Give a little help for a fellow tech newbie
He probably used a USB drive to boot into Linux, then switched back to Mac OS by removing the USB. The computer shouldn’t automatically go back to Mac when you take it off, but it depends on how it was set up. If you’re a tech newbie, just be careful with USB connections.
Linux supports running from a Live Disk without installing software locally. Once you use it, the system remains unchanged until you restart and switch back to your main operating system. Simply power off, detach the disk, and turn it back on to resume normal use.
Similar to using a Windows to Go drive, you can start your own Windows on any machine without needing a BIOS lock. It feels like you’ve never turned it off or unplugged the drive before. If you’re worried about this happening, consider setting a BIOS password (to stop changing boot order) and encrypting your drives—even if they still attempt to access data. For Macs, I’m not sure but there might be a comparable method available.
