I tried to run the firmware update and then my mac stopped working.. How can I fix this?

We have two brand new mini macs at our office that we are tyring to install updates on. One worked no problem, and we attempted to do the same thing on the second and there are issues. After I attempted to update the firmware my mini mac appears to still be running, light is on and it sounds like it is running, but nothing is starting up. How can I fix this?
Thank-you,

Try (but I do not expect anything)
Press Option during startup
Start up in Startup Manager, where you can select an OS X volume or network volume to start from.
Next try:
Press Command-R during startup
Start from the OS X Recovery System1
and if successful use the Disk Utility to repair the boot disk

The iTune cannot detect my iPhone. I have already tried all methods suggested, including re-installling iTune, re-activating Apple Mobile Device, plugging in various USB ports, and etc. I use windows 7. How can I solve this?

The iTune cannot detect my iPhone 4S. I have already tried all methods suggested, including re-installling iTune, re-activating Apple Mobile Device, plugging in various USB ports, and etc. I use windows 7. How can I solve this?

The new cable is completely new, and my computer can detect the phone as a drive, and battery charging is ok. So I believe the USB cable works properly. It is so weird that just iTune itself cannot detect the phone, and it is of the most updated version. What else can I do? Thanks.

I have a Mac Pro with four hard drives. I currently have Lion installed on one hard drive. I want to have the option to boot from either Lion or Snow Leopard. How can I do this?

It's best to install Snow Leopard on one of the three remain drives without an Operating System.
You can then install the applications you need from the original media. Create a User Account using Setup Assistant.
Do you want to migrate User Accounts from the OSX LIon boot drive, or are you keeping the User Accounts separate?
Dual-booting just requires holding the option key during startup and selecting either Lion or Snow Leopard.

Try updating to iPhoto 9.4.1. If it's not appearing in your Software Update yet, try updating using a .dmg installer downloaded from the following page on the Apple website:
iPhoto 9.4.1
From the release notes for the new version:
What's New in Version 9.4.1
Improves the reliability of syncing to iOS devices via iTunes
Fixes an issue that could cause iPhoto to quit unexpectedly when using the Export command
Addresses an issue that could cause iPhoto to quit unexpectedly when upgrading multiple books, cards, and calendars

I'm installing windows 7 64-bit on my imac which I've done before but I get a message that the partition is GPT even after I format the bootcamp partition. I just upgraded my hard drive to a 3tb and I'm allocating 1tb for windows. How can I fix this?

No easy fix for a few reasons:
1) Bootcamp requires a hybrid MBR for the partition table. That is: both an MBR and a GPT partition table at the same time with the GPT one having all partitions and the MBR one having only the ones that are relevant, but at most 4 of them (including the protective partition and the Macintosh HD one). Which leads us to:
2) The MBR part of the hybrid partition table cannot work with 3TB hard drives. MBR is limited to 2TB.
I am working on a small EFI app that can boot Windows in EFI mode on a Mac and that would mean that you can go GPT only on your system. The progress of the app is slow due to the nature of EFI and for now requires that you do an unattended Windows install with slipstreamed graphics drivers, but we are adding VGA loading on top of EFI quite soon after the rest of the app stabilises. The status of the app is documented at:
Win7 x64 booting natively via EFI (no bios emulation)
Windows does actually successfully boot in EFI mode on most Macs (anything with a 64bit EFI should work), but does not have graphics support even if you load the driver due to the VGA pci registers not being set by the firmware. Furthermore, in Setup and Safe Mode, Windows uses VGA instead of GOP which is a failure by design since VGA is a BIOS standard and not really compatible without hacks with EFI. Other EFI implementations also add VGA compatibility at a high cost to the firmware complexity for the VGA cards available on the market that don't actually contain anything in their ROM except the VGA BIOS.
My recomendations:
1) Install on a second smaller hard-drive; or
2) Wait for the EFI app to come out officially and use that to boot Windows Vista SP1 x64 and Windows 7 x64 (RTM and SP1) in the native EFI mode.
3) Wait for Windows 8 which supports VGA-less booting acording to the AMD presentation at UEFI Plugfest.

I'm help a friend with a new 4S iPhone. He's converting from an old 3GS. We've gone throughout the activation, update to iOS 5.0.2 and restored. Now I'm surprised to find that the Facetime app is not on his new 4S iPhone. How do we fix this?

I would suggest you read the user guide. There IS no Facetime App for the iPhone.

I am getting error message that says "the iTunes store is currently unavailable......how do I fix this?

I keep getting iTunes store is currently unavailable when I try to view my purchased content on my apple tv 2. How can I fix this?

I just saw the date of the original post and so this doesn't help them...but anyone doing searches as I did for help...hopefully this will help you.
I posted this in another thread, but sounds like you have the same problem I have. I can watch youtube, and even trailers, but I cannot watch any of my purchased movies and I can't rent movies either. It originally started after my 5.1 update and sporadically I would get the error in loading content...now I get an iTunes connection error as well.
So, I finally decided to pay 20 bones for support to find out what is wrong. Apple support confirmed there is a "number of people" having this issue and he thought there would be an update soon since they have been working on the problem for a couple of weeks. And he told me they wouldn't charge me for the call.
A little frustrating.

Thanks Jeff, I was not aware that a template could be multi-page. (All the existing templates were 1 page)
But it worked, saving me some steps. When I was finished I renamed the document, and locked it.
Then tried to save it but could not because it was locked. I closed it, went to my Spread Sheet Folder ,
to find it, it was not there. The Finder could not find it either.
So I start over again.
I opened up Numbers and it showed my personal Numbers template folder, it contained both my new
original 4 page template and the vanished saved document!
I tried to delete the template containing these document data and could not - I had to go to the Library/Application Support/Numbers to physically remove it from this folder. Then I started over again. I Finally found out how to make it work: I can now "save as", and then lock, and it will go to place where I want it to be saved and locked.
The secret is: Click on the document title in the menu bar, and it opens up "Save as...", which works the same as in OS 10.4.11, and you can pick the place you want for saving. Once done that, you can then lock the document in the same pull down menu, and then close it.
I also found later that I can delete a template from its folder, by letting Numbers open the templates,
clicking on the one I want to remove, then go to the "Numbers Menu/File/Move to...", select "Desktop"
and from there the selected template can then be thrown into the Trash from there.
It appears now that the real fault of the Numbers software is that the "Save as" command is not available in the "Edit" or "File" pull-down menus, but hidden behind the title of the document.

The audio on my iPhone 4s cut out randomly; I have to unplug and replug headphones to get it back. How can I fix this?

For the last year I have been unable to use my iPhone speakers because of some bug. I can play music and audio through headphones, but that's it. And just today even the headphones became spotty. I'll play a song (through iTunes) for a while, then the audio will just cut out. I can get it back by unplugging and replugging the headphones (sometimes multiple times) but that fix doesn't last long; usually within a few minutes (if not much sooner) the music cuts out again.
I really don't want to buy a new one because this one otherwise works fine. How can I fix this?
