The Desktop software (CD or Download) is for all computers either desktops, laptops or notebooks that run full Mac or Windows. So your MacPro will need the new Mac OS to use the Desktop program. If you can't install the Desktop program, you can use the Online version.
If you switch to the Online version you can transfer your 2023 return done in the Desktop program to the Online version. Post back next year if you need help transferring.
If you used the Desktop program before you may notice several differences and not like the online version. It has less features and no Forms Mode. You can only do 1 return. Your return is only saved online so be sure to save both the .tax2023 data file and the pdf file to your computer when you are done. In case you need to amend in the future or if you need a copy to get a loan or something. You might not be able to access your online return when you need a copy.
