Hi Kappy Thanks for your answer. I did a reboot on my Macbook as suggested and this operation is going on non stop for 14 hours and on the screen always appears the same message that you can see in the picture in attachment. Any ideas?

My MacBook Pro won't restart after updating iTunes, and so the update doesn't work. I have just purchased an iPad mini and can't sync it - can anyone help?

Press and hold power button for up to 30 seconds. Remove battery and reinsert then repeat.

I am having problems shutting down my MacBook Pro. I go to the apple and click shutdown or restart, it appears the shutdown process starts, the screen goes blue and the little circle keeps going round and round, but nothing happens even after 30 minutes.

Make sure you quit all your applications before shutting down.
And try resetting the SMC.

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.

I just installed OS X Yosemite on my MacBook. I now cannot get the computer to start up. If I hold down the power button to try and power it back up, it will not start. Any ideas on how to fix this?

Reinstalling OS X Without Erasing the 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.
Reinstalling OS X Without Erasing the Drive
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility and press the Continue button. After Disk Utility loads select the Macintosh HD entry from the the left side list. Click on the First Aid tab, then click on the Repair Disk button. If Disk Utility 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 Disk Utility and return to the main menu.
Reinstall OS X: Select Reinstall OS X and click on the Continue button.
Download and install the OS X Yosemite 10.10.3 Combo Update.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
Alternatively, see:
Reinstall OS X Without Erasing the Drive
Choose the version you have installed now:
OS X Yosemite- Reinstall OS X
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

Hey High Socks,
Thanks for the question. If I understand correctly, iTunes isn't working when you try to launch it. I would recommend that you read this article, it may be able to help you isolate or resolve the issue.

There was add one and i lost it after the update and i don't remember it's name

there was add one and i lost it after the update and i don't remember it's name
it was add-on to show me the source of any click able content
like pics on twitter or Facebook
also the videos on youtube
and it showed a little icons with small pic shape on it with different colors
and also sometimes with a small lock shape on it
now i need to know what this add -on name or how to get it back

Add-ons are not auto-deleted as far as I know...
It's possible that the extension or userscript simply doesn't work correctly in Firefox 22 due to a change in Firefox. If you look at the add-on pages, often the reviews will mention whether the add-on is broken in a new release.

My MacBook Pro has slowed to a crawl. It started when I was printing off the Internet. Now I get the spinning circle in just about every move. Any help?

I had this problem as well but found the soultion on another post from turingtest2 - it worked for me:
Go to Control Panel > Add or Remove Programs (Win XP) or Programs and Features (Later)
Remove all of these items in the following order:
iTunes
Apple Software Update
Apple Mobile Device Support
Bonjour
Apple Application Support
Reboot, download iTunes, then reinstall, either using an account with administrative rights, or by right-clicking the downloaded installer and selectingRun as Administrator.

I suspect you have a 2G iPod. Those can only go to iOS 4.2.1.
Identifying iPod models
iPod touch (3rd generation)
iPod touch (3rd generation) features a 3.5-inch (diagonal) widescreen multi-touch display and 32 GB or 64 GB flash drive. You can browse the web with Safari and watch YouTube videos with Wi-Fi. You can also search, preview, and buy songs from the iTunes Wi-Fi Music Store on iPod touch.
The iPod touch (3rd generation) can be distinguished from iPod touch (2nd generation) by looking at the back of the device. In the text below the engraving, look for the model number. iPod touch (2nd generation) is model A1288, and iPod touch (3rd generation) is model A1318.
You also said: "It also will not let me download any music onto it." What happens when you try to sync music to the iPod?

I'm having problems upgrading from 10.6.8 to Yosemite. My computer locks up after the download and installation process. Does anyone know how I can overcome this problem?

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.

I cannot eject a CD from my MacBook Pro. I tried restarting the computer and holding down the mouse and restarting it to no avail. On Finder, nothing is showing up on the CD Drive. Any ideas on how I can eject it?
