You can buy the Desktop CD or the Download program here,

Or buy it in stores or online like at Costco, Amazon, Sam's etc. The CD has both the Windows and Mac programs on it. If you buy the download be sure to pick the Mac download.
You can transfer your 2022 from Windows to the Mac program. You just need to copy the .tax2022 from the old computer to the Mac. It should be in your Documents in a Turbo Tax folder. Or search your computer for all files ending in .tax or .tax2022 etc. You might want to copy all the .tax files and pdf files from prior years to have them on your Mac. If you haven't done it you should open all your prior returns and save them as PDF files.
OR have you also used the separate Business program? (not to be confused with the Home & Business program). That is only for Windows. You can't install it on Mac.
