Correct procedure for erase and restore
Hello -
Problems too numerous to mention! Crazy behavior from my laptop, so I decided to erase the hard drive and reinstall the OS. Shouldn't this solve most problems, other than those caused by hardware? Windows are opening and closing on their own, the dock hides and remains hidden even when the mouse is placed at the bottom of the screen, my third monitor has ceased to function, etc. I backed up to Time Machine. Then booted to command-R, chose disc utility, and clicked on erase. Reinstalled the OS, which seemed to go smoothly. I then rebooted while holding shift. Chose restore from latest TM backup. I don't know how this works, is it restoring the entire hard drive, including the system files that I just downloaded from Apple? Once I did the time machine restore, all my files returned, along with all the crazy activity. Logically in my mind if I reinstalled the OS and then just my data and apps from time machine, I shouldn't experience the same issues, right? Did I do this incorrectly? Help!! Thank you.
