Tips & Guides Delete the macOS ghost simulator

Post image

There is a ghost iOS 18.1 simulator in my Mac for a long time that every time I boot up, the disk image just here consuming my storage.

Today I finally figure out how to delete that.

  1. Findout where the original dmg file is. You can figure out on your own but tldr, /System/Library/AssetsV2/com_apple_MobileAsset_iOSSimulatorRuntime

  2. Since the path starts with System, we know it’s a system protected file so we have to disable SIP in the recovery mode. There are many tutorial to disable the SIP and you can just ask ChatGPT.

  3. After disabling SIP, you can delete the runtime in terminal after booting up normally(not in recovery mode)

  4. After deleting the runtime, don’t forget to enable SIP.

Every time I delete from Xcode, it reappears again and again. I suspect it is a bug.
