Hello everyone,  
Can’t launch the last available FMOD Studio 2.1 on my OS X 10.1.6.  
Instantely gives me this error:

Updating OS is not an option - my old MacBoock Pro 2009 supports El Capitan only.  
2.00.08 works fine.

FMOD Studio version 2.01.00 for Macintosh requires macOS version 10.12 or later. It will not run on earlier macOS versions.

if you are unable to upgrade your machine to a new macOS version, we recommend continuing to use FMOD Studio version 2.00.xx, or upgrading your hardware so that you can run a compatible operating system.

It looks like our downloads page incorrectly says that FMOD Studio version 2.01.00 will run on macOS 10.9. We will update the page to show the correct minimum version. Thank you for bringing this issue to our attention.
