Here's a tip from Apple's website that mentions exactly what you're seeing: "3 long beeps, roughly three short beeps, three long positive beeps." I couldn't put Apple on "3 easy beeps, 3 huge long beeps, 3 fast beeps." These several tone combinations are clearly not the same overall.


How do I get my Mac to stop beeping?

RESET PRAM
  1. Turn off your computer.
  2. Find the following keys on your keyboard: Command, Option, P, and R.
  3. Turn on your computer.
  4. Hold Command-Option-P-R.
  5. Hold the buttons until the computer restarts and you hear the startup beep a second time.
  6. Release the buttons.


Mac computers may want to play multiple tones when properly started. Your Mac should make a unique warm sound when it starts up. If you hear a different sound, it probably indicates a problem with your computer.


What do 3 beeps mean?

Three beeps that repeat after a pause and appear when the computer is turned on indicate a problem with the system memory. The beeps will continue until the computer is turned off, then play again after turning on if the problem is not resolved.


1 large beep when the Force button is pressed: Indicates that a pre-2012 computer system has had significant improvements in EFI ROM.
