[SOLVED] E7450 Mojave - various odd issues

Recommended Posts


Pretty new to all this lark.


Got Mojave installed on an E7450. After much manual messing about with Clover and installing various bits and bobs, I now have a part functioning system.


Wifi is fine, as I'd previously been running High Sierra on this and had already swapped out the wifi card.


On boot I get a very long pause, then    '[IGPU] Graphics driver failed to load: could not register with Framebuffer driver!'

then another longer pause


but, eventually it boots.


I've no:-  

- sound

- keyboard

- trackpad


Not even looked at sleep etc.


How do I go about diagnosing where my problem lies?


thanks folks

Many thanks fella.  I think I've followed those instructions to the letter.


I get the same error message during boot, and graphics seem no better - still corrupt in places.


Still no sound, keyboard, trackpad or LAN.


F2 and F4 clover dumps done and debug recreated.

Remove all the kext with dSYM in it. Not needed

You have added a bunch of *.efi drivers I did not ask to add

Go ahead and delete the following folders: drivers64 and drivers64UEFI

Under drives/UEFI, remove these:

  • apfs.efi
  • OsxAptioFixDrv.efi

Delete nvram.plist

No joy I'm afraid, still much the same as when I started.

EFI partition cleaned up as per instructions.


I just mount the EFI, make changes, then reboot right?

I only need to do permissions and kext cache rebuild if I touch /L*/E* or /S*/L*/E*?

EFI looks fine

check for these kexts in /S/L/E

  • AppleIntelHD5000Graphics.kext
  • AppleIntelBDWGraphicsFramebuffer.kext
  • AppleIntelBDWGraphics.kext

Those are needed for graphics acceleration.

Can't explain why sound, keyboard, touchpad and LAN are not working. I see all the correct kexts in the right places.

I would recommend you re download Mojave and create a clean USB installer with the well known createinstallmedia command

Use the current EFI folder you have now as the bootpack when you install Clover

Thanks so much Jake.  As you said I've taken a dump of the EFI package, and started from scratch.


This time it's worked a treat, and it's so easy just to drop the EFI folder onto both the USB drive and to the target install drive after install.


Just bluetooth to sort....
