Category:MySQL Workbench Severity:S2 (Serious)
Version:8.0.24 OS:Mac OS X (10.15.7)
Assigned to: CPU Architecture:x86 (x86_64)

Description:
https://dev.mysql.com/downloads/workbench/

The text states "Packages compatible with both Big Sur (11) and Catalina (10.15)"

However, the downloaded package is only compatible with MacOS 11, and gives you an error saying you need MacOS 11 to run it when running it on 10.15.7.

How to repeat:
1. Use MacOS 10.15.x
2. Go to https://dev.mysql.com/downloads/workbench/
3. Download the dmg file
4. Open it
5. Observe the "prohibited" symbol covering the application icon
6. Drag app to the Applications folder
7. Try to open it
8. Get error "You can’t use this version of the application “MySQLWorkbench” with this version of macOS. You have macOS 10.15.7. The application requires macOS 11.2 or later."

Suggested fix:
Either build a universal binary that works on both, or remove the 10.15 compatibility statement from the download page.

I'm seeing this as well. Also, to make matters worse, even after I remove MySQL Workbench 8.0.24 and reinstall MySQL Workbench 8.0.23 on macOS 10.15.7, it now keeps crashing immediately. I suspect the temporary installation of 8.0.24 did something to my system that now makes 8.0.23 fail to run.

Following the steps in https://bugs.mysql.com/bug.php?id=102364 solved my problem with downgrading to Workbench 8.0.23. No idea why I *didn't* have this problem before I upgraded to 8.0.24, but I wonder if 8.0.24 made permanent changes to how Python 3.7 is accessed.
