If all else fails, there’s a chance that there’s an issue with some internal component on your MacBook. If any issues are found, Apple Diagnostics suggests solutions and provides reference codes–write or note these codes down.
It’s also a best practice to download and install the latest currently available version of macOS. This will address a variety of software-based issues.
From there, you can reset the NVRAM and SMC (you can follow our previous guides on doing so). We recommend running through some standard troubleshooting. But there could always be buggy behavior on your individual machine. At this point, we haven’t seen any widespread bugs with the power chime on Mac devices. But if you’re running into issues with a repeating or random power chime, try removing the dongle or hub and assessing whether that was the problem. There are plenty of good quality dongles and hubs on the market. Because of that, many users have likely resorted to third-party dongles, adapters, and USB-C hubs. This is likely even more of an issue on modern MacBook devices since they’ve ditched all ports in favor of USB-C and Thunderbolt 3. Speaking of counterfeit or lower-quality accessories, there’s a chance that something in the charging chain is affecting the power chime on your Mac device. And in the worst-case scenarios, they can actually do harm to your computer. Shoddy charging cables and counterfeit accessories don’t function as well. Of course, the standard advice is to buy a Thunderbolt 3 cable and other charging accessories directly from Apple or another third-party brand that you trust. We recommend trying to charge your Mac device with another Thunderbolt 3 / USB-C cable and seeing if the problem persists.
If you’re using an older Thunderbolt 3 cable, it could very well be the sole cause of the problem. Loose cableĬables degrade over time - that’s just a face. There could be quite a few reasons why you’re running into problems with the power chime. Troubleshooting the charging sound on MacBook There are a variety of things that could be causing problems with the power chime on your Mac or MacBook device.
More specifically, we’ll walk you through how to fix any problems with a power chime that keeps going off intermittently or at random. (It’s also exactly the same as the charging chime in iPhones post-iOS 7.) While the sound could just as easily be called a charging chime, it’s explicitly referred to as a power chime within macOS. Apple presumably added this in because the USB-C cables don’t have a charging indicator.
When you plug a charging cable into a MacBook Pro or MacBook Air, it’ll make an iPhone-like sound to indicate that charging has started. The startup chime has been removed from virtually all newer Mac devices. To be clear, we are talking about the power chime on newer Mac devices - not the startup chime.
