Help upgrading my 27 inch iMac from 2013

Start by upgrading your RAM, and if it has a hard drive, switch to an SSD.

External SSD first, then use OCLP. You can always wipe the SSD and go back to High Sierra if needed. After that, upgrade your RAM. The SSD will make the biggest difference. RAM may not be as noticeable but will still help.

Thanks, I think this is the way to go.

Check out Mr. Macintosh’s YouTube channel. His OCLP tutorials are really helpful.
