As far as I can tell, it&#x27;s not universal, but still somewhat common. (My computer has always done it ever since I bought it new in April.) It is a bit annoying. But since I use the MAS so irregularly, I can get by. I do wonder what the cause is, though. I&#x27;m less certain I&#x27;d like to know how Apple have so far failed to get to the bottom of it.
