Apple initially rejected UTM SE, an app for emulating a computer to run classic software and games, as it violated App Store rules6. The company deemed that the app provided emulator functionality but did not emulate a retro game console specifically, which is a requirement per guideline 4.7.

Apple initially rejected UTM SE, but later approved it after the developer made changes to comply with App Store guidelines. The app now runs without Just-In-Time (JIT) compilation, which was a major concern for Apple. The AltStore team and another developer's QEMU TCTI implementation were instrumental in achieving this JIT-less build.
