imac os x 10.8.5 the app store is temporarily unavailable
I've been battling for the last several months an issue with not being able to update my iMac.
The only way to get updates to work is to boot into safe mode.
I've tried so many different suggestions....many regarding spotlight, and nothing has worked.
I'm to the point where I'm ready to format and reload OS X. I really want to get to Yosemite but I don't want this odd problem to come along with the upgrade.
Here is the log from the console when I start the app store and then click update. I sure hope someone can help! Otherwise I am reloading OS X
