Sad sounding, but just the way it is.On November 12, 2020, Apple released its new operating system macOS Big Sur 11 that succeeded macOS Catalina 10.15. But I've found most developers, even if still active, can't even recompile their older software let alone fix it. This is an unfortunate move by Apple, who could easily provide an emulator, but I assume it's to give developers an impetus for people to move iOS apps to Mac, just as having only USB-C plugs gives manufacturers a reason to make USB-C devices.įor current software under active development, this is not an issue. I've found than even some of the simplest 2D apps I've tried simply crash and exit, 'cause they all still try to do something graphical. The reason is that Apple doesn't provide an accelerated 3D API to emulators like VMWare Fusion and Parallels, and there is no software fallback API. A good reminder that we should hold off buying new Mac Hardware when Catalina is first released until we have a proven set up working with Catalina - 'cause new Macs won't support Mojave.Īnd I can't spread this news enough - running your old 32-bit MacOS apps in an emulator DOES NOT WORK, so if this is your backup plan, abandon it now.
