myska Posted November 22, 2011 Share Posted November 22, 2011 Hi, I need to disable nvidia optimus as my graphics card GT 525M is not recognized by Lion and causes freezes in 10.7.2 every 5 seconds everytime I try to load any app. Sadly, I don't have any disabling function in my dsdt to edit it as shown in this topic: http://www.insanelymac.com/forum/index.php?showtopic=271292. Could you help me to add this patch or send a dsdt already edited this way? Thanks in advance. dsdt.rar Quote Link to comment Share on other sites More sharing options...
