Chosen Solution

Hi all, I am trying to upgrade my Mid-2012 Macbook Pro so I started by erasing my hard drive. I am a noob 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 and faster….., 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? Thank

If you have an external Time Machine backup, do a restore from that. If not go ahead and install the Lion, then download and install the Mojave. Get an external backup drive!
