Last September, however, he was encouraged to try submitting an update with document storage enabled, and Apple surprisingly approved it, opening up iDOS to a much larger world. Until late last year, however, iDOS 2 had largely been neutered by the inability to actually access anything outside its own sandbox, and the developer appeared to have mostly given up on it. However, it actually made a return about six years ago as iDOS 2, and for whatever reason it’s been allowed on the App Store ever since. It’s had a rough ride over the years, first briefly popping up back in 2010 before being unceremoniously removed by Apple, and then appearing and disappearing over the next few months. IDOS is an emulator from the days of old MS-DOS-based PCs.
