I’ve run Plex servers on Mac Minis (M1). Docker on MacOS runs well finally — the issues that were everywhere a couple of years ago are resolved.
It ran very well on the hardware. The OP of this post is right, 8gb is not enough in 2024; however I would also wager that the vast majority of commenters have not used MacOS recently or regularly. It is actually very performant and has a memory scheduler that rivals that found on GNU/Linux. Apple’s users aren’t wrong when they talk about how much better the OS is than Windows at using memory.
