gothic860 Posted October 7, 2011 Share Posted October 7, 2011 Hi, im from germany so sry for my (maybe) bad english. I get Lion 10.7.2 to work on my ThinkPad W520 i really hope someone can help me with my DSDT now. I extracted the file from Windows with DSDT-Editor from insanelymac.com. If you need any information about my system just let me know. I tried a lot of things to get it to work and it took me 2 Weeks to get Lion installed so i hope i get a working system at the end with the dsdt . ThinkPad W520 NY424GE - with 16GB Ram - 120GB OCZ Vertex Turbo My CPU- Performance (i7-2720) is the main problem. Under Windows i get around 5,2 in Cinebench and in OS X only 4,2. Maybe a problem with Speedstep or Turboboost? I tried diffrent Benchmarks but nothing changed. If i get it to work i will donate for your hard work!
