The system extension /System/Library/Extensions/Apple iSight.kext is displayed on my mini mac What up with that?

my mac mini ios/x is displaying: The system extension " /System/Library/Extensions/AppleBacklight.kext" was installed improperly and can not be used. What does this mean? Thanks.

Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.

The 30" display needs a DUAL-LINK adapter.

I uploaded that new IOS 8.0 and now I cannot open my mail, Safari, or the new "TIPS" app. Does Apple have some sort of help, other than going to a store that is over 40 miles away?

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.

I have found multitude of articles about moving itunes to external drive or other similar things but I don't want to move itunes from the external drive, just change mini mac machines and have everything in itunes the same..
Thanks

I had already tried that one and got this...
below is screen shot of what is on the new mac mini
and what is on the external drive now connected to the new mac mini..
There are no media files on the mac mini just the library files and on external just media files..
Do I need to copy anything over from the old mac mini ? xml files ? .. the itunes folder on old mini is about 840mb in size which looks to have artwork ect ? .. I am fairly computer literate, but this one has me stumped.. ?
thanks for help

What happens when you try to update using an USB connection

the exact wording? Are you using the latest version of iTunes 11.1.1?

Hello, try disabling graphics hardware acceleration. Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.
You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).
Then perform these steps:
*Click the orange Firefox button at the top left, then select the "Options" button, or, if there is no Firefox button at the top, go to Tools > Options.
*In the Firefox options window click the ''Advanced'' tab, then select "General".
*In the settings list, you should find the ''Use hardware acceleration when available'' checkbox. Uncheck this checkbox.
*Now, restart Firefox and see if the problems persist.
Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:
[[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]]
[[Upgrade your graphics drivers to use hardware acceleration and WebGL]]
Did this fix your problems? Please report back to us!
Thank you.

You got me experimenting ... and it was viewing the display with the green button (rather than amber) on the left that revealed the menu bar. Hovering didn't do it. Thanks for your help. First time in Apple Support.

Hi
Magic solution - NO
Some thoughts - YES
Is the iPhoto Library still where it was previously (or on external Hard Disk - now turned off) ?
One approach might be to - Repair iPhoto library (but this takes hours - so try below first)
Trouble-shooting guide
When iMovie doesn't work as intended this can be due to a lot of reasons
iMovie Pref files got corrupted - trash it/they and iMovie makes new and error free one's
problem in iMovie Cache folder - trash Cache.mov and Cache.plist
Creating a new User-Account and log into this
This forces iMovie to create all pref. and cache files new and error free
Event or Project got corrupted - try to make a copy and repair
a Codec is used that doesn't work (even though iMovie and/or iDVD tries to / they fail in the end)
version miss match of QuickTime Player / iMovie / iDVD
preferences are wrong - Repair Preferences
other hard disk problem - Repair Hard Disk (Disk Util tool - but start Mac from ext HD or DVD)
External hard disks - MUST BE - Mac OS Extended (hfs) formatted to work with Video
( UNIX/DOS/FAT32/Mac OS Exchange - works for most other things - but not for Video )
USB-flash-memories - usually do not work
Net-work connected hard disks - usually do not work (most often not fast enough and WRONGLY FORMATTES as DOS etc)
iPhoto Library got problems - let iPhoto select another one or repair it. Re-build this first then try to re-start iMovie. When iMovie starts-up it first look trough this iPhoto library and if faulty it all Halt’s.
This You do by
First - close iPhoto
Secondly - on start up of iPhoto - Keep {cmd and alt-keys down}
Thirdly - now select all five options presented
THEN - WAIT a long long time (>20 hours are not strange)
free space on Start-Up (Mac OS) hard disk to low (<1Gb) - I never go under 25Gb free space for SD-Video (4-5 times more for HD)
external devices interferes - turn off Mac - disconnect all of them and - Start up again and re-try
GarageBand fix - start GB - play a few notes - Close it again and now try iMovie
Screen must be set to million-colors
Third-party plug-ins doesn't work OK
Run "Cache Out X", clear out all caches and restarts the Mac
Let Your Mac be turned on during one night. At about midnight there is a set of maintenance programs that runs and tidying up. This might help
Turn off Your Mac - and disconnect Mains - for about 20-30 minutes - at least this resets the FireWire port.
In QuickTime - DivX, 3ivx codec, Flip4Mac, Perian etc - might be problematic - temporarily move them out and re-try
(I deleted the file "3ivxVideoCodec.component" located in Mac HD/Library/Quicktime and this resolved my issue.)

I solved the problem by removing the file: 3ivxVideoCodec.component. after that, up-dated iMovie runs ok.
Last resort: Trash all of iMovie and re-install it

An iPod can only sync with one iTunes library. The iPod sees the rebuilt computer as a new iTunes library. To make this computer the syncing computer
- Transfer iTunes purchases:
iTunes Store: Transferring purchases from your iOS device or iPod to a computer
- Transfer other music by using a third-party program like one of those discussed here:
newer copy
- Connect the iPod to the computer and make a backup by right clicking on the iPod under Devices in iTunes and select Back Up
- Restore the iPod from that backup.
Note that the iPod backup that iTunes makes does not include synced media like apps and music.

My youtube app is gone disapeared, whats up with that, did Apple secretly took it out because it can't be deleted?

my youtube app is gone dissapeared, whats up with that, did Apple secretly removed it because it can't be deleted?

It is not gone and Apple did not remove it.
It is either on one of the home screens or in a folder, unless restrictions have been enabled and it was blocked.
Check Settings > General > Restrictions. If Restrictions are enbabled, is YouTube restricted?
If all else fails, Settings > General > Reset > Reset Home Screen layout.
