I knew there was something fishy going on with the Mac App Store this week.
See this from Daring Fireball:
Lost amid the FBI/iPhone encryption hubbub was another bad week for the Mac App Store — apps just stopped launching, with the only solution being to delete the app(s) and re-install from the store. Michael Tsai (as usual) compiled a thorough roundup of information and commentary.
I can honestly say that I’m done buying apps through the Mac App Store. It is maddening to launch an app and have to type my Apple password in over and over again or have to delete/reinstall the app altogether just to get it to work again.
Oh, and #FirstWorldProblems.
