When the link to download the MAC version of AppStudio 8 eventually appeared in the “Check for Updates” panel, I downloaded it to my MAC Laptop running Sierra 10.12.6. When I try to install AppStudio 8, it goes through the “verifying AppStudio” phase OK, then stops. I clicked on the file “Show Package contents- Contents- MACOS- AppStudio” which opened in Terminal, and found the following:-

[Process completed]I wondered whether the problem was the need for updated
I don’t understand it, but guessed that I needed to install Python 3, since version 8 uses this. I have installed Python 3 (confirmed via Terminal; version 3.8.1), binned AppStudio 8, restarted the laptop, and reinstalled AppStudio 8, but the problem remains. And the message shown above is still there, and exactly as before!
Any suggestions? Is the problem Sierra 10.12.6 ?
