Nisus Writer has issues with two recently released pieces of software:
1. The latest beta/preview version of macOS Monterey. Nisus Writer will often crash due to changes in the macOS system.
2. The recently released Bookends version 14. Nisus Writer can’t communicate directly with this version of Bookends due to internal changes in how the app identifies itself.
We are working on a software update to Nisus Writer that addresses all of these issues. We hope to finalize and release those updates soon. However, if you need to bypass these problems immediately please contact us about obtaining early access to a private beta version of Nisus Writer.
