Please someone help. We were running El Capitain 10.11.6 but were having trouble accessing internet pages so upgraded to Monterey. Now Quickbooks 2015 will not open and all of my info is trapped. I am starting to panic. When i click on quickbooks it says the following:
You can’t use this version of the application “QuickBooks 2015” with this version of macOS.
I tried to use mac time machine to go back 24 hours but it will not allow me to run time machine due to the following:
"the system can't be restored onto this disk because HFS systems can't be restored to space sharing APFS volumes. Reinstall macOS on this disk then use migration assistant to transfer data from your backup instead"
any help would be appreciated as my small business info is trapped.
