Is it safe to leave a Mac on all night during a OS Installation?

Hi We were wondering in the event that it’s protected to get away from a PC or Macintosh personal computer on many night while it’s putting in a
operating system

If you do have a no break or if there’s no power intermittency and also constant failure there is not any problem.

Why certainly not It’s harmless! and do not forget plug your plug throughout other wise it can run beyond battery.
