Mac系统优化

适用Mac OS X 10.10及以上版本

1.修改打开文件数限制

sudo新建文件/Library/LaunchDaemons/limit.maxfiles.plist并添加以下内容：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
    <dict>
        <key>Label</key>
        <string>limit.maxfiles</string>
        <key>ProgramArguments</key>
        <array>
            <string>launchctl</string>
            <string>limit</string>
            <string>maxfiles</string>
            <string>1048576</string>
            <string>1048576</string>
        </array>
        <key>RunAtLoad</key>
        <true/>
        <key>ServiceIPC</key>
        <false/>
    </dict>
</plist>

2.修改打开进程数限制

sudo新建文件/Library/LaunchDaemons/limit.maxproc.plist并添加以下内容：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple/DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
    <dict>
        <key>Label</key>
        <string>limit.maxproc</string>
        <key>ProgramArguments</key>
        <array>
            <string>launchctl</string>
            <string>limit</string>
            <string>maxproc</string>
            <string>2048</string>
            <string>2048</string>
        </array>
        <key>RunAtLoad</key>
        <true/>
        <key>ServiceIPC</key>
        <false/>
    </dict>
</plist>

3.添加ls列出详细信息别名，修改grep高亮显示

sudo打开文件/etc/profile并添加以下内容：

alias ll='ls -l'
alias grep='grep --color=auto'

4.添加brew包管理程序并使用国内包镜像加速

终端直接运行命令以下：

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew install git
cd "$(brew --repo)"
git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git
brew update

5.添加Oh My Zsh并使用Zsh替换原有Bash

终端直接运行命令以下：

sh -c "$(curl -fsSL https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"
