I think that giving up on Aperture and accepting its demise is not our only option, Aperture is by far the best digital photo application that Apple (or indeed any other software developer) have created and as such, must not be allowed to disappear.
If we all create a groundswell of opinion we can persuade them to reinstate this Rolls Royce of an application. Lets unite, and rise up to remind Apple that Adobe cannot be the provsole digital photo platform on the planet.
Unfortunately you will have to change at some point. Some folks say that they won't update the OS and just keep using Aperture, but one day your Mac will break and you'll need to replace it. At that point you will have to use a new OS, and if Aperture won't run on that, then you will have a crisis on you hands.
Now is the time to evaluate alternatives and select one, so that you can do the transition is an orderly and managed fashion. If you think that might be too stressful, then imagine the stress when you're learning a new OS on a new computer and a new app all at the same time, and you can't even access the Aperture Library.
Adobe are not the only people with apps in this space, tho probably LR is the nearest to Aperture, and has a migration tool. But there are others: Capture One, Corel AfterShot, ON1 PhotoRaw, Luminar promises a new DAM app in 2018 and so on.
Frankly, I don't see that you have a choice. Do it now when it can be managed, or later when it's a crisis. That's your choice.
Sorry about the typo: "Aperture"
Don't give up on Aperture
