Thanks for letting me know the V19.0.10 R11 is compatible.. I'm in no rush so staying with Big Sur for now..What is so confusing is all the posting saying that 

Release 13 (R13) November 2021 is compatible and is the latest version.. Is that release for a different version than QB Desktop Mac 2020? it would be nice to have a lovely table that says

Product  Then Latest verion for each product ID

Also having the product name 2020 and the Verison 19? That is very confusing  Thanks
