Welcome to the Magix Sound Forge users community @Derrick-Fields.
There is no 'end-of-support' date on this usersforum and most issues can be resolved going back to the Sonic Foundry versions, The Magix end-of-support date is kind of a gray area. I would speculate (Sony) Sound Forge 11 and earlier versions are no longer 'officially' supported. Email Magix for a definitive answer.. if there is one. infoservice@magix.net
Magix is usually very accommodating 'and may' swap the PC version for the Mac version. No guarantees though. Email infoservice@magix.net or sales@magix.net and ask. That said, I think development has ended for Sound Forge Mac. Read Jeff's sticky: https://www.magix.info/us/forum/osx-catalina-and-sound-forge-mac--1244059/
