Try this for Wireless

AR9565

Not sure what bluettooth it has. Check under USB section of SysInfo for productID and VendorID

 

For audio, I'm not seeing AppleHDA_ALC283.kext in the output you have posted above. It needs to be cache in order to work.

I also see error 77. Rerun the commands until you see AppleHDA_ALC283 or reboot and then run again. Might take a couple of reboots

Should see a successful rebuild of cache without error

 

sudo chmod -Rf 755 /L*/E*

sudo chown -Rf 0:0 /L*/E*

sudo touch -f /L*/E*

sudo kextcache -Boot -U /

Regarding rebuilding of cache, all is explained in the FAQ section:

[lucky9]

Hi Hervé, thanks for the link. 

 

Hi Jake, sound problem got solved, I installed VoodooHDA 2.8.6 and it worked although I tried your solution couple of times but it didn't work (I restarted and build cache couple of times as you suggested.)

 

After I fixed the sound,  restarted to rebuild cache from terminal, and I end up getting these.

kextcache updated critical boot files, requesting launchd reboot

 

Although, I rebooted and rerun those commands to rebuild the cache but it again ended up with the same result posted above.  

 

please find the screenshot of the USB section attached. 

 

Please also guide me how to work with AR9565 file. 

as its written there : " please don't use it with KextsToPatch because it might not work..."

 

How, do I install these files? Should copy these to internal EFI partation kext folder 

and  to system / Library/Extension folder and rebuild cache ? 

 

Edit:    I left laptop for 15 min unattended and it went to I guess in sleep mode..  Had to shut down form the power button. . 

I see during boot, wake form Hibernation : no 

 

 

[Jake Lo]

See FAQ regarding Hibernation

I'm not seeing any Bluetooth in the USB section, are you sure this card has bluetooth combo?

Add this Config to /EFI/Clover.

During Clover boot, go to options->Config and select to boot from this Config file.

If it works for the Wifi, then you could rename it to Config.plist replacing the old

config-AR9565.plist.zip

[lucky9]

Yes it has bluethooth, it worked earlier don't know how, when it worked I see Ethernet and  bluetooth option on network. 

 

When I boot from the config-AR9565.Plist I see black screen.

[lucky9]

Hi! a little update,  

 

I copied the following under kextstopatch inside config.plist file and restarted..  The bluetooth showing up. But with a problem of not able to connect to devices any suggestions? 

And wifi is still not working.
