If you've got a Mac that's making a weird pinging sound every 7 seconds when it's plugged in, it could be because the charger cable is loose or the USB-C port is acting up. And if your Mac starts beeping when you turn it on, there could be a few reasons why:
- Low battery: Your Mac will beep to let you know when the battery is about to die.
- Memory or firmware issues: Your Mac might beep if it can't find the memory, if the memory isn't working right, or if it's fixing its firmware.
- RAM faults: If your Mac keeps beeping and won't turn on, it could be because of RAM issues.
Here are some beep codes to look out for:
- One beep every 5 seconds: Your Mac can't find the memory.
- Three beeps, then a 5-second break, repeating: The memory isn't passing a check.
- Three long beeps, three short, then three long: Your Mac is fixing a firmware problem.
So, if your Mac is making strange noises or beeping at you, it might be trying to tell you something important!
