App Store Crashes - Max OS X 10.12.4
Hi There,
For a little while now my App Store on my iMac (Mid 2011) has been crashing every time I try to start it or when I choose 'Install Now/Restart' when a notification pops up. When I click the Apple icon to try updating, App Store does not start at all. I have 2 updates that are sitting there waiting, but I can't update because App Store just crashes. I have done restarts etc., but I can't open App Store and therefore can't update anything.
When I click on the 'Send Report' link, the Specific Information says:
Application Specific Information:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[CKUpdateController observeOSUpdateScansWithProgressHandler:]: unrecognized selector sent to instance 0x618000270380'
terminating with uncaught exception of type NSException
abort() called
Is anyone able to help so that I can update my computer?
Thank you
iMac, OS X Yosemite (10.10.1)
