I have installed OS X 10.7.3 on my Toshiba Satellite L555-10M

For the Graphics i used the Kext's from Smartie77 http://www.insanelymac.com/forum/topic/274833-ati-4650mobility-lvds-shrike-for-lion-1073-final/

But in the Settings i can only choose 1366x768 (my resolution is 1600x900) and the screen colors get crazy so that i cant see anything.

 

Hope anyone can help me to get a solution for that

For more than 1366x768 resolution you have to do forced display edid. Can follow one of the following guide -

Try using graphics flag GraphicsEnabler=No or delete GraphicsEnabler flag from boot.plist.

 

 

More than this if you have interest can use my kexts from - http://www.insanelymac.com/forum/files/download/41-ati-mobility-radeon-hd-550v46501002-9480/

Update up to 10.7.5 (11G63) and install my kexts. Before update remember to delete ATY_Init.kext & voodooHDA.kext if you are using, I mean kexts which can cause KP must delete.

 

Thanks

If all are same, would like to play with latest version :P . Update up to 10.8.4, install kexts from - http://www.insanelymac.com/forum/files/file/86-ati-mobility-radeon-hd-550v46501002-9480-os-x-108412e55/ . Boot with -v GraphicsEnabler=No. Let me know ....

 

Go to windows make a vga bios dump using AIDA64 soft. or others. Send.

It is not possible, First it had show the display as "Toshiba Internal Display". So you might do something wrong, manually paste it again & repair permission. Feedback again.

Send me also your org.chameleon.boot.plist file.

 

Edit: ATI4600Controller.kext not loaded, delete the kexts & install them again. Boot with -v -f GraphicsEnabler=No.

Hope fully looking good :D . If you start with external display connected, you will get internal display black. With this kexts you can use only internal display or external display.

 

Wants all ok ? go to - http://www.insanelymac.com/forum/files/file/86-ati-mobility-radeon-hd-550v46501002-9480-os-x-108412e55/ . Download kexts, delete only two required kexts from S/L/E, install downloaded kexts. Hope will find all things, fine !!!

 

Good Luck

All things are on your hand. Now do it your self :P . Repair permission and boot with -v -f flag, thing some how kexts not loading.

Don't connect external display, you may able to use internal display with previous setup with - Kexts.zip

 

Try hope will find the way :D .
