denneboom Posted December 8, 2012 Share Posted December 8, 2012 Hey everybody, I finally installed Lion to my laptop, but now i got some problems. When i go to the system informations, I can see the Radeon HD 6770m and Intel HD3000 under "Graphics". The problem is, Lion uses the Intel HD3000 (with 384MB vram), instead of the 6770m. How can i activate the Radeon HD?. The 2nd problem is, when i insert a usb device into one of the USB3 slots, Lion freezes and crashes. How can i solve these problems?
