    The following is from this Apple document: Mac computers: About startup tones - Apple Support

    Mac computers can produce several sounds when starting up. Your Mac should produce the familiar single tone on start up. If you hear another tone it can indicate problems with your computer.

    • 1 tone, repeating every 5 seconds: This indicates no RAM is installed.
    • 3 successive tones, a 5 second pause (repeating): This indicates RAM does not pass a data integrity check.
    • 1 long tone while holding down the power button: Indicates an EFI ROM update is in progress on a computer manufactured before 2012.
    • 3 long tones, 3 short tones, 3 long tones: Indicates EFI ROM corruption is detected and the computer is in EFI ROM recovery mode.

    Should you need to restore the EFI ROM on certain Mac computers produced before 2008, you'll need to use a recovery CD to restore the EFI ROM. Newer computers automatically recover from a corrupted ROM; when this occurs a progress bar appears on a grey background. Do not disturb the machine while the ROM recovery is taking place. It will restart back into OS X when it restarts. For more information on EFI ROMs, see EFI and SMC firmware updates for Intel-based Macs.

     

    Which is it?  If just one beep every five seconds check the RAM in the Mac to make sure they are seated firmly

     

    Do you have any 3rd party RAM installed?
