Lightroom CC won't update

Have searched the support pages and have tried all the suggestions including completely removing CC- restart and reinstalling as in:

Available updates not listed for Adobe Creative Cloud applications

"Preview unavailable for this File"

Everything else seems to be latest version.

My camera Panasonic Lumix GX85 raw files will not open i LR but opens fine in Adobe Bridge.

Im running LR on a Mac Mini using Sierra

Any ideas ?

Thanks in advance
