Photoshop CS6 Mac 64 Bit: Understanding TWAIN Drivers

If you're a Photoshop user, you may have encountered issues with your scanner not working in the latest version of Adobe's popular image editing software. This is often due to compatibility issues with the scanner's TWAIN driver. In this article, we'll explore what TWAIN drivers are, why they might not work in Photoshop CS6, and how to resolve any issues you may encounter.

What are TWAIN Drivers?

TWAIN (Technology Without An Intellectual Network) is a software interface standard that allows your computer to communicate with devices such as scanners, digital cameras, and printers. In the case of scanning, TWAIN drivers provide the necessary instructions for your scanner to capture an image and transfer it to your computer.

Compatibility Issues in Photoshop CS6

If you're running Photoshop CS5 in 64-bit mode on a Mac, you may still be able to use your TWAIN driver as usual. However, if you upgrade to Photoshop CS6, you may encounter compatibility issues with your scanner's TWAIN driver. This is because Adobe has switched to exclusive 64-bit operation in Photoshop CS6, which means that not all TWAIN drivers are compatible with the new version.

Intel vs PowerPC Processors

If your Mac is running Lion or higher and your scanner is working, it's likely that its TWAIN driver was written for Intel processors. In this case, the driver will work in Photoshop CS6. However, if your Mac is running Snow Leopard or earlier, you may need to contact your scanner manufacturer to see if they have an Intel-native driver available.

TWAIN Driver Limitations

Unfortunately, most TWAIN scanner drivers were written for 32-bit operation and are not compatible with the 64-bit operation of Photoshop CS6. This means that unless the developers of these drivers chose to re-write them for 64-bit operation, you won't be able to use them in the new version.

ImageKit: A New Alternative

In recent years, Apple has been encouraging developers to move away from TWAIN and instead use the ImageKit technology. ImageKit is at the heart of Apple's Image Capture utility, which allows users to easily scan and import images into their computer. Photoshop CS6 supports both TWAIN and ImageKit drivers, but it's likely that Adobe will be focusing more on ImageKit in future versions.

In conclusion, if you're experiencing issues with your scanner not working in Photoshop CS6, the issue may be due to compatibility problems with the TWAIN driver. By understanding how TWAIN drivers work and what limitations they have, you can take steps to resolve any issues you encounter. Additionally, it's worth noting that Adobe is moving away from TWAIN and towards ImageKit, which could potentially provide a more streamlined and efficient scanning experience in future versions of Photoshop.
