Apps downloaded from Mac App Store are not working.
I just purchased 1Password from the Mac App Store and it is working great on my MacBook Pro. My wife wants to use the program as well. We have a family account through Apple, so she went to my purchased items in the App Store and downloaded 1Password successfully. Once it is downloaded, it will not open, the icon bounces once when it is clicked and then does nothing.
She then tried downloading a program from the Mac App Store that she had previously had on her Macbook, Evernote, and it does not work either, the icon bounces once when it is clicked and then does nothing. At first I thought it was a problem with 1Password, but now it appears there is some other problem.
She has one of the older plastic white MacBooks. According to the information on the machine, it is from late 2009. She is running the most recent software, Yosemite (v 10.10.5).
Does anyone know what the issue is and how we can get it to work? Any help would be greatly appreciated.
MacBook, OS X Yosemite (10.10.5)
