Apple Watch Unlock - Intermittently Unavailable

Hello @saronian! 👋

Thank you for reporting the issue! The behaviour that you described sounds similar to an issue that our developers discovered in macOS and filed a bug report with Apple for. Does Apple Watch unlock generally stop working after you wake your Mac from sleep? If you leave the Mac alone, and awake, for a while (such as for half an hour) does the ability to unlock using your Apple Watch eventually return by itself?

I look forward to hearing from you.🙂

Yes - It consistently stops working after the display "sleeps" and Apple Watch also tries to unlock the Mac but fails.
Display is set to turn off on power adapter after 3-hours. Anytime prior to that Apple Watch continues to work.
Once the Apple Watch stops working it will not return without a restart.
Also no screen saver is set and I do require the computer password immediately after screen is off.

Thank you for the reply. That does sound similar to the issue that our developers reported to Apple. I would also encourage you to report the issue to Apple from your end as well so that they're aware that it's affecting you and to see if Apple can offer any workarounds or suggestions in your case: Official Apple Support

Let me know if you have any questions. 🙂
