Yosemite screensaver problem. Constsantly reverts back to National Geographic.

Hi, I'm posting here in case a fix is found (not a workaround involving copying files to the nat geo folder..)

I am dealing with a similar issue with the Yosemite screen saver. All I want is to see my family pics as a slide-show..

It was working fine in 10.10.0 then I noticed recently it was no longer displaying my iphoto library, but the Nat Geo pics.

Now I am unable to select my photo library in the screen saver. Every time I select it the preferences app crashes.

There is an error in the console just before the crash: The bundle "iLMBPhotosPlugin" couldn't be loaded because it isn't compatible with the current application...

I believe the fix for that error is an OS re-install..

However, I can select iPhoto images for the desktop background without any problems..

I suspect a recent update (10.10.1 perhaps?) may have broken something as it WAS working... Before re-installing I'll wait for 10.10.2 to see if it corrects the issue.

Thank you for your courage

This issue has persisted since the first Beta version. Numerous reinstalls have not resolved the issue. As for not being able to select your iPhoto Library, that may be an issue with your iPhoto library. Have you tried rebuilding your iPhoto library?

I'm still not convinced it's a OS X issue totally per say. I'm still mystified as to why my Mac mini works fine with Yosemite. All my family pictures on screensaver. As a matter of fact my family share folder is where I'm pointed and the number of pictures is growing with whole family posting. I use the same screensaver on Apple TV. Never had to change anything. My Macbook Air has the problem we are discussing here. I posted my system processor info hoping it might lead to some insight. I don't think processor is the issue now. I've been comparing graphics, resolution, video memory, etc.

What's interesting is most of the responders in this discussion are level low status like myself. I can't believe some Apple people haven't read this by now and at least taken some interest. If anyone else contacts support again point out this discussion thread to them.

I also have no issue with my Mini. I'm using 10.10.1.

Hmmm. Wireless or wired? I'm still trying to narrow in on the laptops issue. Does anyone have a laptop plugged into Internet and still has problem? I have the MacBook Air and can't try that.

Hi,

@Bradleydad Yes I have tried repairing, rebuilding and fixing the permissions on the the iphoto library. It is odd that I can select iPhoto in my desktop picture setting but not in the screen saver..

Fyi this is happening on an early 2011 MacBook Pro. iLMBPhotosPlugin is the iLife Media Browser

Again this WAS working in 10.10.0.. not sure where or what broke it. I did do an iPhoto library rebuild recently and actually wonder if that had anything to do with causing the problem... I expect 10.10.2 will be out soon and I am crossing my fingers that it will take care of the crashing problem.. If it is not resolved by the OS update I may try the OS re-install.

Wired but not sure that would have any impact.

Bumping this thread... having the same issue. Have tried several suggestions (repairing/rebuilding iPhoto library, deleting all "screensaver" files in the library folder) and nothing works. Not the worst thing in the world, but extremely frustrating!! Copying several photos into the Nat Geo folder sounds like a reasonable workaround, but a workaround nonetheless and not a solution :-(

I'm having the same issue (screensaver reverts to National Geographic). Tried:

1) removing relevant ~/Library/Preferences/ByHost/ files. No help.

2) moving the whole ByHost folder. Nope.

3) making /Library/Screen Savers/Default Collections/1-National Geographic a symlink to my Pictures folder. It just says "No Photos".

Really odd behavior: after I set it to my preferred folder (~/Pictures/cropped macros/) and ticking the "Shuffle Photos" box it works.

Then the system changes it slightly, so they are no longer shuffled. Then it reverts the path back to /Library/Screen Savers/Default Collections/1-National Geographic. So weird that it first makes just a small change.

So far the "Ken Burns" saver seems to be holding my folder preference, but no assurance it will keep that.

Syslog shows some maybe relevant info, some kind of bug in iLife media browser:

Mine's still reverting. What's odd is if I tick both show clock and shuffle photos, first the shuffle gets unchecked, and then the screen saver reverts to national geographic. Other things I tried and some system log are in my last post in this thread.

I spent time with customer support and they told me this is a known issue that's currently being worked on by engineering, so I should look for system updates in the future.

As a stop-gap, he recommended that I copy my pics into a folder and have the screensaver point to that folder instead of using an iPhoto library. I did that... and then the screensaver defaulted to Nat Geo again. So it seems like it's even bigger than how the screensaver links to iPhoto - at least in my case.

I'm just trying to point it to a regular file folder (~/Pictures/cropped macros). So no, that is not a fix.

This problem is intermitent. Sometimes my chosen iPhoto library stays for a day or two and sometimes not at all. I tried the "create folder" fix and that simply reverts back to nat geo. In fact there is no FIX. There is only the workaround, which so far has held no problem, in fact I see no way it could fail as all you do is chgnage contents of (natgeo) folder. The iMac still reverts.

I also agree this is troubling as a "tip of the iceberg" thought.

FWIW My conversation both with Support and at the Genius bar was with two people who did not admit it was a known issue as of late last week.

Glad I did not load Yosemite on wife's macair or she would have blamed me for this. She blames me any time anything on MAC fails ever since I lost a lot of data back in 1995 by backing up aliases for year. Was complete novice and did not realize the desktop alias contained no data.... but I digress.

This is very annoying but my wife found a work-around.

Select iPhoto in Photo Library in Desktop & Screen Saver then don't quit System Prefs, just minimise it.

Works on her MacBook Pro and my iMac.
