    I upgraded my MacPro to Yosemite last night and failed to check the version of Aperture. I always do a software update before I install a new OS over the old one and Aperture did not come up with an update. I thought I was using the version that was usable in Yosemite. I was not.

    I moved from 10.7 to 10.10, so I cannot do the downgrade to Mavericks as best as I can tell. My goal is to get to the Aperture version that works with Yosemite despite Apple no longer supporting it.

    My Aperture was purchased in physical form. It does not appear under purchases in the App store so I cannot convert it to the digital version. I do have time machine backups.

    What are my options?
    Are all images I imported into Aperture in the library? If so, can I just load Aperture to another Mac that I have and load the library there? I'd have to give up Aperture on my MP, but I can live with that. I just need my photos.

    Can I downgrade from 10.10 to 10.7, without some funky fancy song and dance or can I go to Mavericks without having ever had Mavericks?

    Thanks all.

    Can you install 10.7 on an external disk, run Aperture to update it so it runs with 10.10?

    I've got a couple of spare drives with loads of stuff on them in the machine. I could pull out an external drive and hook it up via USB. Will that allow me to boot?
    I'm unfamiliar with that process as a whole and booting from a USB drive.
    The other thing is if I can run 10.7 from an external drive, would it allow me to launch the app from my boot drive (SSD)?

    External Bootable Alternative To Yosemite

    My Yosemite issues were with Adobe CS 5 (Illustrator).

    My MB Pro Retina came with Mavericks installed, and like an idiot I too, installed Yosemite when it was released.

    Solution. Install Mavericks on an external, along with your software, and you should be good to go!

    Good luck!

    Thanks. I ended up installing it on another machine and just moving the library. I exported all originals to another drive and I await Apple's response on a code to get 3.6 from the app store so I can use aperture once more.
