repair permission and rebuild cache

 

      sudo chmod -Rf 755 /L*/E*

      sudo chown -Rf 0:0 /L*/E*

      sudo touch -f /L*/E*

      sudo chmod -Rf 755 /S*/L*/E*

My apologies for the spoon-feeding guys. I am grateful for your time and your help.

 

I think this may be the correct results:

locals-MBP:~ localuser$ sudo chmod -Rf 755 /L*/E*
locals-MBP:~ localuser$ sudo chown -Rf 0:0 /S*/L*/E*
locals-MBP:~ localuser$ sudo touch -f /L*/E*
locals-MBP:~ localuser$ sudo chmod -Rf 755 /S*/L*/E*
locals-MBP:~ localuser$ sudo chown -Rf 0:0 /S*/L*/E*
locals-MBP:~ localuser$ sudo touch -f /S*/L*/E*
locals-MBP:~ localuser$ sudo kextcache -Boot -U /

I'm rebooting now. Will post results.

Still no audio

 

 

Am I missing something in my config.plist perhaps?  Jake, I'm using the one you provided as a bootpack earlier in the thread. I only edited in my own SMBIOS details.

Try the kext i attached a few posts back.  It shouldnt make a difference, but every one ive seen is named AppleHDA275.kext and not AppleHDA_ALC275.kext.  After installed, repair permission, rebuild cache, reboot.

I think sleep is slow on this system, how long did you wait? Once sleep the front LED blinks really fast.

Perhaps it is sleeping.  After a while the LED blinks slow.  As soon as I open the lid, its back on immediately.  If i sleep from menu I have to hit the power button to get it back up.  Makes sense.

[Jake Lo]

Yes, that's normal, wake from keyboard or mouse doesn't work.

No luck with AppleHDA275.kext

[Jake Lo]

stick with one or the other, they are both the same except AppleHDA275 is set to layout-id 3 and AppleHDA_ALC275 is set to layout-id =28

if you use the AppleHDA from my bootpack, make sure you use the DSDT and Config from mine as well, if you use theSuffering, make sure you use all his files.

I'd updated the files here

Added Ulysses31's Cypress Touchpad kext and preference pane. It's a bit sensitive to touch though, but 2 fingers scrolling and tapping works.

[thesuffering]

a little sensitive?  lol i had to revert back to the basic one.  I couldnt handle how sensitive it was.  Although 2 finger scrolling was so nice to have.

[Jake Lo]

I already checked the preference, no option to adjust. Must be hardcoded somewhere, but not so obvious when I checked the info.plist of VoodooPS2Trackpad.kext
