Still using

[Clearair]

Still happy to use Aperture. Still working and using DNG can import from new camera. If I pixel peep then maybe there are better raw process software solutions, but honestly would 99% of non anorak non professional photographers notice?
When and if I start to use another I plan to keep Aperture as an archive of my work until now and library of future files in Tiff and DNG. 
If there was going to be a powerful DAM from some other developer it would be here by now. The mob dump everything on social media and the professional has had to move on. So where is the $$ for something as complete as Aperture now from someone other than Apple. I will never forgive Apple for failing to continue support for what they sold originally as a professional application.

Not sure but Apple has the ability built in the system to deal with the raw files ( Preview / Photos).
Do not understand why they did not let it communicate with Aperture. Can't be much work.

I agree with the sentiments expressed.
I was very nervous that I would have to get a new DAM (no, not Lightroom!) when I upgraded to the X1D. I was presently surprised that Aperture has no problem with the new Hasselblad raw files.
Unfortunately no developer has seen fit to address the glaring need for new DAM. All they do is churn out more and more raw processors.

The least that Apple could do is to make Photos useful. It doesn't even have 5 star ratings.
Probably time to complain to Apple again.
I have over 100,000 photos in Aperture now but the good news is that it still runs and fairly fast too. I need to try it on Mojave once I have some confidence with that.

I find that my very large Aperture library takes a very long time to load.  The "processing" indication runs for 10-15 minutes after launching.  If you try to do work before it finishes processing, everything is slow and choppy, and prone to crashes.  This was the final straw for me to make the jump to Lr.

I was very slow to warm to Lr, and worked with it for about 2 years before I decided to migrate my back catalog.  What I learned is that Lr is much more powerful and versatile, and has better integration with Ps.  This is to be expected, since Aperture has not been updated for so many years, and the technology has moved on without it.

I have 5 active libraries based on type of subject and type of file. This means that none are huge and I don't have any speed issues.
This is the advantage of a DAM and includes mirroring these libraries in separate vaults and other backup strategies. This year I will be starting another library to keep my UK library within not only file but project limits that I like to work to.
I am sure you are right as to new tech but some of that now is available in camera. Personally I never liked PS and only use it for a Canon print plugin these days.

Still here... anyone else on Aperture?

Still here... anyone else on Aperture? 

Yep. You are not alone. There really is no comparable database, despite plenty of editors.
A 256GB Aperture database of 106,000 photos and 4TB of referenced files using Mojave.
Everything star rated with Smart Albums.

Currently exploring Raw Power and hoping that it will eventually be able to do Lift and Stamp in the Photos app.

Me too, Bob. Raw Power looks great but the inability of Photos to do anything heavy duty on its own stymies my migration.

Star ratings, lift and mass stamp are the minimum that Photos needs to do and Apple still haven't added those features.

I've looked at most of the alternatives and they are lacking in one way or another in comparison to Aperture. I'm holding out hope that Affinity will come out with an effective Aperture alternative in 2021.
