IMac won't restart. Agreed to updates, rebooted and now only getting a white screen w/ flashing file folder w/ a questions mark?

I Agreed to recent updates, restarted my computer and all I am seeing is a white screen w/ a small flashing file folder icon w/ a question mark on it? I've already unplugged, turned on/off and disconnected/reconnected Apple airport?

Hi barnstorming7,
Thanks for using Apple Support Communities. Based on what you stated, it sounds like the computer boots to a flashing question mark. I would recommend that you read this article, it may be able to help the issue.
A flashing question mark or globe appears when you start your Mac - Apple Support

Hey, any help? My 24" iMac won't boot. I only get a white screen when turning on. It won't open in safe or recovery mode. Any suggestions?

If you can't boot from your installer DVD, then take it in for service.

My MacBook has a grey screen with a folder and a question mark in the middle what does this mean?

My MacBook has a grey screen with a folder and a question mark in the middle what does this mean?

It means a valid system cannot be found. You need to reinstall OS X.
If you have Snow Leopard:
Reinstall OS X without erasing the drive
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install Mac OS X 10.6.8 Update Combo v1.1.
If you have Lion or later:
Reinstall Lion, Mountain Lion, or Mavericks without erasing drive
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.
Reinstall Mountain Lion or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet
if possible because it is three times faster than wireless.

Macbook Pro Won't Boot After Starting Lion Install

2008 Macbook Pro 17" with Core 2 Dou processor.
Internal Disk has two Partitions
Downloaded Lion from App store and ran installer. Selected 2nd partition which is Mac OS Extended Journaled. (I was intending to do a clean install on this empty partition.)
Installs appears normal, goes to boot and hangs at the gray screen after the chime.
Verbose logging does not show anything obvious, no more info after identifying the network adaptors.
Booting with option key does not give option to boot to Snow Leopard partition.

My 13" MacBook Pro will not boot up - all I get is blank screen

The MacBook Pro is only 10 months old and is up to date on all OSX updates. I have been using it all day and suddenly this evening it just went to a blank screen and will not boot up. No fan, nothing. Nada.
I have tried the following:
checked magsafe and it is clean of any dirt
checked battery (pressed button on side of Macbook and got 6 green lights coming up)
There are no USB peripherals connected
tried pressing CMD+CNTRL+Start button and nothing happended
tried holding down start button for 30 seconds
The mac has not been dropped or had water on it.
Any other ideas?
Cheers

Which OS do you have...if it is Snow leopard then press shift while starting up, i.e., immediately after pressing power button
if the os is Lion or Mountain Lion press command+r to goto the restore thing and then disk utility to rectify your problem

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 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 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 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.

My Macbook Pro won't start up. All I get is a grey screen showing a grey folder bearing a question mark. Help please!

My Macbook Pro won't start up. All I get is a grey screen showing a grey folder bearing a question mark. Help please!

The folder with the question mark indicates that the machine is unable to find a bootable volume on startup. This is typically caused by one of three things:
1.) The internal HD has failed or is failing and needs to be replaced
2.) There is significant directory damage to the volume that requires repairing in order to boot
3.) Some other internal component failure between the HD and logic board
I'd ranked them in the order that is most common (from my personal experience). Boot to the OS X Recovery tool and attempt to repair the startup volume. If that fails or the drive is not detected it's usually a tell tale sign of a failed HD.

My MacBook Pro won't boot and apparently my HDD is locked

My MacBook Pro won't boot up. And it's says my HDD is locked when i try and reinstall OS. Help me please good people.

you want to check how many threads with same question first, and look in
Mac OS version forum that you have; and the notebook MacBook instead of the workstation forum for Mac Pro (non-laptop)
Not a lot of detail to go by with "won't boot" though.

My 2007 MacBook pro won't boot up beyond a White screen any ideas what to do?

My 2007 MacBook pro won't boot up beyond a White screen any ideas what to do?

Odd how this hasn't been archived yet.
I'm getting the same thing with my Macbook, but can't boot past the white screen. An Apple store in KS suggested I needed a new hard drive, but I've already put two in there and it's still doing the same thing. I really don't want to buy another motherboard like I had to a couple of years ago.
My choices are either buy a cheap drive to boot from and remove the current one to put into an external case, or save the money by not buying a new motherboard and putting it as a down payment toward a Mac mini.
