Aperture 2 has been released! It is faster, more powerful, has better workflow and layout. Unfortunately Aperture 2 isn’t in Apple stores yet, and Apple’s online store doesn’t seem to offer a download option for Aperture. There is, however, a downloadable trial. But the downloadable trial can’t upgrade an existing Aperture library. So here is how you do it:Go into your <code>/Applications/</code> folder and rename your existing copy of Aperture to “Aperture Old Version”. Download the trial (you’ll need a trial code which will be sent by e-mail). Start up the trial version using the trial code. Then click the “buy” button. You’ll be given an option to get a downloadable serial number. Upon buying it you’ll instantly get a code that will turn the trial into the full version, along with the ability to upgrade an existing library. Close Aperture, delete the “trial library” that was created, and then restart Aperture. It’ll ask for a library. Point it to your Aperture 1.5 library. It will upgrade your library and you’ll be on your way!
