[NTG-context] ConTeXt Minimals on Mac

I have installed the Context Minimals following the newbie instructions on the wiki at contextgarden for Mac users. The instructions themselves are clear but should perhaps be updated: • the file originally downloaded is first-setup.sh not first-setup.tsh • to execute this file run ./first-setup.sh not first-setup.sh (at least, the former worked and did not return a “command not found” message). I also configured TeXShop as instructed. But now when I try to typeset a file, I get the error message: Users/alancbowen/Library/TeXShop/Engines/ConTeXtMinimals.engine does not have the executable bit set. How can I fix this? Alan Note: I am running Mac OS X 10.5.4.
