Have tried installing geotiff and tiff libraries with macports and homebrew without success.
On Linux installing libgeotiff got the plugin working.

@nohal ... Any ideas on this please.

You have built it on ARM against the TIFF libraries from Homebrew, the result is on x86_64 the linkage is missing completely (Homebrew is single architecture), so the plugin can't work at all on older Intel Macs and on Apple Silicon you need the dependencies from Homebrew installed (brew install libgeotiff will pull everything in) for the plugin to work.

With the Homebrew deps installed and available it does load on an Apple Silicon machine:

Thanks for confirming. I will leave the issue open in case anyone has the same problem.
