[Qgis-user] QGIS 6.3 for macOS 10.14.5 : HELP

[Ramon Andinach]

Hi Nuno,

Glad it’s mostly working.

QGIS (and its tools) slowly gets better at noticing invalid layers, and there are a lot of changes between these two versions. I’d  run one of the geometry checkers over your layer, eg.  Vector -> Geometry Tools -> Check Validity, and see if that shows up anything.
If that doesn’t show anything I'm probably out, but maybe one of the others could help as this isn’t a Mac specific error.

Regards,
Ramon.
