A Sierra installer I downloaded last week was corrupted. It wasn't obvious at first since I was able to create a USB installer and the USB stick booted fine. But after an hour of proceeding I had issues in MacOS installation process, I got a message that says my installer was corrupted. I downloaded it again and after one more hour it is working fine.
When downloading Linux ISOs, most (perhaps all) distributions provides an MD5/SHA1 code so I can check my downloaded copy with those.
So is there way to check for the integrity of Mac AppStore downloads? I'm not so concerned with small downloads but very with 1+GB ones which could waste hours of time.
