Within the folder kobopatch_4.38.23171 should be a folder named bin, and in that should be the file kobopatch-darwin-64bit. Do you see that?

I also run on a Mac, and I find the instructions to patch confusing, so after much trial and error I have made my own instructions. Some of the instructions are specific as to how my Mac works; for instance, when a zip file is opened, the original zip file is moved to the recycle bin. Also, I keep a copy of settings files for my Kobo things in a folder in my Documents folder.

1. Download the official firmware. The zip should be called something like kobo-update-1.2.3456.zip.
2. Unzip the official firmware and copy it to .kobo
3. Eject and unplug the Kobo and allow the firmware to install, then replug the Kobo.
4. Download the Kobopatch zip for your firmware version. Unzip.
5. Move the original zipped firmware from the recycle bin to the src folder of Kobopatch.
6. Edit the kobopatch.yaml file in Documents to reference the firmware number.
7. Copy the kobopatch.yaml file from Documents to the Kobopatch main folder.
8. Open Terminal and drag kobopatch.sh to the Terminal to run it.
9. If the patching succeeded, a file named KoboRoot.tgz will be created in the out folder. Copy it to the .kobo folder of your device. Eject and unplug the Kobo and allow the firmware to install.
