There seems to be a lot of confusion around this. Skype's official response? We no longer support anything lower than OS X 10.6. The issue was impacting users some users using OS X 10.7.5 Lion, as well as OS X 10.5 Leopard. Users on Skype's message board began complaining about being locked out of the service without warning this week.
For Mac owners still running OS X 10.5 Leopard or earlier versions of the Mac's operating system, there has been another casualty of time's passing - the ability to use Skype.
A sad reality of owning older Macs running old version of OS X is the steady ticking time bomb of obsolescence.
