Steven Poon Posted March 26, 2013 Share Posted March 26, 2013 Hi I have successfully install Mountain Lion 10.8.3 on my x220, at least all basic things are function... however... I can only boot using the USB drive (the installer), select my HDD than can boot, else it will display menu for me to choose which HDD to boot up, no error message. I tried install Chameleon but still same, I am using the GUID table during installing the OSX. The HDD only have single partition. Please assist and help... I dont wish to carry the USB drive just for the sake of booting the laptop... Link to comment Share on other sites More sharing options...

Administrators Hervé Posted April 2, 2013 Administrators Share Posted April 2, 2013 Would you mind sharing how you did it (the serial number)? Did you just manually modify the SMBIOS plist? Link to comment Share on other sites More sharing options...
