MacBook :: Won't Boot Up / The Laptop Fails To Boot Up?

May 11, 2009

Just recently got back from a visit to my local Apple store in regards to a faulty power adapter. My Macbook started up fine at the store, as it has over the past two years. However, after getting home and trying to turn it on, the laptop fails to boot up. It sits at the grey screen with the Apple-logo and spinning progress circle, all while the fan starts to whirl as if my macbook were on fire. I've experienced a failed hard-drive before, so I know of the folder w/question mark screen, and this screen is not like that. I've also tried booting up in "Safe-Mode," but that won't work as well. I do have a start-up disk and external hard-drive... I'm just curious to see what other options I might have before reinstalling Leopard.

MacBook Pro :: Fails To Boot Properly After EFI Firmware 27 Update

Apr 16, 2012

I have a strange boot issue having (tried) to install EFI 2.7 update. When I restart the laptop, it 'chimes', displays a grey screen, then chimes, displays a grey screen, forever. I hit the bower (off) button for 5 secs or thereabouts, and restart, same thing. I do this 4 times and finally it reboots. But the EFI update still appears as needing to be installed (software update tells me it is not installed). Update history shows however that it IS installed. I can go through this process any number of times. I now have Software Update history showing quite a few installs opf the EFI 2.7 update. If I just do a restart without installing, I also go through the same fail to restart / fail to start / ... / eventually restart sequence.

So it seems now that the laptop will only start after 4 failed restarts and finally it starts. After starting it all appears to be perfectly fine. Nothing strange in the console logs that I can see. The failed reboots don't seem to register in the console logs - I suspect that the failure to restart is pretty early on in the boot sequence, well before it tries to load any semblance of the OSX kernel. It is almost as if it is trying to boot from someplace other than the disk ... until eventually it gives up and tries the disk. (I have tried booting with and without network cable - no difference) I don't know enough about mac bootup sequences to know if there is some config/setting that is screwed up causing this odd behaviour.

MacBook Pro :: Hangs Indefinitely On Wake After Long Sleep, Then Fails To Boot

Mar 21, 2012

I installed the latest version of Lion on my mid-2009 13" MBP yesterday. I recently got a Corsair 256GB SSD (model CMFSSD-256D1) and that's what I installed Lion onto. It seems this behaviour has only been happening since I got this SSD. What happens is when I put my computer to sleep for a long period (say, 2 or more hours), when I wake it up, some of my applications show the spinning beachball - though some of the applications still seem to respond. After playing around with the responsive applications for a bit, they eventually start beachballing as well. After a minute or two the entire system is beachballed and I can't do anything. My only option is to do a hard shutdown. (It almost seems like the SSD has decided not to respond to requests?) 

When this happens and I do the hard shutdown, I consistently cannot boot my MBP at this point. I shut it off again, wait a bit, turn it on, and try booting again - nothing. The screen is all white (maybe light gray), and the animated gear never appears. I do hear the boot sound. When my MBP is in this state, none of the special boot options work - e.g., holding down "shift" for Safe Mode, holding down "option" to choose another boot drive, holding down "command+R" to boot from the recovery partition - it's as if I hadn't held those keys down at all. The only keys that do work are "option+command+P+R", which resets the NVRAM. After I've resetted the NVRAM, it still doesn't boot right away. I turn it off again, turn it on, and finally my MBP boots totally fast and fine. I do a check of the disk and there are zero disk/permission errors. 

This is totally reproducible behaviour. Every time it's in sleep mode for a few hours, it does this, and I can't boot, and the only way I can boot is by following those steps above. 

If I put the MBP in sleep mode for just a couple minutes to test it, it comes back from the sleep fine. I'm not sure how long it has to be in sleep mode before it decides to beachball on wake. 

I have done a search for new firmware for my SSD and have come up with nothing.

Power Mac G5 :: Can't Boot Into Tiger After Leopard Installation Fails

Nov 25, 2007

Installation of Leopard on my Power Mac G5 failed. After that, I can't even boot into Tiger. Whenever I power on, it just stays at the grey Apple screen. I thought changing the hard disk might help. But my experiments proved that the same behavior persists even without any hard disk. Power on, "dong", grey apple screen: that's it. What happened?

PowerPC :: Chime White Screen - Fails To Boot Up

Aug 20, 2008

So I was just there, using my computer, doing nothing out-of-the-ordinary. I decided to open up a program (Yahoo! Instant Messenger, I think it was) and the computer went nuts. I completely froze...nothing I tried worked. So I shut the computer down and tried rebooting it. It chimed and went to the white start-up screen with the apple...I let it sit for about ten minutes to let it restart. Still the white screen. I shut it down and tried it again. Same thing.

Is my computer dead? What might I be able to do to fix it? How much might it cost?

Windows On Mac :: Boot Camp Continuously Fails At Partitioning?

Feb 3, 2010

I would like to say that this is my first post on the forum. Here it comes;I'm new with mac and would like to install windows on my black 3.1 Macbook. Boot Camp continuously fails at partitioning. I've read many articles about it which say iDefrag is the solution. So I did some defragments with iDefrag (the on-line, compact and the full-defragment) and tried to partitionate with Bootcamp lateron but it did not work. What should I do to fix this.

OS X :: My Mac Laptop Won't Boot

Jul 21, 2010

im having a problem with my mac, I turned it off earlier on today and only recently turned it back on to find that it won't boot up (meaning it stays on the apple logo and swirly loading wheel and doesn't do anything) I've tried safe mode but it appears with a question Mark on a folder for a split second (this didn't happen when i tried it in safe mode)

So i tried a last resort, reinstalling my OS, bearing in mind I'm also using an external CD drive as my one inside my mac has broke. I get to the part where it says "insert disk 2 to begin in-stallion" i do so then my external cd drive stops an my laptop freezes, the loading wheel on my curser just carries on turning. I have no access to my OS at all.

Laptops :: Can G3 Laptop Boot Off A USB Port

Feb 28, 2010

I'm considering buying an old G3 500 Mhz laptop. Seller says it can't boot by itself, either through its own hard drive or an OS Panther installer in the cd drive. It does give the welcome chime but the screen then displays the folder with the question mark. So it's either the hard drive or the logic board. Anybody try to boot off the cd thru an external cd drive (with its own external power supply)? There is no firewire port on this model. Yeah I know I'm supposed to press the option key before the welcome chime.

Windows On Mac :: Boot Vista Buissness From A 2.5 Enclosure From Old Laptop

Aug 18, 2010

i was considering getting a new macbook pro 13" for high school because my laptop is really starting to act up and its really getting annoying, and i don't want to lose my homework because of my computer crashing during the school year.

so, if i take out the hard drive from my computer (120gig)(the vista computer) and put it into a 2.5 enclosure, would i be able to boot vista on the mac from the hard drive?

ive seen hackintoshes that boot from a flash drive so i was just wondering. also, is there any special way to install an OEM version of windows on a mac? i have the CD, so that is another option for getting windows on the mac.

MacBook :: It Won't Boot After Trying To Repair With Disk Utility, Cannot Boot In Safe Mode

Jun 11, 2012

I have a MacBook 4,1 with Intel Core 2 Duo processor 4GB Ram. It is taking over 10 minutes to boot up past the gray apple screen when I turn it on. First I cleared the PRam (?) then I checked the disk using Disk Utility Verify, and it said the disk needed repairs. So I ran the disk repair and it said it was unable to fix the errors on the HD.  

I did a little research and tried booting into the Single User mode, then running /sbin/fsck -fy. It said that it found errors but could not fix them. I ran it two more times as suggested and got the same result each time. I then tried rebooting and now instead of taking 10 minutes to boot up, it takes about 5 minutes on the gray apple screen and then just turns off. I started in Verbose mode to try to troubleshoot the error and it appears the last thing to come across the screen before power down is a message "Apple Yukon 2: RxRingSize <= 1024....etc". 

I decided next I would run the Apple Hardware Tester. The test came back with an error code "4SNS/1/40000001:IG0C-0.265". I am very good at searching the web but I could not find any errors that had the IG0C or IGOC or any combination at the end, but plenty of 4SNS/1/40000000(1) errors with different endings. From what I can tell people are saying anything with 4SNS/1/4000000 is a logic board failure, but this computer was literally just booting this morning until I did the /sbin/fsck -fy.

MacBook Pro :: Boot From External Firewire DVD / Optibay-Boot Camp?

Oct 13, 2010

Is it possible to boot from an external Firewire DVD Drive? It certainly isnt from an external USB DVD. Real answers only please, not "I think so" ones based on HDDs or rumours you may have heard!...

Background:
I've got an MCE Optibay in my Mid-2010 i7 MBP. When installing Bootcamp it refuses to install from the external USB DVD drive. In the end I pulled the 2nd HDD out and reconnected the internal DVD. It then worked fine without a hitch. Then I reinstalled the 2nd HDD and all was fine for a few days.

Now I want to resize my Win7 partition (bigger, as MS Visual Studio's bigger than I thought, and I might stick some games on). I can shrink the OSX partition fine with Disk Utility, but windows won't grow the Win7 one because the empty space is before the Win7 partition, not after it. Apparently this can be done with GParted. Guess what? I can't boot the Linux based GParted CDROM from the external USB DVD drive! So, will a Firewire one work where USB fails, and solve my alternative OS booting issues? If I buy one I can then either use GParted, or delete the Win7 partition and start again without having to pull the laptop to bits all over again, only to put it back once I'm done, and possibly have the same issues in the future. Obviously I don't want to blow extra money getting a Firewire DVD drive though if it's a waste of money...

MacBook Pro :: Switching The Boot Drive (want To Boot From The Optibay) How Can This Be Done

Mar 28, 2010

I run SSD/HDD, my HDD in the optibay is broken, I stuck it in a external and it makes finder freeze, it got bumped around too much so I want to put a new one back in the 'correct place' for a spinner, and stick the SSD in the optibay.(I figure the extra 2% of shock protection offered by the orange rubber circle things is worth the trouble of moving everything).

I am also going to buy a WD 3 platter 1TB laptop drive, and I read that they fit fine in the regular spot in MBP's (I'm going to open and measure in a min.)Anyways, there's no BIOS, only EFI, so how to I pick what drive to boot from? with 10.6 is it as simple as holding option down on boot, and picking my 'OSX' HDD, and then it will auto boot from that until I specify otherwise? (I ask because before 10.6 people on here were always talking about how to switch boot drives.)

MacBook Pro :: Using Disk Warrior 4.2 Boot DVD To Boot System?

May 13, 2010

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.

MacBook :: Won't Boot / Tried To Start It Back Up It Would Not Boot Up?

Feb 10, 2009

Ok so my macbook just froze up on me, and I shut it off manually. However, when I tried to start it back up it would not boot up. I am just receiving a message telling me " You need to restart your computer. Hold down the Power button for several seconds or press the Restart button. "I did what the message told me to do, and when I started the computer back up I just received the same exact message. I tried to take the battery out and hold down the power button to discharge any electricity in the laptop, and then I plugged in the power cable with the battery still out, and I am still receiving the same error message.I have tried the same process a couple of times and put the battery back in and then I decided to try inserting the Installation DVD, and it did nothing different then what I have been getting.

MacBook Pro :: Option To Boot From Different Disks On Boot?

Jun 17, 2012

I'm asking this question for my brother. He has a 15-inch MacBook Pro (late 2011). He recently reinstalled OS X Lion but now every time he boots his computer he ALWAYS gets the option to chose Macintosh HD or Lion Recovery disk. I'm tech savy but I've tried resetting the PRAM and everything else I culd think of but he still gets that same screen. He is not pressing the option key when booting it just does it automaticlly. Should I do  reinstall OS X Lion aain for him or just take it back to Apple and have them look at it?

I have tried zapping the pram, nvram, unable to boot from a disk, tried safe mode, tried verbose, did the single user /sbin/fsck -fy several times and it came back with everything appears OK.

I thought it was surely the HD but all the test say it is fine.I cannot get it to boot from a disk either.

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)

Mac Pro :: Unable To Boot / Kernel Panic At Boot And Graphics Card Failure

Mar 9, 2008

Yesterday my screen (30" Apple Cinema) started showing symptoms of graphics card failure, jagged lines across the screen. I rebooted my Mac Pro and it was gone. Then it happened again an hour later, this time the machine didn't boot, I get the Apple logo, and then it hangs up and the screen is shifted to left (I get apple logo on left side of the monitor instead of the middle) and jagged lines all over.

So the first thing I tested was using Target Disk Mode, it works. I can access my Mac Pro's internal HD's by TDM from my MacBook Pro. Then I tested single user mode, it does boot, I can't read what's written since the screen is shifted to left, but if I type (without seeing) reboot and hit enter, it reboots. So I assume the single user mode is working.

What else can I try to 100% make sure it's my graphics card that failed and everything else is ok with Mac Pro? I already ordered a graphics card replacement but I wouldn't like to be surprised if the Mac Pro still doesn't boot when the card arrives. It won't boot from Apple Startup DVD either. Same thing happens, gray logo then kernel panic with jagged lines all across the shifted screen.

IMac :: 27" Wont's Boot Up / Takes A Very Long Time To Boot?

May 15, 2010

I have a 2 week old iMac 27", i7, 2tb Hard Drive, 16gb RM

In the second week the boot up times became very slow.

I would turn the machine on and get the chime within 5 seconds or so.

Then just a black/blank screen.

Eventually after about 10mins I would get a white screen then it would boot up normally.

Now the machine just doesn't get to the white screen. So I get the chime and then just darkness. It does sound like the machine is on (usual quiet imac whirring).

I've tried various key commands when I turn the machine on including pressing C with the install disk in the dvd drive and the alt, control, P, R pram reset.

I've also tried unplugging all the cables, leaving the machine for a minute and switching back on. I did manage to perform the PRAM reset once. I reset the machine and it booted fine.

But now when I switch it on just darkness.

I've called after sales and will try to get the machine replaced but in the meantime is there anything I could try that might make the machine work? I need to do a remix this weekend (deadline Monday) so really need to get it working.

Intel Mac :: Boot Partition Error Message - Mid 2010 I7 Will Not Boot Past The Apple Logo

Apr 8, 2012

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.

Power Mac G5 :: Cannot Boot From DVDs - Defaults To External FW Boot Drive With 10.3.x

Dec 20, 2007

This is bad and old, and full of lessons about backing up. Anyway, internal boot drive crashed a week ago, and internal optical drive is busted. New external LaCie dvd burner works fine, but all attempts to start up from Tiger, Leopard and Diskwarrior installation disks just end up back in OS10.3 on my external LaCie FW drive. I've tried many things: unplugged everything; switched external LaCie to USB (wouldn't boot), unplugged power from internal optical drive so Mac wouldn't look there first (somebody suggested that). Attempts to start up installers from mounted DVDs result in installer screen with restart button, which, when clicked on, results in... you guessed it... boot back to dreaded 10.3 system. Night owls and westcoasters, I am up for hours yet, pulling hair.

G5 Dual 2GHz
