My mackbook air won't start it shows the gray startup screen with a loading bar then just shuts down again how do I fix this?

All it displays is the gray loading bar like it is updating then it gets a quarter of the way through at which point the wait circle appears and the computer shuts down. I need to get my computer working for college again anyone have any suggestions. I did the hardware test an it shows me a -1007D

You probably have some type of hardware failure. The only people that can fix hardware failures are Apple or an authorized Apple repair center by replacing the part or parts that have failed. So you'll need to take the system into Apple to be diagnosed and repaired.

When I log onto my macbook, my user account isn't showing up. All that shows up is a gray screen with only two boxes saying "Name" and "Password". How do I fix this?

There was one time where my wi-fi wasn't connecting so I tried to turn it back on. A window popped up but I had alrdy clicked enter before I read it, but it said something like "...will change settings, is that okay...?" And then wi-fi still would not connect. So I tried restarting my computer, but when it turned on, my user account did not show up and all there was on the screen was two boxes that asked for name and password. I was the only person using my macbook so I never set up a password for it. Has anyone had this problem? How do I fix this?

Since I'm not in front of your computer I can't tell what you see - I can only guess and give a hint. So once again, if the disk name on your Mac is "Macintosh HD", when you boot in Recovery Mode, and start up the Terminal in "Utilities" menu, and then type in the command:
    df -k
you should see a list of "volumes" - one of which is named "/Volumes/Macintosh HD" (but yours could be anything) and in that folder there is another folder called "Users" and in that folder is the names of the home directories of the user accounts (and the names that you can enter into the login screen) that you are looking for. So if you are not familiar with using the Terminal you should say so and I can give more details. But assuming you're OK with typing in commands to theTerminal this is what I would try:
    ls -l /Volumes/Macintosh HD/Users
and you should see something like the following (my disk name is "Yosemite" so I typed "ls -l /Volumes/Yosemite/Users")
ML9Book:~ xxxx$ ls -l /Volumes/Yosemite/Users
total 0
drwxr-xr-x+ 11 Guest      _guest   374 Oct 25 19:23 Guest
drwxr-xr-x+ 33 Jack       staff   1122 Oct 24 10:49 Jack
drwxrwxrwt   13 root       wheel    442 Dec 27 2013 Shared
drwxr-xr-x+ 38 admin      staff   1292 Oct 25 16:59 admin
drwxr-xr-x+ 15 x13        staff    510 Oct 23 22:41 x13
drwxr-xr-x+ 12 514        staff    408 Oct 23 12:24 x14
So now reboot your mac into normal mode - and you will see the login screen with the two empty boxes.
So the above output tells me that there are 3 users - Jack, x13 and x14 (there is always a Shared user and there might or might not be a Guest user since it depends on how your setup was setup) - and these 3 are the names that I could try and enter into the login screen (in the top or first box). You can try no password, but I don't think you can create accounts without passwords, so this will likely fail. In that case you need to reboot in recovery mode and run the Terminal command again (from the Utilities menu) and do a resetpassword command. Another window will pop up and from there you select the Volume (in my case I selected the Yosemite volume - in your case you would select the "Macintosh HD" if that is what your volume name is). Then select the user account you want to reset the password from the drop-down list of user accounts (it will show you the long and short names, and the short name is what was in the listing above from the "ls -l" command), then enter the new password in the indicated box, and then enter it again in the next box, to make sure you didn't make a typo, and enter a password hint in the last box (optional). Then click the "Save" button and you will see another dialog box pop up telling you that the password was changed but not the Keychain password (hopefully you remember this one) - click the OK button then reboot back in normal mode (click on the Apple logo in the top left corner of the screen and click on Restart).
Does this help?

Created slide show in iPhoto, but with new version music no longer will play. When I click on fit slideshow to music, iPhoto shuts down. How can I fix this.

I created a slideshow in a previous version of iPhoto. Since updating software the music in my slide show no longer plays. How do I fix this? If I select fit slideshow to music, the application will shutdown and the error file is sent and have to reopen iPhoto.

I reorganized iTunes music library and it works.

Firefox has spontaneously decided not to show the task bar at the bottom of the screen, and some menu bars have been messed up. How can I fix this?

My Firefox has spontaneously (apparently) decided not to show the task bar at the bottom of the screen (the margin is there, but it is blank), and some menu bars have been messed up. Perhaps the most annoying aspect of these changes is the fact that I have to use alt-tab to move from a Firefox session to another session.
I can find no way to fix these problems. Can you help? Am I going to have to uninstall and re-install Firefox in order to get back to the default settings? If so, is there any way to preserve my bookmarks?

Make sure that you do not run Firefox in full screen mode (press F11 or Fn + F11 to toggle; Mac: command+Shift+F).<br />
If you are in full screen mode then hover the mouse to the top to make the Navigation Toolbar and Tab bar appear.<br />
You can click the Maximize button at the top right to leave full screen mode or right click empty space on a toolbar and use "Exit Full Screen Mode" or press F11.

Voice mail worked at one time now it shows the message but no longer allows me to play it!?! How do I fix this?

Plz help w voicemail. Worked at onetime, now shows I have a message, but will not play. Says there is 0.0 recorded.

It is possible that your security software (firewall, anti-virus) blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

My MacBook won't go past the gray startup screen.

I shut down my MacBook pro during a software update because the update appeared to have frozen. When I tried to reboot my computer afterwards, it would go to the gray startup screen with the spinning gear and not progress any further. I have tried multiple times to restart it, each time getting the same result, I have also tried starting it up holding down shift, another time holding down control option p r, and also holding shift. Each time gave me the same result of freezing at the gray screen. Any idea on what I can do to resolve this problem?

Hi,
This article may help. What happened was a kernel panic. They can be caused by either hardware or software. Try the syeps outlined in the article and post back the results.

I have a PB G4 that won't start. It shows the gray apple screen, shows the blue screen, and then the screen goes black, and "sleep" light pulses.

I have a PB G4 that won't start. It shows the gray apple screen, shows the blue screen, and then goes black. The sleep light pulses. From there, I can't turn it off normally. I have tried restarting the PMU. And I have tried unplugging the ac adaptor and removing the battery. From there I have plugged only the ac adaptor in, and it will begin to start but do the same thing once it shows the blue screen.
I tried only using the battery (without plugging in the ac adaptor) and the same thing happens. I tried starting the computer while holding down CTRL, Option, P, and R, waiting to hear the start up chimes 3 times, and then holding Shift as it starts up. But I still get the black screen once I see the blue one, and the computer's sleep light pulses.
I need something very important from this computer. And was able to start it last night. I did not shut down the computer, and was going to take it to a friends to use his printer today. The computer was in sleep mode in the morning.
Thanks for any help!

What your describing could be a logic board or memory issue.
You did or did not hear 3 startup chimes? If you hear 3 chimes when you start it, that would indicate a memory problem. Try reseating the memory to see if that makes a difference. If you have 2 RAM cards, try one then the other in each slot. If you have 1 RAM card, move it to the other slot. Powerbooks can develop one bad slot.
You may need to pull the hard drive out of the Powerbook, put it into an external case, then read it from another mac.

My computer won't start up past the gray screen

My computer won't start up past the gray screen and then shows up with the forbidden sign where the apple logo should be. I have tried booting in safe mode and PRAM and neither works. Any suggestions on what I should do next? Or any idease of what might be wrong?

I had the same problem, I believe it is called a kernal panic. They had to replace my hard drive. I did have apple care or it would have cost $450. The guy at the genius bar did some tests to see if he could fix it, he couldn't, so I had to have the hard drive replaced.

I can't get the laptop to start. I get to the gray linen screen with a gray apple and stop. It will not ask for log in.

What do I do now?

Hold the shift key at boot time, then run through this list, did you install anything recently or perform a update of some third party software? Uninstall it.

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load 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.
Please take this step regardless of the results of Step 1.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is 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 log in 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 Steps 1 and 2.

I do hope you have recent backup, because it look like your hard disk is failing. You can start up in Recovery Mode, and run Disk Utility to see if the disk can be fixed: OS X: About OS X Recovery - Apple Support

It means, tentatively, that system files are missing or damaged and you will have to reinstall Snow Leopard. See the following:
Reinstall OS X without erasing the drive
Do the following:
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 the Combo Updater for the version you prefer from support.apple.com/downloads/.

When I sync my devices its starts to sync then it says "canceling sync" how do I fix this problem?, I am running iOS7 on my devices and the newest version of iTunes on my MacBook Pro with Mavericks.

The first thing that I always do when I have issues syncing is quit iTunes, restart my Mac and reboot my device.
Reboot your device by holding down on the sleep and power buttons at the same time for about 10 seconds until the Apple logo appears on the screen and then let go of the buttons.
