Go to http://appleid.apple.com.
To clarify, the mere act of changing the Apple ID on the device will not remove any content. But you cannot update the apps or re-sync them if they get deleted without the old Apple ID. It may be best to download them again with the new ID.

Can anything be done to change the white on grey color scheme in Bookmarks?

I just upgraded my Mac Book Pro to OS X Version 10.9.1. I was horrified when I got a look at what Apple has done to Safari! I have macular degeneration - which means that my eyesight is slowly fading away. Bookmarks was especially difficult because all of the bookmrks are shown with a white on grey color scheme. And when the "new" Apple color schemes are not white on grey - they are grey on white. I simply can NOT see anything which is white on grey. OR white on ANY light color. In order to be able to see anything, I need to have contrast. For example, as I type on this page, the scroll bar is grey on white. It has become almost impossible for me to find the scroll bar on most pages. Previously, my scroll bars where usually bright blue. I can see bright blue on white - but NOT grey on white. I can read white letters on BRIGHT or DARK Blue -but NOT light blue.
Apple has made SO many strides in makes computers accessable to those of us who have no other choice except to deal with disabilities! Can ANYTHING be done to change the white on grey color scheme which Apple has adopted throughout its system?
Now, in order to use my Bookmarks, I have to go to my Edit Bookmarks page. Even that solutation is not all that helplful, because the lettering on the Edit Bookmarks page is so small.
Also - I discovered that the "new" Mail pages had the same problem. For the most part, the "innovations" in mail make all of the pages too busy for me to be able to sort my mail or keep track of it in any way. I had to choose to return to the "classic" mail option to be able to get a reasonable facsimile of being able to handle my E mail accounts!
And, of course, once again, the scroll bar on my mail accounts is also grey on white - so it takes a lot of searching for me to just find the scroll bar when I need to scroll down in an E mail!
ALSO - I was equally horrified when I discovered that the Upgrade to Version 10.9.1 made it impossible for me to visit some of my favorite music pages - most of which use MIDI files! I can no longer hear any of my favorite MIDI music pages! I TUNES, of course, is in love with people like Lady Gaga - the type of performers - and performances - which have no relevance to older Americans.
I do volunteer work at a local Assisted Living facility and one of the greatest advances we have been able to make with Alzheimers patients is the way in which Senior Citizens respond to music from their time period. Unfortunately, most of the music which senior citizens prefer to listen to is music which has been preserved in MIDI pages. A few weeks before I "upgraded" my Mac Book Pro - I could take my computer over to the local Assisted Living Facility and play music from Hymn Time's Cyberhymnal or the Angelwinks tunes - but I can NO longer do that with the current Apple "upgrade" in version 10.9.1 - because the music from those MIDI pages can no longer be heard by anyone! The page comes up and you can see the writing - but no one can hear any of the music. We understand that a group in Switzerland has been working on an APP for I Phones which DOES make MIDI files accessable - so surely it should be possible to provide a way for Version 10.9.1 users to listen to MIDI files, such as those provided by Hymn Time's Cyber Hymnal or by Angelwinks!
You will notice that I changed the font for this to Arial Black - primarily because I could NOT see what I was writing when I first began - because, once again, the color scheme was grey on white.

Adobe Bridge has been deleted and needs to be re-installed. How can this be done without reinstallin

Adobe Bridge has been deleted and needs to be re-installed. How can this be done without reinstalling the entire CS5

Hi RDMDanielM,
Welcome to the Community!
We cannot install Adobe Bridge as a Standalone product, you can just reinstall Photoshop and Bridge will be reinstalled with it. Go ahead and start uninstalling CS5 suite but choose Photoshop from the list and the same will be applicable while Installation.

That version cannot be upgraded further if it's a 2G model. The 3G model can be upgraded to iOS 5.x.x. You can't have a 2G model because the maximum iOS version is 4.2.1.

Can I update imovie without changing my projects in imovie that haven't been published?

Jimmyalford,
I am having the same exact problem that you describe. Can't figure it out. I've got a really high speed signal, too. No luck.
GeeD, I do not have macKeeper installed. And I am running iMovie 10.0.2.
I hope someone can shed some light on this.
Thanks all....

I assume you have the S/Ns. The download is at http://helpx.adobe.com/acrobat/kb/acrobat-downloads.html. Be sure to backup the download to CD or backup HD for future use.

How can I use QuickTime SDK to get Compress format of Video stream?

I can get uncompress video stream like this:
QDerr = NewGWorldFromPtr( &m_hGWorld, k32BGRAPixelFormat, &rcMac,
NULL, NULL, 0, (char*)m_pVideoBuffer,
m_sAVFileInfo.sResInfo.ulWidth*4);
then the m_pVideoBuffer is uncompress video stream. How can I use QuickTime SDK to get Compress format of Video stream? I could change "k32BGRAPixelFormat" to other format,use other API or something?
Could someone have the method? Best Wishes!

Firefox, I would make sure you update your Desktop to Firefox 14.0.1, as the version you are running is quite old and out of date.
Then, do you have your Sync Recovery key, username and password? If you do, you can re-add Firefox Sync to your computer.

I currently have wireless, but i am looking into this to maybe have faster wireless. if this is hooked up, will the existing wireless/ethernet to pcs still function without changing them to use the airport express?

I want my wife to be able to see my calendars on my IPad /I phone on her mac and for her to add to it . She can then see my work movements and also add in any important events from home life. Can it be done without sync of email and contacts?

I would like my wife to see my calendar on her mac from my iPad so she knows my work movements and can add in any important events I need to be aware of at home. Can I do this without upsetting her mac/iPhone arrangement and without sync of contacts and email?

I'm not sure how iCloud will handle this, but I believe it will allow something along these lines - cloud syncing of the calendar between two. For now, you could just move your calendars to Google calendar and sync it to your iPad - then - you can subscribe to each other's calendars, give priviliges to add events to them, etc.

Can't open any version of iTunes or use quicktime

yesterday i downloaded and installed iTunes 7 (before i knew that there was problems with it). when i opened it massive chunks of my library were missing so i decided to revert back to an earlier version of itunes. removed iTunes 7 and installed iTunes 6.0.5 (think that's the correct number) but it wouldn't open. it comes up with a message saying that iTunes had encountered an unexpected error and needs to close. i've tried uninstalling and reinstalling different versions of iTunes and rolling back to various system restore points on my computer but i constantly get the same message. I can't use quicktime either - it just comes up with the same message.
HELP!!!

I can't use quicktime either - it just comes up
with the same message.
just doublechecking your precise error message. is it
an "itunes has encountered a problem" message? or is
it something a bit different? if it's different, what
is the precise text? (include error message numbers
if you're getting any.)
i don't know if this will mean anything to you...
Faulting application pictureviewer.exe, version 7.1.3.100, faulting module unknown, version 0.0.0.0, fault address 0x63656666.
for some reason the error message i was getting on screen when i tried to open QT isn't coming up now but QT isn't opening either. i got that text from going to control panel>admin tools>event viewer. the text i was getting previously when i tried to open QT was "quicktime has encountered an unexpected error and needs to close" (or something v similar).

Can't get iPhone 5 recording to work using Quicktime on Yosemite

QuickTime on Yosemite now has this nifty feature where you can record your iPhone, provided you connect it using a lightning cable. Now I've done all that, but when I open QuickTime and select my iPhone from the dropdown menu next to the record button on QuickTime, it stutters and fails to pull my iPhone's image to my mac. If I press record anyways, it crashes.
One thing that does happen is that it keeps reopening iPhoto asking if I want to import photos from my phone. (a little annoying.) Maybe the cable is bust? It works fine in any other occasion.
Who else has this problem? I need the recording function pretty badly...

I'm having a similar issue. I'm trying to record some games on my iPhone 6 Plus. My Macbook Pro is from 2010 and still running strong. However, I'm getting crashes when trying to record Vain Glory. I can record other games like Grand Theft Auto: San Andreas. Quicktime on the Mac just seems to be crashing with certain iPhone apps. Weird issue.
