OS X 10.10 Yosemite - Dell E6230

[Hervé]

For the USB ports, try the following:

• remove AppleHPET kext from /S/L/E (keep a backup somewhere)
• rebuild cache with Terminal commands sudo touch /S/L/E + sudo kextcache -Boot -U /
• reboot

Jake when you updating your guide to include yosemite )

Here you go. Bootpacks are on the 3rd post

Champion!!

This did the trick! Thank you so very much.

 

Now for the pesky audio!

Edit: Tried with the latest bootpack AppleHDA.kext and still no luck

[Jake Lo]

Define "no luck".

Did you try boot pack from link on post #22 above?

if you're testing if you hear sound while increase and decreasing volume, that won't work. Yosemite no longer does that. You can test by playing something with sound or launch configure speakers from Audio midi setup.

No luck meaning it is still not working and I did not try the entire bootpack, just the AppleHDA.kext.

Should I try the full bootpack?

 

In the 'audio' and 'audio midi setup' Apps I only get the AirPlay device that is in the house. No sound from speakers connected via the 3.5m jack or the inbuilt speakers.

Did you enable kext-dev-mode=1?

[fwiz]

As far as I can tell yes:

DSDT layout-id set to 12 (hex=0x0c)?

DSDT layout-id set to 12 (hex=0x0c)?

 

I am not to sure how to check (a bit of a novice unfortunately). Does any of this information help?

 

I didn't want to flood the page so I hope this pastebin will help - http://pastebin.com/7kSZkytf

 

edit: If it helps at all I installed everything via multi-beast. (lol @ multifail auto correct)

 

edit 2: After more playing around I found out how to view and edit my dsdt.aml file. I believe it is set to 12 as can be seen here:

            Method (_DSM, 4, NotSerialized)
            {
                If (LEqual (Arg2, Zero))
                {
                    Return (Buffer (One)
                    {
                        0x03
                    })
                }

                Return (Package (0x06)
                {
                    "layout-id", 
                    Buffer (0x04)
                    {
                        0x0C, 0x00, 0x00, 0x00
                    }, 

                    "hda-gfx", 
                    Buffer (0x0A)
                    {
                        "onboard-1"
                    }, 

                    "PinConfigurations", 
                    Buffer (Zero) {}

Go ahead and replace all files with my boot pack since I don't know what you have and what build process you're following. Install latest Chameleon loader if you're using something else. I only tested on Chameleon, not sure if it'll works for anything else.
