  • mac 鼠标指针慢

    接了外接的 usb 鼠标后，会出现拖动无力的情况

    重置NVRAM 或 PRAM 之后，鼠标非常顺畅

    OPTION+Command+P+R+POWER

    Option-Command-P-R: Reset NVRAM or PRAM. If your Mac is using a firmware password, it ignores this key combination or starts up from macOS Recovery.

    打开 System Report => 图像显示, 发现
    UI Looks like: 2560 x 1440 @ 29.00Hz
    想办法证它显示 4k 60Hz
    下载 SwitchResX4.zip，选 2560x1440x60Hz 在 DELL U2720QM Display 效果最好
