What changed for LDB on Sequoia vs. Sonoma
- 30-day Screen Recording re-confirmation (15.3+). The biggest change. LDB shows the Screen Recording consent dialog every 30 days instead of once. Apple's privacy enhancement; not an LDB bug. See dedicated page.
- TCC database stricter (15.0+). System Settings shows the toggle on but LDB can still receive denial in some edge cases. Reset procedure: reset permissions.
- Apple Intelligence integration (15.1+). Cosmetic only - no LDB impact.
- Audio HAL changes (15.2+). Minor - Bluetooth profile switch is fractionally slower; impacts AirPods system check timing.
The Logitech BRIO 4K quirk on Sequoia 15.4
Symptom: Logitech BRIO 4K webcam not detected by LDB on macOS Sequoia 15.4 specifically, despite working in FaceTime.
Cause: Sequoia 15.4 changed the AVFoundation property exposure for cameras with multiple sensor modes. Logitech's BRIO 4K driver requires a one-time initialization from Logi Tune (Logitech's utility) before TCC reflects the camera correctly.
Fix:
- Download Logi Tune from logitech.com.
- Launch Logi Tune at least once. Confirm it sees your BRIO 4K.
- Quit Logi Tune.
- Launch LDB. Camera detection works correctly.
Recommendations for Sequoia users
- Update to Sequoia 15.4 if you're on 15.3.0 or 15.3.1 - 15.4 fixed several TCC re-confirmation bugs.
- Run LDB at least 24 hours before each exam to handle the 30-day re-prompt outside the exam window.
- If you have a BRIO 4K: install Logi Tune.
- Update LDB to 2.1.5.01: 2.1.4 still works but 2.1.5.01 has minor improvements specific to Sequoia.
Frequently asked questions
Will my exam fail because of the 30-day Screen Recording re-prompt?
Only if you don't click Allow when the prompt appears. The prompt itself is one click; the failure mode is users who don't notice the prompt and assume LDB is hanging.
Should I upgrade to Sequoia 15.4 from 15.3?
Yes. 15.4 fixed several TCC bugs from 15.3, including some that cause LDB-specific issues.
Does LDB use Apple Intelligence features?
No. LDB explicitly does not invoke Apple Intelligence. The two systems coexist on the same Mac without interaction.
