Why do I sometimes suddenly lose Bluetooth from my Imac? I use it for my wireless mouse and keyboard. I then can't find it in system preferences but have to shutdown my Mac and hope it comes back

This is an infuriating problem and wondered if it happens to other people too and if I am doing the right thing by turning the Mac off then on again.

TS1814 I had to restore my Ipod Touch and now I can't connect to anything on it. When it asks for my Apple ID it comes up with an error message and says that it can't connect to the server. I have checked my WiFi connection and its connected.

Just downloaded Mountain Lion and want to remove natural scrolling; I went to system preferences, but I don't have a mouse. How can I get that to open to change the scrolling?

I need to apply for a job but I'm told I need to enable cookies and java script, how do I do that? I can't find it in system preferences

I just updated to the new operating system which i'm starting to think was a bad idea, because it reset all my settings and I don't know how to fix them.

so when I go to safari>preferences>security>uncheck box labled enable java script links on webpages don't work and pictures and links son't want to appear on websites. this made it so webpages don't want to work past loading the content in text format. I have to check enable java script to go the webpages to work right so images and links work again but when I try to apply for this job the error message pops up saying I need to enable cookies and java script.
SO I GUESS MY QUESTION IS IF JAVA SCRIPT IS ALREADY ENABLED HOW TO I ENABLE COOKIES?

Have used Firefox for over a year with no issues now can't access certain games......all else works, and the games can be accessed using Chrome and IE have run malware and still nothing

So I have used Mozilla for a long time with no problems. All of a sudden I cannot access certain games on facebook. All else works. First uninstalled and reinstalled. Then ran malware program. Still nothing and the games work off IE and Google Chrome. I really like Firefox and would like to be able to go back to it

I see many charges from AppleITUNES on my credit card for items I thought were free. How can I find out what each one is for?

I see many charges on my credit card for Apple ITunes that I thought were free. How can I find out what they are for specifically?

You can also call your credit card company to mail you an itemized list of what you purchased from iTunes Store plus get the information over the phone as well.

Two issues: screen flickering on long shots in HD and why does Apple TV2 suddenly loses content from my iTunes library at random times

Hi.
I'm genearlly happy with the idea of my Apple TV 2, but I've got two problems with it that keep popping up and I have no idea how to fix them:
1- Watching HD video causes the image to flicker on long shots. My TV is a 40" Sharp Aquos from 2010. SD content seems fine. Tried several HDMI cables and no dice.
2- At random times, the Apple TV 2 will lose all the information from my itunes libraries. It'll still connect but give me the message "There are no items" or something similar. My current workaround is to disconnect from home sharing, then reconnect and enter my username and password with the Apple remote (remote app on iPhone no longer works at this stage) which is a pain, because my PW is complicated.
Any solutions?
Thanks!

Welcome to the Apple Community.
1- Watching HD video causes the image to flicker on long shots. My TV is a 40" Sharp Aquos from 2010. SD content seems fine. Tried several HDMI cables and no dice.
There may be a couple of reasons for this. It may simply be poor encoding. Alternatively stuttering can become quite noticeable on panned shots when the the framerate of the video does not match the TV output frequency.
2- At random times, the Apple TV 2 will lose all the information from my itunes libraries. It'll still connect but give me the message "There are no items" or something similar. My current workaround is to disconnect from home sharing, then reconnect and enter my username and password with the Apple remote (remote app on iPhone no longer works at this stage) which is a pain, because my PW is complicated.
Intermittent problems are often a result of interference. Interference can be caused by other networks in the neighbourhood or from household electrical items.
You can download and install iStumbler to help you see which channels are used by neighbouring networks so that you can avoid them, but iStumbler will not see household items.
Refer to your router manual for instructions on changing your wifi channel.

My windows 8 pc can not find my printer plugged into my airport extreme. My mac and desktop computer running win 7 can. Help.

i can print from my win 7 and macbook air. however when running bonjour printer wizard on win 8 laptop, my printer does not show up on the list.

Thanks. It turns out that since I had received this printer as a cast-off from the office, it was still config'd with the old IP info. Once I set it for remote configuration (enabling something called "BOOTP" in the TCP/IP config sub-menu), I printed off the status page to find that all the addresses (IP, subnet, gateway) were "unspecified" with 0.0.0.0 values. But when I went back into the printer config menu, disabled BOOTP, and looked at the IP address, I saw that the printer had rec'd a new IP address (10.0.1.5) from the AEBS, I presume (I confess that I am by no means an experienced networker). I reprinted the status page to confirm the 10.0.1.5 IP, then I used that IP to install the printer on the PC via the method you suggested and everything works fine, thanks! One concern for future use, though. Is it possible that if the printer, AEBS, or PC are powered off and restarted, that the IP address of the printer will be changed by the AEBS and I will be unable to print to it? Since IP assignment by the AEBS is dynamic (right?), will this affect future printing? Something to do with DHCP renewal?

Why my iphone cant hear voice call from an android phone using viber apps?

Why my iphone4 cannot hear voice calls from an android phone using viber free call apps?

I second the question posed by Rysz....if you have ANYTHING set up at all (a mail account, etc) it will communicate with it's server..whether polling for new mail, syncing notes, etc.
Also, the 4S is designed to be PC Free, so check your General settings tab to make sure it's not checking for Software Updates. Also, are you backing up to iCloud? This will automatically do things in the background. Check the iCloud settings page.
And to ensure no apps are running, double click your home button. When the screen raises up it will show icons of any running apps. Hold your finger on one of them, and they will start to dance with X's on the corners. Tapping the X's closes the app. Close them all, then hold your home button and power button at the same time. Slide to power off, leave it off for a minute, then power back on. This will ensure no apps are running in the background.

Photos on iPad and iPhone that i can't find on iPhoto...

Photos on iPad and iPhone that i can't find on iPhoto...

i have imported everything... photos have been deleted on iphoto but still show up on ipad and iphone... even after being synchronised.

I just purchased a new airport extreme 802.11ac I set it up and runs fine when i put my mac to sleep i come back and it can not find my airport i have to restart

I PURCHASED THE NEW AIRPORT EXTREME 802.11AC I SET IT UP AFTER I PUT MY MAC TO SLEEP I COME BACK AND IT SAYS CAN NOT FIND AIRPORT EXTREME I HAVE TO RESTART AND IT FINDS IT.

Try the following, in order, until (hopefully) resolved:
1a. Delete Preferred Network(s)
System Preferences > Network > Wi-Fi > Advanced > Wi-Fi tab
Under "Preferred Networks," delete the network(s) you regularly use from the list.
1b. Delete AirPort Keychain Entries
Launch the "Keychain Access" application located in Applications/Utilties.
In the windows on the left side: Select login for Keychains and "All Items" for Category.
Click on the "Kind" filter at the top, and look for any "AirPort network password" entries...and delete them.
1c. Add Preferred Network(s)
System Preferences > Network > Wi-Fi > Advanced > Wi-Fi tab
Add the preferred network(s) using the "+" button.
Restart or log out then back in.
2. Move System Configuration Files
(Note: You will have to reestablish your network connections settings.)
Go to /Library/Preferences
Move the SystemConfiguration folder to the desktop.
Restart your Mac. (Note: OS X will rebuild the files that are now sitting on your desktop. If this doesn't resolve the issue, you can move the folder back to it's original location.)

Why would my iphone suddenly lose charge rapidly (6-7%/hr) with no use

Why would my iphone suddenly lose charge rapidly (6-7%/hr) with no use?

I had the same problem with my iPhone 5 AFTER I had upgraded to IOS.
Did a good deal of searching on this site and others and found that the main advice being given was to turn off all apps that are running in the background (From the home screen double press the home button and a visual list of all apps running in the background will appear. To turn them off simply swipe your finger upwards on each).
Found that this definitely solved my problem and now make sure I do this every time I use the phone.
Hope this helps

HT5622 My husband and I both have iPhones. We are currently using the same Apple ID. I have my own ID but when I send him a text message it comes back to me or goes to my computer. How do we separate the 2 ID's so we can send messages?

You need to reconfigure your phone for use with your Apple ID. I suggest you restore yours as new then reconfigure it with your information and Apple ID. Be sure to disable Find My Phone, if it's enabled, before proceeding.

I have just bought a mac and also have windows installed but how do i change from windows into mac?

I have just bought a mac and need to know how to change from using windows into Mac. When the mac starts up windows come up but i want to use Mac?

To set the default boot volume use the Startup Manager system preferences once you are booted back into the OSX. Then you would only need the option key at boot time to boot into the "other" OS.

I have forgotten my password for iPod Touch 4G and it is now disabled. I tried connecting to iTunes but i haven't synced before and i need to enter the password before i can back it up so i can restore it. I don't want to lose pictures so please help!

Disabled
Place the iOS device in Recovery Mode and then connect to your computer and restore via iTunes. The iPod will be erased. That is how it works
iOS: Forgot passcode or device disabled
If recovery mode does not work try DFU mode.
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
For how to restore:
iTunes: Restoring iOS software
To restore from backup see:
iOS: Back up and restore your iOS device with iCloud or iTunes
If you restore from iCloud backup the apps will be automatically downloaded. If you restore from iTunes backup the apps and music have to be in the iTunes library since synced media like apps and music are not included in the backup of the iOS device that iTunes makes.
You can redownload most iTunes purchases by:
Downloading past purchases from the App Store, iBookstore, and iTunes Store
If problem what happens or does not happen and when in the instructions? When you successfully get the iPod in recovery mode and connect to computer iTunes should say it found an iPod in recovery mode.
