Hi, I downloaded previous beta but didn't install concerned about the bugs. So I waited until the GM to install beta version. GM was downloaded with no problem. But when mac reboots to install, it said unable to install, couldn't verify. This happened when I try to install previous beta on Parallel too. But I thought it was something with Parallel. Can anyone help? I used to install El Cap beta last year and unenrolled. Wonder if that's the reason?
