MacBook Pro won't boot up after interruption of update

I interrupted the installation for the OS X Mountain Lion v10.8.2 and now my MacBook Pro will not boot up. Any suggestions besides calling Apple support or going to the store?

Hi,
I am having the same problem with my Macbook Pro. Did you manage to find a solution to this problem?

MacBook Pro won't boot up after updating to Lion

I just updated my MacBook Pro to Lion. After install restart the computer is stuck on the white screen with the apple logo and spinning wheel. I manually restarted it after 1 hour but that didn't solve the issue. What do I do? Any advice would be greatly appriciated.

That sounds like the case. Good Luck.
check this link:
http://lmgtfy.com/?q=Lion+boot+disk
there is a ton of information, step by step. I am sure there is probably something here in these forumns on creating the boot disk.
Again I would start with a clean install of Lion off of the boot disk you create.
FYI I started with Snow Leopard time machine backups updated, then cloned my existing drive to a FW drive before installing. During the work day and in IT, It was a savior to target boot from the firewire drive to address employee needs when I was having Lion lock up issues from the initial install.
Wipe and install clean so far so good. No lock ups. And USB flash install was super fast. Then brought my apps over, or re-installed. This way everything was clean.

Macbook Pro won't boot OSX after Yosemite upgrade 10.10.3

I downloaded the update to 10.10.3 this morning before driving my daughter to daycare. When I came back, my Macbook Pro had rebooted into Windows 7 (Boot Camp). I restarted it by telling it to reboot to OSX, but it boots Windows again. If I turn it off completely, and then turn it on again, there's no chime... just a black screen for about 30 seconds, followed by "Starting Windows". I'm about to reboot to try resetting NVRAM and SMC, but I don't know if that's going to work without the chime...
I really need OSX to get going, so any help appreciated.

If you don't already have a current backup, back up all data, then reinstall the OS.* You don't need to erase the startup volume, and you won't need the backup unless something goes wrong. If the system was upgraded from an older version of OS X, you may need the Apple ID and password you used.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
If you installed the Java runtime distributed by Apple and still need it, you'll have to reinstall it. The same goes for Xcode. All other data will be preserved.
*The linked support article refers to OS X 10.10 ("Yosemite"), but the procedure is the same for OS X 10.7 ("Lion") and later.

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 Macbook Pro won't shut down after installing Lion. Anyone have a suggestion to fix this?

Just installed Lion, and it won't shutdown!
The only way it'll shut down is if it drains the battery.
Help!

Lots of other people are complaining about their Macs taking long times to shutdown. Some solved it by reinstalling Lion from scratch (without using a Time Machine backup and simply copying all their files on to the new install).
Others discovered old software that is no longer compatible with Lion (I found Mac The Ripper in mine, plus many others on day 1). I uninstalled some apps using App Cleaner (google it, it's free and it's awesome).
I was having a hard time shutting down my macbook pro, now it's back to normal.
Try finding applications that are not compatible with Lion. Their icons should be greyed out and with a diagonal line crossing it. Make sure you erase these applications and library related files, which is very simple if you use App Cleaner. And make sure you look into sub-folders inside the Applications folder, as I missed a couple because they were not immediately visible.
Hope it helps. If it does, let us know.

Macbook Pro won't shut down after installing Yosemite

Hi,
I just finished installing Yosemite on my Macbook Pro. It's fairly new, the last version with a DVD drive but without retina display (I bought it in May 2014 and it's my first Mac).
I installed Yosemite, updated all my applications from the App Store and tried to shut it down from the Finder but the screen just freezes on a black screen wth the pointer showing and then I to shut it down using the power button which I hate doing.
I turned on FireVault after set up and that is busy encrypting could that be causing this? I did check online and it says you can put your Mac to sleep or shut it down while this is happening, but I haven't been able to. Any tips would be great.

I had the same problem and just fixed it.
What I did:
- Launch Disk Utility > Select Macintosh HD > Verify Disk
Let the Verify run until it's done
- If you are seeing any error try the Repair disk
It's possible you need to restart (holding cmd+r while restarting)
- Next I did a verify disk permissions and a repair disk permissions
- reboot
After this the shutdown issue was gone!
Hope this solves your problem as well.

'09 MacBook Pro won't start up after installing new hard drive and restoring from an external hard drive.

I am in the process of replacing my hard drive and have run into a problem. I reinstalled OSX 10.6.3 using a DVD I bought off Amazon. That went well and I then restored my hard drive using an external and Time Machine.
After that, things still looked good but I couldn't log in to my user (and access my MacBook) because my password wasn't working even though my hint was correct. Yes, I am POSITIVE my password was correct; I even tried a couple other passwords to humor myself. I then gave up and decided to restart the computer.
Now my MacBook won't start up at all. It goes o a gray screen with a still loading symbol for a couple minutes and then goes to a solid light blue screen. I've tried starting up while holding command+R and I tied holding just command and neither worked.
Did I install the wrong OSX because I didn't use the same DVD that came with the laptop? Is there something wrong with my hard drive already?
Please help =[

You probably bought the wrong RAM that has different pin assignments, so it won't fit in the slot. Return it.
I bought 4GB Memory online for my MacBook, so I could get it to run twice as fast.
Doubling the memory does not make your computer run twice as fast.

MacBook Pro won't turn on after installing system updates

So my little "system update" reminder kept bouncing at me last night so I wnt ahead and told it to install updates and went to sleep only to find, my beloved MBP will not turn on this morning.
If I hold the power button, it surely SOUNDS as if it wants to turn on, but the second I let go...nothing, zip, nada.
Any suggestions?

Not the right time to update and go to sleep. What updates? How much free space was on the hard drive?
Try inserting the OS installer disk in the optical drive and powering up holding down the c key.

Macbook pro won't boot after installing update 10.9.3

macbook pro won't boot after installing update 10.9.3

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 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.

Macbook pro won't boot, stuck on white apple screen

Noticed today, that my macbook pro won't boot . It gets to the white apple screen with the spinner under the apple logo. It stays like this for a long time without doing anything except spinning.
I've powered down and tried to boot up several times.
I have boot camp and windows on my mac and when the white screen appears, I can press Option to bring up which hard drive and the Windows partition will load without any problems.

Exacty what happens when you try to boot up from the disc that came with your computer? Are you holding down the c key? Have you tried holding down the "option key?" Are you able to run the Hardware Test - Intel-based Macs: Using Apple Hardware Test
Shut down your computer and disconnect all peripherals (keyboard & mouse if pertinent) from your computer. Now reboot.
If the Mac starts up normally, shut it down again and then plug in one of the peripherals (keyboard or mouse first) and start up your computer again. If it does so successfully repeat the process, adding one peripheral at a time until your Mac acts up. At that point, disconnect the last peripheral you added, reboot your Mac and search the peripheral vendor's website for an updated driver.
If no driver exists or the problem remain after installing the new driver, try a different cable or a different port on your Mac.
If none of the above works, again disconnect all peripherals from your Mac, hold down the "shift" key to start up in "Safe Boot" mode.
If the Mac starts up correctly, restart without pressing the "shift" key.
If your computer still does not start up properly, shut it down and restart it while holding down the Apple+Option-P-R keys; keep holding "all 4 keys" down until you hear the startup sound "twice."
If none of the above work Disconnect all peripherals from your computer. Boot from your install disc & run Repair Disk from the utility menu. To use the Install Mac OS X disc, insert the disc, and restart your computer while holding down the C key as it starts up.
Select your language.
Once on the desktop, select Utility in the menu bar.
Select Disk Utility.
Select the disk or volume in the list of disks and volumes, and then click First Aid.
Click Repair Disk.
(If Disk Utility cannot repair, you will need a stronger utility (3rd party) - Diskwarrior or Techtool PRO)
Restart your computer when done.
Repair permissions after you reach the desktop-http://docs.info.apple.com/article.html?artnum=25751 and restart your computer.
Remove any 3rd party ram.
Reinstall Lion - This will install a "fresh" copy of Lion without archiving old system files but leaves the rest of your files in place.
If your computer is still under warranty or you have Apple Care, take full advantage of it by letting tech support deal with your problems. It's what you're paying them for.
Out of warranty - take the computer to an Apple store or an AASP. Whichever is more convenient for you.

Macbook pro won't boot - how do I retrieve emails?

Hey guys
I've got a common problem that my Macbook pro won't boot. Sometimes I get stuck on the grey screen with spinning wheel, sometimes on the blue screen with spinning wheel
I've scoured the internet on another machine and tried every trick I can find with the MacBook Pro including
Disk / Permissions repair from install disk (says the HD is fine)
PRAM
Single User
Soft
It seems like my only option at the moment is an Install and Archive. I can mount the MacBook Pro on another machine with a firewire and remove files and backed up a lot on a hard drive before it died
What I am worried about is how to retrieve some emails from the machine that only exist locally because I have deleted them from the server
Is there a way of doing that?
Would Migration Assistant work?
If anyone could help me with this or suggest any other methods for bring my machine out of a coma I'd really appreciate it

Try a different adapter. If you don't have access to a known-good adapter any other way, make a Genius Bar appointment at an Apple Store.

MacBook pro won't boot up Keeps turning off

MacBook pro won't boot up. When power button pressed the white screen w apple comes on w progress bar but shuts off before bar completed. If I move cursor or hit buttons it boots but will turn off if cursor stops Moving or stop pushing buttons. Just started happening. Ran hardware test and all shows ok. Any ideas??

Thanks for all the help; however, I still continue to have problems booting off of any other media.
I've tried the Apple CD w/ no success - I made an image of the apple cd and restored it to a USB drive, and it won't boot. I've tested both methods on another mac, and both options boot fine.
I'm going with my last restort here and am going to install OSX on a portable USB HD, and try to boot off of that (no clue if it will work given the outcomes of the other things I have tried). From there I'm going to backup the HD, and try DW as suggested.
Any thoughts as to why the mac refuses to boot off of any other media? It always boots halfway and then tells me I need to shutdown my mac.
Thanks again,

MacBook Pro won't boot at start. I get a white screen with a blinking folder with a question mark in the middle. Any ideas?
