Follow the Clover guide linked from the FAQ.

http://www.tonymacx86.com/el-capita...faq-read-first-laptop-frequent-questions.html

Pay attention the Broadwell (and DVMT-prealloc) info in the FAQ. It is important.

Well... i don't understand, i don't have option in the bios for dvmt-prealloc
Should i hack the efibios ?

I don't know what to do at this time. As said i'm a totaly noob in hacking/patching file

If someone can help me i could give him a reward to have my laptop hd5500 working with the correct framebuffer...

Ok i found how to modify the bios. I changed dvmt 32mb to 64mb, i flash the modded bios, cross my finger, and reboot.
Ok, i activate "AppleIntelBDWGraphicsFramebuffer39CFEB3C"

but i still have the framebuffer driver error at boot....

No need to patch for minStolenSize if you set DVMT-prealloc. In fact, if you use the wrong patch, you can reverse the logic of the assertion, such that you get the panic with the correct DVMT-prealloc setting!

Ok i disable the patch. still "fail to register framebuffer driver"
I increase the DVMT-prealloc to 96mo, still have the same result : "fail to register framebuffer driver"
My smbios is set to MacBookAir7,2 with the right serialNumber...

Should i try to patch dsdt/ssdt ?

Boot verbose, show photo. Attach EFI/Clover folder as ZIP (omit 'themes' folder).

There it is.
Thanks you for the help

ACPI is not patched correctly. Remove all files in ACPI/patched ...

Also, verbose boot looks very messy (lots of problems with kexts)... Try fresh install.

I just finish to do a fresh install, this is the same result : "fail to register framebuffer driver"
