What?! Are you saying they removed batch date/time editing?
You can highlight multiple images and then go image>adjust date/time
But this doesn't work very well.
Image 1 from 1st jan 2000 and image 2 from 2nd jan 2000
Say If I adjust the date of them both together to be 10/1/2010
Image 2 would then be 11th jan 2010. Because it adjusted them both by +9 days, 10 years.
If that makes sense?!
If I'm doing something wrong and there's a normal, less idiotic, typical apple way of doing things then I would like to know
