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

1
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

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>

    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
