Getting CanoScan to work on MacBook Pro

Getting CanoScan to work on MacBook Pro

Please refer to the Solution Summary section (below) for a more concise instruction on how to get your previously worked-in-Windows Canon scanner running on your Mac OS computer. I placed some reference points within [square brackets] in the Process section that refer to the Summary and vice versa.

The situation:
A couple months ago, I switched from using Windows OS to Mac OS X. Just last week, I needed to scan a menu to add to my web portfolio with my Canon scanner--CanoScan LiDE 80.

The problem:
It worked beautifully as a plug-and-play on Windows, but my Mac laptop didnt detect the scanner when plugged into its USB port.

The solution-led process:
[1, 2, 3] Since I couldnt find the original installation CD, I turned to Canons download library for my scanner model:

I just needed to download and install the OS X driver without the scanner plugged in. Okay, but it asks where to install the file. I had no idea, so I turned to Google and came across Dylan Mullins blog post, "CanoScan LiDE 50 Twain Issues Resolved":

[4] He describes how he got his scanner to work with Photoshop CS4. So that got me wanting to get my scanner to work with my Photoshop CS3. But first, Dylan came across another post that gave me possible installation locations:

I tried installing the driver in Photoshops folder that contains the TWAIN.plugin file (Applications > Adobe Photoshop CS3 > Plug-Ins > Import/Export). Rebooted and opened up Photoshop, only to get an error message. (Note: I dont remember the exact message, but it something about not being able to find or access the plug-in.) And didnt see an option to access my scanner under File > Import.

Not wanting to face defeat any more, I went back to Canons site, downloaded and installed the CanoScan Toolbox, and rebooted. The scanner still didnt work. Remembering that the scanners driver was still in the Photoshop folder, I moved it (ScanGear CS 7.2X) into the scanner-appropriate folder (CanoScan Toolbox 4.1 > Plug-Ins). And wella! The scanner came to life, I scanned the menu using the Toolbox, and the new image showed up on the desktop.

[6] I didnt get the scanner to work with Photoshop after following Sewjes suggestion (post #17) to link Photoshop to view the scans. I tried to "set" Photoshop (Applications > Adobe Photoshop CS3 > Adobe Photoshop CS3.app > Contents > Mac OS > Adobe Photoshop CS3 (Unix Executable File)) as the "Link scanned image to" location. No go.

[5] Today, I went back to the Mac Rumors post, came across MikeMaravilhas post (#18) and did the following:

• Before going on, make sure Photoshop is closed.
• In Finder, look for "Adobe Photoshop CS3.app"
• "Get Info" for the file (right-click on the file / look under File > Get Info / Command-I)
• Click on "Open using Rosetta" to select it (See top image)
  
• If its not there already, put a copy of "ScanGear CS 7.2X" in Applications > Adobe Photoshop CS3 > Plug-Ins > Import/Export folder to keep the TWAIN.plugin file company
• Open Photoshop and look under File > Import and there it is--ScanGear CS! (See bottom image)
