I did have a few issues with DarkTable last year when I acquired a Lumix TZ100, but that appears to have been resolved. Of late much of my photography is headed for the blog, and I find Snapseed a better means of finishing that resolution of photo. I'm still doing the 9 to 5 as an IT Manager / Head of IT, though the family have grown up, but I am very pressured time-wise. As you say, anything that speeds up workflow... .
Totally agree about the Mac. A few traumas in the last few years have left a budget choice of do a bit of travel, or invest in hardware. Travel won! It is a work in progress though.
I'm very interested in some of your articles on the Indie-web. I do need to do some research I think.
