I wanted to write a note of thanks. Syncmate has been a critical component of my software suite for over three years. It has allowed me to operate a multi-vendor configuration (Windows Desktop, MAC Laptop, Android Phone). Syncmate hasn't always been flawless, but it has been functional and for that I'm grateful.
The Mavericks incompatibility became a major stumbling block for me. I've adapted by moving to an iCloud based synchronization capability, and having made the move, I've deleted Syncmate from all of my platforms.
I was reluctant to move to a cloud-based solution for synchronization of my contact and calendar data, but thanks to the Mavericks/Syncmate incompatibility (and the lack of timely response from Eltima), I was forced to make the transition. I'm happy to report that the iCloud solution is "outstanding". It works well, provides for real-time synchronization, and is transparent to me (as the user).
Thanks Eltima, I appreciate all that you did for me.
