After spending some time with OSX Yosemite we’ve determined that there are no compatibility issues with Smaart v7, Smaart v7 DI, or the Smaart I-O.
Although Smaart is compatible, we cannot guarantee that your audio device will work with the new OS. Check with your audio device manufacturer to ensure that compatible drivers are available before upgrading.
Do NOT deactivate Smaart before upgrading to Yosemite unless you are also fully reformatting the hard drive. Simply install the new OS and contact email@example.com if you encounter any problems.
