When Apple killed development of iPhoto and Aperture last summer, it promised a replacement that would blend the best of the two apps into one solution: Photos for Mac.

Originally promised to arrive in “early 2015,” Photos for Mac is available for the first time in a new developer-only beta of OS X Yosemite. Unfortunately, everyone else will have to wait a little longer to get their hands on it.

Let’s face it: iPhoto sucks. It’s slow. It’s buggy. It’s hopelessly burdened by skeuomorphic elements. It’s just behind the times.

That’s why we were excited when Apple said last year it would phase out iPhoto for a brand new app with a feature set somewhere between iPhoto and Aperture. The successor app was supposed to be available in early 2015, but it appears that Photos for Mac has been delayed.
