Mohamed,
I'm able to start the MIT-GNU Scheme on a Mac from Emacs and use it by adding this to my .emacs file:
(add-to-list 'exec-path "/Applications/MIT:GNU Scheme.app/Contents/Resources")
(eval-after-load 'scheme
'(setq scheme-program-name "mit-scheme"))
I don't get far launching from Finder, because of a startup error:
$ open /Applications/MIT\:GNU\ Scheme.app/Contents/MacOS/macosx-starter
/Applications/MIT:GNU Scheme.app/Contents/Resources/mit-scheme: can't find a readable default for option --band.
searched for file
all.com in these directories:
/Applications/MIT:GNU Scheme.app/Contents/Resources?
/usr/local/lib/mit-scheme-x86-64
Inconsistency detected.
I'm using Sierra 10.12.3
Happy SICP'ing!
