So I "got a copy" of the first GM of Mavericks about 2 weeks ago. Note: I do not have a developer account. The copy I got was on a popular torrent site. If I follow the links to download the official release (I had planned to install the final version over the GM... no moreso with a second GM release), I get prompted to open in the Mac App Store. From there I click on Download and it says: "OS X v10.9 is already installed on this computer. Use the Updates page to install the 10.9 update or if you would like to download the full OS X installer click Continue." If I click Continue, it pauses for about 3 seconds and then I'm prompted to sign in the App Store. The problem is the Apple ID is pre-populated with email@example.com and its greyed out. I cannot change it. If I type in a bogus password it says the account is disabled for security reasons and the option to reset the account, but again the ID is greyed out. If I choose the option to install the update, it shows 2 updates available (one is for the Java update from a few days ago; presumably the other is for OS X 10.9). However it only shows the "2" over the Updates button... the updates field itself is greyed out. So I can guess what happened... someone with a developer ID got the GM and torrented it and then got their account cancelled. I get it. But how do I get around this? I've tried all manner of ALT/OPT clicking, etc. Is there a plist file somewhere with the userid so I can delete it or insert my own? I've done this with GM's before and never had issues with Apple tracking or retain the account that was used to provide the GM. Heck... I've done this successfully with IOS GM's too. Anyone know any work-around's so I can successfully re-download the true 10.9 release under my own ID?
