DOWNLOAD CoCoA-5 For Intel processors 64bit:
Emacs interface screenshots
  1. Download Emacs (we suggested Aquamacs)
  2. Download CoCoA-5 (save the CoCoA-5 folder where you want)
  3. Configure the Emacs-CoCoA5 communication in either way:
    • either quick and easy:
      1. In the CoCoA-5 folder, open the folder emacs
      2. Double-click on ConfigEmacs.command: it's really quick!!
        see below if you get a warning window (MacOSX 10.8 or later)
    • or for Emacs experts:
      the operation above adds a few lines at the end of your .emacs file (creating it if necessary). If you have already defined your own favourite Emacs options/colours/.. you might prefer to pick and copy from CoCoA-5/emacs/cocoa.emacs into your .emacs only the settings you desire.
Note: if you rename or move the CoCoA-5 folder you will need to repeat the configuration.
Some MacOS tricks
If you have MacOSX 10.8 (or later) you might get this error window:
"APPLICATION" can't be opened because
it is from an unidentified developer
Do this (as for any other application you download ... and you trust!)
  • Right-click (or Control-click) on the application icon and choose "Open"
  • Then click the "Open" button at the next warning (and it will not ask ever again!)
