Release 2020.2.3 fixing launch issues for macOS Catalina/Mojave

[TParsons]

Hi Lucy,

This is one bug we missed, a few people have spotted it! I’ve pushed a bug fix to the next release, in the meantime here is a solution from another thread which will fix it for you in the short term:

New version of Psychopy doesn't compile script

**I also encountered a similar problem in the MacOS as below** **================================================** **Traceback (most recent call last):** ** File “/Applications/PsychoPy.app/Contents/Resources/lib/python3.6/psychopy/app/builder/builder.py”, line 1185, in compileScript** ** File “configobj.pyc”, line 554, in __getitem__** **KeyError: ‘useRunner’** **============================================================** **and I cannot find userPrefs.cfg file anywhere**
