Help I deleted my hard drive  

   RSS

0

Hi all,

I am trying to upgrade my Mid-2012 Macbook Pro so I started by erasing my hard drive.

I am a rookie so I messed up and didn't realize it would delete my OS also. I was on Mojave. 
Now, when I do CMD+R at startup, it only offers for me to reinstall LION. 

Does anyone have any advice?
I really would like to be on Mojave because it is much better..., right?

I'm planning on putting in a new battery, a Samsung 860 EVO SSD, and 2x8GB of Corsair RAM after that.

Does anyone have any good advice they can offer in this situation? Thanks

I haven't tried this, but, according to:  https://www.macstrategy.com/article.php?45

  • Command (⌘)-R : Install the latest macOS that was installed on your Mac, without upgrading to a later version.*
  • Option-Command-R : Upgrade to the latest macOS that is compatible with your Mac.**
  • Shift-Option-Command-R : (macOS Sierra 10.12.4 or later) Install the macOS that came with your Mac, or the version closest to it that is still available.

An alternative, would be to first install Lion and then upgrade. MacTracker claims that your 2012 MacBook pro is compatible with Mojave.
