0.4.1

FPPBox 0.4.1

Touch the sensor on a sleeping Mac and it wakes up, unlocks, and you are at your
desktop. One touch, no keyboard.

The firmware and the app must be updated together. The device and the app
changed what they say to each other, so a 0.4.1 app with older firmware (or the
reverse) will not work together.

Wake a sleeping Mac

Until now the reader only worked while the Mac was awake: if the screen had
locked or the Mac had gone to sleep, a touch did nothing.

Now the reader wakes the Mac by itself, so the whole thing is one touch:

1. The Mac is asleep and the screen is dark.
2. You touch the sensor with an enrolled finger.
3. The reader matches your finger and wakes the Mac.
4. The lock screen appears. The app types your password, and you are in.

One thing worth knowing: the reader scans for a finger while the Mac sleeps, so
it can wake it. Older builds stopped scanning unless the Mac had asked for an
authentication, which is why a touch while asleep used to do nothing.

Your password still never leaves the Mac

Nothing changed about the guarantee in 0.4.0. The reader sends a short signed
note that says "a finger matched", the app checks it, and the Mac types the
password itself. The password is not sent to the reader, not written to it, and
not stored there.

Fixes

• Deleting fingerprints no longer fails with "error code 6". The reader
  refuses commands while an authentication is armed, and the app used to leave
  one armed whenever a macOS password prompt had focus. Deleting a fingerprint
  while a prompt was open was rejected. It now cancels that request first.
• The password is typed much faster. The delay between characters went from
  15 ms to 1 ms, so typing a password takes about 30 ms instead of about half a
  second.
• The Mac App asks for Keychain access once instead of three times. The
  pairing key, the password, and the host key used to be three separate Keychain
  items, and macOS asks for permission per item. They are now one item, so macOS
  asks once. Your existing items are moved into the new one automatically on
  first launch.

Installing

File	For
FPPBox_0.4.1_universal.dmg	Intel and Apple Silicon (recommended)
FPPBox_0.4.1_aarch64.dmg	Apple Silicon
FPPBox_0.4.1_x64.dmg	Intel

The app is not notarized, so macOS blocks the first launch: right-click the app
and choose Open, then confirm. After installing, make sure FPPBox has
Accessibility permission in System Settings → Privacy & Security → Accessibility.

Updating from 0.4.0

Flash the new firmware first, then replace the app. Your saved password, the
pairing key, and your enrolled fingerprints all stay as they are. Nothing needs
to be re-enrolled or re-paired, and the app asks for Keychain access once while
it moves the old items into the single new one.
