Is Mac OS Big Sur working with QB Mac 2020?

I got some information regarding this matter, sw1953.

Currently, the supported versions on macOS 11 Big Sur are the following:

• QuickBooks Desktop for Mac 2021 R3 and later versions.
• QuickBooks Desktop for Mac 2020 R6 and later versions. 

Intuit is still working on this to ensure that the program works as designed when using the new operating system. You can use this link for reference: Intuit’s support policy for QuickBooks for Mac running on macOS 11 Big Sur.

You can update the release version to ensure that you have the latest one. You can follow the steps in this link to do it: Update QuickBooks for Mac to the latest release.

We got your back if you have additional queries about these updates. Have a great day!
