Hmm... is something broken with the TWAIN scanner plugin on Mac, or perhaps have scanner drivers moved away from using the TWAIN system and so that's not picking up your driver?

(I ported the TWAIN driver to support Mac in 2004, and it seems to still be in the source code, so I would expect it to be included in builds by default.)

Hi,

Two years ago, someone in this list explained that there was no support for scanner in Gimp for Mac OSX,. I'd like to know if things changed in the latest developments.

I use Sierra, Gimp 2.10 and my scanner is a CanoScan 5600F. Should I move to another OS to use my scanner with Gimp or is there a way to make this work on OS X?

Thanks for any advise!

Ah, it was removed in 2016 in commit 8bb48ac5de915cf5b6f2136541c403101ddee52a:

"Bug 555525 - 64 Bit Build on Mac OS X Leopard fails...

...because of TWAIN interface

Remove all Mac TWAIN stuff, we will get proper OS X scanner support pretty soon."

The TWAIN driver had issues on macOS. I think that for macOS the right way forward is to implement a plugin that uses the ImageCapture libraries. This will give you imports from scanners as well as cameras (including iphones/ipads) for all devices that ship with appropriate macOS drivers.

I once started working on such a plugin but I have no interest in finishing it at this moment. It is not in a good enough shape to put in git. If anyone wants to continue working on this, let me know and I will happily share the code that I wrote as a starting point.

At one point, I was thinking the same thing! Also for Windows, use the native libraries.

Can you share your code offline with me? I'm not promising obviously since I'm not at all a good programmer.
