I am having an MacBook Pro7,1 (13-inch, Mid 2010), running OS X 10.8.3,  and lately it started to make disturbing noise.. Its something like short "beep", and the first time I noticed it was when the fan was working really hard, the noice was comming in intervals of one-one and a half minute. That time I thought it's something connected with the fan and just turned the laptop off. Repaired permissions + cleaned the cache with Mountain Lion Cleaner.

Yesterday though I heard this "bleup" sound again, but this time the fan was not working. The noice is not constant, it starts out of nowhere and I cant notice any pattern in it, like if the laptop was working for too long for ex., sometimes it starts 10min after i switch the MacBook on.


Tried to do the Apple Hardware Test (without the cds), but it seems that I cant do that neither - when connected over internet it says its not available for my computer. In order to run the AHT, tried to update manually the EFI and SMC firmware updates as I read is an option for the model I have, but it says "this software is not supported on your system".


If you have any thought and advices on any of those topics, please share!

    I recommend you take the MBP to an Apple store. Diagnosis is free, and they, unlike us here, will be able to hear the noises.


    By the way, what is Mountain Lion Cleaner ? Are you sure it is safe?

    A 2010 MBP came with installation disks.  Did you try the Apple Hardware test with them?

    It is my understanding that it should, but the facts as you report them, it does not, ergo I suggest you locate the disk with the Apple Hardware Test.

    Aside of all help here, I strongly suggest that you get rid of all antimalware, antivirus, boosters, optimizers, cleaners and such apps. Nothing but trouble.

    Thus get rid of Mountain Lion Cleaner (a "new" star on the firmament).

    The caches in OSX are taken care of by the OS itself: daily, weekly, monthly. Cleaning is not necessary, and it will slow down your computer because they are being filled again.

    Beeps are an indication of hardware problems.

    Fans running high are an indication of temperature rising because of runaway apps.

    Thus follow the advice to have Apple diagnose it, even if it costs a few SK.

    The fans: run Activity monitor, click the %CPU Column, until the highest % is on top. Look wich processes are using the highest %.

    I live in Toronto, Canada. I can make an appointment at a genius bar and take my mac in for someone there to look at what might be wrong. This is free. I once spent about half an hour with an Apple employee, diagnosing my daughter's 3 year old Macbook. No cost.
