问题描述
在 M1 Mac Mini 上，
如果我执行 uname -i，我会得到：
uname: illegal option -- -
usage: uname [-amnprsv]
如果我执行 uname -m，我会得到：
x86_64
如果我执行 uname -a，我会得到：
Darwin bevrymemacmini.local 20.5.0 Darwin Kernel Version 20.5.0: Sat May 8 05:10:31 PDT 2021; root:xnu-7195.121.3~9/RELEASE_ARM64_T8101 x86_64
只有在 uname -a 中，我才能通过 ARM64 部件获得它在 Apple Silicon 上运行的信息。
是否有更好的方法来确定我在 Mac 机器上运行的架构？
解决方法
使用这个命令
“sysctl -a | grep machdep.cpu” 获取有关 CPU 的详细转储。
命令 “sysctl -n machdep.cpu.brand_string” 将只返回英特尔型号和速度。
使用英特尔从我的 mac 输出
