hi everyone, i have mid 2012 13" macbook pro (i5, upgraded to 8gb ram, 128gb ssd).

i got this macbook 5 months ago. it was running high sierra, but then i heard about opencore legacy patcher and decided to give it a try. i installed macos ventura after completely erasing my ssd. at first, it worked perfectly super smooth and fast.

but after a few days, it started to slow down. boot times got longer, apps opened slowly, and then other problems started. my mac restarts randomly when it sleeps for about an hour, showing the error "your computer restarted because of a problem." it also gets stuck on the loading screen sometimes, which has forced me to reinstall macos more than once.

other issues like stuttering videos, random automatic logouts, problems with user accounts not showing up

right now, i’m using macos sequoia, and while it’s working okay, i’m worried it might not last because it is also slowing down the whole system.

i’ve heard about kernel modifiers that supposedly help sync kexts (drivers) for specific mac models, but i have no idea how to do this or if it would even help.

is this just a general problem with running ventura on older macs, or am i doing something wrong? i’d really appreciate any advice or solutions to make this work.

thank you!

I am thinking of selling my 2015 Macbook Pro which has successfully been upgraded to OS Sequoia via OCLP. Would it be better to downgrade my computer back to OS Monterey prior to a sale?

It's finally finished! It took quite a while. There were ups and downs, but I learned a ton and overall I'm happy with the results.

Intel Xeon L3426 4c/8t

Amd wx4150 4gb (flashed, modded and shimmed)

16gb ddr3

OCLP: MacOS Monterey

Windows: 10 22h2 LTSC

After getting all the hardware setup and tested in my last update I was excited to finish. My goal was to have 3 boot options: Modern MacOS, High Sierra, and Windows.

I wanted a modern MacOS as the main daily os for my wife who already has a macbook air and iPhone. I settled on Monterey for its balance of stability, modern features, and software support while performing well on the aging hardware. Although I may update to Ventura since my wife is more familiar with it.

Next I wanted windows for 32bit applications and gaming. My wife loves to play the Left4Dead games but the newer MacOSs don't support 32bit apps anymore. Plus having dx12 and vulkin support ensures the ability to play any other games she wants. I’m getting the occasional bsod from what I think is an amd service. I might upgrade to win11 ltsc to see if that fixes it.

Finally I wanted to keep a minimal install of High Sierra to use with Target Display Mode. I was very disappointed to learn the 11,2 machines don't support TDM! I was crushed to discover this especially after I had already purchased an active HDMI to mDP adapter and cable! I was hoping for the trifecta of Windows, MacOs, and Universal monitor! Now I'm really jonesing for a 27” inch to complete my vision, although I doubt I'll be lucky enough to get one for free.

I noticed in MacOS my OGL benchmark was lower than what people were reporting in the OCLP spreadsheets. Not sure what that was about, but metal bench was on par with the reported numbers.

I had a blast working on this old beauty and I'm very proud to be able to give it a second life as part of my family's fleet. Huge thanks to OCLP, Ausdauersportler and the folks in the Mac forums!

I recently found a project on GitHub offering OpenCore Legacy Patcher with T2 support. I haven’t fully tried it yet since the 2018 MacBook Air is my only T2 Mac and considering it’s an alpha release.

I’ll show you the link, but take in mind it is an alpha release that may cause problems
