MacBook Pro won't restart after Mavericks update

I recently installed the new Mavericks update on my MacBook Pro and after downloading Pages, Keynote etc. I had to restart. When I try to restart however, the Apple logo appears with the progress bar but as soon as the bar is full it switches off.

Hello SerenAlyx
Check out the articles below to go over troubleshooting the issue of the grey bar when you are starting up your Mac. It will go over starting up in Safe mode as well as booting to your Recovery Disk to maybe reinstall OS X Mavericks.

MacBook Pro won't restart after OS update

Was prompted last night to do an OS Software update. I was running 10.8.3. I started the update and had to run out. When I returned, the screen said i needed to restart my computer to install the updates. I did, and now I can't restart/reboot past the Apple Logo and progress bar which gets to about 1/6th in progress. The computer just shuts down?? Need help please. Thanks!

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

MacBook Pro Won't Boot after Firmware Update

So I just upgraded to a MacBook Pro which came in the mail yesterday. I removed the Apple-installed HD and swapped it out for a bigger, faster HD. I installed OS X from scratch, imported everything from my Time Machine backup during the Setup Assistant, and then started installing updates. Everything was running swimmingly until the last updates.
What happened is when I rebooted my MacBook Pro and logged in after a series of updates, I got presented with both a Bluetooth update and a Firmware update at the same time. Both required a restart so I thought I would kill two birds with one stone. I installed the Bluetooth update, and then when it asked to reset I installed the Firmware update instead. However, the firmware update didn't behave as advertised because instead of shutting the MacBook Pro completely down, it restarted and then started installing the firmware update.
Ever since the firmware update (which I think installed correctly but don't know how to verify), I cannot boot my MacBook Pro. Using the OS X install DVD I can view my firmware version using System Profiler, and the number it is reporting is MBP53.00A.B03.
I have tried booting in verbose mode to try and get a feel for the problem, and it eventually hangs on an infinite loop saying something about not being able to find something on disk0s2.
I also thought I would fix the problem by doing an Archive and Install, but it quit at the very beginning of installing with the error "unknown error".
Also I thought I would format the disk with Disk Utility and then try installing again, but Disk Utility reports that it in unable to unmount the volume.
Any help you can provide would be greatly appreciated. Thanks!
-- Update --
Remember how I'm unable to unmount the drive? I force unmounted it and then used Disk Utility to repair the volume, but still no luck.
I think the key to the problem is this new HD I put in runs at 3 Gbps. I think I read somewhere that the new MacBook Pro's don't support that.
I think next I should try swapping out the new HD in my MacBook Pro with the one it originally came with. What do you think?

I, too, have a brand new MBP 15" that I put an Intel X25 in. At the 1.5 (Prior to Firmware Update) setting, it worked fine. I rant the Firmware Update, all looked fine, but the drive is no longer able to be seen.
Flash the PRAM, per other suggestions to no avail. Boot off of the DVD and disk utility nor Profiler sees the drive.
Replace the drive with the stock that came with the MBP (which I had never even used) and it works.
Put the Intel X25 into a Windows machine and it works fine. Reformatted it (in windows) and put it back into my MBP. Still not able to see it (from the Disk utility after booting off the DVD).
Intel's firmware for the drive says its up-to-date (new drive) and if I attempt to "re-run" the Mac Firmware Update, it says that the machine is already up-to-date.
Seems odd that it worked before an now it doesn't. Also seems odd that the X25 works in other machines. And that my MBP works just fine with the stock Hitachi 7200 320GB drive.
Ideas? Intel says to call Apple Support. Not sure what I can say to them.

MacBook Pro won't reboot after Lion update

I have updated my new MacBook Pro (2.3GHz I7 15"), and everything seemed to be working fine. Something was chugging away at the system resources when I was away from my computer and when I came back, I decided to reboot the system.
Now all that will happen is boot up to the Apple logo and spin the little grey circle, for an hour! I don't know what to do, help my computer is useless!
I have booted into the recovery partition and repaired permissions, but it did not help. Anyone have any ideas?

Lion only runs on Intel based systems which have to be core2duo. with a minimum of 2GB RAM.
If these is given on your system, in most cases it comes from running old PPC-Applications which are not longer supported since Lion.
Try to start your MB in "Safe Mode" by holding option key (alt) imediately after first chime and disable / delete this applications.

MacBook Pro Fan running fast after Mavericks update

Hello All! I have a 2009 MacBook Pro 13 inch and I have noticed that after I updated to Mavericks my fan has been running really fast and my computer getting warmer than normal. It's always on a table so there is nothing blocking the port in the rear. Any ideas on how to fix this?

Hey emilyiow,
Thanks for the question. I understand that you are experiencing issues with your MacBook Pro in relation to the fans. Sometimes, this symptom can indicate that the SMC needs to be reset. For more information and instructions on how to do so, check out this resource:
Intel-based Macs: Resetting the System Management Controller (SMC) - Apple Support
http://support.apple.com/en-us/ht3964
After performing normal troubleshooting, these symptoms may indicate that an SMC reset could be necessary.
Fans
- The computer's fans run at high speed although the computer is not experiencing heavy usage and is properly ventilated.
Additional information:
Using Apple Hardware Test - Apple Support
http://support.apple.com/en-us/HT201257
What to do if you get an error in AHT
Confirm that the power adapter is connected if you're using a Mac notebook.
Confirm that all external devices are disconnected from your computer.
Record any error code given so that you can give the information to a Mac Genius, Apple Authorized Service Provider, or Apple Technical Support Specialist.
Thanks,

Macbook pro won't restart after time machine install on new hard drive

I installed a new 500 GB HD on my 13-inch mid 2010 Macbook Pro (since the original crashed). I successfully connected to the Disk Utility via the internet connection and started recovery from a recent Time Machine backup....but, the computer will not restart. It's been stuck in the grey screen with the Apple logo and rotating status bar all night. I shut it down and restarted, but it won't go past the grey screen state. I can't find any answers on the Support Page. Help. Any one else have this issue? Should I have first installed the Lion OS X first and then restored from the Time Machine backup?
Also, wondering if all my programs (2011 ILife & IWork and Microsoft Office) will be reinstalled with the back up? (I can't find my installation disks for ILife and IWork :-()

Time machine is easy to set up and theoreticaly recover from. There have been reports of problems when a different disk or computer is used.
https://discussions.apple.com/search.jspa?peopleEnabled=true&userID=&containerTy pe=&container=&spotlight=true&q=time+machine
For future reference you may wish to learn about and use cloning of the HDD. I use both CCC and SD to do this and consider it to be the most reliable way to back up and recover.

Help - Macbook Pro won't start after running update

I just checked the FAQs here and ran several searches and have not found an answer to my problem. I sure hope someone here can help.
Today I installed the big batch of updates Apple released recently (I think it was on July 31) on my 2.4 GHz Macbook Pro. When I turned it on, I was told there was one last update that required me to turn off the machine and then hold down the power button.
I did, and the machine started to come on, but I guess I held the button down a little too long. Now the machine won't turn on. Everytime I press the button, I hear the same sound I always get when I turn on my machine, except that now the sound just goes on and on and on, and the MBP never actually boots up.
I wish I could remember the exact name of the update. I think it might be the EFI Firmware Update 1.2 that's described at http://www.apple.com/support/downloads/macbookproefifirmwareupdate12.html. That scares me because the words "Important: Do not interrupt the update" suggest things can go badly if the update doesn't go right the first time.
Any advice as to what I should do?

That sounds like an interrupted firmware update. And Macs with interrupted firmware updates are very unhappy Macs!
You will need to restore your firmware to it's original state, then reapply the update. For this, you'll need to create a Firmware Restoration CD.
See this page:
http://docs.info.apple.com/article.html?artnum=303469
Here's one of the more important sections of the page: +"If your computer is already in this state, you'll need to download the software and create the CD on another Macintosh computer, or you can take your computer to an Apple Store or Apple Authorized Service Provider to restore your firmware. This CD can be created on both PowerPC- and Intel-based Macintosh computers."+
You might be better off just taking it in to an Apple Store.
Ps. When you get a chance, you might want to update OS information in your forum settings - I'm pretty sure you're not running 10.3.8 Panther on your MBP!

MacBook Pro won't restart after installing Lion

I have a late 2010 model MacBook Pro that I upgraded to Lion about a year ago. Ever since, I have not been able to "re-start" my computer and have to manually switch the computer off. Because of this, I cannot install firmware updates. Do I need to revert back to Snow Leopard or is there another way to fix this issue?
Thanks.

If you have more than one user account, these instructions must be carried out as an administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Step 1
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time when you had the problem. Select the messages logged before the boot, while the system was unresponsive or was failing to shut down. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V). Please include the BOOT_TIME message at the end of the log extract.
If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message.
When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some private information, such as your name, may appear in the log. Anonymize before posting.
Step 2
Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the entire contents of the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post shutdownStall, spin, or hang logs — they're very long and not helpful.

MacBook Pro won't start after I completed my first backup using TimeMachine

Hello,
My MacBook Pro won't restart after I did my first TimeMachine backup. I tried in SafeMode but no luck. My MacBook Pro is a 2009 early version running Snow Leopard. Please help.
Thanks,
Serey

I have managed to get into my computer through the OS X install disk but now my wi fi hardware is gone. Ie no airport.
When I try to re install the airport extreme wi fi base station software it tells me it can't be installed as this version of Mac OS X (Lion) on is volume is not supported.
Not even an Ethernet cable gets me on line. In system preferences when I do a network diagnostic all I get is the spinning disk. Again, any ideas how to get around this?
Thanks

MacBook Pro won't boot after trying to install 10.7.3 update. Start up stalls at Apple logo and spinning gear.

MacBook Pro won't boot after trying to install 10.7.3 update. Start up stalls at Apple logo and spinning gear. Computer won't even start in safe mode.

My daughter's MacBook Pro was doing exactly the same thing. I don't know if it had anything to do with the latest update. She called me about a week ago saying that her MacBook began running slower by the day . She then called me Friday and told me that it wouldn't get past the gray screen and the gear just kept on spinning. I did everything I could over the phone including Safe mode which it wouldn't go into and thought maybe it was the hard drive. She took it to the Apple store. Originally, they also thought it was the hard drive. It ended up being a corrupted operating system (Lion). Apple genius simply re-installed Lion and she's back up and running. Good thing she backed up right before it crapped out. She'll be restoring everything tonight. Don't know if re-installing Lion will help your situation, but it did the trick for my daughter.

WHAT??? Now that's a disappointment! I was sure the all-seeing, all-knowing Prof. Kappy would instantly discover the problem thru time and space....
Ok, back to the issue at hand, the Prof. is right. In none of the OP's participation, nor in any of his choir of followers save mommy power is there the least hint of what Apple product is failing. While y'all get a move on and disgorge the details, may want to try a Safe Boot. Hold down the Shift key prior to the startup chime and wait awhile. IF it starts, then it means you have some third-party software that's causing the problem. Else there's a strong probability a complete reinstall will occur in your near future.
In the future and in spite of what some purists may say, be sure to service the system disk BEFORE patching. By "service" I mean booting up the Mac using your Install DVD (Snow Leopard or priors) or booting in Recovery Mode (Command R, in the Lions and successors), running the Disk Utility found in that mode and doing a Repair Disk and Repair Disk Permissions. Until NO errors show up. Cause patching up an already damaged system will only make things worse.
