Playing GameCube games is completely useless in the macOS version.

[TechExpert2020]

While playing GameCube games in the Dolphin emulator works fine on Windows (and in the Dolphin core in OpenEmu, despite minor performance issues), the same doesn't go for the macOS version. The program starts up fine and it's responsive but when you're going to play a GameCube game on it, it doesn't load and instead gives you this pop-up error message that says "MemoryMap_Setup: Failed finding a memory base." and it immediately crashes and then gives you a pop-up message saying that the Dolphin emulator quit unexpectedly. The error message is really confusing, especially to those who are used to playing GameCube games in OpenEmu or the Windows version. There may be some way to fix this issue...
