El Capitan Beta with Dell XPS 13 9343 (Early 2015 Model)

[Chumanix]

I have successfully installed El Capitan on my XPS 13 9343, however I have 2 questions...

How do I make it so I don't have to have the USB drive in the laptop every time I want to boot in order to use Clover? I'm familiar with installing bootloaders in Linux but not OSX.

I am getting serious performance hits involving massive tearing and animations taking forever. I did not do the prealloc thing at the start of the guide, as I booted up the EFI shell and setup_var wasn't a command and I did not patch the AppleBDWFrameBuffer kext.

Can anyone help with these two issues? Thanks in advance!

I am having the same issue. Graphics in 'About This Mac' show up as Display 21mb, and animations are laggy and tons of tearing. Only difference is that I did apply the setup_var DVMT pre-alloc change. Any ideas?

How did you do that? If you tell me, I will try and post results with my setup.

I just followed the instructions given in the link about getting 5500 graphics to work. I made a USB and placed the boot folder on it (but not on root, because that gave me issues. I placed it in /efi/ and it worked. Then I typed in the commands in EFI shell, my variables were the same as OP's. 0x183 and 0x184. Each was set to 0x3

Alright, did the commands and I am experiencing the same issue. About This Mac reports 21mb of VRAM (it was showing this before setting the variables) and it's just as laggy as before.

hmm.. Are you on a QHD model, or 1080p? I am QHD, by the way.

QHD.

QHD.

Makes me wonder if this is an issue with the QHD models. How did you get your sound working? Even after applying voodoo, I don't have any sound output (or slider)

You have to do the 2 cold boot (turn it all the way off and back on twice) trick. This is to change it to HDA mode.

Thank you. I guess for now, we wait for someone else to weigh in, like RehabMan.

Also, this guy has the QHD model and it's working fine for him:
