- Add AppleSiliconSensors.swift for reading temperature via IOHID API - Use PMU tdie sensors for CPU/GPU temperature on Apple Silicon Macs - Skip SMC calls on arm64 to avoid assertion failures - Disable SwiftFormat build script for compatibility
- Display individual core usage with progress bars - Show P-core (blue) and E-core (green) labels on Apple Silicon - Add per-core temperature from PMU tdie sensors - Calculate real-time usage from CPU tick deltas - Add localization for cpu.cores
- Add resolvedDeviceId for Apple Silicon GPUs without device-id - Use IOAccelerator PerformanceStatistics for GPU usage - Fallback to AppleSiliconSensors for GPU temperature - Display GPU core count in menu view - Match Apple Silicon GPUs by prefix instead of PCI ID

看起来没什么大问题 But I don’t have deep expertise in the low level ARM API specifics, so it’s possible I missed something there...worth a second set of eyes from someone more familiar with that layer.

Adapts community PR gao-sun#273 onto the Xcode-26 base, with fixes: - New AppleSiliconSensors: reads M-series die temperatures via the private IOHIDEventSystemClient API (AppleVendor usage page, PMU tdie sensors) with dlsym resolution. Unlike gao-sun#273's version, the Copy-rule CF returns (event, Product string) are released per read instead of leaking two objects per sensor per tick, the owning CFArray is retained so cached service pointers cannot dangle, and sensor-name fallbacks (PMU tdie -> PMU2 tdie -> SOC MTR Temp Sensor) cover newer chip generations. - SmcControl: temperature getters fall back to IOHID when the SMC key is missing/zero, instead of gao-sun#273's exclusive #if arch(arm64) split - SMC stays open on Apple Silicon so fan readings keep working on machines that expose them. - CpuStore: per-core usage via host_processor_info with E/P-core labels (hw.perflevel1.physicalcpu; efficiency cluster enumerates first). gao-sun#273's per-core *temperature* display was dropped: it mapped alphabetically-sorted PMU sensors to core indices, which is arbitrary. - GPU on Apple Silicon: SystemProfiler gains resolvedDeviceId (AS GPUs have no PCI device ID), GPU.getInfo() no longer requires IOPCIMatch (AGXAccelerator), GpuStore matches the single shared-die GPU, and GPU core count is decoded. - CpuMenuBlockView: per-core usage bars in the CPU menu block ("cpu.cores" string added to en/zh-Hans). Verified on Apple Silicon (arm64 host, Xcode 26.3): Debug and Release both BUILD SUCCEEDED (Release universal x86_64+arm64); live run caches 64 IOHID sensor services; standalone harness reads 63 sensors with plausible values and cpuTemperature 48.0C. Known cosmetic follow-up: SMC lists two unreadable keys on AS whose failed reads log per tick before the IOHID fallback kicks in. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
