I use a MacBookPro (9,1), late 2012 model with 16 Gb memory, 480Gb SSD, Intel I7, MacOS High Sierra with Infinity photo and Luminar 2018 & Luminar 3. Works great.
I've purchased several 2012 MacBooks and rebuilt for family members. It's the last year to allow RAM and Hard Drive to be easily replaced. Like yours I max out the RAM and install an SSD, they run great and that year also had the DVD drive.
