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

IMac won't boot up after latest update. Any suggestions?

I just updated my software (the latest from apple), then my iMac won't boot again.

There you go. Your HDD is failing hence its not booting. You need reformat the HDD
To reformat, same steps: Boot to the install disc > get past the language selection > You will see Welcome to Blah Blah Blah > just hit continue > There should be something there called erase and install
BUT
1. if you are absolutely sure that Time machine has BACKED-UP all of your files then proceed above
2. If not, if you have another mac: connect it via firewire then google Target Disk mode. Basically you want to copy all your files from the damaged machine to the new mac to serve as a backup
3. if yo dont have another mac: get an external HDD, install Mac os X on it, boot to it then back up your files
to do this
a) Plug external HDD
b) Boot to the CD restart and hold C
c) Get past language selection and keep hitting continue
d) when it asks you where you want to install Mac os X > select the external HDD
e) once its installed. Restart the computer and hold "Option" key. You should now see your external HDD as one of the boot drives. Select that and you'll boot into it
f) once inside the external HDD OS, you will see the internal HDD(damaged drive)browse/navigate through it and start getting your important files

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 Mac OS 10.4.6 won't boot normally after new updates?

Pardon the fact that I'm a newbie...
It seems like a lot of people are posting about problems with the latest Mac OS updates. I installed some new updates Sunday night, and the system needed to be rebooted.
I was working, multitasking with Fire and Word, and in the process of printing a large Word document to my Acrobat printer, my system crashed. I could move the mouse, but there was no response from the keyboard or from my touch pad clicker. The only solution I found was to hard reboot.
Upon the reboot, there were no icons on my desktop, and neither my mouse button nor keyboard are functioning. However, I could move my mouse cursor.
I can boot in safe-mode, and all my files appear to be intact. I reboot from safe mode back to normal mode the problem in normal mode is the same. Clearly Mac OS isn't loading like it should.
I'm used to WindowsXP where multiple reboots usually solves the problem, but I gather thats not wise, and I really shouldn't be hard-rebooting.
Can anyone help me and give me some needed intuition with this? I'm a newbie with Mac, but pretty comfortable with Unix.
Thanks in advance!
MacBook Pro Mac OS X (10.4.6) 2.16 GHz Intel Core Duo, 2GB DDR2 SDRAM

Jake, I didn't have any problems with the updates.
I always run Disk Utilities permissions repair and verify disk before and after an OS or Security update. If verify disk reports an error, run Disk Utilities from the Installation Disc 1, specifically Repair Disk. (Some think running permissions repair is useless. I don't agree and have seen this clear up problems.)
If that doesn't do it, go back to Safe boot and check the startup items. A third-party startup item may be the problem.
Good luck. Don't want to rub it in, but I've been running since the MBP arrived on March 30 without any problems. But I've had glitches in the past, and probably will again in the future. That's life.

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)

Apply instructions here
https://support.apple.com/kb/HT2213
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.
See 10.5, 106. 10.7 OS X "overwrite" here

IMac won't boot up after latest update

Hi
I'm a newbie to this forum but any help would be greatly appreciated please
We've had our iMac for 2yrs now no issues but when I went to do the latest update today it's gone a bit weird!
I did the install and relaunch like I always do but when rebooting it got stuck on the white start up page with the apple logo and a circular timer
Ive rebooted it several times and performed a PRAM and SMC reset but still same issue. The fan started to run fast but the resets seem to have solved that?
Any ideas what's wrong and how to fix it please?
Thanks in advance

The reason Allan was asking what update is this will affect how it's handled. However without knowing I believe the most wise thing to do it take the machine into an Apple Store or AASP where they can help you. One of the most recent updates was a EFI update for 2011 iMacs. If your iMac is a 2011 machine (released after May 2011) and that is the update in question then the only recourse is taking it in as mentioned.
There are a couple of things you can try though, first is restart using the Install Disk or if you are on Lion restart and when you hear the startup tone hold down the Option Key. Then choose Disk Utilities and run Repair Disk Permissions, do this 2x. Then exit DU and try to restart normally. If that doesn't work then try rebooting in Safe Mode, this will clear some caches. It's possible one or more has become corrupt. If neither of these work then definetely take it in.
Finally please please please complete your profile, use Your Stuff in the upper right of this page then click Profile and complete. This is vital to helping you. At this point we know nothing about your system, what version of OS X, which iMac, etc...

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.

HT1222 iPhone 5s won't turn on after this update. Battery was at 98%, tried holding sleep & home button while plugged in, no good. Any ideas?

iPhone 5s won't turn on after this update. Battery was at 98%, tried holding sleep & home button while plugged in, no good. Any ideas?

P.S. I just noticed; when I hold the power and home button at the same time while it's plugged in as if I was going to restart it, my computer acts as if I'd plugged it in again (it makes the USB notification sound, itunes opens up again, I get the same "your iphone is in recovery mode" message, etc.), but that's the only response I've been able to get from pressing anything on the iphone. thanks again.

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?

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.

To open your domain file in Lion, Mountain Lion or Mavericks or to switch between multiple domain files Cyclosaurus has provided us with the following script that you can make into an Applescript application with AppleScript Editor. Open Script Editor, copy and paste the script below into Script Editor's window and save as an application.
do shell script"/usr/bin/defaults write com.apple.iWeb iWebDefaultsDocumentPath -boolean no"
delay 1
tell application "iWeb" to activate
You can download an already compiled version with this link: iWeb Switch Domain. Note: you may have to Control (right) - click on the app after uncompressing and select Open due to the Sandboxing feature of OS X. If you have problems with the app create your own with AppleScript Editor.
Just launch the application, find and select the domain file in your Home/Library/Application Support/iWeb folder that you want to open and it will open with iWeb. It modifies the iWeb preference file each time it's launched so one can switch between domain files.
WARNING: iWeb Switch Domain will overwrite an existing Domain.sites2 file if you select to create a new domain in the same folder. So rename your domain files once they've been created to something other than the default name.
NOTE: In Lion and Mountain Lion the Home/Library folder is now invisible. To make it permanently visible in Lion or Mt. Lion enter the following in the Terminal application window: chflags nohidden ~/Library and press the Return key - 10.7: Un-hide the User Library folder.

Problems after Battery Update 1.4

Has anyone noticed that since installing the Battery Update 1.4, their battery life has been reduced significantly? Prior to the patch I was getting a good several hours from a full charge, now I am lucky to get 1.5 hours.
Also, while the patch was meant to improve the Macs ability to +'maintain its charge when shut down and not used for an extended period'+, I immediately noticed the first night that I shut down with 3/4 battery and woke up the next morning with 1/4.
I have read of several people having issues with the battery not charging or taking a long time to charge - I haven't noticed if I am having this trouble as well.
Anyone??

My battery was great I never had to take my charger with me, but after Battery Update 1.4 my battery only lasts half as long now, and if I didn't use it for a week my battery was still 80%-90% now if I don't use it for a week I only get half an hour before I have to plug it in.
THIS UPDATE HAS CAUSED THE PROBLEMS THAT IT WAS MEANT TO FIX!
I only installed this update to be a good little consumer and have now ruined the performance of my macbook, I have tried to uninstall it and rollback to the previous version with out success.
Please help?
