There are very few sounds a modern MacBook can make outside of speaker and fan noise that aren’t an indication that something is wrong. If you purchased your MacBook after late 2012, the cooling system is the only part that should make noise.

Startup Tones: RAM Errors and Recovery Mode

If your MacBook repeatedly beeps at you when you turn it on, it’s a sign that something has gone wrong. If you hear either one tone or three tones repeating every five seconds, it indicates that there’s a problem with the system memory. MacBooks feature soldered-in memory, so getting it fixed will require professional Mac repair. If the MacBook makes three long, three short, and three long tones in a repeating pattern, it means something has gone from with the EFI ROM and the computer is in recovery mode. Just leave the MacBook on and it will fix itself in this case.

Audible Fan Noise

MacBook fans tend to run so quietly that you probably won’t notice them in regular use. It is normal, though, to hear fan noise in quiet rooms. However, if you notice the fans start making substantially more noise, it could be an indication of a problem. It is normal for the fans to pick up speed when the computer is executing intense tasks, such as rendering video or performing updates. If you notice the fan noise, put the MacBook on a hard, flat surface, as opposed to leaving it on a soft surface like a bed or a couch, to improve the device’s airflow. If you hear a grinding noise when the fan speed picks up, the MacBook’s cooling system is failing and needs professional repair.

Hard Drive Click of Death

This is an issue for pre-2013 MacBooks that aren’t equipped with a SSD. If your computer is moving really slowly when opening programs or files and is coupled with an audible clicking sound coming from the device, it means your hard drive is nearing failure. This noise is cause for alarm and requires immediate action. The good news is that you have time to back up your data onto an external storage device and replacing the hard drive is a relatively inexpensive fix for a repair service provider.
