Important Applications and Support Information


Flash from Adobe:
While not a part of the install, Flash is still fully supported and can be downloaded from Adobe.

Java's Runtime Environment:
Java is a universal programming language that allows software and utilities to be compatible across a wide variety of devices. OS X El Capitan will present a prompt to download Java if an application needs Java to function correctly.

Rosetta:
Rosetta is a program that allowed PowerPC apps to run on an Intel based Mac, and was last supported in OS X Snow Leopard v10.6. Apps that require Rosetta to run will not work in OS X El Capitan. If you run older software or believe a software program you use relies on Rosetta you can check with the software developer before upgrading to see if you'll experience an issue, or if an upgrade is available.

General Application Support:
RoaringApps has the broadest coverage of application compatibility with various Mac OS X versions: http://new.roaringapps.com
