Reference the steps below to learn how to convert a QuickBooks file. For that reason, it is sometimes necessary to convert a file from the Mac version to the Windows version, and then back again. Thanks.Because QuickBooks for Windows and QuickBooks for Mac use different types of databases, there is not an Accountant's Copy feature available in the Mac version of QuickBooks. They claim you have to be running Big Sur and have QB2019 R10 for it to run properly.Īgain, PLEASE PLEASE PLEASE help us QB2019 users out by redownloading and installing QB2019 R10 onto your Big Sur upgrade and confirm it will load the QB2019 database you have. It is a matter of waiting for it to be announced. I might consider this as well although QB2019 is covered for MacOS system upgrades for three years and they know this. It will load your database from QB2019 (or it can be converted to proper format). You can get by calling their Sales people for the Mac and pay $399 for that version. They also have QB2021 which they say runs under Big Sur but they hide this desktop version well and it is hard to find online. Intuit wants us to use the online version of QB for a much highly cost since it continues monthly. By the way, going back to Catalina is not trivial and unless you have a Time Machine backup it will be very troublesome for you. That is why I ask for your help since as a user you might confirm this for me and lots of others using that BLOG topic. The QB Admin people skirt around the issue and do not directly confirm what I told you. Look at the link below and PLEASE PLEASE PLEASE tell me this worked since I have NOT updated to Big Sur although I did update to QB2019 R10. You should be able to run QB2019 and it should open that database. Your QB database should still be on your computer running Big Sur. If not, you should be able to log into your QB user account and download a copy of R10 and use your license number to activate it. Did you perform the QB update BEFORE upgrading to Big Sur? QB2019 versions below R10 will not run under Big Sur. I believe that if you had upgraded QB2019 to R10 that it would have run under Big Sur.
