimates.
This is why you should always wait for a DMG. No matter how long it takes to appear on the developer site. No matter how slow the download ends up being. The advantages of downloading a DMG are numerous[…]
Seconded. I have nearly always regretted updating Xcode via the Mac App Store. And you’ll probably want the .dmg file to save a copy of that Xcode version, anyway. (I wouldn’t count on an archived copy from the Mac App Store to keep working.)
