上传rz 下载sz
- 首先下载 iTerm2 因为自带的 terminal 不行啊
- 安装 lrzsz brew install lrzsz , 安装完成后,m1的brew安装位置是在 /opt/homebrew/ ,需要 copy 到

cd /opt/homebrew/bin
cp sz /usr/local/bin/ cp rz /usr/local/bin/ - 下载两个脚本 send-zmodem.sh recv-zmodem.sh如果链接失败,可以复制以下文件

brew
https://brew.sh/ Mac 上面最好用的软件管理工具。
mac上使用brew install /brew cask install安装软件总是先updating HomeBrew…
HomeBrew 关闭自动更新, 减少等待的时间1
2
3vim ~/.zshrc
export HOMEBREW_NO_AUTO_UPDATE=true
更稳妥的办法是固定版本1
2
3
4brew pin python@3.9
brew list --pinned
python@3.9
固定好之后,python 就不会被自动更新了。之前遇到过 brew 自动更新了 python 从 3.7 到 3.9 导致了 pycharm 创建的虚拟环境都不能用了。
.zshrc
mac 常用的小脚本, 顺便安利一下大佬的 bash 教程1

2K 显示器 HiDPI
- intel 可以尝试这个方法 https://blog.csdn.net/qq_37417018/article/details/113701115
- M1 芯片可以用这个方法 https://sspai.com/post/70141 普通版就可以,不需要 Pro 的高级功能。但 2022-06-19 今天它更新了,不需要 dummy 投影来修改分辨率了。
而且还支持键盘控制多个屏幕的亮度,修改默认分辨率等高级功能, 真心建议 15 美元买 Pro 版本。 这篇文章也有介绍 https://zzbloc.top/archives/turn-on-hidpi-for-macbook
关于显示器亮度: 软件上默认最大亮度是你的显示器按键设置的当前值,比如我的显示器按键设置当前值为60%,用 BetterDisplay 控制亮度时,最大值就是60%,我可调整的区间为0-60%,而不能增加到60%以上
