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.
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).
Today just woke up and turned on my iMac. It started with apple logo then I saw a cancel logo which shocked me..

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.Â

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.

When i started it on i saw that even after two or three minutes it didnt started. i am still stuck at the apple logo on startup.

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.

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)Â
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.Â
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.Â
During boot Yosemite shows a grey screen with the Apple logo and a progress bar - is this normal?

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. Â
1. I've tried zapping the PRAM. Didn't have any changes.Â
2. I tried starting up in safe mode, but getting passed the apple logo is required for thatÂ
3. I tried single user mode, but getting passed the apple logo is required for thatÂ
4. I tried holding the c key to start up off of the dvd, nothing happensÂ
5. I tried holding the mouse button (and cmd, opt, f, o) to manually eject the dvd during start-up.Â

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.

IT does this every time, but when I do command and r or other such keyboard commands, it goes I the recovery pahe with no problem. Whenever I tried erasing the iMac to reset it, it said the disk was locked.

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.

Hes addicted to the glowing apple logo on the back of my macbook, he wont leave me alone, he wants it lol.
How can I turn it off?
Pretty smooth sailing until I had to reboot my mac pro. It just stops at the point where you have the grey Apple logo and the spinner.
My one year macbook pro is starting with the apple logo and a statusbar, and afterwards it shows the logo and a spinning gear. This is all that happens.

I have had my MacBook for almost two years and the battery had just died on me. So I sent it back to Apple and got a new one. But ever since switching over to this new battery, my computer has had issues starting up. A grey screen fades into white and the Apple logo never appears. The computer will just stay like that for hours. A friend suggested turning the power off and back on, holding apple+ctrl+P+R, which worked. However, the next time I turned my computer on, the screen stayed white again, without an Apple logo. Can you tell me what the deal is? Should I bother reporting this to Apple? Is this permanent damage I'm going to have to go thru everytime I start me laptop? Any way to fix it? Thanks.

Sometimes, when I try to turn off my computer, it doesn't shut down. It would either quit all programs (including finder) and just show the wallpaper, or it would go to the blue-ish screen (a normal phase in the shutdown process) and the wheel on the bottom would spin forever. In either case, the computer just freezes at that point and I have to power cycle it manually.
I noticed that this occurs more frequently if I don't restart it for a couple of days (3-4 days max), but my friends are able to go on without a restart for 2-3 weeks at a time. I tried reinstalling OS X to no avail. I now also quit all my programs manually before I try to shutdown (don't know if they affect anything) but that does not appear to help. I'm using a late 2008 MBP with OS X 10.6.5 (10H574)
Hi all, I have two Powerbook G4 laptops. Both have very similar problems. When I try to start up, the grey screen with the apple and spinning wheel appears, but I can't get beyond that. If I walk away for an hour, when I come back there will still be a grey screen with apple and spinning wheel.
I admit I know little about this sort of thing, so I began poking around online for solutions. I tried Tech Tool Deluxe. Inserted the disk and held down "C," but again it never progressed beyond the grey screen with apple and spinning wheel. Most frustrating. Is there any other way of running the disk with the laptop?
Entering the terminal yielded slightly different results on each machine.
Powerbook #1: Once in terminal I typed...
/sbin/fsck -fy
...response was...
disk0s10: I/O error.
Invalid Key Length
(4, 44890)
** Volume check failed
...tried /sbin/fsck -fy over and over, always received the same results.
Powerbook #2: Once in terminal, this appears...
jnl: update_fs_block: failed to update block 1073777488 (ret 5)
jnl: journal_open: Error replaying the journal!
hfs: early jnl init: failed to open/create the journal (retval 0)
...and it won't even let me type /sbin/fsck -fy.
I tried plugging both latops into my desktop in target mode. In both cases the target icon appeared on the laptop screen but the hard drive icon never appeared on the desktop screen. I would love to at least retrieve a few files off each machine, if nothing else.
Holding option doesn't work, taking out the battery doesn't work, running out of ideas.

my first night with my new Macbook was last night! All is great so far, just one questions though. When I was in the bed las night, the apple logo was so darn bright in the bedroom it woke the wife up once! Can I turn that sucker down a little for night time use, or should I position the pillow to cover the back up?
View 3 Replies View RelatedI have narrowed the problem down to a faulty hard drive, I did this by successfully installing snow leopard on an external and booting from there, however, when I start the mac, press the option key and select the external, it initially sits there on the apple logo and cog, but after a while that apple logo disappears and is replaced by a circle with a line through it, much like a no entry sign.
View 1 Replies View RelatedRecently my Mac has been extremely unstable. It keeps freezing up and hanging for no reason. Initially a 3 beep would sound off, I ran some tests like the apple hardware one and realised that one of the rams was bad. I bought 2 new sticks of ram and replaced it. Following which, the mac still freezes up and a 3 beep alarm sounded off again.
Currently, I'm trying to turn it on, no 3 beep signal is sounding off but the Mac either keeps freezing and showing a highly pixelated screen or a black screen surfaces. There is some sound coming off from the laptop as well. Each time I switch on the system, it just shows a black screen with no display.
The Mac is a 15'' 2.66 MHz i7 which was manufactured in the mid 2010s.
The 2 new sticks of ram are Strontium 1066Mhz 4Gb x 2 sticks.
In the initial stages: kernel panics were common as well.

Does the Apple logo still light up on the MacBook Air whenever the screen is on? Like this:
