Aperture not working after Yosemite download
I recently downloaded Yosemite, and now my Aperture does not work due to not being compatible. I do not have the latest version of Aperture in order for it to work. There is a big X over it in the dock. Is there a way to merge the library to Lightroom or is there a way to get recent Aperture updates so that I can continue to use it? I probably could copy the library into Lightroom or Photos, but I don't want to use up double the storage.
