Himlaklar Posted July 11, 2012 Share Posted July 11, 2012 Hello, Before i start backing up everything, can i upgrade from a working Lion install to Mountain Lion? And does 3 screens work now on ML when using a 670? Link to comment Share on other sites More sharing options...
w3by Posted July 11, 2012 Share Posted July 11, 2012 Not sure about the latter, but yes, you can upgrade from a working Lion to ML. I did it yesterday and everything works great. Link to comment Share on other sites More sharing options...

Thanks for replying! So how do i do that, just run the "install mountain lion" app inside lion? Do i need to re-install chameleon? Link to comment Share on other sites More sharing options...
w3by Posted July 11, 2012 Share Posted July 11, 2012 No idea if it can be done by running the app inside Lion (I didn't see anyone mention installing ML with that, so I didn't wanna risk it). I was following this guide and didn't even have to reinstall Chameleon once I was done (tho I installed a newer version of it anyway), all I had to do once the installation was finished was re-apply two kexts that I already was using on Lion, and that was it. 2 Link to comment Share on other sites More sharing options...
Himlaklar Posted July 13, 2012 Author Share Posted July 13, 2012 Upgrade went fine, no problem at all. Just installed and rebooted, everything working. Except... Still only two of three screens working on my GTX670. Any suggestions? Link to comment Share on other sites More sharing options...
