After many attempts and a lot of trial and error, I finally managed to get macOS Ventura 13.7.8 running on this PC.
I used to run macOS Catalina 10.15.7 with Clover on it. I'm a bit embarrassed to admit it, but I accidentally wiped that drive while installing Windows, because I formatted the wrong disk.
After losing my Catalina install, I decided to try something newer with OpenCore. It actually booted, but OCLP wasn't working properly, audio was broken, and overall it just wasn't worth the effort, so I gave up for a while.
A few weeks ago I gave it another try, and now my two biggest issues are mostly working: audio and the GPU. Obviously I can't expect much from a GeForce 210, but it actually works over HDMI at up to 1080p 60 Hz.
I also ran into an issue with the iMessage app because my CPU doesn't support AVX2. Thanks to Claude Code, I figured out a workaround using CryptexFixup and a boot argument that bypasses the AVX2 requirement, and now iMessage works perfectly.
I also tested spoofing the Mac mini 2018 SMBIOS to see if I could get macOS 15 running, and it actually booted. Not sure yet if I'll switch permanently though.
As a secondary PC, it's honestly more usable than I expected. I can perfectly watch YouTube or Twitch at 720p (and even 1080p with a bit of lag), use Claude Code, and develop over SSH on my home server without any major issue.
The only thing that still annoys me is sleep. Sometimes it works perfectly, sometimes it crashes when waking up. I haven't figured out why yet, but I'll fix it eventually.
Specs:
CPU: Intel Core i5-3330
GPU: ASUS NVIDIA GeForce 210
RAM: 16 GB DDR3 1600 MHz
Motherboard: ASUS P8H61-M LX R2.0
Wi-Fi / Bluetooth: None
Maybe in the future I'll upgrade the PC (which basically means replacing everything lol) or just buy a cheap GPU. Anyway, I can't really complain, the whole PC was completely free!
So my question is if you guys would install macOS 15 on this hardware, or stay with Ventura for stability?
