Bluetooth on 26.7.2. The report in
mt7925-hackintosh-wifi#4 says Bluetooth stopped
too. On Tahoe, bluetoothd needs LegionBtFix, and LegionBtFix's patches were made against 26.7.1 (25G241). If they no
longer match on 25G330, Bluetooth would come up and switch itself off after a few seconds, which also fits the open
report in MtkBt issue 1. We have not compared bluetoothd between the two builds yet, so this is Medium confidence.
thanhnndev/ga403wm-hackintosh#10: the HP OEM MT7925 (USB 0e8d:8c38) report is solved; the user says Wi-Fi and Bluetooth both work now.

flxxxxddd/SimpleMtkBtFw#2: BLE HID pairing stalls on Tahoe for MT7922 and RZ616.
The issue (23 Oct) says bluetoothd waits for the LE PHY Update
Complete and LE Data Length Change events, and the MediaTek controller never sends them. The reporter's workaround hooks
IOUSBHostIOSource::io to inject synthetic events behind a -smbtlefix boot-arg; it is in an open PR (#3). The repo is
GPL-3.0, so we read it as ideas only, and it lists MT7921, RZ608 and MT7922 only. A cheap check on our side: pair a BLE
HID device (mouse or keyboard) through MtkBt and LegionBtFix on the MT7925 and see whether it stalls the same way.
Medium confidence.
- macOS 26.7.2 may have taken the MediaTek Bluetooth USB device off the bus (a user with a B860 board sees it absent on 25G332). Apple's notes list USB, Bluetooth and kernel hardening (see mt7925-wifi-native); no public report explains it. LegionBtFix was patched against 25G241, so it needs a re-check on 25G332 as well.
