I have an Apple Mac Book, I Use this at my office as well as home for Personal Use. I have some Secure and personal Data stored in my Mac. Sometime I use this Mac for presentation and demo for my staff and I want to be sure that no one can copy Data from my Mac. So I want to  Prevent Users from Accessing USB Storage Media like USB HDD, USB Flash Memory, USB Card Reader and USB Mobile Phone Data Cable. But At the Same time I want to Access to access my USB Storage on this Mac. Is it Possible to block USB Pen Drive in Mac PC?

Hi,
As per my knowledge I am not fully sure but I think this will work for you .Either you can disable it fully or keep it. But there are no settings to accept only Apple devices such as iPad / Mac book and deny access to the rest. In case if you want to disable USB storage, open the terminal and type the following commands :
Code:
cp /System/Library/Extensions/IOUSBMassStorageClass.kext ~/backup/Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â
sudo srm -rf /System/Library/Extensions/IOUSBMassStorageClass.kext
sudo touch /System/Library/Extensions
sudo reboot
Repeat these instructions every time a system update is installed. Tested on OS X v10.6.Â

Thanks
How to block USB Pen Drive in Mac.
Hi Rutil!!
I have analyzed your important question. Now I am giving you the appropriate commands by entering which you can block your usb drives. You can disable it permanently or block for a few moments.
You have to open the terminal. Then you should  write down each word by separating with slash.
cp system Library Extensions IOUSBMassStorageClass.kext~backup sudo srm -rf System Library Extensions IOUSBMassStorageClass.kext sudo touch System Library Extensions sudo reboot.
I hope this will help you.
Thanks
