Graphics Acceleration works better as on 10.11.3, but not perfect. For example the menu bar at the top is always white and I can't read the font at the most time.
I hope Graphics Acceleration will work on 10.11.5 better.

Did you set DVMT-prealloc to 64mb?

Never heard about it. Where I can set this? I took a look into the BIOS, but there isn't any option about that.
 
Looks very complicated to work in BIOS. Don't sure if it's worth to risk to destroy something.:eek:
@SkullD3mon: Do you have the same issues or is everything working fine on your system?
 
In another forum I found the hint that I can patch the DVMT pre-allocated memory:
Name: AppleIntelSKLGraphicsFramebuffer
Find: 4139c4762a
Replace: 4139c4eb2a

How and where I have to patch this? In the config.plist? And by the way, how I can find out which size the DVMT pre-allocated memory is currently set?

Read the Clover wiki regarding config.plist/KernelAndKextPatches/KextsToPatch.

See also guide: http://www.tonymacx86.com/el-capita...de-booting-os-x-installer-laptops-clover.html

In the plist linked by the guide, the patch is present, but disabled.

After determining variable offset with BIOS extract/IFR extract, use setup_var in UEFI shell.

Yes.

Note:
Code: 
SPEEDY-OSX:probook.git RehabMan$ echo -n QTnEdio=|base64 --decode|xxd
0000000: 4139 c476 2a                             A9.v*
SPEEDY-OSX:probook.git RehabMan$ echo -n QTnE6yo=|base64 --decode|xxd
0000000: 4139 c4eb 2a                             A9..*
 
Ah base64. :D I was a little bit confused, but well, that makes sense. I will check BIOS and the patch later. Thanks for your great support as usual! :)
