[GUIDE] Install Lion on Acer Aspire 4750g

2 posts in this topic

Recommended Posts

Ciao, this tutorial is written after months of failed installations (at least 20) and testing which probably wrecked my laptop by now. The following applies for the Acer Aspire 4750g, a notebook which is really a pain in the ass. However, if other notebooks also have an Intel Core i7 (with sandy bridge Intel HD 3000 integrated graphics) or an Nvidia GT 540M (this card is NOT supported, but detected by Lion), one can also follow some points from this guide to achieve full QE/CI. Of course, credit goes out to tonymac, netkas, etc. who have come up with great utilities and kexts, as well as the Chinese language Acer forums which I ripped the kexts from. :angel_not: Hope that others with the same pain-in-the-ass laptop can stop worrying now. http://yfrog.com/odzygepj


Here are the specifications of this model and what is working and what is not:

  • CPU and chipset - Intel® Core™ i7-2630QM - WORKING without DSDT needed, integrated Intel HD 3000 FULLY WORKING
  • Display - 14" HD 1366 x 768 - WORKING at full resolution
  • Graphics - NVIDIA® GeForce® GT 540M with NVIDIA® Optimus™ technology - NOT SUPPORTED as mentioned above, but integrated graphics WORKING. Disable NVIDIA card in BIOS if possible
  • Audio - no idea - WORKING
  • Webcam - NOT WORKING
  • Wireless - Atheros AR9287 - NOT WORKING for me (BUT other forums reports working with kext+fix, haven't tried fix)
  • Keyboard and touchpad - WORKING
  • USB - Not all ports work, USB 3.0 SHOULD WORK with kext

And here is what you need:

  • 8GB USB drive or larger
  • Lion installer dmg (from Mac App Store) or Lion installer thumbdrive (from Apple)
  • [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] (as of this tutorial v4.2)
  • Chimera (as of this tutorial v1.7)
  • Bag of kexts - links are below!
  • [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url]

1. Download [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] and follow its instructions to create an installer thumbdrive - http://tonymacx86.blogspot.com/2011/10/[url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url]-install-mac-os-x-lion-using.html

2. Copy the following packages onto the thumbdrive (in an empty folder) -

  • Chimera (bootloader)
  • VoodooHDA (to enable sound)
  • Your favourite kext installer
  • OR [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] (in place of the three options above)
  • IOUSBFamily.kext and IOUSBMassStorage.kext (to enable USB) - http://www.osx86.net/view/2065-iousbfamily.kext_for_non_working_usb-s..html
  • Networking kexts (optional, might not work)
  • VoodooBattery.kext (optional)

TIP! - If you need to install it on an MBR partition, use the patcher - http://3rr0rists.net/driver/mbr-patch-for-lion-gm.html ([url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] cannot install to MBR, only GUID which didn't work for me due to bootloader reasons)


3. Install Lion (simple, not a lot of options) - Partition with GUID unless patched, I suggest patching and using MBR.

4. Reboot and boot new installation using [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] thumbdrive, in single-user mode (-v -s)

5. Mount the root partition in read-write mode (instructions in terminal)

6. 'cd' to /System/Library/CoreServices/"Setup Assistant.app"/Contents, edit Info.plist and delete the lines with keyboard selection and device selection (sudo pico, or copy over with a patched Info.plist floating somewhere from the internet)

7. Exit and finish setup assistant.

8. Copy the folder full of kexts from the [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] thumbdrive to the desktop.

9. Run Chimera pkg and VoodooHDA pkg


10. Run [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url], selecting Chimera and VoodooHDA ONLY.

11. Reboot (although you would most likely get kernel panic) using [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] thumbdrive back into new installation.

12. Using the terminal, copy the following files:


sudo -s
mkdir /Extra/Extensions
cp -rf /Volumes/([url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url])/Extra/Extensions  /Extra
cp /Volumes/([url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url])/Extra/org.chameleon.Boot.plist  /Extra
cp /Volumes/([url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url])/Extra/smbios.plist  /Extra



13. Go to /Extra/Extensions, and delete IOUSBFamily.kext and IOUSBMassStorage.kext

14. Copy the proper IOUSBFamily.kext and IOUSBMassStorage.kext which you downloaded to /Extra/Extensions

15. Run the following in Terminal


sudo chmod -R 755 /extra/extensions/IOUSBFamily.kext
sudo chown -R root:wheel /extra/extensions/IOUSBFamily.kext


16. Run Kext Utility OR fix permissions, rebuild cache with your favourite utility. Install VoodooBattery (optional)

17. Reboot without [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] thumbdrive in verbose mode.


That's it! ^_^


If network is desired, kexts (http://www.osx86.net/downloads.php?do=file&id=1626) and link for fix (http://bbs.pcbeta.com/viewthread-882193-1-1.html second post) is here. Any file one requires, I can upload upon request!


This is my first Hackintosh guide, so please forgive and point out mistakes. Grazie..
