Chosen Solution
I recently upgraded my MacBook Pro to MacOS Sierra. After the update, my Mac started making clicking noises. It is a repetitive noise every 5 seconds or so. Edit: Corrected to MacOS Sierra The computer works perfectly from what I can tell. There are no software issues. After the upgrade, I restarted my computer and noticed the noise. The noise is like a clicking/tapping noise, 12 times in a portion of a second, and it repeats every 4 seconds. I have not made any other changes to my MacBook.
I suspect you have some junk wedged in the fan or the fans bearings are starting to fail. At this point I think the best thing here is to open the bottom cover and using a small paint brush carefully scrub the fan blades and a few short blasts of can’ed air to blow the dust and junk away. Don’t forget to clean the vent area as well. Did that solve your problem?
Do you mean macOS 10.12? iOS is for iPad’s, iPhone’s, or iPods, not MacBooks.
Since you just installed a new HDD I’d suspect that, although I’d need to hear it to know for sure, (unless you upgraded to an SSD which should not produce any perceivable sound at all.)
Does this MacBook Pro have a HDD (spinning hard drive) or a SSD (solid state)? Thanks.
Omg this is what to do if you have like a table fan or something take your laptop and hold your computer in front of the fan and it will blow the dust but first use a q-tip to clean the vent area
My MBpro Oct-2014 has an SSD and I noticed the same issue, especially when a computation starts on matlab or when I start a movie… but it does it also when still and idle (less often). The sound is exactly the click that you hear due to the “hard disk initializing “ (classic sound I heard on my old laptop when turning on, a couple of clicks before the speed goes up) but obviously it can’t be that: apart from the fan, everything here is solid state without moving parts. I have two guesses: thermal expansion due to the processor instantaneously warming up (and my sensor having some delay? I monitored it without noticing anything strange) or wrong pwm signal to the fan, that glitches sometimes and stops it in micro-periods. The second hypothesis looks more real, but I don’t know why I started noticing it since Sierra.
hi all ,my solution to the click issue (not solved completely) is to run first aid on my Main SSD (eg with the OS on it )then turn off and on again,this will stop the clicking from usb sound output for about a week of being on all day,this is on a mac mini i5, first aid on the other Normal HD dosent stop the clicks . I fitted a Main SSD on my previous mac mini duo core and had exactly the same issue.
