if you want easy install of MacOS , i suggest you install Mojave on a fast NVME and you will enjoy your MP5,1 very much.

if you need then newer software, you can still upgrade to Catalina (with help of Dosdude1 Catalina Patcher).

if you still need / want newer software, MacOS, you would have to install MacOS via Opencore; but would suggest you do that on a second drive, if you have never done it before.

an easy way to start is via OCLP
