Sonoma just updated again last night (11/16/23) I was able to open and use Quickbooks Desktop 2019 on my Mac again for the first time since the original Sonoma update happened! Thrilled as I almost purchased the 2024 QB Desktop version. The only problem I see so far is I am unable to backup either of the two companies I am running in QB's. If anyone has found a way to create a backup I'd appreciate the advice!
