OS X El Capitan and Canon mg3600 I just purchased Canon MG3600 printer/scanner for use on OS X El Capitan. 

I am unable to get my Mac to open the install CD for the printer. "No application available". 

It will print and copy with scanner controls but not scan to computer. No computer control of scanner.  Any help? thanks
I NEVER use the drivers from the supplied media. I ALWAYS download the latest from the manufacturers website by googling (in your case) "Canon MG3600 Mac Driver."

Choose the top result that has "canon.com" as the domain (eg not an ad or a site specializing in driver downloads as they often bundle adware with the drivers) and you will (almost always) go right to the page where you can download the latest and greatest driver for your make and model of printer, scanner or any other 3rd party device that requires a driver.

It is possible that you got a Windows only CD or merely a defective disc. Regardless of that download the driver from the manufacturers site to ensure you have the latest and greatest version.
