AetherSX2 is a PlayStation 2 emulator primarily developed for Android, but it can also run on other platforms via unofficial ports or compatibility layers like Wine or Android emulation. Unfortunately, AetherSX2 is not officially supported on macOS, especially on older Mac models. Even if you manage to run it through a workaround, older Macs may lack the necessary hardware capabilities—such as a powerful GPU or modern CPU instruction sets—to handle the intense processing required for PS2 emulation.
