My Mac was stolen.
I bought an iPad to use find my Mac. The computer was going online and I was getting notifications. Unfortunately I was not at my iPad at the time.
After the Sheriffs office got my computer back it was completely wiped out. I had to put in my passcode to reinstall the OS.
My question is after the computer played a sound I suspect it was then erased to avoid detection. After the Mac was erased, could the Mac ping online while the thieves attempted to reinstall the OS without my passcode?
