About This File

--UPDATE MAY 19th--

the project john was working on was cancelled...

--UPDATE APR 29th--

just thought i would share the news here but on this page John has finally got QE/CI working on GMA 4500M, when the driver will be released idk but i will help him make a 64 bit driver of this as i am on mountain lion and i was getting pretty close myself but i couldn't figure it out so maybe with his knowledge of the driver and mine of the 64 bit kext we can finally have a fully supported up-to-date system!


--UPDATE APR 7th---

for those of you who are having problems with brightness on your computer's go here and follow the directions.it worked for me smile.png


--UPDATE SEPT 16th--

been looking at the comments and certain IGP's of GMA 4500 work fine others need fixes (DSDT) to work properly...

Does not work for desktops! :Intel G41 (GMA X4500) in tablets/desktops should work fine and may enable QE/CI

Intel GM45 (GMA 4500MHD) in laptops/tablets work fine need backlight fix

seems not to work for Q chipsets

Intel GS45 (GMA 4500MHD)seems unstable...

Intel GL40 works flawlessly (my chipset wink.png )

working on more info will update shortly wink.png

--UPDATE SEPT 15th--

hello everyone i am back from a long needed vacation smile.png

ok... well back to business

only thing that's different is.. im on windows.... and i haven't had many/any problems :/ guess i was wrong windows 7 is fine

now heres one reason i have windows.. im a gamer and recently lost one of my console's :'(

but ill try to help the best i can ok guys? smile.png and yes if your guessing i highly doubt QE/CI will ever be supported....but we may figure it out wink.png

--UPDATE AUG 2nd--

10.8 does support the 64 bit kexts :cool:


From this point on this page will be used to inform updates,

i have included a READ ME and other things

---UPDATE JULY 10th---

i put in the smbios i forgot to put in *my bad* but otherwise enjoy biggrin.png

---UPDATE JULY 9th---

i included dynamic kexts for your specific device id so u don't have to patch on your own (this took me an hour wink.png )

if u have a unlisted device message me and ill include it, they are in both 32 bit and 64 bit architecture so support for mountain lion

removed a few unnecessary files

---UPDATE JULY 8th---

Quartz Debug settings for performance: QE Enabled,QGL Enabled,BeamSync Disabled/OFF

macbook 4,1 smbios for better performance

voodoopowermini needed for macbook 4,1 smbios speedstep ill include it

plus with VPM you can set p-state limits when on ac/battery/and low battery in the info.plist

---UPDATE JULY 7th---

fixed unmodified kext and updated 2E32 DEV ID kext

---UPDATE JULY 3rd---

updated 32 bit kexts to 6.3.6 made september 2011

included unmodified kext incase someone has a unincluded kext for there dev id (which i could put in if u told me the dev ids wink.png )

less lag and more stable wink.png

no full QE/CI until the non FB kext works or someone makes a new kext (who knows it could be me wink.png )

---UPDATE JULY 1st---

software QE works i use quartz debug ill include it but be warned the CPU has limits!!

added kext for 2E32 device id wink.png

fixed kexts info.plist so theres no need to add dev ids wink.png but still patch them with the bash wink.png

---UPDATE JUNE 28th---

users with 2A42 use 2A42AppleIntelGMAX3100FB.kext if you get this line in verbose boot

IG: Invalid firmware max backlight setting or it don't work first time use GraphicsEnabler in chameleon then if u get both

IG: Invalid firmware max backlight setting

IG: Invalid firmware backlight level setting, your display should work;)

included system info you should know what to do with that wink.png

Mountain lion is 64 bit only and the 64 bit next is kinda buggy so don't expect it to work....maybe try messing around with Chameleon?

I was able to use this kext to get native resolution on my Presario CQ62. All I did was install the kext file though. The readme made it sound like I was suppose to do more than that, but all the pictures in the readme file wouldn't load.

In system information it shows my graphics card as a GMA X3100 instead of a GMA 4500M. Could this be affecting my performance? I can't use launchpad, just freezes up, and I'm afraid to do much else.

if you want better performance you need to have a fast enough CPU to do basic things, 2Ghz should be good enough. if it says somewhere that the CPU is not running at full potential then use a kext to enable SpeedStep

@macos665 your news has changed my life :D , i have just installed mountain lion and the news that for the first time intel gma 4500mhd has qe-ci made very very very happy. i hope you will soon publish a 64 bit kext for qe-ci, so exited :victorious:

Hi, I saw this page from John a couple of days ago too. I'm tripple booting with OS X 10.6.8 and 10.8 then I have Ubuntu for movies:( lol i can not wait to remove ubuntu and be strictly Macintosh.

That being said, how long does testing usually last? how long will it be until we get our hands on this QE/CI kext?????:D Will it improve my OS X 10.8 performance? its a little laggy and makes red blocks when I open the notification bar and launch pad takes long to open:(

Lol it's been almost a month now and I doubt anyone has heard from John. I'm still excited but I must admit my faith is a little bit shaken.

Hi everyone,

Today is a sad day - one of our oldest team members have decided to leave our crew to focus more on IRL.

John have despite being our youngest team member been with us for a long time and he have allways worked dedicated to support and help everyone in hes path - he deserves our respect.

John was also the main researcher behind the QE/CI solution for the GMA 4500MHD - as this was a personal research project he have decided not to share the fruits of hes work - so any questions to this will have to be to john directly.

John, we wish you the best of wishes for a great future and thank you for your hard work and dedication to our course.


bad news !

LOL! load of bullshit, that was a fail. If he got it to work like he said he did, and obviously he was about helping people, why not release the kext with its bugs and hope that someone else like macos665 could improve it. If he did get it to work, he wouldve also known that he got the furthest with the development of a working GMA 4500 kext. Not sharing it at this point is selfish. Sorry if I'm "trolling" or whatever, this is just VERY upsetting

I installed the kext on ML, the resolution worked fine, the problem is the annoying aliasing. What i do to correct the aliasing.
