Thanks all for responses! To clarify, I have a late 2012 imac currently running Mojave. VW is sluggish, but so is everything else. I need a new Mac. Perhaps I will keep this old machine just for VW. I do worry however about the potential for a crash and burn event, which we know would likely occur mid-project at a most critical moment! 2021 VW also an option, but not exactly rolling in the dough at the moment...... There's also the learning curve with new VW that makes me nervous.
