Hi everybody, I updated to El capitan (macbook pro early 2008) and I have a big problem. Every 10 min my os freeze for just 5 second... I can't use mouse or keyboard but the system still working (for example videos or loading wheel)... It's really annoying! I have a ssd hd + 1tb hd. I already made a clean install of the OS. Can someone help me please? thanks a lot F.
