Mac Is Taking Too Long For Installing Os High Sierra

admin

  1. After the long download and during the install the system just kept restarting. Second attempt, i used the recovery mode to check disks and to attempt reinstall the OS. I had the same results as the first. So, I deleted the HD and attempted to install fresh OS; however, the Internet recover will no longer load.
  2. Now for over 18 hours, I'm waiting on OS X Mavericks to finish installing on my computer which is under 2 yrs old. Oh, after the initial stage of 'installation', the download and install, which took like 4 hrs, the computer rebooted (as was expected according to videos on yt).
