SD223 Posted February 14, 2012 Share Posted February 14, 2012 Hello, Id like to say thanks inadvance for the responses. I am running lion, and I changed the string in /extra/com.apple.bios.plist to one given to me by a program. I was trying to get my apple store to work. After restarting however the I am able to see the grey apple logo and the gear. Once the computer is in OSX before I can see anything the GPU turns display to the monitor. I have tried '-x "Graphics Mode"="1280x1024x32@85" platform=ACPI or platform=X86PC', GraphicsEnabler=No but still having no luck in getting in to reset my com.apple file. If there is a way to restore it, I have been keeping a recovery drive. I just can't get to it outside of OSX. My gpu is a GTX260 on a EVGA x58 Please any help would be greatly appreciated. Let me know as well if you need additional information. Link to comment Share on other sites More sharing options...

SD223 Posted February 14, 2012 Author Share Posted February 14, 2012 Thanks for the quick response, soln 1 didn't work so i proceeded to solution 2. But when i try to edit using Nano /Extra/com.apple.Boot.plist or /Library/Preferences/SystemConfiguration/com.apple.Boot.plist I can't save it. i think I am a single user since it hasn't asked me to enter my password. Right now Im trying to use the backup i had saved to desktop but even that one won't save when I edit it. Thanks sorry my bach isn't that great. Any help with this much appreciated. even with sudo nano /Extra/com.apple.Boot.plist I get the error: Read-only file system unable to change permissions using sudo chmod 555 followed by file name.

LatinMcG Posted February 15, 2012 Share Posted February 15, 2012 did u mount / read write ? try changing directory or attributes of file or rename it and boot from cd or usb and fix it try chown or chmod command to take permission of /Extra Link to comment Share on other sites More sharing options...
