Introduction

It seems like there aren't many guides out there for peeps with an Acer Aspire 4750G laptop, so here, with time to spare 'cause my final exams are over and graduation draws near (pa petiks-petiks na lang), I made a guide. It is also my solemn responsibility to keep this guide updated as much as possible and user feedback is highly appreciated. Questions are entertained but please, use also your common sense, its for your own good too. Anyways, my laptop specs as follows:

- i5-2410M
- Intel HD3000
- GeForce GT 540M 2GB
- 2GB DDR3 1333Mhz (expanded mine to 4GB DDR3 1333Mhz, Tanya + Kingston)
- AR5B97 Wireless Network Adapter
- Netlink BCM57780 NetLink Gigabit Ethernet
- Cougar Point High Definition Audio Controller
- NEC uPD720200 USB 3.0 Host Controller


Prerequisite

1 8GB USB thumb drive or flash drive
Mac OS X Lion Application or OS X Lion USB Thumb Drive
An existing MAC or Hackintosh
And a lot of patience and humility


Installation, for the installation guide just follow tonymacx86's UniBeast Method.

NOTE 1: Don't follow Tonymacx86's guide about partitioning/preparing your computer's hard drive for OS X Lion installation because the BIOS in Acer is based on UEFI, a laptop BIOS firmware that doesn't support the GUID partition table so MBR must be used in this guide.

NOTE 2: Better make sure you ticked "Laptop Support" or else the USB wont be bootable.

If you're done making the bootable USB, replace the needed packages with the patched ones you downloaded so dual-booting and installation on a MBR partition table is possible. After doing those, restart, at POST press 12 and choose your boot device, the one that you just made. Then at the Chimera screen, choose the drive whatever you named.

By now you'd be impended by the "before we begin" screen that prompts you that your keyboard is not detected. In that case, then there are two options to do, buy a cheap USB keyboard or follow this shi**y guide I found on other forums.

Reboot into the Lion partition again but with the arguments -x (for safe mode) and -s (single-user mode for privileges, rights, etc) and navigate to /System/Library/CoreServices/Setup\ Assistant.app/Contents, open the file info.plist and delete the following lines from it.

Code:
<string>DeviceSection</string>
<string>KeyboardTypeSection</string>

Reboot, problem is gone and you are now free to create a user for your new hackintosh. So enter a username, password, user picture (don't use the webcam yet or else your computer will hang) and so on.


Post-installation tuning, use the latest MultiBeast available.

There are the necessary drivers that should be installed prior to the installation of OS X Lion on an Acer 4750G. Double check if you ticked the following before moving on to the next step.

>>Repair Permissions

>Drivers and Bootloaders
>>Kexts and Enablers

Download Andre.ncs's Kext pack for Acer 5750G HERE. Yes I know, it's for 5750G but we're only after for the IO80211family.kext and VoodooHDA.kext, so just install them both with your preferred kext installer.

Download the GenericBrightness.kext attached here and install with preferred kext installer.
Download the SleepEnabler.kext attached here and install with preferred kext installer.

Then after installing those, run MultiBeast again and tick "extension migration tool" at the bottom, this is for the purpose of using kernel cache. And lastly, close MultiBeast, launch it again, tick repair permission and reboot.


Conclusion and Summary of Findings

If everything goes smoothly, congrats! You now have bragging rights and should have the following in working order too.

1. Trackpad - Gestures
2. Keyboard - Full mapping
3. BRIGHTNESS - Resets on startup but adjustable anywhere. Use Fn + directional buttons in adjusting the brightness.
4. WIFI - Doesn't auto-connect.
5. SLEEP (works with SleepEnabler.kext) - BE PATIENT!
6. USB3
7. Ethernet
8. Sound
9. KernelCache
10. Battery
11. CPU power management
12. CPU Turbo Boost feature
13. Full graphics acceleration (QE/CI)

Not working so far...

1. AR5BBU12 Bluetooth module
2. nVIDIA GeForce 540m - Detected and memory allocation is right but doesn't work :banghead:
3. HDMI - haven't tested this out yet.

Not Working

1. VGA - ...

I use the on-board intel hd graphics for mac because the nvidia card isn't supported yet. In my bios settings I have the video type set to switchable since I barely use OS X but even if its set to that, OS X doesn't seem to have any problems If I boot it up.

For the trackpad, it has multi-gestures but I don't know about the launchpad thing since I use the function key shortcuts (similar to a real mac).

I haven't updated to 10.7.3 because of slow net speed :banghead: but im on 10.7.2. I just backed everything (the kext used) up, installed the combo update (10.7.2) and installed everything back again.

Kernel panics went away when Tonymac made a public announcement for the usage of usekernelcache. Didn't know if its disabled, its like using -f agrument.
 
Hey thanks for replying! Oh I see. So the lion using the intel hd graphics instead of nvidia right? Does it support qe/cl? How do I test it if it's working? And about the kexts pack? What kexts did you install and how did you install it? I do not know how to install the kext utility that comes with the multibeast 4.2.1. Well thanks for replying :)
 
Yeah. Intel HD Graphics works out of the box once you install OS X Lion. And yes, it supports QE/CL, you dont really need to test it it's working, you'll know its working when the menu bar is transparent :D

About the kext, just use the IO80211Family.kext to enable wifi.. dunno if this will work on ur wifi card though.. check under ur laptop if there's an Atheros sticker.. make sure its AR5B97 or AR9287.

Installing kext is easy.. just go to the applications folder > utilities > there you'll see Kext Utility, click it and it'll ask for password, then just drag and drop the necessary kext you need to install. Or you could just search for kext utility in spotlight and just follow the next step.
 
Oh yeah buddy. The graphics has qe/cl. I have the transparent menu bar. But I don't have the ripple effect in dashboard. Or is it for SL only? About the kexts, yup I figured it out. I installed all the kexts. It seems all are working. Even the brightness and the battery and wifi. I have the AR5B97. It seems perfect! But I have another issue. The sleep and trackpad scroll. I don't have two finger scroll. I have 10.7.3 btw. And another thing, I would like to show on my desktop the usb drives. Like when I plug in my usb the usb drive will show up on my desktop. Its very PIA when I go to finder and open my usb drive there. Hey thanks again!

Edit: oh yeah btw do I need to select the 64 bit graphicsenable=no? This is one out of many questions I have lol!
 
The ripple effect in OS X Lion is currently disabled by default. If you want to bring it back, just click HERE.

IDK about he two finger scroll since I just use same way of scrolling.. slide my finger on the right most edge on the trackpad. and the bottommost side.

USB drives, externals, etc can be displayed in the desktop by follwing this GUIDE.

Haha you I just deleted graphicsenabler=yes in my chameleon.boot.plist thing.. but added it back since it screwed the info in "about mac" .. without it, the sytem identifies the GeForce 540m but leaves the Intel hd graphics "unknown" anyways should be a problem :D but dont add it anyway..
 
Ahhhhh iat first I thought I'm missing out QE/CL cause there's no ripple effect. On my previous mac SL there's a ripple effect.

Oh how did you it? What kext did you use for the trackpad? I found some kexts for synaptics from another website but it just gives my 2 horizontal scrolling lol! No 2 finger scroll nor scrolling in the edge. nevermind :) i just used the new Multibeast 4.3 and installed the ps/2controller. it work! scrolling the edge and 2 finger scroll works! just a tiny complain is that scrolling is inverted. i mean if i scroll down it scrolls up and vice versa. any fix here?

and btw is sleep possible? i have a kext here but i'm not sure if it's working or not. can't risk installing now because i need my laptop for school presentation (and to show off lol!!)

almost there! thank you so much!
 
Scrolling is inverted by default. If you want to revert it back to the old direction, read THIS.

IRDK about sleep, I tried it before, it worked and managed to wake my laptop from randomly smashing keys but the second time I did it, it no longer worked... I dunno why. Anyways, I don't use sleep nor use the hackintosh itself, just for bragging rights so good luck with ur showing off tomorrow (or yesterday, haha timezones).
 
Wow thanks again! I never thought it will go this far. Lol! Well I only need when I'm in school. Transferring room to room. It's so hard here in the philippines you know lol! Anyway thanks again buddy! I'm only interested in hackintoshing cause can't afford the real one :( but maybe in the near future.
