Bad Luck fellow Mac -ers, under Mac OS X Mountain Lion ( to quote from "OS X Mountain Lion - the Missing Manual", page 352):-
" Note: You can no longer install different screen-saver styles. And you no longer have a choice of different presentations for you own folders, like the amazing Collage mosaic (which built up one giant photo by using hundreds of smaller photos as individual pixels."
I find this type of functional curtailing of our cherished OS X by faceless Apple apparatchiks quite sinister. It generates echos of "MAD" magazine's Spy Vs Spy scripts, albeit without the humour. I had always believed the people at Apple valued the interlect of their users and revelled at possibilities to stimulate our cerebral processors. Perhaps I was somewhat "glossy eyed" OR we may have been infiltrated by our OS opposition. Beware !!
Interestingly, being a Dr. Who nerd, I downloaded a free, 32 bit screen saver application (Dr. Who Screensaver) from a BBC site which I WAS ABLE to add to the relevant System/Library/Sceen Savers folder. I could then select that screen saver in "System Preferences/Desktop and Screen Saver/Slideshows" which then loaded when scheduled BUT it flickered on screen with a message that a later version was required.
As the screen saver was free, I felt sure that the BBC sources would not be interested in updating the codes (or as may be) so I could run their screen saver on my beloved iMac. I'll try contacting the copyright owners Screentime Media for further help.
The point is - according to the Manual, I SHOULD NOT HAVE BEEN ABLE to get as far as I did. Does anyone have any thoughts, please?
I hope this helps.
