kyleg40 Posted July 12, 2012 Share Posted July 12, 2012 I am trying to install mountain lion on my desktop. I am running 10.7.4 right now flawless. I did the usb loader 2 times, even have an empty 16gb to test install too. This is what happens, boots, click on the mac install, white screen, apple, then blank..Screen loses connection or restarts...Had both happen I5-760 ASUS P7H55-M PRO Intel i3 i5 H55 1156 Motherboard Geforce 8800 GT 512mb 4gb DDR3 Link to comment Share on other sites More sharing options...

kyleg40 Posted July 12, 2012 Author Share Posted July 12, 2012 I am just not sure what to do with the iopcifamilly modified, where do I put it? On the install flash drive? Link to comment Share on other sites More sharing options...
René_ Posted July 13, 2012 Share Posted July 13, 2012 Just remove "NVDANV50Hal.kext" from the flash drive. It's in /System/Library/Extensions But after installing ML you'll have the same problem. Boot with -x Some 8800GT are giving us problems though it was always a good card. Till DP3 there was no problem. Don't know what Apple did after that?

kyleg40 Posted July 14, 2012 Author Share Posted July 14, 2012 I got tired of trying, went out got a 550Ti card, wouldn't hardly work in 10.7.4, got even more tired, picked up a 430GT and boom, hdmi sound out, video, high def and speed..I am still on 10.7.4 though..I am now afraid to change Link to comment Share on other sites More sharing options...
yonyz Posted July 14, 2012 Share Posted July 14, 2012 You don't have to "change". Make another partition and give ML a try. I can't go back to Lion after I got ML to work. New tabs gesture for Safari (for Magic TrackPad), Notes app, silky-smooth Dock. Oh, and downloads can be canceled via the Downloads dock stack.

Skreel Posted July 14, 2012 Share Posted July 14, 2012 yah, I have the impression all the new OS (ubuntu too) are developed towards EyeCandy Shopping Operating Systems. Guess that's the ZeitGeist sorry for OT Link to comment Share on other sites More sharing options...
yonyz Posted July 14, 2012 Share Posted July 14, 2012 Well eye candy contributes to user experience. We stare at our screens hours a day. They might as well look sleek. Link to comment Share on other sites More sharing options...

Marcel Bidon Posted July 18, 2012 Share Posted July 18, 2012 I am using a Gigabyte Z77-UD5H i7-2600kwith HD6870. It is working ok on Lion. Normally an easy config, it can run with only the bootloader and fakesmc.kext. I prepared the USB according to instructions on the site (including adding my Fakesmc). I booted in verbose mode. All seems to works ok with some warnings (as usual with Lion). The screen turns to white, the arrow of the mouse appears and nothing else except some access to the USB drive. (Mouse is responsive). Probably wait something that is not coming. Any idea? Thanks in advance. Link to comment Share on other sites More sharing options...

Probably wait something that is not coming. Any idea? Thanks in advance. I found a solution: Problem is with graphic card. You should remove ati6000 kext (save it) and replace it by Lion version and put GraphicEnabler to no. After installation you can put it back repare permissions and set GraphicEnabler to Yes Link to comment Share on other sites More sharing options...
