Issue with Photos App - error message The application built with PhotoLibraryPrivate version 215.65.00 but is running with version 209.52.00
Hello, hoping someone can help with my sluggish MacBook Pro.
I am running OS X Yosemite version 10.10.3 and have tried to update to El Capitan 10.10.5 on a Macbook Pro 13inc Mid 2012. It has said it has already downloaded twice but when I open up the software it is still sitting at 10.10.3 with no changes, the download seems to be taking a long time - already been sitting for about 6 hours.
I am now trying to open the photos app but get the following error coming up - The application built with PhotoLibraryPrivate version 215.65.00 but is running with version 209.52.00.
Any advice on what the options are to get my photos app running again! Have tried various time machine backups and computer not liking this either 😟
