I've installed the latest version of LibFredo v8.0, am running Sketchup 2017 on Mac OS High Sierra. Every tie I restart Sketchup, I get the message 'You must intstall LibFredo6 version 6.9 or higher to run Fredo6_RoundCorner. But I have version 8 installed. When I go to my Extension Manager, it shows that LibFredo ver8.0b - 19 Nov 17 is installed and enabled. Why do I keep getting this error message?

I think you also need to get fresh version of RoundCorner (and other plugins).

On High Sierra, there is an incompatibility introduced by Apple (order of file loading). So the fixes are in LibFredo6 7.9 and higher, but as well in each plugin.
