Internal Server Error after OS X Update
I have upgraded with the latest OS X patch and now cannot open the "updates" tab in Apple Store. I get an "Internal Server Error - Read" message.
I have also noticed Simcity Complete Edition for Mac which was purchased in Jan 15 now seems to have reverted to a "beta" version after the upgrade.
App Store also will not allow me to login.
I am concerned because if this is a bug caused by the upgrade, now I cannot get to the upgrade page to download any fix.
Any suggestions?
iMac, OS X Yosemite (10.10.2)
