I have a mid-2009 13" core 2 Duo MacBook Pro running High Sierra w/ upgraded 8 Gb RAM. On Activity Monitor I usually get 20-40% 'idle CPU' with only Finder, Safari (3 tabs) and Activity Monitor opened. There's also nothing plugged in. 'User CPU' load varies quite a lot, but never above 'System CPU' which is always around 50%. So I wonder if those are normal CPU loads for my mac. high CPU load My mac always feels kind of hot despite having just these 3 apps opened and using it on a flat, wooden surface, slightly below room temperature with no direct sunlight. I read that it could be an issue with the cooling system, but the fan seems to work fine and I already took some dust off inside my mac (without detaching/disassembling anything except the metal case; maybe I should clean some parts separately?). Apple Hardware Test also gave me nothing on a simple test. Thank you to anyone who might respond.
