E6220 Guide for High Sierra

Recommended Posts

Hi there. I haven't seen a guide to install High Sierra on E6220. Should I try the Sierra instead? Is that how it works like trying the previous version?

 

Thanks.

There are several guides for Sierra. Here or here for instance.

 

For High Sierra, you'll need Clover because Chameleon/Enoch do not support 10.13's temporary-partition installation. Same for the updates. But Chameleon/Enoch do boot and run High Sierra without issues. that's how I run it and I use my Clover USB installer whenever there's a High Sierra update to install. Other than that, installation is the same as per previous OS X/macOS versions.

 

Here's the Clover EFI folder I use on my 10.13.1 USB installer set with Clover r4081. BIOS runs in legacy mode.

EFI_E6220.zip

 

No problem updating to 10.13.3 and booting the temporary update-completion partition with that same USB installer.

Herve, that worked perfectly!!! I was able to install in two machines E6220 without any issues. I had opted to High Sierra + Clover + your EFI package. There is only one issue regarding the boot. I installed Clover in the HD and copied back the EFI folder, etc. However, every time I boot the system I get stuck on the Apple screen logo even before it starts loading. 

 

I accessed Clover boot options and added a -v, and that worked. Without -v it freezes, with -v the boot process works fine. 

 

Weird right? -v is just the verbose mode, I'm not really changing any config parameter!!

 

Any thoughts?

 

Thank you for your help.

 

Mario.

You could try to move the add-on kexts to /L/E, repair permissions and rebuild your cache. Don't subsequently keep the add-on kexts in the Clover EFI folder.

Absolutely. You can then boot High Sierra through Enoch but all updates will require that you use your Clover-based USB key to finalise them. That's all.

Man that is awesome, very cool .... the high res in my Sierra is flakey so I'd be running the low res mode anyway and I can go to High Sierra to handle some debugging.
