MacBook Pro :: System Hangs At Apple Logo Boot Screen / RAM Not Allowing System To Boot
Jan 5, 2011
I've been reading this site for a while now, first time I'm posting. I recently purchased 8 GB of RAM for my 2010 13" MBP. There are two 4 GB DDR3 PC3-10500 1333mhz sticks. When I install them in the laptop my computer does not get past the apple logo boot screen (the spinning disc freezes). However, I can boot into Windows (boot camp) without issues.
Also, when I pair either of the 4 GB sticks with one of my old 2 GB stock sticks the laptop boots up fine in OS X. The system profiler registers it as 6 GB of 1067 mhz RAM (the stock sticks are 1067 mhz)

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).

After recently doing a fresh install of Snow Leopard, it was working great for about a week, and now it hangs at boot and flashes the Apple Logo, a NO sign, and a folder sign. I booted in verboose mode and it say that it could not load drivers.
I had this problem before and I used Leopard's (10.5) Archive and Install feature to fix it.
Where is this located on SL (10.6) ? I DO NOT want to loose my data

I have a mac pro running leopard (purchased in 2/08) and it was running beautifully for almost 2 months with no hangs, crashes or freezes. Then, for some reason, today when I turned it on, it would not boot. It would get to the apple logo, then just sit there for a few minutes, then reboot itself and the same thing would happen. I pulled out the ethernet cable, unplugged all usb except keyboard/mouse and it would then (sometimes) boot into the system, log me in and present me with the UI.
I then quickly performed a soft reboot and it would get to the desktop. However, I can only use it for anywhere from 30 seconds to 5 minutes before it would completely lockup. The clock freezes, the mouse freezes and it just sits there forever. I have tried booting into Vista (BootCamp) and it also freezes before startup is complete. If I hold down Option and then select the System disk, it will either just hang forever or get to the desktop and then freeze again....................

Macbook: A1181 Core 2 Duo 2.0ghz 1GB RAM
DVD disk: Leopard 10.5 Retail install
Hard drive: dead (spins with clicks).
With regular startup I get the flashing question mark and can hear the failed hard drive click and spin. After getting the DVD to boot in the drive (it doesn't suck it in right away), I get an apple logo and pinwheel like I should, but after about 30 seconds it goes to a black (blank) screen and the DVD spins down, but not all the way. The computer is still on, but nothing happens.
Oddities:
<>If I start it with an iMac 10.4 DVD I can boot to the install screen just fine, but can't install because it's an iMac DVD. I can erase and partition the drive fine (not the dead one, another one I have).
<>Safe mode boot does the same thing, but takes 20 times as long to boot
<>Retail OSX 10.4 DVD does not boot at all, but that one might be for PowerPC computers. I get the flashing question mark folder.

My macbook is driving me insane now. Just recently, my macbook has occasionally flickering screen and freezes after that. Yesterday, when I was watching youtube on fullscreen, it first has flickering screen, then freezes. So I hard booted it pressing the power button. Then, when I try to restart it, it won't boot pass the apple logo no matter what. Here's my macbook spec2007 Summer Macbook Pro 15"Snow Leopard 10.6 OS XI cracked my screen once, and got a replacement, don't know if that matters.
I've tried the following:Safe mood reboot, the progress bar goes about half, then disappears and stalls again.Booted in verbose mode but it gives a warning message: 'com.apple.driver. internal modem support declares no kernel dependencies; using com.apple.kernal.6.0'. Booted in Single user mood, and typed fsck for disk repair. After checking said the volume Macintosh HD appears to be ok. But still won't boot pass the apple logo after restart.Boot with installation disk pressing C at startup.
Success after a few try: Opened Disk Utility and did disk repair (no problem found). Reinstalled Snow Leopard OS X 10.6. This time it booted with Finder and everything for a short while, then the screen flicker and freezes again (before I can backup anything!). Then, I can't reboot pass the apple logo again. When I try to reinstall Leopard OS X 10.5 with installation disk, the macbook seems to try to read the disk, but won't boot. I've got a CD stuck in the optical drive now.

This morning, I would turn it on and it'd go to the grey screen with the Apple logo for a few seconds and then go to the icon that is a circle with a line through it. After reading online, I was able to boot it up in Safe Mode. I went to Startup Disk in Preferences. I chose the MAC OS X, xxxx and then clicked the lock to prevent further changes and then clicked restart. Now when I turn on the macbook, it goes to the grey screen with the Apple logo for at least two-three minutes and then just shuts off. Won't boot into Safe Mode now. I already tried the Command-Option-P-R keys trick like five times.

For several weeks, my black MacBook (2008) has been acting odd. Certain applications won't open, and when I attempt to open them, the computer makes a quiet clicking noise, like the drive is failing. Last week, when trying to boot it, the thing just wouldn't. Stuck on the grey Apple logo screen. Assuming a hard drive problem or failure, I ran the tests. I ran Disk Utility from the Snow Leopard install disk, checked & repaired permissions, checked & repaired disk. All okay. I ran the Apple Hardware Test from the install disk that came with the computer, using the test that runs for an hour or so, and all appears to be fine. The computer won't boot into safe mode. I've tried flashing the PRAM. I doubt I could achieve much through target disk mode, as I've already run Disk Utility. What's left to do? Something doesn't add up here.

I'm trying to repair a Powermac G5 (dual 2.0, the first model I believe, with a new Radeon 9800 graphics card) that won't boot and I'm having some problems that I can't seem to diagnose.
The machine will boot to the openfirmware prompt or target disc mode and will show the 'OS not found' icon if left to boot from the HD (which has been wiped). If I try to boot from either the included restore disc or a retail 10.4 DVD I've tried it will show the boot screen with the Apple logo on it but no spinning status indicator underneath. It just freezes on that screen. Once it showed the status indicator but it just continued to spin for about 30 mins, at which point I gave up. Same issue if I try to boot the hardware test (except it freezes on the hardware test loading icon rather than the Apple icon). The superdrive appears to work as it is accessible in target disc mode.
I've reset the SMU and reset the PRAM via the keyboard shortcut. The one thing that leads me to think it's a firmware fault is that when I run the 'reset-nvram' command it gives an OK, but when I then run 'reset-all' it freezes rather than rebooting. Any ideas anyone?

Sometimes, when I turn on my iMac (10.6.2), the system will not load, you can see the grey screen but empty, no apple logo there. I have to force a shutdown pressing the power button and when I turn it on for the second time it will work properly.
It only happens once in a while but I cannot understand why, since nothing changes.
PS.- I have verified my disk with the disk utility and everything seems fine.

My mid 2010 iMac i7 will not boot past the apple logo? I'm running 10.7.3. I have tried restoring from TM backup from recovery mode (worked the last time this happened) however upon completion it returns to the recovery screen? I made a disk of Lion when I downloaded the first time (followed same instructions sourced from numerous websites) which does not seem to work when i set to start up from this disk, just gets to the grey screen and flicks between the apple logo, a folder icon with a question mark and the circle with line through? Now I can't eject the disk either, a message appears that system can't eject and to make sure all applications are closed? Not sure how to go about closing these applications without being able to start the system? When I tried booting from the Macintosh HD I got a message that the boot cache partition was faulty? I have ran disk permissions etc all ok.

I had been using my iMac all night, when all of a sudden the bouncing beach ball appeared and everything became unresponsive, apart from the mouse cursor itself. It might be worth noting that a few hours prior to this, I plugged in an external hard drive to burn off a DVD. This external hard drive has two partitions, the first being a restored image of Leopard; and the second, my out of date backup ("yes, I know").
I subsequently restarted my machine, enjoyed the chime, pondered the excessively long start up and looked bemused at the Leopard Setup wizard. I realised that the restored Leopard partition had booted up instead of the internal disc. So, I unplugged the external drive, pressed reset on the iMac and was immediately greeted first by the reassuring chime, then by the Apple logo and a lingering grey screen and finally by a flashing dark folder icon with a question mark in the centre for eternity.
I tried rebooting a few more times. Same. I've been frantically Googling but only found the PRAM reset and a very frightening iMac disassembly guide. I've tried plugging the external drive back it, but it refuses to boot Leopard from that now. What can I do? I feel so helpless on a Mac, on a PC I'd at least be able to open the sucker up before panicking! I've been working on a client's flash web dev project for months, and not made a back up in about half that time. The website is supposed to be going live tomorrow! Luckily I have the site uploaded, but the entire source code is potentially lost, so in the long term this is a major catastrophe!

So, today I tried to install windows through boot camp assistant on my mac. When it got to partitioning my drive I got an error that my hard drive needed repairing. So I opened up disk utility and clicked verify disk (I can't click repair) and got this error Disk Utility stopped verifying �Chris Hard Drive� because the following error was encountered: Filesystem verify or repair failed. I then researched this and learned to fix the problem I must boot from my leopard install disk and use the DU from their. Unfortunately I don't have access to the disk. But I have the install disk from my old macbook (the white one) so I used this. I put in the disk and shut down. When I turn it on I hold C but all I get is a grey screen but with out the apple logo. When I try turning it out holding alt I don't get the option of the CD just Chris Hard Drive. But when I boot up holding D i do get to the hardware test screen but I get the error that's something like "Hardware test does not support this hardware". Will the Leopard install of a different type of macbook not work on my new macbook pro (13" aluminium)?

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 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.

Just an FYI. Tech Support at Allsoft states The Disk Warrior 4.2 Boot DVD will not Boot the new 2010 MBP's. They are waiting for information (software) from Apple.
Will need to use Target Mode or another Mac connected with Firewire till then. Boot from that then run DW from your MBP.

The other day my 1st gen MBP functioned without any probs, until it suddenly powered down. After I removed the question marks from my eyes, I offcourse tried to reboot it.
But it never makes it beyond the grey screen, sometimes untill the apple logo, sometimes not even that far.
Offcours I googled around first to gather some info before I decided to put this problem down on this board. I found this could be a HDD failure, but in those cases, with other people, it could be powered holding apple + s, and doing some checks that way.
Mine doesn't even come that far
I have a second hand 1st gen MBP with upgraded HDD and RAM, snow leopard, and coincidently since last week no more battery... so i may have powered down a completely unprepared mac by tripping over the wire, once or twice...

I tried fsck -f fsck -y multiple times, booting in safe mode, zaping the pram and all that stuff, nothing as worked. I don't really care about how to fix it but I care more about, Is there any possible way I can get files off of the macbook even though it wont boot. Like is there a way for another computer (windows or mac) to pick it up so I can transfer files? What accessories will I need?

Since a few days ago my Macbook Pro 13" from last June started to freeze randomly for atleast 30 seconds and then it would come back and most of the time freeze again after a while (in OSX only it seems, Windows 7 I did not have such problems, though I didn't use it often). Sometimes it occured frequently, other times it didn't and this morning I had the same thing again, I just held the power button and shut it down, did this two times in a short period of time and when trying to boot it for the second time all I get is a gray screen with no Apple logo or anything.
Searched the forums, tried the install DVD and C button to no avail, same thing with trying to reset the PRAM and NVRAM...Is the logic board broken or anything? I don't understand how this could happen...And if I do take my laptop to Apple, should I remove the Intel SSD drive I got in it right now and put in the stock?

The little progress spinner thing below the apple just spins and spins. The computer said that several apps stopped responding and had to quit after falling asleep watching a movie in VLC, which had error logs that had frozen on the screen as well saying, "Computer too slow?" from dropped frames apparently. Not normal. Also, yesterday, when waking it up from the display shutting down, the whole screen was gray and smeared looking. There was nothing recognizable at all on the screen, and I hit the power button quickly for it to sleep, and back again and it worked fine for the rest of the day. Its a 1.66 Core Duo Mac mini w/ 2gb of RAM.

I have a major problem with my first Generation MacBook Pro. It won't boot anymore: it just turns on and gets stuck at the Apple logo. There is no spinning wheel and nothing else happens. Pressing 'C' for booting from CD or pressing ALT and choosing the CD as an alternative boot source does not work either: it just does exactly the same, gets stuck at the apple logo. I already tried resetting the PRAM and NVRAM, as well as the SMC. This also did not change anything. CMD+V mode starts up then stops at the line "ACPI: System State [S0 S3 S4 S5] (S3)"
What can I do? I really need to save my Mac, there is some really important stuff on there
