I have a IBM/Lenovo ThinkPad T60 195x (bought at the end of year 2006). I installed Mac 10.6.3 Retail and combo update to 10.6.6 okay ! Most of devices work good (except wireless). However I have a problem with laptop 's monitor. After startup, laptop monitor show up a white+gray screen, I can not work with it. But if I connect with external monitor (ViewSonic), the Mac screen is okay and I can work with it. Please tell me how to fix it ? Show up with laptop 's monitor ? Thanks so much !
