Apple to Pull 'iDOS 2' DOS Emulator From App Store Thursday July 22, 2021 3:22 pm PDT by Juli Clover iDOS 2, an app designed to allow users to play classic DOS games, will soon be pulled from the App Store, the app's creator said today. According to iDOS developer Chaoji Li, he tried to submit an iDOS update with bug fixes to the App Store, but was told that the update was rejected because it violated the 2.5.2 App Store guideline that says apps cannot install or launch executable code. During review, your app installed or launched executable code, which is not permitted on the App Store.
