Did your iOS 17 Simulators get deleted recently?

The macOS anti-malware system XProtect got an update a couple of days ago, XProtectPayload 132, it found a false positive in the simulator runtime disk image and so would try and eliminate it. An updated 133 is out, check for updates and it should download the security update.

@AshtonDev It didn't seem like there was any way to actively download an update, but I checked via this method: https://discussions.apple.com/thread/254793873?answerId=258939159022&sortBy=best#258939159022

and found that it had been silently updated to 133.

XProtect not updated? - Apple Community

@designatednerd oh thanks for sharing that. I think we got lucky that we got the update pushed to us as we scrambled around trying to update all the macs 😂 I think these updates progressively rollout.

@designatednerd no idea if this actually works or was just a coincidence

sudo softwareupdate --background --include-config
