My Macbook air freezes when ejecting usb drive
Hi all,
Every time when I tried to eject usb drive from my macbook air, the whole system freezes. I can open and close applications but unable to shut down the computer. The only way is to hold the power key for a long time and force to shut down the system.
Can anyone figure out what's wrong?
Thank you very much!
