Fixed: 在Lion上執行Parallel出現"Unable to Load the Parallels Driver"

開啟 Terminal ，切換為 root 身分：

sudo su

以root權限執行以下指令：

sudo kextutil "/Library/Parallels/Parallels Service.app/Contents/Kexts/10.6/prl_hypervisor.kext"
sudo kextutil "/Library/Parallels/Parallels Service.app/Contents/Kexts/10.6/prl_hid_hook.kext"
sudo kextutil "/Library/Parallels/Parallels Service.app/Contents/Kexts/10.6/prl_usb_connect.kext"
sudo kextutil "/Library/Parallels/Parallels Service.app/Contents/Kexts/10.6/prl_netbridge.kext"
sudo kextutil "/Library/Parallels/Parallels Service.app/Contents/Kexts/10.6/prl_vnic.kext"
