Processor identifier

The information describe the processor identity and its reported capabilities

Original source

The macOS processor identification is provided by MacOsProcessorIdentifier, which inherits ProcessorIdentifier

val processorInfo = hardware.processorInfo
val processorIdentifier: ProcessorIdentifier = processorInfo.processorIdentifier

See central processor for the containing API

The CPU vendor reported by macOS

val cpuVendor: String = processorIdentifier.cpuVendor

println(cpuVendor) // e.g. Apple Inc.

The commercial name of the processor

val cpuName: String = processorIdentifier.cpuName

println(cpuName) // e.g. Apple M1

The numeric CPU family value represented as a string

val cpuFamily: String = processorIdentifier.cpuFamily

println(cpuFamily) // e.g. 458787763

The commercial chip name on Apple Silicon, or the numeric CPU model represented as a string on Intel

val cpuModel: String = processorIdentifier.cpuModel

println(cpuModel) // e.g. Apple M1

The processor stepping value. Apple Silicon uses unknown

val cpuStepping: String = processorIdentifier.cpuStepping

println(cpuStepping) // unknown

The identifier assembled from architecture-specific CPU values. It is not a unique hardware serial number

val processorId: String = processorIdentifier.processorId

println(processorId) // e.g. 0100000c1b588bb3

The descriptive identifier assembled from the processor name and family, with model and stepping information when available

val cpuIdentifier: String = processorIdentifier.cpuIdentifier

println(cpuIdentifier) // e.g. Apple M1 Family 458787763

Whether the native query reports 64-bit CPU capability. A failed query returns false

val isCpu64bit: Boolean = processorIdentifier.isCpu64bit

println(isCpu64bit) // e.g. true

The reported nominal processor frequency in hertz, or 0 when unavailable. On Apple Silicon it is derived from the performance-core frequency table

val cpuVendorFreq: Long = processorIdentifier.cpuVendorFreq

println(cpuVendorFreq) // e.g. 3204000000
