Mac Pro :: MacPro Died - When Powering Machine Hear Startup Sound And Display Shows Apple Logo
Nov 28, 2010
My early 2008 2.8GHz 8-core Mac Pro died last week. I tried all the usual stuff and ended up taking it to the local Apple store genius bar. They ran their diagnostics tool on it and did not find any problems so I had to leave it for a more thorough test. The Apple Store called a few days later and said it was either the main logic board and/or one or both CPU's. They -say- they replaced the main logic board and that did not fix it. They told me it would be ~$2800 USD plus labor to replace the the main logic board and both CPU's. So I took the machine over to another authorized Apple Service center for a second opinion. This other service center seemed confident they could determine which component(s) are defective. I am expecting a call from them on Tuesday of this week and hope to find out more then.
The symptoms are: When powering the machine I hear the startup sound and the display shows the apple logo. The machine boots for a little while (disk activity is heard) then the machine freezes for about 30 seconds then reboots or just freezes indefinitely. This happens with my 10.6.5 boot system, a second 10.6.x boot system on another internal drive as well as from the 10.6 SL DVD installer disc. Apple could not boot it off their network based systems either. Same symptoms on all startup disks tried so far...
So, I'd like to know where to go if I need to obtain parts and do the repair myself. I've built a number of PC's in the past and have no concerns about the undertaking. I just need to determine which parts I need. I'm not looking to "upgrade" the machine however if faster CPU's are available for a similar price I'd probably opt for the upgrade. At this point I'd be completely satisfied replacing the defective components with the same stuff that's in the machine now. Any pointers/links/tips/etc. would be most appreciated.

It's my understanding that the start up chime you get when you start up on any Mac,c an NOT be changed because that sound is in the firmware. Cool.
That being said, is there anyway to add/hear your own custom sound clip AFTER that?
Does any one know how to do it?

On Christmas Eve my 6 month old MBP 13" hard drive packed up - got the apple logo and nothing else on boot up. Apple Care phone support couldn't fix so had to send it off for repair (due back this week). I know there are more important things in life, but to have spent a month's wage on a computer and to be let down like this was really disappointing. My last backup was a month ago, so everything since has been lost, and I was without a computer for two weeks. Is this a common fault? What bugged me most was that at no stage did anyone from Apple offer any glimpse of an apology for the floored (and very expensive equipment). I switched from Dell to this and love the computer, and had heard a lot about Apple's amazing customer service. Not what I've experienced.

I currently have an imac and its slow.Its the first intl 2.16 ghz white one. I would like to use my new 13" macbook pro for my photoshoping and video editing needs since its pretty fast. I was wondering, if the graphics card is powerful enough to connect to the new LED apple display 24" i believe.

So, I think my PM G4 finally died. I had been using it as a media annex (not center) in my living room since my 22" Apple Cinema Display still works fine. Now I'm stuck with a 22" monitor that can't be connected to anything. I've been looking into what can be done. Based on an Apple Support Document, there is a M8661LL/A part called "Apple DVI to ADC Adapter" that I think will do the trick. If I get it, I should be able to hook my PowerBook G4 up to it, right? If so, the next task is to find the sucker. searching online for the part number didn't yield much, but I did find a nearly identical product number, the M8661LL/B on Amazon for $90 (yikes!!). The only difference is the suffix letter. But I don't know enough about this to really know if it'd work.

Why does the apple logo briefly turn red when I switch on my Macbook Pro before reverting to grey and starting up normally? I hadn't noticed it doing this until recently.

I am fixing this 2007 iMac for free for an autistic child. Apparently, changing computers for someone that is autistic isn't ideal. I don't have the history with this iMac, just that it isn't working. They supposedly did have the hard drive replaced? It sounds like a dvd is inside it when it starts up, could be the installation dvd?Either way, I have not seen it before where the Apple logo refuses to show on the start up screen. It just stays gray.
1. I've tried zapping the PRAM. Didn't have any changes.
2. I tried starting up in safe mode, but getting passed the apple logo is required for that
3. I tried single user mode, but getting passed the apple logo is required for that
4. I tried holding the c key to start up off of the dvd, nothing happens
5. I tried holding the mouse button (and cmd, opt, f, o) to manually eject the dvd during start-up.

I forgot to switch on the power socket at the wall so when I came back it had powered off. When I switched it back on it showed the last screen visible before sleep mode kicked in and then showed the apple logo with a progress bar underneath. The progress bar starts to move slowly but after about a minute starts again. It slowly starts to move again but stops after about two minutes and the macbook powers off.

I own an iBook G4. I could not get it to boot up, it would just go to a grey screen with the apple symbol and a timer/clock that looked like a gear.FYI: I may provide more information than necessary in the text below. I'm not sure what is and isn't relevant.
Following some advice I found in this forum I got out my old OS disks to boot from the disc instead of the hard drive. I intended to archive the old hard drive and install my latest OS (10.4.6 on the disc, 10.4.11 was the version I had been running on the machine, I believe). The machine told me it needed 4.5 Gb to install 10.4.6 Tiger, but I only had 4.0 Gb left on the hard drive. So instead, I archived and installed with the OS that came with the computer originally, 10.3.4.
I got things going, did the archive and install, and got to the log in screen. Unfortunately, I could not remember the password, so I booted up in single user mode, and entered the following to get into the machine:
1. mount -uw /
2. rm /var/db/.AppleSetupDone
3. shutdown -h now
This got me in with a new admin login, and I started up in 10.3.4. I soon noticed that I could still see all of the files that I put on the hard drive on my old operating system. I thought I shouldn't be able to see them, but since I could I decided to try to copy them to an external hard drive. When I did, I got an error message saying that there was a read/write error. I was not entirely surprised, but I decided it was time to turn back to the forums for help.
What I want to do is copy everything from my old hard drive onto an external hard drive, make room on the iBook hard drive to reinstall my latest operating system (10.4.6). Once I've done that I'd like to get the essential files back onto the iBook from the external hard drive and continue using my computer (even though it is a dinosaur).

I just bought a new 27" iMac and when I start it up I get a white progress bar under the apple logo. When it does come up, iTunes will not play and sometimes the computer will not recognize the magic mouse or my WiFi. Everything works fine after I re-start.

I recently noticed the Apple logo is magenta at start up, when it is centered on the screen, before it turns gray and moves up the screen to make room for login details. I cannot replicate the issue on restart but only see it when it starts up first thing in the morning. It literally flashes up for just a second or two then normalizes to gray.

This situation began when I put my Imac on sleep. After, the screen turned on in black whit the cursor but I couldn't do anything.
Then to rebooted the machine, the apple logo and sound began fine but the screen turned off, so moving the mouse the screen turned on in black with cursor.
I'd tried many ways, resetting the PRAM, SMC, repairing the disk and permission, analyzing hardware, repairing fsck files.
Suddenly, when I entered in Verbose mode, mi imac brought into user choose screen and worked fine, but when I shut down and tried to start my mac in the next day, it didn´t work again.

I have a MacBook Pro from 2010 I believe with iOS Maverick installed. (MacKeeper is also on there, which I just found out is apparently malware)
So three days ago I was watching Netflix, the image froze, but the audio kept going. Figured my internet was slow, so I waited a little, nothing happened. pressed escape to leave the full screen mode, but nothing happened. None of the keys would do anything, not even the sound or brightness keys. So I did a force shut down by holding down the power button.
I waited a little, then decided to turn it back on. Start up sound played, white screen with grey apple logo and loading gear appeared together with a grey loading bar. I figured that this meant it had to repair something. But after about a minute or two it just went to a black screen/ shut down. I left it off for a day, tried it again, same thing. Next day I tried booting it up while holding the shift key to do the safe boot (I knew it wouldn't work since I already had the grey loading bar anyways), same thing happened.

I have a Rev A 12 inch Powerbook - 867 mHz, 640 RAM, 40 GB hard drive. The machine's always been reliable and has performed great over the years. I bought it the last week of July, 2003.
Yesterday, the Pbook was shut down, and I press the on button so it would boot up. Almost immediately, the hard drive makes a loud, whirring noise. The computer advances to the gray screen with the Apple logo, but it doesn't get past that point and the noise continues, as if it's a car engine that just won't start...
I'm going to take it to my local Apple Store in the morning, and hopefully the data, including my nearly 22 GB of music, can be saved. Any thoughts on how to get my computer working again? By the way, it's the original hard drive installed. Hopefully this is enough info to generate some ideas, I'm stumped.

I purchased a new late 2013 27 inch iMac 3.4Ghz i5. The only thing I did after pulling it out of the box was restore Time Machine from my previous iMac. On startup the machine boots as expected, but gets interrupted by the screen turning a dark blue, and the apple logo turning bright red, for about a second or so, then boots as normal, and opens Mavericks. I've spoken to Applecare - they suggested I re-install Mavericks, which I did. The problem is still there. I've done a hardware diagnostics test - no problems. Though I wonder if it could be a faulty graphics card? As far as I'm aware there are no other issues with the iMac. The machine is under warranty but would love to solve this if possible.

My Macbook Pro (early 2013, OSX 10.9.4) does not come to sleep mode – 10 secs after closing the display lid apple logo starts glowing (blinking) on a random intervals.
I have tried the following methods that HAVE NOT solved the issue:
* PRAM reset
* SMC reset
* Power Nap is disabled (with enabled I still get the same issue)
* WiFi is off
* Bluetooth is off
* no external devices connected
* no antiviruses or other programs that I would suspect to cause this
* sudo rm -r -f /Library/Prefrences/SystemConfiguration
* finally reinstalled OS X, and I still got the same issue
Surprisingly, if I enter to sleep mode via menu: Apple>Sleep, there seems to be no issue! I have tried changing pmset -1 lidopen 0 to validate if lid is preventing from going to sleep mode, however it has not fixed the issue.
I see this text in the Syslog:

I can only hear but not see TV shows downloaded into iTunes. I've never had that problem in the past. I have a MacBook Pro, 2.5 Ghz intel core 16 GB of memory. I've always watched TV shows and movies through iTunes on my computer, and all of a sudden I can't see the image. I image the problem is a setting in iTunes, but I can't find anything that will resolve the problem.

A few weeks ago I had problems with my iMac freezing and also had a few Kernal panics. I ended up doing a disk utility with the actual startup disk and since then it worked for about 10 days but just recently froze again (while in Firefox) and started making a continuous loud beeping from the speakers and kind of a staticy sound...so I turned it off but now it won't stay started. I hear the "bong" noise and then see the apple logo and the bar under apple logo starts to come on but disappears And then it powers down to black screen and off. I have tried putting disk in but it spits it out at startup I have also tried Resetting pram and smc...I hope I did that correctly I believe I did? What other steps can I take?
