Stuck on "Checking ICC repository…"

I had installed digikam over a year ago on a Mac, using a MariaDB database, but found it too buggy and crashy.

Being somewhat unhappy with other solutions out there, I thought I’d give it another try.

I downloaded and installed 6.3.0. When I try to run it, I get the splash screen and a few messages, then it hangs for at least an hour, displaying “Checking ICC repository…” in the upper left of the splash screen.

Any ideas on what I should try next? Is there a profile file somewhere I should delete to let it get a fresh start?

Thanks for any help offered!

which version of MacOS are you using? Catalina has proven very problematic for many FOSS applications.

High Sierra, 10.13.6.

I’m a coward. But I’m on ten-year-old hardware, and even running High Sierra required a patch kit.
