[digiKam-users] Database failure

[Ray Liggett]

I am trying to use the latest release of DigiKam (digiKam-6.4.0-MacOS-x86-64) on my Mac running Mohave. I have a large number of photos.
Initially tried the Mysql internal server but it crashed my computer. I deleted DigiKam finding all that I could then reinstalled DigiKam and used SQLite but still received a database fail message. 
I trolled through the archived subscriber entries for 3 months and found no solution but the suggestion to run a diagnostic which I’ve copied below.
What can I do now? Given I have > 200k photos should I be using MySQL?
Thanks
