Hello,
I think this deserves a fresh new post. The user interface for Mac CADD LT 2021 download can result in an error on installation. Although no error number pops up, it won't install. After going round and round for the past few days, my system needed a direct download from the browser. There is something that could be timing out - or missing in the download. Not sure - on my system, it bounced the boxes and then quits.
My system is a Mid-2010 iMac High Sierra 10.13 and the 2021 Mac CAD LT does work on it. My computer has a new flash drive. Hope this helps!
Cheers! 🙂
Tricia
