Backward Slideshow - why?

A slideshow on your Mac or iPad/iPhone?

On your Mac use a regular slideshow created with "File > New Slideshow". Viewing slideshows from regular albums is still buggy, when sorting the photos manually.

Sorting photos on an iOS device is still not well supported, see: http://web.archive.org/web/20131106105526/http://support.apple.com/kb/HT4221

There's a bug with iPhoto 9.5 and Mavericks in that slideshows from Albums do not play correctly if they are sorted manually. Only photos that have been sorted by date, keyword, rating or title will play from albums correctly.

To have a slideshow with photos sorted manually use the slideshow mode in iPhoto.

Send a bug report to Apple via http://www.apple.com/feedback/iphoto.html.
