Programatically fetch macOS Version using golang

问题

我想在golang中获取macOS版本。
基本上想检查macOS是否大于或等于Big Sur。

找到了goInfo包。但它没有提供所需的详细信息。
尝试了syscall包,但该解决方案只适用于Linux。

任何帮助都将不胜感激。

Found goInfo package. But it doesn't provide the required details.
Tried syscall package but the solution works only on Linux.

any help is appreciated.

使用unix.Uname函数来获取darwin的发布版本。根据darwin的发布历史,Big Sur对应的darwin版本是20.x.x

以下是示例代码:

package main

import (
	"fmt"
	"strconv"
	"strings"

	"golang.org/x/sys/unix"
)

func main() {
	var uts unix.Utsname
	if err := unix.Uname(&uts); err != nil {
		panic(err)
	}

	sysname := unix.ByteSliceToString(uts.Sysname[:])
	release := unix.ByteSliceToString(uts.Release[:])

	fmt.Printf("sysname: %s\nrelease: %s\n", sysname, release)

	if sysname == "Darwin" {
		dotPos := strings.Index(release, ".")
		if dotPos == -1 {
			fmt.Printf("invalid release value: %s\n", release)
			return
		}

		major := release[:dotPos]
		majorVersion, err := strconv.Atoi(major)
		if err != nil {
			fmt.Printf("invalid release value: %s, %v\n", release, err)
			return
		}
		fmt.Println("macOS >= Big Sur:", majorVersion >= 20)
	}
}

在我的计算机上的输出结果为:

sysname: Darwin
release: 22.3.0
macOS >= Big Sur: true

英文:

Use unix.Uname to get the release version of darwin. According to the release history of darwin, the corresponding darwin version of Big Sur is 20.x.x.

See the demo below:

package main

import (
	"fmt"
	"strconv"
	"strings"

	"golang.org/x/sys/unix"
)

func main() {
	var uts unix.Utsname
	if err := unix.Uname(&uts); err != nil {
		panic(err)
	}

	sysname := unix.ByteSliceToString(uts.Sysname[:])
	release := unix.ByteSliceToString(uts.Release[:])

	fmt.Printf("sysname: %s\nrelease: %s\n", sysname, release)

	if sysname == "Darwin" {
		dotPos := strings.Index(release, ".")
		if dotPos == -1 {
			fmt.Printf("invalid release value: %s\n", release)
			return
		}

		major := release[:dotPos]
		majorVersion, err := strconv.Atoi(major)
		if err != nil {
			fmt.Printf("invalid release value: %s, %v\n", release, err)
			return
		}
		fmt.Println("macOS >= Big Sur:", majorVersion >= 20)
	}
}

Output on my computer:

sysname: Darwin
release: 22.3.0
macOS >= Big Sur: true
