Description:
after downloading MySql community server install package, I get an error message when I try to execute:

"mysql-8.0.20-mac0s10.15-x86_64.pkg" can't be opened because Apple cannot check it for malicious software.  This software needs to be updated.  Contact the developer for more information.

Security on Mac set to allow downloads from "other". 

How to repeat:
I have repeated several times.  I can not think of other things that might be interfering in my settings, but it could be something in my set up.  I use Malwarebytes, but I have tried this with both the "App Block" and Malware Protection turned off.

problem resolved with help from Apple Care.  The Apple "Gatekeeper", a hardware change on 2019 and later iMacs (and probably others) has new security chip.  We were successful in installing, but I never would have gotten through it without their help.

Worked for me:

MySQLWorkbench need Python3.7 Framework in /Library/Frameworks/

brew install python@3.7
sudo cp -r /usr/local/Cellar/python@3.7/3.7.10_2/Frameworks/Python.framework /Library/Frameworks/Python.framework
open MySQLWorkbench, it's work
