Sonoma Compatibility
If you recently updated to macOS Sonoma you likely had trouble with Nisus Writer. The most serious issue is related to Apple’s updated system-wide predictive text typing feature, which consistently triggers crashes in Nisus Writer.
There are a few other Sonoma issues that affect Nisus Writer, including problems using the print dialog. We have a pre-release beta version of Nisus Writer Pro that attempts to fix the most serious of these problems.
We’re very sorry for the trouble! We hope the beta helps while we smooth out other remaining issues.
UPDATE: The beta has been superseded by new app versions that officially support macOS Sonoma.
