Which disk should be erased for Factory reset?
While doing factory reset on my machine for troubleshooting of one support ticket, I chose Macintosh HD internal volume and didn't touch Macintosh hd-data while erasing data in disk utility, and now after reinstalling os on macintosh hd, i see macintosh hd-data has all the data which was for user before factory reset and no new data is being written to it.
Which volume should be erased from disk utility while factory reset- Macintosh HD or Macintosh HD-Data?
