OSX 10.10.3 has been just released and I immediately migrated my iPhoto library to Photos.
More or less there's everything I'm used to in iPhoto but Apple's removed a useful function: I can't reverse the order by date of an album! I mean, on iPhoto I have some smart album sorted with recent photos on top and older bottom but, by default it would be otherwise. In iPhoto there was a menu voice to set it but in Photos, actually, there isn't.
I tried searching album source file (as a .plist) to modify but I can't find it.
Has some one any idea on how to manage sort options on new Yosemite's Photos?
Best Answer
I sort by date by selecting Albums at the top of Photos window.
Then use the View menu to check Keep Sorted By Date
There isn't any way to reverse that currently and I don't see any indication that they'll do anything other than tell you to scroll to the bottom to see the other ordering.
