Optical Drive
-
One potential cause of a loud buzzing noise coming from your MacBook is the computer's optical drive, according to Apple. The optical drive is the slot-loading drive into which you insert CDs and DVDs. The optical drive may buzz not only when you have a disc inserted into it, but also when you wake a "sleeping" computer up. A buzzing optical drive is nothing to worry about unless the optical drive stops working.
Hard Drive
-
A more potential serious buzzing can come from the MacBook's hard drive, which is located on the left side of the computer's trackpad. If you hear a loud buzzing noise coming from the computer aren't able to determine where it's coming from, place your ear onto this portion of the computer and try to hear if the noise is coming from the hard drive. If it is -- and it may be accompanied by clicking -- this can indicate a potential future hard drive crash.

Speakers
-
Another component of the MacBook that may produce a loud buzzing noise is the computer's built-in speakers. This can occur unexpectedly or in some cases, if a call comes in on your cellphone and the cellphone is near your speakers. If the buzzing sound doesn't disrupt your music listening experience, it isn't absolutely necessary to seek repair.
Seeking Repair
-
You should seek repair if you notice hardware or feature malfunctions accompany the buzzing noises. If the MacBook is under warranty and hasn't fallen victim to any accidental trauma, it is likely that any repairs that need to be made will be covered by the warranty. Take the MacBook Pro to a nearby Apple store or contact an Apple representative at 800-275-2273 to learn about other repair options.
