It's the first time that I've heard this beeping except when I installed a firmware update a few weeks back. I restarted and held down the 'option' key again, booted into Windows 7 fine, and have since rebooted into OS X as well without issue. The fans started running pretty quickly and I held down the power button and it finally shut down. It beeped 3 times, stopped, beeped 3 times, stopped etc. What was unusual, however, was that it immediately started beeping loudly when I held down the option button and continued to do so without ceasing. This morning, when I got into work I restarted my Late-2010 MacBook Air (128 GB HD, 1.86 GHZ Core-2 Duo, OS X 10.7.3) while holding down the 'option' button as I normally do to access bootcamp and load Windows 7 because I need to use Excel Macros during the work day.

MacBook Pro, Mac OS X (10.6.3) MacBook Air :: 3 Beeps Continuously On Restart? Mar 9, 2012

#Macbook pro 3 beeps no post install#

System install was a success and was able to restart machine B successfully from the hard drive of the faulty machine. Did a clean system install from machine B (while still in target disk mode). Hard drive checks out with no errors and is formatted in Extended Journaled. Fired the machine up as a target disk and ran disk utility via remote control from another machine, we'll call that one 'machine B'. Bought new ram, put it in, reseated it a bunch of times, still three beeps every time.Attempting to restart using the system DVD by holding the C key, same problem. Computer starts with normal chimes, then when it gets to the grey screen with the Apple, I get the 'three beeps'. Now I can't get as far as the password screen any more. So I attempted to boot from my own Snow Leopard DVD, then I started getting three beep errors. I thought this was going to be an easy case of erase-and-install. My friend did not have the password to get into the machine and no original system disc. They were given the computer by someone who didn't want it. I'm working on a Macbook pro 15 A1278 for a friend. MacBook Pro i7 8GB - iPhone 4, Mac OS X (10.6.7) MacBook Pro :: 3 Beeps On Start Up? Mar 22, 2012

I then booted up this morning with a full battery and the boot up took a lot longer than normal - maybe around 3 minutes on the spinning logo, and then finally booted - are these all worrying signs?

This i7 is coming up to its first year (which I think is covered by Apple?) and I *think* this maybe a memory issue? If it is, and my Mac is covered, then by a sheer stroke of luck, I decided to get Apple to fit the 8GB memory at the time of purchase (bad I know! and I don't usually do that) BUT that would mean that Apple fitted the memory upgrade and I haven't touched anything myself. However this time, I had the frozen screen saver, and a continuous 3 beeps which I've never had before in a loop? I then re-pressed the power switch on the Macbook and it rebooted fine and seems ok. I get a frozen screen saver which is normal, while the progress bar finds it feet back on power. My Macbook Pro battery had run down (it does quite a bit) so I rebooted with the power inserted. Intel Mac :: Turns On But Just Beeps Three Times Stops Beeps More Times And Won't Start Up Jun 16, 2012 I waited ten minutes and did some quick research on my ipod. I pressed the power button until it was quiet.

Talk about a rude awakening! The screen was dark and did not respond to keys or mouse clicks. I keep my laptop running most of the time, and at 4 o'clock this morning it started beeping at me. If you do not want to check it yourself, you can take the computer to the Apple store to have it fixed. 3 beeps usually means that memory modules may not be seated properly or not working properly. If you meet this last condition, either deinstall Google Drive or upgrade your Macintosh operating system. A last dark horse that could cause this triple beeping is a strange bug while running Google Drive software on a Macintosh running 10.6 (Snow Leopard). A looping three beeps in between three seconds during startup is your iMac’s way of telling you that the operating system you’re trying to boot into is incompatible with your Mac hardware.
