2021 update with minor bugfixes.
- In OSX, launch TykeTypeDev from the
tyketype_appfolder. - Don't separate the app from the
datafolder that contains the font it needs, or it won't launch. - If MacOS complains that TykeType "is damaged and can’t be opened", then in your Terminal,
cd tyketype_appand thenxattr -cr TykeTypeDev.app/, which removes extended file attributes. - press command-q to quit.
- you may need to change your settings to “Use F1, F2, etc. keys as standard function keys”.
