[GNC] "No suitable backend was found" when trying to open file in 3.0

[Jeremy Doran]

Hello,

I just upgraded my version of GnuCash to 3.0 on my Mac, and now I am 
unable to open my account file - I get the error "No suitable backend 
was found for <filename>"

The filetype, according to the output of the 'file' command is: SQLite 
3.x database, last written using SQLite version 3007014

The same file opens without issue if I use 2.6.21.

Is SQLite no longer supported with Mac now?
