How can i get fallout 2 to work

How can I get Fallout 2 to work on my mac book pro. I just got my computer and the graphics are all messed up. I tryed installing it on a friends computer and it worked. He has a mac book pro that is only about 8 months old. Why wont it work on mine?

Ask your fellow MBP owners -
MacBook Pro
http://www.apple.com/support/macbookpro
I hope none of you are getting it off torrents, always trouble in that dept.
Maybe it needs a patch for yours and ATI 6xxxx mobility.
It helps to know the specs, and model number (17"? etc)
http://support.apple.com/specs/#macbookpro
Graphics and video support
AMD Radeon HD 6490M graphics processor with 256MB of GDDR5 memory on 2.0GHz configuration; or AMD Radeon HD 6750M graphics processor with 1GB of GDDR5 memory on 2.2GHz configuration
Intel HD Graphics 3000 with 384MB of DDR3 SDRAM shared with main memory5
Automatic graphics switching
Dual display and video mirroring: Simultaneously supports full native resolution on the built-in display and up to 2560 by 1600 pixels on an external display, both at millions of colors
so it could be getting messed up with using the Intel graphics - for all I don't know - or you have 6490M with just 256MB

I have an iphone4 and my husband merge his numbers with mine and i think it was deleted can you tell me how can he get his number back on his phone

Do you possibly mean the contacts have been merged?
If so, where are each of you syncing contacts? A supported application on the computer? iCloud or another cloud service? An Exchange server?
WIthout details, it's difficult to offer specific resolutions.

Will not work. To my knowledge, dual converting like that isn't supported. The Mac must detect the connected video output device and that sort of info cannot be done across an analog component uni-directional connection.

Can you start Firefox in [[Safe mode]] ?
You can also do a clean reinstall and download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
You can initially skip the step to create a new profile, that may not necessary for this issue.

I recently transferred my ipnone service from at&t to another carrier the phone worked fine until i tried to up it with itunes i now have a frozen itunes logo and a plug on the screens my phone is a iphone 3g how can i get my phone to work again?

my ipone 3g is frozen with aitunes logo and plug after i tried to update it from apple. the phone worked fine even thou i changed carriers from at&t to Simple celleur. How can i get my phone to work?

As AT&T has not officially unlocked your phone it must have been hacked to use another carrier. So when you updated it has relocked itself to AT&T. There is no official unlock so this will happen anytime you update.

You did install the latest iTunes (10.5) right? If the problem was that iTunes does not see the iPod try:
iPhone, iPad, or iPod touch: Device not recognized in iTunes for Windows
or

Hardware missing -AGP Graphics card. How can I get my FCE 4 working on the new computer? Cheers

Hi I have just upgraded my computer to Mac OSX 10.6.7 now I cant open my FCE 4. Message reads, Hardware missing -AGP Graphics card. How can I get my FCE 4 working on the new computer? Cheers

Thanks, just so I know we are talking about the same items please let me know - When you say "run Prokit" do you mean downloaded? Which I did. I dont have Prokit 4.0.1 if you are referring to that, do I need this first? Please explain what application name I am looking for if other than Prokit which is sitting in my "download folder" do I need to manually put it into the apps folder? Sorry if the questions are layman but this area is not a very strong point for me. Thanks for your help so far.

How can I get my speaker to work again?

How can I get my speaker to work again? I've tried turning my phone off and on, hard reset, removing SIM, cleaning out dust, using the hair dryer, network reset, cleaning headphone port, made sure the phone was not on vibrate,and made sure "Change with buttons" was on. There was no liquid/moisture damage. I was watching a video on youtube and all of a sudden my speaker went out. If I tap on the speaker it goes in and out but does not stay on/loud.

Do you get sound in any apps e.g. in Music and Videos but not notifications or sound in other apps ? If you do get sound in Music and Videos then have you got notifications muted ? Only notifications (including games) get muted, so the Music and Videos apps, and headphones, still get sound.
Depending on what you've got Settings > General > Use Side Switch To set to (mute or rotation lock), then you can mute notifications by the switch on the right hand side of the iPad above the volume switch, or via the taskbar : double-click the home button; slide from the left; and it's the icon far left; press home again to exit the taskbar. The function that isn't on the side switch is set via the taskbar instead : http://support.apple.com/kb/HT4085
If you don't get sound in any apps then have you could try a soft-reset to see if you get sound after the iPad has restarted : press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.

How can I get my ipod to work with itunes?

When I connect my ipod classic into my new computer it seems that itunes does not recognize it. How can I get my ipod to work with itunes? I'm afraid to disconnect my ipod because the display is saying Do Not Disconnect.

1. Update iTunes to the latest version. Plug in your iPod. If iTunes still can't recognize it, then in iTunes in the top left corner click help> run diagnostics. On the box that comes up, check the last two things. Click next and it should identify your iPod.
2. Click on your windows start menu. Type in "services". Click on it and when it pops up, on the bottom of it click on "standard". Now Scroll down to find "Apple Mobile Device" Right click it when you see it and click on "Start". When it has started, close iTunes and replug in your iPod and it should show up.
3. Check the USB cable
4 Verify that Apple Mobile Device Support is installed
5. Restart the Apple Mobile Device Service and verify that the Apple Mobile Device USB Driver is installed.
6. If you just want to add some photos, songs and movies from computer to your devices, you can use an iTunes alternative to do the job
7. Check for third-party software conflicts.

I do backup with iCloud. I can't wait until the new iMac is available so that I can once again have my files in more than 1 location without needing to rely solely on the cloud.
I also rely on iTunes and my MacBook and Time Machine as well as backing up to iCloud. I know many users know have gone totally PC free, but I chose to use iCloud merely as my third backup.
I assume that the restore would result in my ability to open Pages and Numbers and fix the problem with deleting apps, but this would also mean that if my Numbers documents still exist solely within the app and are just not on iCloud for some reason that they would be gone forever. Is that right?
In a word, yes. In a little more detail.... When you restore from an iCloud backup, you must erase the device and start all over again. There is no other way to access the backup in iCloud without erasing the device. Consequently, you are starting all over again. Therefore, it would also be my assumption that Pages and Numbers will work again and that the deleting apps issues would be fixed as well.
If the documents are not in the backup, and you do not have a backup elsewhere, the documents could be gone forever.
