External keypad won't work after installing OS 7.

External keypad won't work after installing OS 7. I have a "Zagg" keyboard that won't pair now to OS 7,...Why?

They do work. I have one and mine is working. Have you tried to reset your iPad? HOlding down teh sleep and home keys until it reboots then try pairing again.
A slightly more drastic thing is to go into the settings and reset all settings. THe downside, you will need to retweak your device but it can help fix keyboard glitches.

Printer won't work after installing mountain lion?

printer won't work after installing mountain lion?

Assuming you've first checked Software Update to see if there are any updated drivers and it's still not working, you could try resetting the printing system.
System Preferences>Print & Scan, Control+Click or Right Click on a printer on the left and select 'reset printing system'. All printers will be deleted and need to be added again.

External monitor no longer works after installing iLife '09

Before, the external monitor (Apple Cinema HD display) connected via DVI to Mini-DVI adapter was working fine. However, after installing iLife '09 and restarting, the iMac will no longer detect the external display attached to it. I even tried installing a different (but same model) display but it still will not detect.

I'm not sure how installing an application would cause that to happen. Have you shut down (powered off) the iMac completely, and then restarted, since this problem occurred?
Some display settings are stored in PRAM, so if you have not already, try resetting PRAM
http://support.apple.com/kb/HT1379
If that does not help, you can try disconnecting the iMac from power and reconnecting it, using the reset SMC (power management) procedure.
http://support.apple.com/kb/HT1543
When you reconnect it, initially connect the iMac to a wall outlet, by itself. Leave all peripherals disconnected, except for your USB keyboard/mouse. Make sure it is working properly, then connect only the external display.
If it still does not work, as a test, start up with your Mac OS X installation disc. You are not installing anything, but note if the second display is displaying the background image or not when you are booted from a different system.

Touchscreen and trackpad won't work after installing new OS

i want to ask why that after i upgraded my os, and during the start up when i have to scroll down the aggrements text my trackpad and my touchscreen won't work. is that any way to solve this problem? i beg you to answer my question please. i would be very grateful. thanks

Did you actually upgrade to OS 7.0 or to OS 7.1?
What OS were you previously on that you want to downgrade to?
For the application in question, go to Options > Device > Application Management. Find the app and delete it.
Now, go back to AppWorld and install it again and see if it works correctly.
For most apps that I know of, if they worked correctly on OS7, they will be fine on OS7.1

Canon MX 860 scanner won't work after installing Mt Lion

After upgrading my IMac to Mountain Lion v 10.8 my wireless Canon MX 860 scanner function won't work. The printer works. When I try to start the scanner either from the keyboard or the scanner I get an error message: MP Navigator EXquit unexpectedly.
I downloaded and reinstalled the scanner driver
mac-mx860-14_11_4a-ea8_2-1.dmg
and restarted and it still doesn't work.
any other suggestions?
thank you

You may also need to update MP Navigator to v2.1.3. If you are using an older version then trash that version before installing the latest version.

External Hard Drive not working after installing mavericks

After installing mavericks, I hooked up my external hard drive,
and it would not show up on the computer. Tried checking if
it showed in utilities, also a no show.
Should I uninstall the ntfs software which is a few years
old and instal a newer version?
Looking for a solution which doesn't involve reformatting my nearly full
1TB EHD, please :)

I think I have version 10.8.6 of mavericks, not 10.9.

Premiere Pro won't work after installing windows 8.1

Hi,
I have recently installed Windows 8.1 on my laptop. After the installation was completed I got an error message when I tried to open Premiere Pro CC. The error message says the program can't start because MSVCP110.dll is missing and that I should reinstall. I don't want to reinstall as I'm worried about losing work. Any help would be much appreciated.

Hi,
Firstly I must apologize for not replying to this earlier. I have done as suggested restarting my computer after installing but I still get the same error message.... I know I've left this response very late but any help would be much appreciated.

IPhoto won't work after installing iLife '11

I installed iLife on both my work computer which is a '11 iMac and my personal computer is a '12 MacBook Pro. After installing I can't run iPhoto on either computer? When I try to open it on my computer it gives me a window that says "You can't open the application iPhoto because it may be damaged or incomplete." I've tried running updates and looking on forums that suggest 9.1 update but it will not allow me to upload it, it says I need a previous version? I'm not sure what is going on but it is very frustrating

Open Finder, go to Applications folder, delete iPhoto and reinstall it again. Finally, open  > Software Update and update iPhoto until you have iPhoto 9.4.1

My Canoscan 8400F won't work after installing Yosemite

I updated my IMac to OSX Yosemite 10.10 and now the Canoscan 8400F won't work.The toolbox won't open and none of the buttons will work. I've tried to find a new driver but they aren't making them for this system. Do I have to buy a new scanner?

I recently upgraded to Yosemite and my Canon LiDE 60 scanner stopped working. It is not on the Canon list of scanners supported by Yosemite. I downloaded and installed the LiDE 60 driver v11.1.3.1 which was the one listed for OSX 10.6, the last OSX version to list a driver. Still no luck. I eventually noticed that I currently have Canoscan Toolbox v 5.0.1.4, presumably updated along the way. Once I downloaded and installed Canoscan Toolbox, v 4.9.3.4, the one also listed for OSX 10.6, things are back to normal. You need the old driver PLUS the older (then current) version of Toolbox. This works for the LiDE 60, but the logic would apply to other older Canon scanners. Good luck.

Time Machine won't work after installing Mountain Lion

After installing Mountain Lion, I am unable to restore a file from time machine. I click on the time machine icon. It shows the bakups, I click on a previous backup but the screen doesn't roll back to the date. It only shows the current files. Example: I am trying to restore an email that was lost. I try to do a restore and it shows emails up to today even though I am asking for a back-up from a month ago.
Bob

Sorry, but I'm still not sure what you're seeing.
Are you starting from Mail, per the blue box in Time Machine - Frequently Asked Question #15?
Are you trying to restore emails from a mailbox in the "On My Mac" section?
Do the older backups not appear in the TimeLine at all, or do they appear but are faded-out?
Posting a screenshot might help.

External drive won't boot after install?

I tried installing mountain lion onto an external SSD drive. At first it worked, using my USB install drive and selected my external drive as the target. All the files are copied over and asked me to restart. However, after restart all it did is booted back into my internal drive OSX. Even if I held down the option button it won't allow me to boot the external drive. Any ideas? I'm doing this from the retina macbook pro.

Install or Reinstall Lion/Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Partition and Format the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your external hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
Reinstall Lion/Mountain Lion: Select the External drive, then select Install Lion/Mountain Lion and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
because it is three times faster than wireless.

Ipod touch won't work after installing a new app.

Hi!
Last night, I decided to install a new "Alarm clock," app and test it out by setting it to ring a minute later- what a BIG mistake, because during the time it was supposed to ring, it made my Ipod touch completely crash instead. For the past few hours all it's been doing is flashing back and forth between my homelock screen (with the "slide to unlock," bar at the bottom) and the Apple logo, with the round 'processing' image infront of it.
I have tried many different things to get it out of this funk but nothing has worked! I tried resetting the Ipod by holding down the menu and power button, the screen went black temporarily, didn't show the "slide to power off" bar and then just reloaded with the same two flashing images. I tried restoring it, but it wouldn't restore, until I did a special reboot that I read about via online boards- where you have to hold the power + menu buttons for 10 seconds, then release the power button whilst holding just the menu button for 10 seconds- but, whilst the Ipod did go through the whole restoring process thereafter, it didn't manage to sync up.
Now, not only does my ipod STILL flash back and forth between those two images. I keep getting an error message of (0xE80000001)! I used a different cable to try and sync up, but the blasted thing still won't stop flashing back and forth between those two images, and the ipod is not being recognised by itunes so the ipod keeps beeping, in and out of itunes and won't sync!
My ipod isn't 'jailbroken,' I haven't touched it's software or altered it in any way, to how it was sold to me. I would've liked to have brought it back the the Apple store to be looked at, but I don't think they'll help me because the top left hand corner of my Ipod is completely missing after my niece dropped it a few months ago- the Ipod still worked (up until I installed the **** alarm app) perfectly well until now!
Also, I have a mac, so any tips on how to access/help/fix this problem would have to have instructions for a Mac OS not Windows please!
Many thanks!

I keep getting an error message of (0xE80000001)!

External Monitor no longer working after install of 10.4.3

Hi:
I am having some major issues after the last update with my external monitor, Dell 1905FP. I have a PowerBook G4 15in, 1.5 processor. Prior to the update I had no issues utlizing the monitor while closing the clamshell but after the update I was unable to utilize the rotation to portrait view on my monitor, with the clamshell closed. It would work on standard view to close the clamshell and then wake the computer utilizing a USB device or bluetooth keyboard.
I decided to after repairing permissions, disk utility, utilizing a DVI and the Analog cord with adaptor, creating a test user account, resetting PRAM and NVRAM and such to try reapplying the combo updater. This further broke the problem as I was unable to close the clamshell and wake the computer up to utilize the external monitor, even in standard (landscape view). When I do close the clamshell with the external monitor hooked up and then wake the computer with my mouse or keyboard the external monitor does power on and shows a lot of static and such not allowing me to see my desktop, but I can see the mouse cursor.
The external monitor works just fine, so long as I leave the lid open and if it goes to sleep with the clamshell open, it wakes just fine and the monitor works. This problem only occurs when I close the clamshell. I prefer the clamshell closed because it gives me the full screen that I desire in portrait mode due to the great amount of writing I do (it allows me to see a full 1 1/2 pages of text in Word while writing).
Another monkey wrench is that I was able to use another monitor, a 17in CRT and it worked just fine, I could close the clamshell and wake the computer utilizing my mouse as I have always been able to. However, I do not believe the Dell monitor is broken, given it will work with a PC laptop perfectly.
Does anyone have a clue on what this issue could be and a possible fix. I have used my Mac exclusively for a little over a year and I am just learning how to troubleshoot this. My thoughts would be to throw away the preferences in the system and then try hooking up the monitor again (as if it were a new monitor)but I have no idea what preferences to throw away.
Any help is appreciated!
Michelle

I answered this question on my own. I was able to utilize Pacifist and reinstalling the video card drivers and display profiles. Now everything works as it should.

Music won't play and sound won't work after installing ML

I installed mountain lion on my 3 year old mac book. now my music doesn't play on itunes. the pause button is visble but the music progress bar is not moving. there is no sound either. the horn in the sys bar on top is greyed out nor will the external speakers work on other sound makers like you tube, etc. any ideas? thanks

1. Open Activity Monitor.app (Applications > Utilities > Activity Monitor.app)
2. Select ‘All Processes’ from the drop down menu next to the search bar (called ‘Filter:’) and type in ‘coreaudio’.
3. Select the process name and click the ‘Quit Process’ button at the top. Chose 'Quit' or 'Force Quit' from the resulting dialogue box.
Any improvement?
