I would like to run Omeka 2.4.1 with a MAC “El Capitan 10.11.6” on a local server using MAMP 4.0.4. It doesn’t work actually and I don’t found solution on the forum or online. Thank for everything fellows.
It’s been a while since I tried it, but my recollection is that OSX/MacOS and MAMP don’t include ImageMagick, which is the library that creates derivative images in Omeka. You might try the process described in this old forum post.
