Why is there a strange Apple ID in my iPhoto update login?
2 days ago I upgraded my 2009 MacBook Pro to El Capitan. Today Software Update is asking me to update a number of apps, including iPhoto.
However, the iPhoto app is showing a strange Apple Id instead of mine and won't let me use my own Id to update the app. The only solution is to trash iphoto and reinstall.
No-one else has had access to my Mac. There is no malaware - just scanned using Malawarebytes. I keep my Mac locked with a password at all times when not in use. I work from home on a private network.
Apple Support was not able to shed any light on this but confirmed that the Id is a genuine Apple Id.
Has this happened to anyone else? Any idea how this could have happened?
MacBook Pro, Mac OS X (10.5.8)
