Apple's Photos app for Mac is coming this Spring. Despite previous reports of delays, the new app, announced at WWDC 2014 alongside OS X Yosemite and set to replace iPhoto and Aperture, is now available for developer testing in the first beta of OS X 10.10.3.
There's a new page at Apple's site showing off all of the new app's features.
While iCloud Photo Library has been available on iPhone and iPad since iOS 8.1 launched (albeit with a beta tag), I've been hesitant to throw all of my photos into it. I'm still very much reliant on Dropbox for all of my cloud storage, but I hope to be able to offload my photos into the new Photos app in the near future. However, given iCloud's reputation for lack of reliability, I think I'll wait to see what others say before taking the jump.
Weirdly, many members of the press got ahold of OS X 10.10.3 with the Photos for Mac app ahead of today's announcement — you can read hands-on impressions from Re/code, WIRED, The Wall Street Journal and The Verge.
