Open source version of the Macintosh Common Lisp development environment. Works on Intel and PPC computers with MacOSX 10.4 and up, including MacOSX 10.6 "Snow Leopard".

News

May 13, 2011: The MCLIDE Lisp IDE for Mac has an installer for MCL 6.

November 7, 2010: Preview of MCL 6.0 can be built from the sources.

Friday November 13, 2009: The rmcl52-1 zip distribution of RMCL 5.2.1 based on revision a498ea5438 fixes a number of issues reported for the previous RMCL 5.2 version.

October 9, 2009: The rmcl52.zip distribution of RMCL 5.2 for Intel and PPC replaces the previous rmcl52.dmg "rough build" announced on September 15. It differs from the previous in that the folder names and structure parallels MCL 5.2 (PPC only). The application itself also starts up without delay, as it is set to make a more reasonable initial memory allocation.

September 16, 2009: The source for the RMCL 5.2 branch is now open for development using Mercurial for revision control. See the Mercurial setup page for instructions.

An SVN archive with the original revision history is permanently available for future reference.
