com.apple.mobileSo formatted my ssd??

Same issue I've been fighting as above. Exact error message on all my devices. Mac HD apfs system volume is being reformatted on my MacBook Air M1, M2, and Mac mini M2 every hard drive has been reformatted by “apple.Mobile.So”

The brand new MacBook M2 was brand new the second one of two because I couldn’t erase and once activated the malware overtakes the system within moments and system processes that this fake Mac HD that’s running will open up hundreds of outside connections interesting thing is all disguised by applications like Malwarebytes, avast, clean my Mac. And will make plist files disabling any antivirus or anything that may detect what’s going on in the background. It’s worth noting there has been no Apple ID inputted, all comes through my SonicWall firewall. The only thing that I’m suspicious of iPhone 15 will not be restored through iTunes and gives me an error code that when looked up indicates the phones OS has been tampered and it is on the same network as all of these computers that are all running a fake OS! It pains me to say is I’ve been a member of the Apple family since the iPhone 4 but Apple just went from the most secure OS to the most insecure OS as of late I’ll be taking all three of these devices in and hopefully getting refund.

so all of my apps quit working last night, tried the usual troubleshooting stuff:

everything started running slow the last few days, with apps crashing more than usual (I only use this Mac Studio for music production) so I then enabled the security features on the mac and on iCloud Drive, and that is when things started going screwy, as mentioned above. now I c an get online and my messages app opens again finally, but im still missing some apps - when hovered over, the question marks still come up as the app, but the icon is gone, and im afraid to try and open them without messing something else up

Sounds like your drive is failing.

I would take it in—

This is most likely either from Apple's automated process of configuring the original file system or maybe from a remote wipe. It has not been reformatted without your consent since you received the Mac since that would have destroyed all data on the drive.

If you want assistance with any of this, then please start your own thread instead of hijacking another thread for something completely different than the OP's original issue/question. It is hard enough to help multiple users in a single thread even when the issue appears similar. It is best & easier for everyone to have individual threads.

Also, please use a bit of formatting since one long paragraph is hard to read. I stopped reading halfway through because I was getting lost & confused. Notice how I have used multiple paragraphs in my response? Or how the OP and @leroydouglas also formatted their posts?
