Disclaimer: I used to work for the company when they were HQ’d in Victoria.
I know the folks who work on the Mac version, and I always found the software pretty good … but it is not as advanced as Photoshop (nor priced like that) and more advanced than Photos … and there are other options in that middle ground, Iike Pixelmator Pro that are more “Apple-centric.”
That said, ACDSee for Mac is *great* for people who used it on that other platform, and worthy of taking a look at if you’re looking for an alternative photo-editing app.
