MacBook beeping 3 times at startup? Here's why and how to fix it
⚡ Fast fix
- Shut it down and try again: Hold the power button for 10 seconds, then turn it back on.
- Unplug everything: USB hubs, drives, monitors—start it with nothing connected.
- Check your charger: Try a different outlet or cable to rule out power issues.
- Reset system memory: On Intel Macs, restart and hold Option + Command + P + R for ~20 seconds. On newer Macs, just restart.
You start up your MacBook expecting to hear that familiar start-up chime… except it doesn’t happen. Instead, you get a series of beeps. Your MacBook is making beeping noises and not turning on. What can you do? Don’t panic—we’ve got you covered.
At Asurion, we know tech and can help with everything from repairing your MacBook® to walking you through how to add more memory. Here’s what you need to know about why your MacBook Pro® is beeping three times and how you can get it working as it should again.
What does 3 beeps on a MacBook mean?
Most of the time, three beeps at startup are tied to a memory issue. That could mean:
- Your Mac isn’t detecting memory properly
- There’s a temporary glitch during startup
- Or there’s a deeper hardware problem
On older Intel Macs, memory (RAM) could sometimes be adjusted or replaced. On newer Apple Silicon models, it’s built in—so there’s less you can do on your own.
If your Mac also won’t fully power on, this guide on what to do when your MacBook won’t turn on can help you rule out other causes.

How can I fix the MacBook three-beep problem?
Before assuming the worst, there are a few safe things you can try at home.
Restart your Mac
It sounds simple, but it’s often the fix. Shut it down completely, wait a few seconds, then turn it back on. If it was a temporary hiccup, this can clear it.
Disconnect accessories
External devices can sometimes interfere with startup. Unplug everything—USB hubs, drives, monitors—and try powering it on again with just the charger connected.
Double-check power
If your Mac isn’t getting steady power, it can fail startup checks. Try a different outlet, cable, or charger if you have one available.
Reset system settings
On Intel Macs, resetting NVRAM can help clear startup issues.
Restart and hold Option + Command + P + R for about 20 seconds.
On Apple silicon Macs, this happens automatically when you restart—so no extra steps needed.
What not to do
When your Mac isn’t working, it’s tempting to try everything you can find online. A few things to avoid:
- Opening the Mac to “check the RAM”
- Repeatedly forcing it to restart over and over
- Downloading unofficial tools or firmware fixes
If you’re not careful, you can easily make things worse.
When it’s probably not a quick fix
If you’ve tried the basics and you’re still hearing three beeps, it’s likely not something software-related.
In many cases, that means:
- A memory-related failure
- A logic board issue
- Or another internal hardware problem
At that point, more troubleshooting usually won’t help.
If you've tried these steps and still need a little help, we're right around the corner. Schedule a repair at the nearest uBreakiFix® by Asurion store and our certified experts can get your device back up and running as soon as the same day.
