Review on Timetec 32GB Kit (2x16GB) Apple DDR4 RAM 2666MHz / 2667MHz for Mid 2020 iMac (20,1/20,2) / Mid 2019 iMac (19,1) 27-inch Retina 5K, Late 2018 Mac Mini (8,1) PC4-21333 /PC4-21300 MAC RAM by Rick Alexander

I bought this memory to upgrade my new 2018 Mac Mini. Apple charges an additional $600 to purchase a Mini with 32GB of storage installed. With this memory kit and some tools, you can upgrade the base 8GB model to 32GB for about $150 and save $450 (as of May 2019). Once the memory was installed, the Mini booted up and working properly, the system reported the correct amount of RAM on both the summary page and the details page (see photos). Now this is not an easy update. First, it requires three different torx keys of a slightly unusual size (keys have a solid key in the middle, a regular torx won't work). Second, working with a Mac mini (or any Apple product) requires precision and finesse, the cables and connectors are very small and you can break something if you're not careful. I used to work on old Minis so I knew what I was getting myself into. Fortunately, "iFixIt" provides detailed step-by-step instructions and a video of the process. You should watch the video to see if you're happy with the update (they rate it as 'moderate' difficulty). However, if you follow the instructions, have patience, and can get used to the small details, it's doable and will save you a lot of money. All in all a very productive and economical upgrade and everything works great!
