Use the CanoScan OS 10.7 Driver for Mountain Lion
I downloaded the CanoScan driver for Mac OS 10.7 from Canon's web site, and it works with 10.8.4. I successfully Scanned with Photoshop CS6, Acrobat X Pro and Image Capture.
Go to:
http://www.usa.canon.com/cusa/support/consumer/scanners/canoscan_series/canoscan _lide70#DriversAndSoftware
- Select Operating System OS X v10.7 Lion
- Open Drivers
- Select LiDE 70 Scanner Driver Ver. 12.13.3
- You'll install and be forced to restart the Mac.
- Open Print & Scan in System Preferences.
- Click the "+" to add Printer or Scanner.
- Scroll down the list of devices and select "CanoScan LiDE 70"
- Click "Add"
You can scan right from the Print & Scan window:
Select "CanoScan LiDE 70" and click the "Open Scanner..." button
