Hello!

Can't install, here is the output from console:
sed: resources/settings.model: No such file or directory
chmod: caesaria.macos: No such file or directory

Do you have any ideas?

Thanks in advance!

Having the same issue, is there a solution out there?
Tried the Gist (i am a total noob though) and am having the same problem just this time its line 28
sed: resources/settings.model: No such file or directory

Please help!
