Install from DeepL's official Mac page
Begin on DeepL's official macOS app page and verify the current operating-system requirements. On managed Macs, installation or accessibility permissions may be controlled by an administrator.
Review each requested permission in context. Shortcut-driven translation may need different access than simple browser translation.
Run a controlled first test
Translate a short selection, then a small document that contains representative headings and terminology. Check both translation quality and formatting before scaling the workflow.
If a shortcut conflicts with another application, change the assignment instead of disabling unrelated macOS security settings.
