I am getting a repeated error:
Textastic quit unexpectedly.
I have been using the app as recently as a couple of hours ago...
I'm aware of a crash of the macOS version that happens to some users when restoring the application state on macOS 10.13.6. It does not seem to happen on 10.14 Mojave.
Please try the following to fix the problem:
If that doesn't help, you can also try to delete the folder "~/Library/Containers/com.textasticapp.textastic-mac" which will remove all preferences, saved application state, custom syntax definitions, themes and templates. It won't delete your documents.
I'm really sorry for the inconvenience. I'm still trying to figure out what exactly is causing the crash.
