mac系统的一些奇技淫巧

Mac从OS X以来发展也有十多年了，此间硬件变化很大，而系统默认设置出于各种原因比较保守，需要做些调整才能更好的发挥效力。

加快Samba文件传输速度

printf "[default]\nsigning_required=no\n" | sudo tee /etc/nsmb.conf >/dev/null

避免休眠写磁盘，加快唤醒速度

sudo pmset -a hibernatemode 0

优化Mail.app本地数据库

使用Brett Terpstra提供的Mail vacuuming script

使用noatime挂载文件系统

• 创建 /Library/LaunchDaemons/com.nullversion.noatime.plist ，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>com.nullvision.noatime</string>
          <key>ProgramArguments</key>
          <array>
              <string>mount</string>
              <string>-vuwo</string>
              <string>noatime</string>
              <string>/</string>
          </array>
          <key>RunAtLoad</key>
          <true/>
      </dict>
  </plist>
  

• 设置文件权限
  

  sudo chown root:wheel /Library/LaunchDaemons/com.nullversion.noatime.plist
  sudo chmod 644 /Library/LaunchDaemons/com.nullversion.noatime.plist
  

  ---

  那像我这样还另外还插了一张JetDrive闪存卡做扩展磁盘的话要怎么办呢？
  再加上一个plist文件 /Library/LaunchDaemons/com.nullversion.noatime-transcend.plist
  

  <?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>com.nullvision.noatime-transcend</string>
          <key>OrderPreference</key>
          <string>Last</string>
          <key>ProgramArguments</key>
          <array>
              <string>mount</string>
              <string>-vuwo</string>
              <string>noatime</string>
              <string>/Volumes/Transcend</string>
          </array>
          <key>RunAtLoad</key>
          <false/>
          <key>StartInterval</key>
          <integer>60</integer>
          <key>LaunchOnlyOnce</key>
          <true/>
          <key>KeepAlive</key>
          <false/>
      </dict>
  </plist>
