How do I fix this (cheaply)?
My Powerbook fan has been quite loud for the past few months, so I bought a bottle of compressed air to spray off any dust that may have been surrounding it. Not only did it not work, it made my computer WORSE.
The colors on my screen are screwing up worse than you would believe. I've never seen this happen before (on any computer), so it's quite difficult to explain. I took this screenshot with Preview to give you an idea:

Notice that stupid crap in the upper left-hand corner. Now picture that blinking all over your entire screen, keeping you from working/reading/ANYTHING! When I change my desktop background, it momentarily fixes it. The same goes for dragging and highlighting with my mouse. Weird, huh?
Anyway, it's gotten consistently worse over the past couple days. Did I spray the wrong computer part? How can I fix it? Please help, this is the most obnoxious computer problem I've ever dealt with.
Thanks in advance.
Hi, mOrdoth. It looks as though you have a video hardware problem, and if that's the case, the fix won't be cheap. Run the Apple Hardware Test that's available on one of the discs that were originally shipped with your computer, and let us know exactly what it tells you (the report will be cryptic, not necessarily plain English).
If the test reports no problems, connect an external monitor to the Powerbook and see whether the same problem appears on it, or whether it's limited to the built-in display. If only the built-in display shows the video hash, the problem is in the video cable from the GPU to the LCD panel or in the LCD panel itself. Apple Hardware Test can't detect problems in those.
It would also be helpful to identify your Powerbook model precisely for us. This article will help you do that.

"You cannot install iWeb Update on this volume. A qualifying copy of iWeb was not found in /Applications." How do I fix this?
Version 2.0.4 is iWeb 08 and direct publishing via ftp is not available in iWeb 08 and never has been. You have the option of publishing to MobileMe, but you can publish via ftp, but you need to select the option publish to a local folder instead and then upload using Cyberduck, which is a free and dedicated ftp client.
If you want the inbuilt ftp function, then you will need to upgrade your iLife package to either iLife 09 which contains iWeb 09 or iLife 11, which also contains iWeb 09. For this, you need to purchase both of these packages. Either go to Amazon and try and get a copy of iLife 09 more cheaply or purchase iLife 11 directly from the Apple store.
This is what you will need to do and iWeb 08, which is the version you have, never has had built in ftp so that option will never be available to you unless you upgrade which you will have to pay for. Upgraded and updates are different things. Updates are just your normal run of the mill software updates and address bug fixes etc., whereas you will need to pay for full upgrades to other packages such as from iLife 08 to iLife 09 or 11. -
when I request a software update, i am told my software is already up to date but I know it's not. how can I fix this?
The pre-2006 iMacs this forum covers cannot run any higher than OS10.5.8, and Apple pretty much stopped pushing out any updates for anything other than the current version.
If your iMac is a newer model (covered here: iMac (Intel) forum) you can run at least 10.6.8, available for purchase rather cheaply here:
http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard
and it's possible you can run higher depending on your iMac variant. So find your iMac variant, please do "About this Mac" from your Apple menu and, in the resulting window, click the "More Info" button to get this screen:
Please tell us the code name ans number for your computer in the line I've indicated with the red arrow. For an iMac, it will either be in the format, "PowerMacX,X" or "iMacX,X" depending on the age of your iMac. The trailing numbers where I put Xs will help us help you determine what exact variant you have and what upgrade options are available.
Also tell us how much RAM is installed. Newer OS versions often need more RAM that older iMacs shipped with. -
Some of the songs I bought from iTunes will not sync to my iPhone. They show up on my phone, but the letters look faed and I can't play them. How do I fix this? I tried restoring my iPhone and it didn't work.
Sorry, I meant the letters look "faded" not faed.

CD's purchased from iTunes but uploaded to iTunes do not show up in the music folder on my Apple TV! How do I fix this?
You would need to make sure you're accessing the Computers icon. If you are under the Music icon, that will be accessing the cloud and only show iTunes purchases (unless you subscribe to iTunes Match)

Can someone please let me know how I can fix this error and open my Lightroom? Thanks.
You might be quicker help posting in the LR forum rather than the ACR forum, but I believe the way to fix this is to delete the preview cache.
Find your catalog folder.
Close LR.
Within the catalog folder, delete the FOLDER called Catalog-Name Previews.lrdata
Start LR. -

We have our family sharing one itunes account. we have 3 iphones, 2 macbook airs, 2 ipads and 1 mac. I am not sure how we even got started on the icloud but somehow we did and everything is a mess. The ipads are showing the text messages, the contacts are all combined, the apps that my duaghter downloads are appearing on all devices. how do we fix this so contacts are not shared, messages are not shared and apps are not automatically synced to all devises?
You have two different issues going on. You are getting each other's messages because you are sharing the Same Apple ID for iMessage. This can be corrected by going to Settings>Messages>Send & Receive on add the devices and doing one of the following:
Either uncheck the email address shown under "You can be reached by iMessage at" on all of your devices; or
If you want to continue to receive iMessages at this email address on one of your devices, on all of the other ones tap the Apple ID at the top, sign out, then sign back in using a different Apple ID (so all devices will be using a different Apple ID for iMessage). Note: you can continue to share an Apple ID for purchasing from the iTunes and App stores. It does not need to be the same as the ID you are using for iMessage, FaceTime and other services.
The second issue is that you are sharing the same iCloud account on your devices. When you do this any data you sync with the shared iCloud account such as contacts is merged and will appear on all devices connected to the account. To fix this you both need to have separate iCloud accounts (you can continue to share the same Apple ID for purchasing from the iTunes and app stores).
First decide which device(s) will be keeping the current iCloud account. On the one(s) that will be changing accounts, if you have any photos in photo stream that in your camera roll or backed up somewhere else that you want to keep on the device(s), save these to the camera roll by opening the photo stream album in the thumbnail view, tapping Edit, then tap all the photos you want to save, tap Share and tap Save to Camera Roll.
Once this is done, go to Settings>iCloud, scroll to the bottom and tap Delete Account. (This will only delete the account from this device, not from iCloud. The device(s) that will be keeping the account will not be effected by this.) When prompted about what to do with the iCloud data, be sure to select Keep On [iDevice]. Next, set up a new iCloud account using a separate Apple ID (if you don't have one, tap Get a Free Apple ID at the bottom). Then turn iCloud data syncing for contacts, etc. back to On, and when prompted about merging with iCloud, choose Merge. This will upload the data to the new account. Repeat this process for all the devices that you need to migrate to new accounts.
When finished, to un-merge the data in your accounts you will have to go to icloud.com on your computer and sign into each iCloud account separately and manually delete the data you don't want (such as deleting the other person's contacts from your account, and vice versa). -
Back then when I had the older update with iTunes i never had this problem with trying to put my mp3 files of music into my iTunes library. Now it doesn't want to be put into the library. Once I try to drag the music file to the iTunes library nothing happens, it just keeps showing a cancellation sign with my mouse. So how can I fix this?
Hi William.
The problem is probably that the index is corrupt and you need to completely re-create it rather than rebuilding individual mailboxes. I have no idea what the situation really is now after having tinkered with the contents of ~/Library/Mail/, though, so the following procedure may or may not work.
Verify/repair the startup disk (not just permissions), as described here:
The Repair functions of Disk Utility: what's it all about?
After having fixed all filesystem issues, if any, and making sure that there’s enough space available on the startup disk (a few GB, plus the space needed to make a backup copy of the Mail folder), try this:
1. Quit Mail if it’s running.
2. In the Finder, go to ~/Library/Mail/. Make a backup copy of this folder, just in case something goes wrong -- e.g. by dragging it to the Desktop while holding the Option (Alt) key down.
3. Locate Envelope Index and move it to the Trash. If you see an Envelope Index-journal file there, delete it as well.
4. Open Mail. It will tell you that your mail needs to be “imported”. Click Continue and Mail will proceed to re-create Envelope Index -- Mail says it’s “importing”, but it just re-creates the index if the mailboxes are already in Mail 2.x format.
Note: For those not familiarized with the ~/ notation, it refers to the user’s home folder, i.e. ~/Library is the Library folder within the user’s home folder. -
My Outlook/iCloud calendar invites to others appear to work on my end and sync with my PC and mobile, but when other people "accept" the invite, it will not populate/add in to their calendar. How can I fix this without turning off iCloud?
I am at a new office that uses Outlook (not Outlook Exchange) which does not sync with my mobile... I just got iCloud set up on my PC to sync my contacts, calendar, reminders, etc... The sync worked (not without flaws, but the other issues seem solvable... I think), so that i can now see all my appointments on both my phone and on my PC. The problem I am having is that iCloud moved all of my calendar items from Outlook into iCloud calendar and now when I send out meeting/calendar invites the recipients may accept them, but the meeting does not get added to their calendar. This is a huge problem and may mean that i need to turn off iCloud.
Does anyone know how to fix this?
Thanks!I am replying to my own post here as I seem to have fixed the problem.
I do have some calendars that are shared. Some of those are shared with users who have time zone support turned on. So i activated time zone support on my iphone, then deleted my icloud subscription. I then signed in to icloud again and voila... problem solved.
It is a weird one as the other calendar views were always fine and when you opened an event that appeared in the wrong day (on list view), the correct date of the event was shown in the information...

My iPod touch is stuck on one song in my play list when in the shuffle mode. How do I fix this to shuffle through all the songs in that playlist?
If you go to the Now Playing screen, the Repeat control is the the arrowed racetrack icon on the left side right below the scrubber bar. Tap the icon to change. It is white when Repeat is off.

This was the first purchase I made.Are you following these instructions?

My wife's nano no longer is recognized by Windows but my ipod touch is? How can I fix this?
My wife's nano no longer is recognized by Windows but my ipod touch is? How can I fix this?
My iPod touch is always recognized by my Vista Box...using the same USB cable and port my wife's nano isn't detected anymore. Since Vista can't see the nano iTunes can't see it either. When I try my wife's nano I get the message:
"One of the USB devices attached to this computer has malfunctioned, and Windows doesn't recognize it. For assistance in solving this problem, click this message"
I thought her nano wasn't charged enough but I've charged it for hours and this doesn't make a difference. It used to synch like my ipod touch but it stopped working about a week ago. My wife's nano still holds songs and works it just can't be recognized by Windows. I even checked if the Apple Mobile Device app was running and it was and I stopped it and restarted it. Didn't make any difference. Any ideas?
