The only fixed requirement is that you already have the Viber app preinstalled on your mobile device, whether it be Android or iOS, so you can sync your account details and view all the data assigned to your phone number, including contacts and chat history. This is a new software that’s compatible with the various available mobile versions of Viber and offers you a complete and fully functional alternative to let you communicate with your contacts, sending and receiving calls and messages no matter which device you’re on. Viber for Mac is a solid IM and VoIP client that's worth trying for anyone that's had enough of Skype and Messages.Viber, the popular IM and VoIP app for mobile devices, also has its own desktop client for Windows and Mac, which massively increases the flexibility of this widely used, free communication tool. However, some users have already reported problems with syncing and the lack of ability to call mobiles is a bit disappointing.

Viber for Mac generally syncs very reliably and efficiently and the quality of video-to-video on Mac is as good as anything Skype can offer. You'll need to sign-up for a Viber account if you don't have one, which you are prompted to do when you setup the app. Anyone who has used Skype or Messages will have no problems using Viber. The interface is very elegant and easy to use. You can make calls and video chats with other Macs but you can't yet make video calls to mobile devices or do video conferencing using Viber for Mac. Contacts are also synced, although some users already report some problems with this.

Viber does a good job of making sure that wherever you left off on your mobile device, your chats can be picked up. The developer of Viber for Mac is keen to highlight that it has superior mobile syncing than competitor products.
