iFamily currently has two versions in production. Their compatibility matrix ix:
Operating System
OSX 10.4 Tiger
OSX 10.5 Leopard
OSX 10.6 Snow Leopard
OSX 10.7 Lion
OSX 10.8 Mountain Lion
OSX 10.9 Mavericks
OSX 10.10 Yosemite
OSX 10.11 El Capitain
iFamily for Leopard
iFamily for Mac
Future version of OSX will be accommodated as they are announced.
If there are new features developed that work only on Later OSX's then we will let you know in the release notes. In the meantime iFamily for Mac will continue to be compatible with Older Versions of OSX for as long as possible.
iFamily has been built to take maximum advantage of whichever OSX you are running and all versions do run substantially faster on the Leopard operating system forward due to enhancements made by Apple when they released Leopard.
