You're welcome, consider it another aspect of your Hackintosh ongoing education... You try, you fail, you experiment, you learn. That's the idea; makes a break from perpetual spoonfeeding...
Indeed, Enoch does not do the AICPUPM patch that Clover did. You can read about EC-capable Enoch in this thread. You may attempt to boot in single-user mode and add NullCPUPM or the patched AICPUPM kext.
I see you're booting with an MBP4,1 SMBIOS, which is not the right profile for a Latitude E6420 with SandyBridge CPU and Intel HD3000 graphics. Using Chameleon Wizard, set your SMBIOS profile to MacBookPro8,2 and save the SMBIOS plist in your /Extra folder.
You'll also need a kernel plist in which you place references to injected kexts location and/or patches to use (a bit like Clover, but just a bit...). In the case of the SandyBridge platform, only 1 parameters is useful:
- KernelBooter_kexts (=Yes/No) -> tells Enoch to load (or not) injected kexts from /Extra/Extensions
Injected kexts will incur a sligghtly slower boot time than if kexts were placed in /Library/Extensions for instance, but it's a powerful way to test kexts: place proven kexts in /L/E and cache/prelink them; place test kexts in /E/E and inject them with KernelBooter_kexts=Yes.
Thanks for your guidance, Herve! Problem still exists, frequent freezing and graphic glitching.. going back to Clover as I've been working with this package for quite a while.. Peluco, have you experienced improved graphics behaviour through your work? Thanks.
