I've found that 5650 responds best to Hoolock or Langur.

10.7.4 screws up our wireless card - use kexts from here to fix @maeras I meant <key>USBBusFix</key> <string>Yes</string> in the org.chameleon.Boot.plist My Plist that works with 10.7.4 <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>AtiConfig</key> <string>Langur</string> <key>EthernetBuiltIn</key> <string>Yes</string> <key>GraphicsEnabler</key> <string>Yes</string> <key>Kernel</key> <string>mach_kernel</string> <key>Kernel Flags</key> <string>darkwake=0</string> <key>Theme</key> <string>LoginToLion</string> <key>Timeout</key> <string>1</string> <key>USBBusFix</key> <string>Yes</string> <key>UseKernelCache</key> <string>Yes</string> </dict> </plist> @ouzo Not sure from your post if you have it working or not? Also, there seems to be a big ugly video smack bang in the middle of it...

Langur made no difference for me... I still think kext works fine, just the display parameters are messed up.

Sounds like a good idea, just hadn't had time to look into it. Will post up relevant bits soon as I can.

I was looking at ioreg explorer last night, and the connected display type shows up as crt. That would mess up a few things... I'll post details when I get home.

I think the display is running in millions of colours correctly because the corruption occurs only on some textures. 3D games are really bad, launchpad too (depending on the wallpaper you use) - but an image open in Chrome will be rendered correctly. It's perplexing. My best guess, the frame buffer isn't a perfect fit and is mangling texture compression.

P.S. If after booting to desktop you have to wait 10-15 minutes for the GUI to become responsive, apply the USB fix in boot.plist.

This is for ATI m5650 models ONLY! A very brief guide on how to get a fully working, craptastic, Acer Aspire 5740G on 10.7.3, in ~10 easy steps. Yeah, Right... 1) Use (aye)Boot to install OSX 2) After installation reboot (via (i)Boot key) and install 10.7.3 combo update. Then use muLt1B3ast for the bare minimum, don't bother with boot loader; just the basics like ps2 support, null cpu power management, rtc fix etc + kext utility 3) Install chimera (attached) 4) Drag the kexts from the "needed kexts" folder in the attachment onto kext utility. 5) Copy attached boot.plist and smbios.plist to /Extra 6) Sort out your EDID override following instructions here. Or... you can try my EDID "717" file. If you do, I take no responsibility for cats having sex with dogs, outbreaks of rage virus in the neighbourhood or exploding computers. Having said that, my edid has worked on at least a couple of 5740Gs. YMMV. 7) Go to screen sharing and enable VNC. There's a good chance you will get a blue/black/garbage screen on first reboot and you will need to VNC in and set a sane resolution (from 1900x1200 in my case - yeah, I wish...). Obviously, if you are using wifi, now is the time to make sure your lappy logs into preferred networks automatically - setting DHCP manually can make your life easier if you are on a big network that cycles IPs often. 8) You may want to fix permissions, sacrifice a chicken, whatever hoodoo makes you feel better before doing something that requires a bit of luck. 9)Shutdown and... 10)Boot back into your hacky... Boots but screen is awol? VNC into your machine and set things right. 11) 10.7.4 update screws up wireless, in addition to replacing the other kexts also need ones from here. http://www.osx86.net/view/2311-ar5b195_-_ar9002wb_pcie_wireless-half_size.html Have Fun... Sleep is very patchy btw... sometimes it works, sometimes...well... -f -x -v then shutdown and restart. PS. My laptop is a BT free model, I use a dell mPCIE card in the second expansion slot so my bluetooth instructions are of no help here. If anyone has ones for standard acer cards let me know. ok... I've been a way from hackies for a while - what's with ####### on this forum? Use your imagination for a bit of phonetic spelling. Acer5740G.zip

A simple way to get hex converted to text is to use the hexdump command. For example; hexdump -v -e '1/1 " %02X"' ~/Desktop/EDID-OUT > ~/Desktop/EDID.TXT Will dump it as EDID.TXT from the EDID-OUT I placed on my desktop. Everything I learned about hexdump I learned from man hexdump and here.

Look, good luck -really, I made many a DSDT in my time and they are a PITA. However, when you get it right it's brilliant - my Dell 620 dsdt gave me a full vanilla install with everything working 100%. But, I doubt you will get around the fact that the ATI 5xxx drivers included in OSX are for a wrong type of display architecture, before you patch the DSDT you will need to find a way to make them work with old fashioned LVDS displays. Perhaps there's a way to make them work properly with our external HDMI/VGA displays and just give up on the internal display, that seems doable... Best of luck.

If you read the thread you posted in you will find your answer. It seems like people are asking the same questions over and over in this thread. RTFM guys, they've all been answered before. Warning about running media bay drives, you can end up with terminally borked partitions if you run OSX (or other *nix) on them. Especially the sata ones. I've had my D620 replaced by another laptop, so I'm out. of here. Good luck and goodbye...

That is the internal connection that our displays use, it's an old school way of hooking up LCD panels in laptops. Apple laptops are now all display port, and so are the Apple 5xxx drivers. As far as I know there's almost 0 chance of there being a viable apple driver for our laptops due to this. Sorry, it sucks, I know.

Yes, use graphics plist string and patched DSDT.aml . People struggling with multi boot, can I redirect you to this POST Detailed information on how to do both things is either in this thread, or found if you search this board and the intertubes...

Attached are the two I use, it will also give you full PCI info in system profiler. Of course, if the card you are trying to use has no OSX drivers, it won't work. Firewire, usb cards work well, my esata has to be plugged in at boot to work. WWAN only work if you have drivers from manufacturer - In my experience anyway. PCMCIA.zip
