iCloud Photos “Optimize Mac Storage” deadlocks frequently correlate with bird (CloudDocs daemon) quota exhaustion on the Data volume, exacerbated by Bluetooth bluetoothd crashes leaking file descriptors into the com.apple.photos.VideoConversionService sandbox. Run brctl log -w --shorten to catch QUOTA_EXCEEDED errors, then purge local optimization caches via sudo rm -rf ~/Library/Photos/.photoslibrary/resources/derivatives/ and reset the CloudKit container with brctl account remove iCloud; brctl account add iCloud. For concurrent Bluetooth drops, check log show --predicate 'subsystem == "com.apple.bluetooth"' --last 30m | grep -E 'HCI|LMP|timeout' and reset the Bluetooth module NVRAM via sudo nvram bluetoothHostControllerSwitchBehavior=always; sudo pkill bluetoothd to force a clean LMP re-negotiation.

The thicker tempered glass increases the dielectric gap between your fingers and the Pencil Pro’s squeeze electrodes (located under the matte cap), attenuating the ~100–300 kHz near-field coupling the sensor relies on. Hover works because it uses the iPad’s display-side mutual-capacitance grid (stronger field, larger RX/TX area), whereas squeeze is a self-capacitance measurement on the accessory itself—far more sensitive to added series capacitance. CLI check: Pair Pencil → xcrun developerctl device log --predicate 'subsystem == "com.apple.pencil"' while squeezing; look for SqueezeGestureRecognizer confidence scores dropping below 0.6. Recovery: Remove protector → test baseline → if restored, the glass exceeds the ~0.35 mm effective thickness budget for reliable squeeze detection; switch to a ≤0.3 mm PET/film protector or use the “Squeeze Sensitivity: Firm” setting (Settings → Apple Pencil → Squeeze) to raise the detection threshold.

– Force-quit the Photos app (swipe up from the bottom, pause, then swipe the Photos card away), then reopen it to restart the sync session.
– If that doesn’t resume syncing, go to Settings > [your name] > iCloud > Photos, turn off “Sync this iPhone,” wait ten seconds, then turn it back on — this forces a fresh indexing pass without signing out of your Apple Account.
