Apple Mac software update asks to restart to install updates then goes to logon screen
Had this problem where a Mac software update asks to restart to install lots of updates , the screen goes blue & i got the spinning ball then the logon screen appeared, once i’d logged back in the updates were still waiting to install.
I installed the stand alone “Mac OS X v10.6.7 Update Combo” hoping this would sort it but still got the same result, after quite a bit of research i found that sometimes, Software Update’s caches and other support files can become corrupted, causing various problems while trying to update.
I deleted a file called Cache.db located in this folder /Macintosh HD/Users/YOUR USERNAME/Library/Caches/com.apple.SoftwareUpdate/
Ran Software Update again and the Software Update ran through without a problem. 🙂
