I bought the QB Mac Plus upgrade before I actually upgraded to Big Sur. Old version works, new does not have all functions I need working.

After much hair pulling I finally was able to get it working after ignoring the registration window that came up as it wouldn't work. Not sure what I did but it did... I finally also figured out on my own that that the new version wanted me to re add my bank account registers. But, just so people will know...Mac version 2019 does work. I would definitely update and try it first before upgrading.
