k3nny Posted February 9, 2014 Share Posted February 9, 2014 Why do you want it to be 1? As far as I know OS X requires a value of 0. The required change would be: Name (_UID, One) Link to comment Share on other sites More sharing options...

k3nny Posted February 9, 2014 Share Posted February 9, 2014 If you refer to your screenshot, delete line 1740. _UID is already set in line 1731. 1 Link to comment Share on other sites More sharing options...

k3nny Posted February 9, 2014 Share Posted February 9, 2014 Glad it worked. May I ask why you changed it? Link to comment Share on other sites More sharing options...
XLR Posted February 10, 2014 Author Share Posted February 10, 2014 It's for a new GFX card, the old GT210 was working fine on UID=0 but the new GTX650 needs UID=1. I know it can be changed in bootloader configuration but i prefer the DSDT route. Thanks again for the help:) Link to comment Share on other sites More sharing options...
