Mac OS X Installation

Epsilon for Mac OS X supports drag and drop installation. Simply open the disk image in the "macos" folder on the CD-ROM and drag the Epsilon application inside to your Applications folder. Epsilon supports Mac OS X version 10.4 and later on Intel-based Macs. A legacy package in the "powerpc" folder supports old PowerPC-based Macs running OS X 10.3.9 through 10.6.8.

Epsilon includes a setup script, and there are some advantages to running it, though it's optional. The setup script will install Epsilon and its EEL compiler on your path, so you can run them from the command line more conveniently. And it will link Epsilon's Info documentation into the main Info tree, so other Info-reading programs can locate it. To run Epsilon's setup script from a shell prompt, type

sudo "/Applications/Epsilon.app/Contents/esetup"

assuming /Applications is where you installed Epsilon.

Epsilon for Mac OS X can run as an X11 program or as a curses-based console program. Normally it automatically chooses the best way: as an X11 program if there's a DISPLAY environment variable or if X11 is installed, otherwise as a console program. OS X versions through 10.7 (Lion) come with X11 preinstalled (or available on your installation disk as an optional extra), but starting in 10.8 (Mountain Lion), the XQuartz program must be installed from http://xquartz.macosforge.org/ for X11 support. This is highly recommended, since Epsilon for OS X works best as an X11 program.

Any time Epsilon documentation mentions the "Unix version" of Epsilon, this also includes the Mac OS X version. In particular, Epsilon for Mac OS X recognizes all the X11 flags described in the previous section, and all the X11 resource names documented there.
