hinmatth Posted March 14, 2012 Share Posted March 14, 2012 Hello everyone, I am new to this forum and Mac! Let me introduce myself! I come from Hong Kong and I am a 15-year-old boy. I am interested in programming and installing some new softwares or operating systems Yesterday, I followed the instructions in a post and installed a new mac on my pc successfully But, I realised that I can't boot normally and I must use '-x -v' to boot. If I use '-x' only, it shows a screen with black and white crappy blocks. I checked the resolution and I found that the resolution is in '1024x768'. I found many solutions to install the kext on my mac but none of them could help me. After I installed the kext and I booted, the monitor said that the video mode is not supported and told me that to reset the screen resolution to '1680x1050@60Hz' My monitor is Philip 220WS8FS Here are my specs: MB: Asus P5Q CPU: Intel Core 2 Duo E7400 RAM: Samsung ??? 2x2GB Display card: Sapphire ATI Radeon HD 4850 HDD: Seagate 500GB Can someone help me to solve this? Thanks for your help! Link to comment Share on other sites More sharing options...
buoo Posted March 14, 2012 Share Posted March 14, 2012 Drag ATI4800Controller.kext from System/Library/Extensions to the Desktop, then Show Packages Contents and open info.plist file with a text editor and add your deviceID 0x94421002 Save the file and install the new patched ATI4800Controller.kext with Kext wizard or Terminal, rebuild the kextcache and reboot. i.e. <key>IOName</key> <string>ATI4800Controller</string> <key>IOPCIMatch</key> <string>0x94421002 0x94401002 0x944a1002 0x944c1002 0x944e1002 0x94411002 0x94431002 0x94601002</string> <key>IOProbeScore</key> <integer>65000</integer> <key>IOProviderClass</key> <string>IOPCIDevice</string> </dict> </dict> good luck Link to comment Share on other sites More sharing options...

hinmatth Posted March 15, 2012 Author Share Posted March 15, 2012 (edited) Thanks for your reply! I have done the things above... I have rebooted normally and it stucks at the light grey screen again. Then, I've booted with '-v' and it stucks at the screen with white and black crappy blocks Finally, I've booted with '-x -v' and I can log in to the mac successfully. So, what's the problem? Thanks a lot Edited March 15, 2012 by Gringo Vermelho Don't quote entire posts when replying directly below them. Link to comment Share on other sites More sharing options...
