Like clockwork, MacBook Pro freezes for about 30 seconds every 20-30 minutes... Why?

[QUOTE="pigoo3, post: 1552077, member: 56379"] I'm not sure this is the best approach. Unless I'm misunderstanding things...it seems that the cpu % issues started after the hardware upgrades. Therefore...restoring the computer back to a "hardware state" that was stable is the best thing to do first. This can be a lot easier & faster to do than trying to track down a software issue. What you're trying to do initially is...determine if it is software or hardware. This is easiest to accomplish by doing two things: 1. Reinstall all old hardware (when the computer was stable). - If the problem disappears...then it was a hardware thing (the new ram or the new HD). - If the problem remains...then it's either software or another hardware item. 2. Boot the computer from an external HD with a fresh install of the OS. - If the problem disappears...then it was software issue on the internal HD. - If the problem remains...then it's a hardware item. I would explore the hardware approach first. FYI...I experienced the same CPU % problem a while ago. Turns out it was a defective fan. Not saying your problem is the fan...just an example of how this problem can be hardware related. - Nick [/QUOTE]
