I don’t get the Samsung Xpress M267X/287X scanner to work with 10.8. The scanner shows up in Image Capture but it need additional software, which it can’t find.
Does someone has a link to the right drivers?
You should be able to download this from Samsung's support center. There were new scan drivers released 9th of April this year and they can be found here: http://www.samsung.com/us/support/owners/product/SL-M2875FD/XAA
Remember to follow the instructions supported by Samsung:
Security setting should be changed in order to install drivers in Mac OS X 10.8:
Run [System Preferences] under [Application] folder
Select [Security & Privacy]
Select [Anywhere] under [Allow applications downloaded from]
