Screen Saver keeps defaulting to National Geographic no matter what I set it to.

I have repeatedly set my screen saver preference to Photo Library, but the computer keeps resetting it to National Geographic. I have tried setting the screen saver to other settings, such as Aerial or Cosmos, just to see what happens, and it always goes back to National Geographic.
Help! Is this just a glitch? Or am I missing something...?
I am starting to hate National Geographic.

Issue for many. Look through this forum for the discussions.

My 2014 iMac with Yosemite keeps powering down overnight. It reboots fine. It did not do so before the Yosemite update. Help!

my 2014 iMac 27" powers down overnight after I installed Yosemite. It did not do so prior to the update. I just want it to sleep. How can I fix this? Thanks.

One last thought about a mac taking long to boot...try resetting the PRAM, that usually works.
1Shut down your computer completely. If you cannot access the shut down menu, you can hold the power button down until the machine shuts down. If this does not work, you can unplug it from the wall, but this is not recommended unless there is no other way to shut it down.
2Locate the "Command," "Option," "P" and "R" keys on your keyboard. The Command and Option keys are generally located directly to the left of your space bar. You will need to press these keys all at the same time, so be prepared to do so
3Turn on the iMac. Immediately press and hold down the "Command," "Option," "P" and "R" keys on your keyboard. This must be done before your computer displays the gray startup screen, otherwise it may not work.
4Continue holding the keys down until the computer restarts itself again, and you hear the startup chime. You may then release the keys, and your computer will boot up to your login screen or desktop

CS4 Design Premium on a new iMac with Yosemite

I am having trouble installing CS4 Design Premium from the original disks on a new iMac with Yosemite. It keeps going to an upgrade request and won't accept my serial number.
Any ideas on what I am doing wrong?

I am not a Mac person but it sounds to me CS4 is too old for Yosemite.

Error 150:30 on new iMac with Yosemite

I upgraded from an 8-year old iMac to a new iMac with Yosemite. After migrating everything over, I can't run PSE because it said some files were missing. I re-installed the software using my original disk. Then I got a 150:30 Error. Help!

You can never, never migrate an installed copy of PSE. It's just too complex and has bits scattered all over your hard drive. Unfortunately, one of the things that does migrate is the file that tells PSE it's not on the authorized drive anymore. To deal with this at this point you will need to download and run this:
Use the CC Cleaner Tool to solve installation problems | CC, CS3-CS6
After which you can go around and manually remove all the bits of PSE that you can find, not only from Applications, but also from the library at the top level of your hard drive>application support>adobe, and your username>library>preferences. Spotlight will not help you here; it's programmed to skip these kinds of files. If you need help finding those libraries, post back.

I can't download the latest security update to my iMac with Yosemite 10.10.1

I can't download the latest security update to my iMac with Yosemite 10.10.1

Hi mesuno. I can't download the update either. When I click on "Update" I see the download progress bar for only a fraction of a second. Then I get a message in the "updates installed" area saying that the update has been installed. Then the Security Update notice returns and so does the "Update" button. Then I press "Update" again and the same thing happens. I can do this ad infinitum.
The system seems to be confused. I have several entries in the "installed" area saying that it has been installed, but still the "Update" button persists. When I check with "Sytem information" there is no record of the installation.
Is there something wrong with the App Store app, or does anyone else have a better idea?

CS4 transferred to an iMac with Yosemite OS, installed Java update, still won't open.

CS4 transferred to an iMac with Yosemite OS, installed Java update, still won't open. Should I reinstall from disks or can I get a free upgrade to CS6?

there's no free upgrade.
you 'transferred' or you properly installed cs4 using the installation files?

Make Your Own Yosemite Installer
After downloading the installer you must first save the Install Mac OS X application. After the installer downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the installer. Move the copy into your Downloads folder. Now you can click on the Install button. You must do this because the installer deletes itself automatically when it finishes installing.
2. Get a USB flash drive that is at least 8 GBs. Prep this flash drive as follows:
Open Disk Utility in your Utilities folder.
After DU loads select your flash drive (this is the entry with the mfgr.'s ID and size) from the leftside list. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
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.
Set the format type to Mac OS Extended (Journaled.)
Click on the Erase button.
Open the Terminal in the Utilities folder. Copy and paste the following command line in its entirety into the Terminal window.
sudo /Applications/Install\ OS\ X\ Yosemite\ Developer\ Preview.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Yosemite\ Developer\ Preview.app --nointeraction
Press RETURN, enter admin password (will not echo to the window) then press RETURN again.
You need to have the installer in your Applications folder or change the paths in the above command line.
Wait for the process to complete which will take quite some time.

Messages will not work on 2009 21.5 iMac with Yosemite

I have a 2009 iMac with Yosemite 10.10.2 and cannot get messages to work with a good AIM account, any ideas?

In order: No, and I don't know for sure, but strongly suspect no.
Only the 27" models have video input, and things like TV tuner/capture cards are always going to have a lag that is unacceptable for gaming. Even if you had a 27", it wouldn't work very well for use with a game console. I've been there, done that, with just about every possibility you can think of.
For a time I had an Xbox, PS2, and GameCube all connected to a Dell monitor and the sound chained through my computer. It worked, but it was a very convoluted and fragile system. The best thing I ever did was just buy a surround sound receiver and TV for my game consoles.

When I set my screen saver to iLibrary it defaults to national geographic,why and how can I stop it

when I set my screen saver to iLibrary it defaults to national geographic,why and how can I stop it

Back up all data. Quit System Preferences if it's running.
Triple-click anywhere in the line below on this page to select it, then copy the text to the Clipboard by pressing the key combination command-C:
~/Library/Preferences/ByHost
In the Finder, select
Go ▹ Go to Folder...
from the menu bar. Paste into the box that opens (command-V), then press return. A folder named "ByHost" should open. Look inside it for a file with a long name that begins "com.apple.screensaver". There may be several such files. Move them all to the Trash.
Log out or restart the computer. Test. If the problem is resolved, empty the Trash and recreate your settings in the Screen Saver tab.

My wife and I share an iCloud account for photo library and iCloud drive mainly for our family photo management, but we use different accounts for iMessage/facetime/calendar/etc. With Yosemite, I can't use continuity/handoff without dumping the photo

my wife and I share an iCloud account for photo library and iCloud drive mainly for our family photo management, but we use different accounts for iMessage/facetime/calendar/etc. With Yosemite, I can't use continuity/handoff without dumping the primary photo iCloud account and thus our shared photo system. We are running yosemite OS X 10.10 and iOS 8.0.2... Is there any way to do this?

I have a MacBook Pro running mac osx 10.8, Screen saver keeps reverting to national geographic photos.

Just found this solution on another website. I tried it and it works. No more polar bears and Savannahs!
Apparently if you put it in the folder called "Desktop Pictures" it will work.
So, copy whatever folder of pictures you would like to use as your screensaver and then go to:
Macintosh HD>Library > Desktop Pictures
Paste your folder into this folder called "Desktop Pictures".
You may have to enter the administrator code (the password you use to open your mac usually).
Then, go back to System Preferences, go to Desktop and Screensaver, click on the Screensaver tab on the top, go to the drop down menu beside "Source" (under the picture) and click on "Choose Folder". Navigate to the Macintosh HD>Library>Desktop Pictures and then click on the folder you just pasted in there. Click "Choose" and you're all set.

My new iMac with Yosemite displays photo icons with a white border. How can I remove this border?

How can I remove the white border/'frame' around the photo icons, which I store in folders other than iPhoto?
My computer is an iMac 27" (Late 2014 5K Retina display) with Yosemite 10.10.3.
The border does not exist on any photos /images created on my MacbookPro (Lion) or any earlier computers. It appears after importing to the iMac and only then after saving in either Preview or Photoshop Elements.
I have looked in all "Preferences" but could not find how to remove the border.
Any advice will be gratefully received.

Thank you for the reply. I wanted to wait awhile in order to ensure that this corrected the issue. For a brief while, it did! However, it did not take long before the screen began once again hijacking my home button presses. This occurs even with Firefox removed from default applications ( triple-checked ).
This never happened before version 35.

Getting Multiple user iMessage & FaceTime on my iMac with Yosemite

My son has an iPhone 5c running iOS 8.0.2.
I've just upgraded my iMac to Yosemite.
I'm getting my iMessages and Phone calls with the new Yosemite OS, but I'm also getting my sons iMessages and FaceTime requests.
Only his iMessages and Facetime, no Phone calls, no Text messages. I tried turning off his Bluetooth, thinking that was the issue, but it isn't.
This must be a settings thing, but I cannot figure it out.
Any help will be highly appreciated.
Thanks in advance.

Exactly what did you do?
Open Users & Groups preferences.
Click the lock icon and authenticate.
Select the account to delete then click on the Delete [-] button.
Select the option to delete immediately. Do not select erase securely.
If you've already deleted the account using secure erase, then you cannot change that. You will have to wait until the process is completed which may take days depending on how much data was in the account.
