xinzhouliu Posted June 15, 2013 Share Posted June 15, 2013 Hello, I'm trying to install Mountain Lion on my XT2 (Core 2Duo, 5 GB RAM, 130 GB SSD). I tried many ways, all failed. Please help. Link to comment Share on other sites More sharing options...
Darvinko Posted June 15, 2013 Share Posted June 15, 2013 That usually comes with the GMA 4500MHD graphics cards which won't support acceleration in Mountain Lion currently, making for a less than enjoyable experience. Double check to see if you have different graphics (on boot up, tap f2 key to get into BIOS and scroll down to Video Controller section and take note of which is in your machine).

xinzhouliu Posted June 17, 2013 Author Share Posted June 17, 2013 That is correct, the graphics card is GMA 4500 MHD. The strange thing is that I can't even install the system... I never got to the installation screen with choosing languages etc... Pls help. Link to comment Share on other sites More sharing options...
Administrators Hervé Posted June 17, 2013 Administrators Share Posted June 17, 2013 Hi, Can you try to boot with -v option (for verbose) and tell us what you get (error message, last message before it possibly hangs, that kind of thing)? Link to comment Share on other sites More sharing options...
Administrators Bronxteck Posted June 17, 2013 Administrators Share Posted June 17, 2013 ahcidisk=1 debug=8 dart=0 -v -f try the flag as posted Link to comment Share on other sites More sharing options...
xinzhouliu Posted June 17, 2013 Author Share Posted June 17, 2013 Herve - I tried -v (and some other flags), it goes to the white/grey screen with the spinning wheel, and then it hangs while the wheel keeps spinning. If I try something with PCI or so, then it hangs at PCI configuration... Bronxtech - I will try your suggestion. Link to comment Share on other sites More sharing options...
Administrators Hervé Posted June 17, 2013 Administrators Share Posted June 17, 2013 Mmm, -v should give you lots of text until the very last moment where OS X goes to Desktop display. Try: -f -v GraphicsEnabler=No Link to comment Share on other sites More sharing options...
