Hello everyone!

 

I have finally been able to run and install Mountain Lion 10.8.2 on my Acer Aspire M5 laptop, and let me tell you, my laptop is flying fast!

 

The only thing is that I am unable to use my fn controls on my keyboard. meaning I cant change the brightness on my laptop. 

 

The only fn buttons that DO work are:

 

fn+F4 = Puts the laptop to sleep
fn+F6 = Turns off screen (In case you are using HDMI and both screens aren't on)

fn+F7 = Turns touchpad off

fn+F8 = Mutes sound

fn+F9 = Turns off keyboard backlight

fn+Up arrow = Volume up

fn+Down arrow= Volume down

 

The brightness control hotkeys are fn+Left for higher brightness and fn+Right for lower brightness.

 

I have tried the app called "Shades" but it sometimes makes my screen flash randomly from low brightness to the highest brightness i've ever seen on my laptop.

 

Here is my specs:

 

Acer Aspire M5-581T-6405

Mountain Lion OSX 10.8.2

Processor Name: Intel Core i5-3337U

Graphics Card: Intel HD Graphics 4000

RAM: 6 GB

Display: 15.6" HD widescreen CineCrystal™ LED-backlit display (1366 x 768)

 

P.s. I have another issue with not being able to upgrade from 10.8.2 to 10.8.4

I have the 10.8.4 combo update file and when I install the update I get kernel panics that say:

Kernel Extensions in Backtrace:

com.apple.driver.AppleIntelCPUPowerManagement

 

and then when I reinstalled 10.8.2 again (fresh install) and I update to 10.8.4 from the update file, I am able to boot up in safemode (with -v -x) mousepad everything works, but I am unable to boot up normally?

 

 

Thanks for your help

Touchpad could be kext related and how the keys were mapped. After using the combo update, did you re-patch AppleIntelCPUPowermanagement.kext or use your previous version of the kext? You need to do this for all Apple kexts after each update.

Hi!

I just bump this thread because I have the same problem.

But only for Brightness key (left/right), everything else work.

Is there a way to remap my ApplePS2 kext?

Thanks. :)

Hey OP, could you post a tutorial or directions you followed in order to hackintosh your Aspire M5? I have the same laptop and am interested in doing this.

This thread is probably long dead, but I am also interested in whatever tutorial/directions you may have. I have an acer aspire m5-481. Essentially that same laptop, but with a 14" touch, instead of standard 15". 

 

I would love to hear any advice anyone has on installing mavericks to this laptop (drivers, kexts, etc.)
