The device is relative to its functionality well. You have to handle with care, because the import-rails are very fragile. But Mac users need to know that there are no drivers for the latest operating system Mavericks. The device does not work on this OS definitely. The problem is that this is clearly evident on the US site of Canon. On the German site, the Mac compatibility is to certify general. That Mavericks is excluded from this, you can not refer to the German Canon website. The support of the company Canon is abysmal organized. No one feels responsible. It will be referred to e-mail addresses that do not respond and phone numbers, where nobody stands out and comes after about 10x ringing to note that you should check the phone number. The simple fact that Canon did not make it to today, provide a driver for Mavericks, no support staff was known. I myself found out by studying the US site. I tested the scanner then under Mountain Lion: He works there properly. The action took me two weeks research. That's annoying.
