I installed program called "MIT/GNU Scheme" to /Applications. I can run it via Spotlight, but it says it's from unidentified developer. So I should find it in the folder and right click open, but it's not in the folder. Terminal autocomplete cannot find it either. If I install it again, it says it is there and asks whether to replace the old file. Read somewhere it might be 32bit version on my 64bit system, but I specifically installed 64bit version. I am running OS X 10.10.4

    Where did you get it from?

  • Is there anything beginning MIT in your /Applications folder - The documentation is appalling for OS X and should be reported as a major bug. This question on SO suggesting macports or homebrew which is usually the best way for a command line Unix program where the developers don't seem to know OS X

  • How did you install it? When I download the dmg and drag and drop the application to the /Application folder, I can see it in Finder, ls /Applications lists it, and I can run it from command line with /Applications/MIT\:GNU\ Scheme.app/Contents/Resources/mit-scheme.

You can confirm where it was installed in /Applications by using Terminal.app:

cd /Applications
ls -lt | grep -i cheme

This should print the name of the directory where it was installed (which should be MIT:GNU Scheme). You can access it from the command-line by adding the following directory to your PATH: /Applications/MIT\:GNU\ Scheme.app/Contents/Resources.

  • thank you, my problem somehow went away, not sure if it was because of your advice, but I can see the app now, so I'm closing the question

Alternatively, you can also visit the Security & Privacy panel in System Preferences right after trying to run the program from Spotlight. The panel should have an option to run (the last tried) program from an unidentified developer.

  • Yes that allows me to run the file, thank you. I'm still unable to run it from console, delete and link it, though. (Sorry if I wasn't clear in the original question)

  • @rdkn - you do not mention anything about console in your question - you need to edit that. Also you can't run anything from OSX's console which is a viewer of log files. Perhaps you mean Terminal?
