How can I deactivate a computer when i do not have it anymore?

Hi, I have used all of the 5 computers that I can authorize for my ipod and all of those computers have since died. Is there a way to deauthorize a computer without having the actual computer to do it from?
I do not want to delete all of them because my ipad is connected to my account (that is the only one that I still have), but I want to transfer all of the music from my ipod to my itunes account so I can put on my new iphone.
Thanks!

Authorization and Deauthorization
Macs: iTunes Store- About authorization and deauthorization.
Windows: How to Authorize or Deauthorize iTunes | PCWorld.
In iTunes you use the Authorize This Computer or De-authorize This Computer option under the Store menu in iTunes' menubar. For Windows use the ALT-S keys to access it. Or turn on Windows 7 and 8 iTunes menus: iTunes- Turning on iTunes menus in Windows 8 and 7.
More On De-authorizing Computers (contributed by user John Galt)
You can de-authorize individual computers, but only by using those computers. The only other option is to "de-authorize all" from your iTunes account.
1. Open iTunes on a computer
2. From the Store menu, select "View my Account..."
3. Sign in with your Apple ID and password.
4. Under "Computer Authorizations" select "De-authorize All".
5. Authorize each computer you still have, as you may require.
You may only do this once per year.
After you "de-authorize all" your authorized computers, re-authorize each one as required.
If you have de-authorized all computers and need to do it again, but your year has not elapsed, then contact: Apple - Support - iTunes - Contact Us.

What can i do my computer freezes when i use safari and word document?

My computer freezes when I am using Safari and word document. Can some help me??

The same thing just happened to my new ipod today while i was trying to use an app. A lot of people say that it is caused by an ios update, but I let the battery on my ipod drain until it turned off. Once i charged it, it turned on and is working normally again

How can I make my computer faster like it used to be?

My computer is slow to load everything and slow to switch between programs.

First, back up all data immediately, as your boot drive might be failing.
There are a few other possible causes of generalized slow performance that you can rule out easily.
Reset the System Management Controller.
If you have many image or video files on the Desktop with preview icons, move them to another folder.
If applicable, uncheck all boxes in the iCloud preference pane.
Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
Check your keychains in Keychain Access for excessively duplicated items.
Boot into Recovery mode, launch Disk Utility, and run Repair Disk.
Otherwise, take the steps below when you notice the problem.
Step 1
Launch the Activity Monitor application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Activity Monitor in the icon grid.
Select the CPU tab of the Activity Monitor window.
Select All Processes from the menu in the toolbar, if not already selected.
Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.
Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
Next, select the Disk Activity tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in and Writes out.)
Step 2
If you have more than one user account, you must be logged in as an administrator to carry out this step.
Launch the Console application in the same way you launched Activity Monitor. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Select the 50 or so most recent entries in the log. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.
When posting a log extract, be selective. Don't post more than is requested.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some personal information, such as your name, may appear in the log. Anonymize before posting. That should be easy to do if your extract is not too long.

Can i hook up a macbook pro to 2 HDMI monitors in the following way?

Macbook pro 13 2011 thunderbolt
okay so can i use:
Mini Displayport HDMI +
HDMI to Dual DVI
To
2 DVI monitors
will this allow me to use them as one extended desktop? or will it mirror those two monitors together?
id like to be able to use my macbook pro in close lid mode with a dual monitor set up

For your MBP you will need an adapter such as the following and an HDMI cable for video:
For audio, you will have to tap the audio output port and connect to the TV RCA audio input connections. This will give you an idea of what will be required:
Ciao.

Can I hook up my Dell Latitude for using iMac as display?

the Dell has VGA & HDMI so I wonder if it will work using a Moshi Mini DisplayPort to HDMI-adapter or similar?

If I understood you, you want to use your iMac as a display for the Dell Latitude.
See > http://support.apple.com/kb/PH11302 27-inch iMacs and iMacs with Thunderbolt ports can be used as a display, and Apple says that this feature works only for other Macs.
That's not exact and that's not the truth because an iMac can be used as a display for PCs, but the PC must have a DisplayPort or a Thunderbolt port. If your PC hasn't got DisplayPort, you can't use the iMac as a display

Sound from computer nolonger goes out through HDMI cord. Picture does. How can I fix this?

I have a HP Pavilion dm4 entertainment laptop with Intel core i5 m430 2.27GHz. Just recently - when I plug in an HDMI cable connected to the TV - the sound does not go to the TV. Previously it did. How can I determine what has changed to prevent this from happening?

Sorry - I meant dm4. Thank you for responding so promptly. Since I originally submitted I found the solution. I couldn't get it to change from the default laptop speakers in the sound mixer in the taskbar but when I went to the sound settings in the control panel with the hdmi plugged in and made the samsung TV the default speaker it went to the TV. I thought I had tried this before but in any case this time it worked. Again - I thank you for responding so quickly. Next time I may really need the aswer quickly.

How can I make my computer notify me when the power cord unplugs?

My power cord for my PowerBook G4 tends to unplug without my noticing. Is there a program I can download or can I write an script so that it makes a sound when the power cord unplugs?

That is the way Mac OS X 10.8 (aka Mountain Lion) works by default. Are you actually running that system? (See About This Mac in the Apple menu.) If so, make sure the check box in the shut down alert is checked:

Why can't I delete music from my iphone using itunes match anymore?

I thought for sure I used to be able to swipe to delete albums or tracks on my iphone - on my iphone 5 I can no longer do this. I found that if I turn itunes match off, I can delete. But turning itunes match on and off a lot is really a huge issue. It seems every time I do this the iphone loses track of some of the music.
Why why why can't these problems be fixed?!

Awful, awful awful.
Apple ... what were you thinking, and why did you mess up your product so badly?
Why are you screwing over those who are the most devoted, who paid for an extra?
Really. Could this be more frustrating:
You download a great new album!
You want to listen to it on your iPhone!
Oh wait, your iPhone is full. Over capacity. AND YOU SPEND AN HOUR TRYING TO FIGURE OUT HOW TO GET SONGS OFF YOUR IPHONE, reading every forum and every trick to somehow make the product work the way it should. Trying to clear some space for that great new album you just got!
But it still doesn't.
... frustrated, you end up deleting the whole library. Because there seems to be no other way to clear space.
And re-download.
But "use cellular data" is back on, so it downloads when you're out.
And your phone bill is now $300 because you live in Canada and the data caps are so low.
Great. Now I paid over $350 to get my music I already own onto the phone.
At this point, the old USB seems like a better option. Or even the firewire 400. Longing for the days of my 10 gig iPod with a FireWire cable.
Thanks. So much for "positive user experience".
Easy to buy music, hard to get it on to your device. But as long as I've already given you my money, who cares right?!

Need to no if a tv can be hooked up by hdmi from a beat all in 1 computer

HP Beats Special Edition 23-n010 All-in-One Desktop PC
trying to hook my flat screen tv through the hdmi cable from the computer to the tv using the tv as a second monitor. games like x-box and ps3 hook into the monitor and work fine. Its going out that don't want to work.. is it possable or not?? i know about the botton that changes in to out and out to in.. hooked up hdmi cord to computer and to tv. its not recnising the tv at all. i use a lap top with same hdmi cable and it hooks up fine, so cable is good. any help would be good. IS this possable or do i need to get a converter from USB to hdmi in orter to do this . i thought it was able to broadcast to the tv with hdmi or is this a out port only on this comoputer

Hi,
The HDMI port at the back is HDMI In port:
Figure 6: Back I/O ports
1 - DC power input
2 - DC power indicator
3 - Ethernet port
4 - USB 3.0 ports
5 - HDMI In port
that means it's ok to use xbox or PS3 but you can't use it for TV. If you wish to connect to a TV, you need an external USB video card or adapter.
Regards.
BH

I need to update to the latest version of Snow Leapord-currently running v10.6. Because of where we live the slow download speed for such a large file has kept me from downloading the update. What can I do short of hooking up computer elsewhere?

Do you ever visit a friend or realtive with a Mac who has faster internet? Maybe the local library has Macs on a fast line. If so, get a USB thumb drive and put this link on it from your computer:
http://support.apple.com/kb/DL1399
Then put this link on the drive:
http://support.apple.com/kb/DL1429
When you are at some place that has a Mac with a decent download speed. insert the thumb drive in that Mac and click on the first link ("DL1399") and direct the download to your thumb drive. Now do the same this with the second link.
The installer files will now be on the thumb drive and, when you get home, drag them from the thumb drive to your desktop. Install the Combo update first.

We bought a used Ipod Touch from a private party. We can download music when it's hooked up to the computer but can't download any games or songs by using the wifi. How can we change the password so we can do this?

You should restore the the iPod to totally erase the iPod and add your own media to the iPod.
Connect the iPod to your computer and restore to factory settings/new iPod via iTunes.

Can you hook up to ethernet

Can you hook up ethernet to express; have access to multiple computers, pick the one you want, drill down to that itunes library and play the associated songs and playlists? Also, is there a way to play internet radio; lastly can you control this via an iphone? if so how? is there an app that can allow users to access thier windows computer and see thier itunes library?

Yes it sounds correct. They can be Windows computers, they just have to be running fairly recent versions of iTunes and they all have to be on the same network. Wired or wireless makes no difference.
If you have an Express it can also join your network wirelessly or via Ethernet. They can be configured to connect to your network either way.
With the iPhone's Remote app you simply click the gear icon and click "add an iTunes library". You go to that computer and type in the code to authorize it. Sharing has to be enabled in iTunes Preferences also. Home Sharing uses your Apple ID so the other computers all have to use the same one.
Also, if you are using Windows you will almost certainly have to configure its firewall or anti-virus software. Such things are designed to hinder all sorts of communication and they're all different so you may be on your own trying to figure that out.
Apple has lots of instructions regarding Home Sharing, if you're not getting anywhere start with this:

How can i hook my old ipod to my new lap top without loosing my music

how can I hook up my iPod touch to my new laptop without loosing my music files

Syncing to a new iTunes library or computer will erase your iPod. Only if you back up your device manually before syncing, you can restore your device from that backup again. A manual backup does not include the sync process.
Do this:
Disable autosync in iTunes, connect your iPod to your new computer and right click on it in the device list and choose backup. iTunes will backup your ipod without syncing.
Transfer your purchases the same way, choosing "transfer purchases" this time.
When you connect your iPod for the first time, all media content will be erased. But you can restore your settings and app data from your manual backup afterwards.
Don't forget to set up at least one contact and event on your new computer to be able to merge calendars and contacts when you sync the device for the first time.
Music is one way only, from the computer to your device, unless you bought the songs in itunes and transferred your purchases.
There is 3rd party software out there, but not supported by Apple, see this thread:http://discussions.apple.com/thread.jspa?threadID=2013615&tstart=0

How many AppleTVs can connect to one computer?

I have a client that would like to set up a large number of 2nd Generation AppleTVs to be synced to one Mac's iTunes and iPhoto libraries.
What's the maximum number of ATVs that can connect to one computer? My client would like to connect 13, but is there a maximum number?

Bear in mind that unlike AppleTV1 you cannot AFAIK specify different photo content to different AppleTVs - you'd therefore need to get the 13 'different' slideshows on each maybe using events, then manually choose the differing slideshow to run if doing all of this remotely.
If someone could walk around and just hook a laptop up to each AppleTv to transfer photos over ethernet you'd have more flexibility, but this would be a chore if AppleTV lost photos for any reason.
I don't use photos much with ATV2 and am unsure if they survive a reboot or power outage in memory. Also unsure if there's a limit to the number of photos that can be transferred.
