hmm, just a regular user here. not sure how I was allowed into this forum, but I have a question anyway. software update in my AppleStore won't download the latest iMovie because it says I need MacOS 10.15.6 I had autoupdate on, and I actually unenrolled in the public beta a long time ago. so I'm not sure why whichever 10.15 beta I have won't allow the latest commercial update. then when I tried to re-enroll on the public beta program expecting Big Sur beta, the same 10.15 beta was installed. I'm on a Late 2012 imac. The funny thing is all the other "iLife" apps updated without a hitch
