One impressive feature I’ve tested is dictation and the way it seamlessly runs alongside keyboard input. Also iCloud Photos can easily be shared by creating an iCloud link that can then be pasted into an email or message. For the Enterprise administrators out there it’s all about the device management improvements. Features such as enforced software update, Automated Device Enrollment and the support of Managed Device Attestation to name just three.
Apple have already seeded a public beta of macOS Sonoma 14.1 to developers. My advice is wait until that update is tried and tested, or risk issues and niggles with the functioning of your applications.
