For those who use Skype, they will be disappointed when it stops working. I have some good free Skype for Mac alternatives that can be even better than Skype in some situations.
The main Mac client application that I suggest is Gizmo Project with you can download here. Gizmo is a free phone for your computer but is open source – so isn’t controlled by one company.
I often have use for this free skype for Mac alternative. Try Gizmo today!
