MBP won't boot up after Onyx maintenance

Did a complete automation on the latest version of Onyx for Lion since my mac was running a little slow.. And now my MBP doesn't boot at all! Just gets stuck on the apple logo. What do I do?

THere are a few things to try.
Start in safe mode
Reset PRAM
Hold down command-R to start in the lion recovery volume then run disk utility to repair the disk
Do an SMC reset.
You can try one of these methods then move on if that does not work.

My MBP won't boot anymore after "repair disk" and "repair disk permission"

My 2011 MBP 15 with Lion stopped working after I attempted to use Disk Utility to "repair disk" and "repair disk permission".
It was having weird issues before I attempted the repairs, it was freezing every few seconds no matter what I am doing, the whole thing would freeze with only the mouse movable. then after a few seconds it goes back to normal again. This happened after I downloaded and installed some updates from Apple. I don't know if the updates would cause this or it's something else.
In Disk Utility, "Repair Disk Permission" took 5 hours. While "Repair Disk" resulted in "Disk utility can't repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed up files".
Now when it boots, there's a loading bar under the Apple logo, it loads half way and shuts down itself.
I can still get into CMD+R Utilities though.
Any idea how I can extract the data out of the disk? I'm going to format and do a clean install.

A stopped loading bar is indicative of a failed firmware install that didn't complete, it's trying to install and is failing.
Do a PRAM reset

Reboot into Safe Mode, (shift key down) then reboot normally and see if that fixes the issue.

You may have to try to reinstall your firmware manually, you'll need another disk burning Mac
Find your exact firmware(s) here (or on Apple Downloads page)

Lastly it could be your boot drive is failing or something wrong happened with the update and accounting for all the to the other issues.
A OS X "overwrite" may solve the issue, may not.

MBP won't boot up after Battery update

I downloaded the update this afternoon on my MBP. I restarted my machine but it would not load OSX. It keeps going to grey screen with the apple logo and waits there for 6-7 minutes and restarts itself. It keeps doing this over and over. I've tried holding down the keys to reset memory, I've restarted it plugged in, and unplugged. I inserted Disc Warrior. Nothing has worked. Any ideas?

Try this
Boot holding down Apple/S and don't let go until you see scrolling text.
When that stops and you see a root#: prompt enter
fsck -fy
Let it run through all the checks and repairs.
If it fails first time, at any time, or finds and fixes a fault - run the command again and keep doing so (some fixes can take several passes) until it says "Appears to be OK" then enter
reboot

MBP won't boot - "GRUB_" - tried installing ubuntu on an external drive

so i tried installing ubuntu netbook remix onto an external drive, and upon restarting my MBP won't boot to my internal HDD, once it displayed "GRUB_" with a blinking cursor, but is otherwise unresponsive.
now i just get the folder with the ? on it.
I've run disk util, repair permission, repair disk and still no luck.
i can boot the MBP into target disk mode and see the HDD on my other system and all appears to be good, and if i boot to the install dvd, the HDD shows up under the "startup disk" menu, but it just doesn't boot.
any thoughts on how to fix this?

So I have an imac that I have had for about 3yrs. About several months ago, it started acting a little strange, it wouldnt pick up the mouse or the keyboard at times even thought they were plugged in properly to the usb port, sometimes both would work sometimes one or the other would work and other times they worked fine. About a month or 2 ago, I went to turn my imac on and it got to the screen where the little circular icon pops up implying it is loading, stayed that way for 2-3min then turned of and turned itself back on and did the same thing, made the apple sound got to the load screen turned of after 2-3min then turned back on, it has been doing that for the past month. What do I do?

My 2006 iMac running Snow Leopard won't boot even after erasing and re-installing Snow Leopard (via my MacBookPro), either from the HD or DVD drive. Can't get it to run Hardware Test. Disk Utility says disk OK - files are there. What can I do?

My 2006 iMac running Snow Leopard won't boot even after erasing and re-installing Snow Leopard. I erased and re-installed by putting the iMac in Target Disk mode and usin my MacBookPro as the host. But after numerous attempts I still can't get it to boot either from the HD or DVD drive. I just get the white screen after the wheel stops spinning. I can't get it to run Hardware Test - just get the white screen. If I use Disk Utility via my MBP it says the disk appears OK. All the Snow Leopad files appear to have been installed. What can I do?

Reet the SMC and the PRAM

Perhaps you installed the wrong version OS X onto the iMac, you can't use the disk from another Mac.
clean the disk.
If it's not working then use this method to create a bootable 10.6 USB from the iMac machine specific 10.6 disk or the 10.6.3 retail disk on your other Mac, use it to boot the iMac with.

Mac OSx won't boot up after update to 10.6.7?

Mac OSx won't boot up after update to 10.6.7?

Hi Mike
This is called a kernel panic, similar to s 'blue screen of death' on Windows. When you say you reinstalled 3 times, do you mean the OS or the Update?
When does this kernel panic appear? You may have a hardware issue if it's happening on boot.

MBP won't boot after update!

I've got a late 2006 model. I'm hoping my problem isn't related to a hardware failure. I left it on during the day, came home, the fan was running hard and it was really hot. Performance was slow, but everything worked.
it was asking me to restart for the latest update anyway and I'd been putting it off for a day or two, so I decided to restart and let it go through with that.
But now, it won't boot. It starts up with the grey screen, a bar starts filling at the bottom, gets maybe 1/10th of the way, blinks out then another bar appears, starts filling, gets a little further, then the machine shuts off. Exact same process every time I start it.
I'm not really familiar with what my options are here.

I've got about 300 GB of space, so that shouldn't be the issue.
No, that certainly isn't the issue! Just had to make sure.
If it's not a hardware issue which happened to coincide with the update, the update may be corrupted or not completed. If either is the case, and you have another Mac available, you can try downloading the update from Apple Support Downloads, booting the MBP into FireWire Target Disk Mode (if it will cooperate), and trying to install the update that way. I have not tried this method, so cannot say if it will work or not, but I would try it prior to the alternative, which is to reinstall the OS (or, better yet, clone a backup to the MBP).

Computer won't boot up after installing SIIG card

Hey Everyone,
I having problems with my SIIG FireWire 2-Port PCIe DV card that I've installed into my PowerMac G5 Quad. With the card installed the computer will not boot up, which is the same thing that happened with my previous two models of the card. I installed a new card yesterday and it worked fine all day, but after shutting the computer down for the night and then restarting it in the morning I am experiencing the same problems. The light on the front of the computer turns on, but the screen does not, and after about a minute a loud fan noise comes one. I have the card installed in Slot 2. In Slot 1 I have a ProTools HD card and in Slot 3 I have an AJA Kona LHE card. Even with all of the cards removed the computer still does not boot up. Anyone seen this problem before? Any help or information anybody can offer would be greatly appreciated.
PowerMac G5 Quad Mac OS X (10.4.8)

Hi, I had the same problem with my dual core G5.
I installed the card and my computer won't boot up. The screen stays gray and the fan keeps spinning.
I contacted SIIG and they said the card is defective, which, I doubt it is.
I then returned it for a refund.

New Unibody MBP won't boot from DVD or external drive, just loops

Hey
We bought a new Unibody MBP on Monday, and loaned it to our CTO for a presentation. Having got it back from him now I wanted to nuke the installation and put a fresh copy of leopard on it, so I dropped the DVD in the drive, powered down, and booted holding the "C" key.
I get the chime, screen lights up, thinks for a bit, and if you use your imagination you can almost hear the DVD spin up. Then the screen goes black, lights up, chime, thinks a bit, goes black, lights up, chime and so on
I've tried booting from an external bootable clone I created with CCC (firewire external HDD), and same symptoms.
I even tried swapping in a hard drive that I know has a working bootable copy of Leopard on it, and then all I get is the eternal cycle, without pressing any keys on startup.
I also tried holding down the Option (Alt) key on boot to get the boot device selector. This correctly identifies the various boot devices - the DVD, on-board HDD and external firewire drive (if connected), and lets you select them, tries to boot, thinks, black screen, screen lights up, chime, repeat cycle endlessly until extremely frustrated.
Is there a known cure for this or am I doomed to take the thing back to the Apple store on Monday?
Thanks
Konrad

That is not the reason it didn't work. Here is the actual clarity:
*A retail Leopard DVD should be able to boot a new Macbook Pro unibody.*
So you are saying even if the driver for the controller on which the DVD drive sits is not available in the Leopard DVD you are using because the hardware was not manufactured at the time the Leopard release on the DVD was made, the OS should magically just boot? How is that possible? Unibody MacBook Pros have entirely NEW AHCI chipset - for which there won't be any drivers on the older Leopard DVD and as such the DVD wont be detected once the OS on the DVD loads. In cases where the chipset used is same (as in previous generations of MBP) it will boot.
The key difference here is that if you used an older version, some new hardware may not be supported - however, the computer *should still boot from the DVD*, which is the subject of this discussion.
The OP said that his computer boots from the DVD that came with the computer - just not with the old retail Leopard DVD. Also - what should happen if the new hardware happens to be the controller on which the DVD drive is sitting? How will it be able to read the DVD? What about the graphics card? If the drivers on the old leopard disk do not recognize the new graphics card - how is the OS going to display on screen?
On my way home, I stopped at a Mac store and asked them to test this. They successfully booted a new Macbook Pro unibody from an older Leopard DVD. And this is why Apple is replacing my computer, because it is a hardware issue, not a software one.
Again - you fail to understand that whether or not the old DVD boots on a new machine all depends on how much hardware has changed and what hardware has changed. It may boot on some generation of machine because the basic chipset and graphics did not change or were handled generically by the drivers on the older DVD but it may totally refuse to boot on new gen machine which has totally different / incompatible hardware.
So your claim that any old Leopard DVD must continue to boot on any new machine is not really technically explainable.

MacBook Pro won't boot up after Lion upgrade

I upgraded my 13" macbook pro to lion last night. I watched some movies until the battiery died. Now it won't boot up. Indicator light does not come on and it makes no noise. Battery indicator says it's full. Any suggestions?

MBP's are very finicky about RAM. Most of us here will recommend Crucial or OWC as the best source. If I were you I'd put the original RAM back in and see if the problem goes away. If so, return what you just bought and buy from one of the vendors I mentioned.

My mbp won't power up after update.

after running an app store update, (Xcode) my mbp won't power up and the battery lights are showing flat even though it was on charge over night.
the update was taking a long time, and it had a message saying something like deleting old files.
i went to bed and left it over night.
when i went back this mornng it had powered down, and the drained the battery even though it was plugged in.
now i can not power up, and i have tried the smc reset.
please help.
many thanks.

This is the standard Apple support article for your situation. If you cannot try another adapter to try, I suspect a trip to an Apple store genius bar is in your future.

MBP won't boot. Gray screen, apple logo.

As above, my 2.4 Macbook Pro, won't boot past the gray Apple logo and that spinning circle.
Holding C doesn't allow it to boot from CD either, for Leopard/Tiger OR Disk Warrior!
Holding alt allows the start up menu, but then spits the CD out and only shows the Macintosh HD which obviously wont boot!
HELP!

Won't boot anymore after nvidia-xconfig

Hey Guys,
Got a problem with my Arch Linux here, hope you can help.
Today I tried to install the official Nvidia Driver and BumbleBee following along the great Wiki on this topic.
Everything worked just fine and I also could run optirun gfxgear or somemthing like this.
I wanted to switch to the Nvidia Settings in the settings menu and it told me to configure my xconfig and restart x so I typed nvidia-xconfig in the terminal and it gave me an success output.
I restarted my system and now it hangs on the graphical thing I think. It won't boot anymore.
Hope you can help me out.
Thanks alot
Edit: My Nvidia Card is a Nvidia GT 740M if this matters
Last edited by Whitz (2015-02-09 11:02:41)

No, I have a laptop with 2 graphic cards an intel hd4000 and a nvidia gt 740m.
I ran the Arch Linux installation well until I tried to get the nvidia gt working with bumblebee.
I followed the wiki of the bumblebee topic and it worked well. I wanted to switch into the nvidia settings and it told me my x isnt configured properly and I should type nvidia-xconfig and restart X.
After the restart it won't boot to the graphical interface anymore.
Hope this cleared up the things
Also I dont get any errors but it just wont load..

MBP won't boot recovery USB drive, need help

HDD failed on 15" mid2009 MacBook Pro, purchased a Seagate 1TB hybrid drive (SSHD) to replace it with. Went to boot to USB recovery drive with OS X 10.8 using option/alt on boot and would only get the folder with flashing question mark. Tried command+R also. Tried different USB ports. Tried with HDD pulled out. The USB recovery drive does work because we were able to boot to it from a different MBP, and verified the files on it with Disk Utility. Just can't get any kind of recovery options or anything on this Mac with replaced HDD. Need help. Never encountered anything like this, can't find anything like it online, and none of my coworkers can figure it out. We've all been working comps for yrs, one even an ex apple-tech. Thanks for any suggestions!!

Sorry - missed that part about having used both USB ports...
Since you've verified that the USB thumb drive works on another Mac, and that it won't boot whilst holding down the option key, I would advise taking your machine to an Apple Store or an AASP to have them diagnose your machine (which will be free). They, too, should have USB sticks that they can use to test the machine.
Good luck,
Clinton
