mac问题汇总
记录macos初次使用的一些问题
显卡切换
sudo pmset -a GPUSwitch i
i = 0/1/2 cpu/gpu/auto
外接显示器必须得开独显，贼坑
强制退出程序
cmd + opt + esc
三指拖动
偏好设置 -> 辅助功能 -> 指针控制 -> 触控板选项
homebrew
mkdir homebrew && curl -L https://github.com/Homebrew/brew/tarball/master | tar xz --strip 1 -C homebrew环境变量
默认的sehll是zsh, 需要将~/.bashrc,~/.bash_profile,/etc/profile中的变量移到zshrc中， 或是在zshrc中source下bash中的变量
同程序不同窗口切换
cmd + ~
同窗口不同标签
cmd + opt + </>
Quicktime录屏，仅录制内部声音
安装soundflower插件，再到音频MIDI设置中添加聚集与多输出设备
vscode代码补全tab切换
command + shift + p, Preference: Open keyboard Shortcuts(Json)

WireShark权限
sudo chown wcw bp*Xcode c IO输出
左侧navigator的Products， 右键项目， Show in finder
vscode 上下次位置
win10 alt + <-/->
mac ctl + shift + - / ctl + -
Xcode malloc incorrect checksum
cmd + 8切换断点导航栏， 左下角➕选择Symbol断点， 然后在Symbol字段下添加malloc_error_break, module会默认匹配到libsystem_malloc.dylib ， 添加action, bt(backtrace), 即可像python那样打印异常栈，
其实也可以直接在报错的调试栏进行的交互式lldb来手动打印bt， 定位代码段， 打印变量， 地址
Product下的Scheme可以设定各种malloc的守护机制， 帮助定位malloc错误
Xcode lib location
Xcode默认的IDE lib是不包括openssl的， 而mac又是自带openssl的， 只需要将openssl的include软连接到Xcode的include下，
应用->平台->SDK，臭长臭长的/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/
which、where的话，只能看可执行文件的位置， 万能的google还是能找到， lib通常会在/usr/local, binary则是/usr/bin ，
sudo ln -s /usr/local/opt/openssl/include/openssl .
然后就能正常#include <openssl/ssl.h>
