My one problem with Snow Leopard

Canon 4400F scanner not recognized

Here’s one for you Mac geeks out there.

I have a Mac Pro connected to a Canon 4400F USB scanner. The TWAIN driver plugin I use within Photoshop does not recognize the scanner under Snow Leopard. However, the driver works fine in Leopard.

I know that the scanner is being recognized by Snow Leopard, because it’s seen by the Image Capture application. The culprit points to the TWAIN driver plug-in. Anyone know where I can find a TWAIN driver Photoshop plug-in that works under Snow Leopard?

    The problem is the TWAIN driver is 32bit and Snow Leopard is 64bit. I’ve had problems with Disney web plugins not working in Safari under Snow Leopard as well. I was able to get it to almost work by telling Safari to start in 32bit mode. i.e. Get Info on Safari Icon reveals a new run as 32bit checkbox. But alas the plugin loads but due to OS identifiers being different the software refuses to run under Snow Leopard so I am stuck waiting on Disney to fix it. I don’t think there is much you can do until Photoshop and or the TWAIN driver vendor updates their software.

    I think that your can go into the File- Get Info for your scanner software and tell it to use 32 bit…
