Best performing MacOS to run for Early 2015 A1502 2.9Ghz 16GB Macbook Pro?

[se93]

Greetings to all,

I just received my Samsung 870 Pro 2TB SSD and wondering what MacOS you would recommend as the best performing / most reliable to go with?

The stock Apple SSD came with High Sierra. I’d like to run a MacOS that is directly compatible/installable without the use of OCLP for the moment.

I have nothing against OCLP, just that with this first ever MacBook I just acquired, I’d like to run it with no patcher for some time with the best applicable MacOS.

Your recommendations / feedback is appreciated.

Regards,

Mark

Monterey is the last macOS that the machine runs, install that.

Monterey is the only OS dat still receives security updates. And it doesn't need open core.

Is it me or is Monterey a bit slower than High Sierra on initial startup?

Perhaps, but once you can start using it it's OK The Samsung T7 is slower and takes a bit more time to boot. I had a MacBook Pro 2015 mid in the past and it performed well with Monterey on the internal SSD.
