In order to successfully control a conditional loop, I am attempting to update my Psychopy Version on a Mac (as suggested in other posts). My old version was 2020.1.2, which I deleted (on a Mac).
I believe the issue was just on the Mac and I believe it is merely reporting the wrong version number (but is actually the correct 2020.1.3 code).
If you want to verify you could check one of the fixes. e.g. there was the commit below added in 2020.1.3 where importConditions now checks a couple of different. So you could open psychopy/data/utils.py and search for _attemptImport (which didn’t exist in 2020.1.2)
