Thank you. My Mac started beeping at me the other day and I am hoping that somebody can tell me why as it was definitely abnormal beeping.
Macbook software update loud beep
I have a macbook pro 15 inch aluminum unibody that was the latest model when I bought it back in January this year. I have not added any ram or changed the hard drive or added any third party hardware to the computer. I am running Mac OS The computer had been going with with nothing unusual and I was browsing the internet in Safari when suddenly I heard this disturbing beeping coming from my mac. The sound was quite short and quite loud. It reminded me of the beeps made by macs when you reset the pram.

The beeps were quite random. The beeps seemed to become less frequent when I disconnected from airport and more frequent when I reconnected. Eventually I changed user and then left my computer for a time and then changed back to the affected user and the beeps had stopped. The beeps were definitely not my system alert sound as it sounded quite different. Also they didn't respond to changing the system volume, whereas my alert sound did.
I ran disk first aid and it came up with nothing. The only unusual thing is that later that day I was watching a movie on my computer while unconnected to the power supply and my computer ran out of battery life. Instead of going to sleep it shutdown. I restarted it after connecting it to the power supply and there was no problem.
Loud beeping sounds on MacBook Pro
Does anybody have any clues as to what might be going on? Disco all connected peripherals and see what happens. It sounds like hardware otherwise. It sounds like its still covered under warranty so if it needs to go in, just make sure you do a time machine backup first as any shop you take it to will more than likely send it to Apple depot for repair. Assuming not, what is it trying to tell me?
V2Blast 5 5 bronze badges. I had a near identical problem that was caused by - what seemed to be - loose ram.
I unscrewed the back, disconnected the battery, took out the ram, inspected for damage none I could see , flipped the positions of the cards for good measure, and it booted fine. One additional problem that I had had was that if the keyboard flex when moving, the computer would shut down or restart.
No, your Mac is not possessed. I'd be hesitant to recommend this—if it doesn't boot from the CD, is it really likely to boot from the disk? Kevin: A similar process for installing Windows 10 on older iMacs works just fine where Bootcamp is limited to Windows 8 , so it might work okay.
Kevin Thanks for the comment. Hopefully the OP will report back either way. If you have any other questions please feel free to ask. And thank you for coming back to share your results, it's sure to help others down the track! Monomeeth You're a legend! I followed your steps and my Mac is now purring nicely on Snow Leopard.
