issues running turbomac on opencore-patched 2012 macbook pro

[samallman87]

2012 13" macbook pro (9,2)
2.5 GHz Dual-Core Intel Core i5
Intel HD Graphics 4000 1536 MB
16 GB 1600 MHz DDR3
macOS ventura 13.6.1
battery completely removed

SIP and authenticated root both confirmed disabled via csrutil status, after granting execution privileges to the installer and then running it, it makes its way through the majority of the script and then at the end it returns:

Executing: /usr/bin/kmutil load --bundle-path /Library/Extensions/TurboMac.kext
Unknown option '-c'

Installation complete. Approve the extension if a prompt appears, and reboot your Mac.

however no prompt to approve an extension appears. when running "kextstat | grep TurboMac" the terminal returns

Executing: /usr/bin/kmutil showloaded
No variant specified, falling back to release

D364749F-2160-3AE7-8381-7E3CBCF40418 <6 3>

running "sudo powermetrics" returns

**** Processor usage ****

Intel energy model derived package power (CPUs+GT+SA): 4.19W

System Average frequency as fraction of nominal: 47.89% (1197.28 Mhz)
Package 0 C-state residency: 27.68% (C2: 0.94% C3: 0.00% C6: 0.04% C7: 26.70% )

which shows that the cpu is still throttled to 1.2 ghz. any idea what's going wrong here? are there any special instructions for a system that's already been patched by opencore legacy patcher? this model macbook pro only natively supports up to catalina so ive used opencore legacy patcher to be able to run ventura. i know that this applies some patches to the GPU so im unsure if this somehow interferes with changes applied by TurboMac. if you need any more info from me please let me know

Try to :

• uninstall turbomac using uninstaller
• reboot
• reinstall
• reboot

I had similar issue installing with open core patched imac i think it is due to the afps snapshot being already mounted (busy) by the open core patcher last operation (i installed turbomac after the post install patch before rebooting and this probably created the problems)

Have you tried putting the kext directly in the OpenCore EFI folder?

Hi there!

I just tried with my mid-2012 MacBook Pro 9.2 and it's safe to say that this method works flawlessly! With Macs (or Hacs) that are booted through the OpenCore bootloader, it is actually much simpler to load any kext!

Just put the kext file TurboMac.kext in your OpenCore's EFI folder at /Volumes/EFI/EFI/OC/Kexts, and add it in your EFI folder's config file at /Volumes/EFI/EFI/OC/config.plist using OCAT or OCC, and restart - you're good to go!

After restarting, just launch Terminal and run sudo kextstat to see if calasanmarko.TurboMac is loaded there - it should be! Hooray!

See here:

If you're having any problem with adding kexts to OpenCore folder, just search for any basic Hackintosh guide, and they will show you step-by-step how to do that!

OK.. So I know what your problem really is.. It has nothing to do with OpenCore at all whatsoever..

It is actually the problem from #18

Which is to say, the kext version in the release section so far only supports 6th-gen CPUs or higher (!) while your computer has a 3rd gen CPU.

You would have to rebuild the kext from the above pull request so that it could work on your CPU.
