A new update for IDL on Macintosh computers is now available. The IDL 7.0.4 release adds support for Macintosh Intel 64-bit architecture on OS X 10.5. IDL 7.0.4 also fixes two issues that impacted all supported Macintosh platforms: CR49844 - "Creation of Semaphores Fails under Mac OS X 10.5", and CR51198/CR51412 - "CURSOR/RDPIX Procedures not Working Correctly on OS X".

Note: Some IDL Macintosh users who are current on software maintenance may encounter a license error when trying to run the IDL 7.0.4 update. If you encounter this issue, please contact ITT VIS Technical Support at techsupport@ittvis.com. They will issue a new license file that works properly with IDL 7.0.4.
