What is the best and easiest way to get High Sierra or Catalina on my 2011 Mac.
I just erased my SSD for a clean start after a very buggy mac.
It appears to be forcing me to add LION OS now I want High Sierra or Catalina. Yesterday it was offering me High Sierra but now when I start in boot mode (CMD R) it only offers me LION. I am Not sure why now the day after it is only giving me LION. Do o have to add lion and then later upgrade to HS or CAT?
Any help welcome.
