macOS Sonoma Compatibility: QuarkXPress 2024 (v20.0), projected for November release, will be compatible with macOS Sonoma and all supported previous macOS versions. QuarkXPress 2023 will not be compatible with macOS Sonoma at the time of Sonoma’s release, so we recommend customers not to upgrade to Sonoma unless they have QuarkXPress 2024, as it may cause performance and stability issues.
