Nekcbraker Posted August 18, 2012 Share Posted August 18, 2012 Hello, I'm tring to update my Lion machine to Mountain Lion. I've purchased the app in the App store and prepared a USB stick. I can boot it, no problem, but in the Installation process, I'm not able to just update my Lion Installation, the Installer tells me, i have to partition my HDD before i can Install. What am i missing, or doing wrong? Thx for your help Link to comment Share on other sites More sharing options...
HUSABER Posted August 18, 2012 Share Posted August 18, 2012 Your Lion is install on MBR or GUID partition? If is install on MBR you need this patch for ML: http://www.osx86.net/view/2902-os_x_mountain_lion_gm_mbr_patch.html 1 Link to comment Share on other sites More sharing options...
