izon Posted October 9, 2011 Share Posted October 9, 2011 Finally I got my mac os x 10.6 up and running on my dell n5110 laptop. Everything seems to working fine. The intel hd3000 video graphics card is working, sound is working,recently bought a usb wifi card, and the internet is working. but every time i open a application, the cpu usage just going craze, straight up to 130%. even mouse over the dock, hover some icons, the cpu usage goes up to 60%. the whole process of running application feels lag. what's wrong? by the way, i am using i3 cpu, 6G RAM.I used a lot xcode 4 for programming, and it's not smooth at all running xcode 4. when i am using interface builder, it feels really lag and slowly.
