Mac System Requirements

Igor Pro® 9 runs on macOS 10.13 - 10.14. Igor Pro 9 for Mac is only available as a 64-bit application.

Igor Pro 9 does run on macOS 10.15 (Catalina) and later (though not officially supported), but see this discussion of caveats and known issues.

Since Igor Pro 9  is compiled for the Intel processor, Rosetta 2 is required for ARM-based Macintoshes.

Windows System Requirements

Igor Pro 9 runs on Windows 7 or later. Both 32- and 64-bit applications are installed by default.

Igor Pro and Linux

At the present time Igor does not run under Linux.

Some users have had some success running Igor via Wine and via CodeWeavers' CrossOver Office Wine-based product. You can read about their experiences by searching the Igor mailing list database for "Linux" or you can view a summary in the Are you porting Igor to Linux? article in the forum.
