使用 golang 以编程方式获取 macOS 版本

php editor Banana teaches you how to use golang programming to get the macOS version. Whether you are developing macOS applications or performing system administration, it is important to know your current operating system version. Using golang programming, we can easily obtain the version information of macOS. This article will introduce how to use golang to write code to get the macOS version, and how to run the code on the terminal to view the results. Let’s explore this fun and practical topic together!

Question content

I want to get the macOS version in golang. Mainly wanted to check if macOS is >= Big Sur.

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

Thanks for any help.

Solution

Use unix.uname to obtain the darwin distribution. According to the release history of darwin, the corresponding darwin version of big sur is 20.x.x.

See 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

Learn Go String Manipulation: Working with the 'strings' PackageMay 09, 2025 am 12:07 AM

Go's "strings" package provides rich features to make string operation efficient and simple. 1) Use strings.Contains() to check substrings. 2) strings.Split() can be used to parse data, but it should be used with caution to avoid performance problems. 3) strings.Join() is suitable for formatting strings, but for small datasets, looping = is more efficient. 4) For large strings, it is more efficient to build strings using strings.Builder.

Go: String Manipulation with the Standard 'strings' PackageMay 09, 2025 am 12:07 AM

Go uses the "strings" package for string operations. 1) Use strings.Join function to splice strings. 2) Use the strings.Contains function to find substrings. 3) Use the strings.Replace function to replace strings. These functions are efficient and easy to use and are suitable for various string processing tasks.

Go bytes package: short reference and tipsMay 08, 2025 am 12:05 AM

Go's bytes package is mainly used to efficiently process byte slices. 1) Using bytes.Buffer can efficiently perform string splicing to avoid unnecessary memory allocation. 2) The bytes.Equal function is used to quickly compare byte slices. 3) The bytes.Index, bytes.Split and bytes.ReplaceAll functions can be used to search and manipulate byte slices, but performance issues need to be paid attention to.

Go bytes package: practical examples for byte slice manipulationMay 08, 2025 am 12:01 AM

The byte package provides a variety of functions to efficiently process byte slices. 1) Use bytes.Contains to check the byte sequence. 2) Use bytes.Split to split byte slices. 3) Replace the byte sequence bytes.Replace. 4) Use bytes.Join to connect multiple byte slices. 5) Use bytes.Buffer to build data. 6) Combined bytes.Map for error processing and data verification.
