Hello Samuel,
* The R2025a Mac bundle is only compatible with the Apple silicon chipsets. Additional development time would be needed to make a universal macOS binary (Intel & Silicon compatible) application and we unfortunately did not have the resources/time to do that for R2025a. * Since the R2025a Mac bundle is not a universal macOS binary, Mac Intel users would need to compile the code with adjustments to the cmake and some files to make a bundle compatible with the Intel chipset. GMAT compile instructions are located in the following wiki: https://gmat.atlassian.net/wiki/pages/viewpage.action?pageId=380273355 * There a Mac specific instructions that have to be added to that wiki, but at a high level it has the information needed to compile GMAT. Comments can be added to the wiki for the adjustments needed for the Mac. * The following ticket has been created to capture the work to make the Mac build universal but the current projected completion date is TBD: https://gmat.atlassian.net/browse/GMT-8340 * In the event a customer requests this functionality we will update the ticket.

Importance: High CAUTION: This email originated from outside of NASA. Please take care when clicking links or opening attachments. Use the "Report Message" button to report suspicious messages to the NASA SOC. The Read-me file for version R2025a of GMAT says that it is incompatible with Mac OSX Sequoia (15.4.1) using the Intel chipset, but was built for and compatible with the Apple M2 chip-set. * Is this correct, or is it really a "fat" application meaning that R2025a of GMAT can run under both chip-sets? * If so what is the correct installation procedure to void getting an incorrect installation error message? I * If R2025a is not a "fat" application, will there be a release of GMAT that is compatible with Mac OSX Sequoia using the Intel chipset, and if so when will it be released? Please advise. Samuel Dupree.
