From b314a4e8d68214549b1eeb2b608649cb7f26a57e Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 31 Jan 2026 15:33:09 +0000 Subject: [PATCH 2/9] feat: add full macOS Apple Silicon support with Bluetooth and USB This commit implements complete macOS support for phomemo-tools, including Bluetooth connectivity via IOBluetooth framework. ## Architecture Changes - Introduced platform abstraction layer for cross-platform support - Created modular bluetooth/ and usb/ packages with platform-specific implementations for Linux (BlueZ/D-Bus) and macOS (IOBluetooth/PyObjC) - Refactored phomemo.py backend to use the new abstraction layer ## New Files Backend modules: - cups/backend/platform.py - Platform detection utilities - cups/backend/bluetooth/{__init__,base,linux,darwin}.py - cups/backend/usb/{__init__,base,linux,darwin}.py Installation: - scripts/install-macos.sh - Automated macOS installer - requirements.txt, requirements-{macos,linux}.txt ## macOS Features - Full Bluetooth discovery via IOBluetoothDevice.pairedDevices() - RFCOMM connections via IOBluetoothRFCOMMChannel - USB device detection via PyUSB with /dev/cu.usbmodem* paths - CUPS integration using /usr/local/lib/cups/ (SIP-friendly) - Automatic platform detection and backend selection ## Compatibility - Maintains full backwards compatibility with Linux - Supports Apple Silicon (arm64) and Intel Macs - Requires macOS 11.0+ and Python 3.9+ https://claude.ai/code/session_01WBHE6TN5hyNn6pNDFTRMis --- cups/Makefile | 118 +++++++++-- cups/backend/bluetooth/__init__.py | 53 +++++

From 82a12778aaa87fb4911927536ab26b816b1af7da Mon Sep 17 00:00:00 2001 From: arnoutzw Date: Sun, 1 Feb 2026 01:05:35 +0100 Subject: [PATCH 4/9] feat(macos): add native C filter for CUPS printing macOS CUPS sandbox blocks Python filters due to xcode-select checks. This adds a native C filter that works around the restriction. Changes: - Add cups/filter/rastertopm110.c - native C CUPS filter for M110/M220 - Update Makefile to compile C filter on macOS - Fix bug in Python filters (stdout.write -> file.write) - Add macos/print-usb.py for direct USB printing - Add uncompressed PPD files The C filter links with libcups and libcupsimage, bypassing the Python sandbox issues on macOS.

This implements a helper daemon approach: - phomemo-bt-helper.py: Runs as user LaunchAgent with Bluetooth access - phomemo-bt-socket: CUPS backend that connects to helper via Unix socket - install-bt-helper.sh: Installation script for the helper daemon The helper daemon listens on /tmp/phomemo-bt.sock and forwards print data to Bluetooth printers using IOBluetooth/PyObjC. Also includes phomemo-bt.m as reference implementation showing direct IOBluetooth usage (works standalone, blocked by TCC under CUPS).

Switch to pure bash+nc approach for socket communication with the helper daemon. Changes: - Use netcat (nc) for Unix socket communication - Implement binary protocol header in bash (uint32_be function) - Handle SIGPIPE (exit 141) as success since data was sent - Remove Python discovery (can't run in sandbox) The helper daemon still uses Python with PyObjC for Bluetooth, but runs outside the CUPS sandbox as a user LaunchAgent.
