I had a little trouble setting this up between my MBP OS10.6 and iMac OS10.9 and the instructions didn't help much, but finally figured it out.

Everything is running very smoothly and I have full remote control of the MBP via mouse and keyboard, while at the same time I still have full control of the MBP with its own mouse and keyboard.

Now that it is working, I am *very* impressed.

'Thank you' to the devs – you can expect to see a donation from me real soon.

Excellent program, took a little firewall tweaking to get it running, server on Mac, client on Win7 32bit.
Works smoothly as described, however can't get the file copying between machines to work yet. But for a open source program to control two machines with one lot of hardware, brilliant.

Instead of bickering over who copied whom, do something useful and tell us how well this app works, or doesn't. What kind of latency is involved, for instance, using a wired/wireless network connection? How do you switch between computers? Do you need a client version of the app on each computer and, if so, how does it handle different versions for older iterations of OS X? Stuff we actually need to know that's not revealed in the sparse app description.

Version of the app on the about page is 1.4.15 (not 0.9.0 as listed here).

There's an issue with v1.4.15 under Mavericks that needs a workaround which is listed here - http://superuser.com/questions/656912/synergy-on-mavericks-osx-10-9-and-enable-assistive-devices

Seems it will be fixed in the next release? (1.4.16?)

Incredible that theDeveloper didn't do the necessary research to not copy the name that Wincent has on his application.

This predates Wincent's synergy


Yes, this is a very old and mature project that I was using many years ago on my linux configurations, at least 2005 or earlier.


You can date the original Synergy project back to 2004...I've dig out the original config file created in Oct. 2004 in my home directory of my new MacBook Pro Retina, while I was using my good ol' Powerbook G4 to remotely control a Windows XP machine on a shared ViewSonic 19" monitor.

I've stopped using Synergy several years ago, but the original configure file was passed from machine to machine via Migration Tool and Time Machine all these years.

Not to be confused with the iTunes controller of the same name, that's been around for years and years?


Doesn't anyone do research anymore?

Evidently not:



You'll find this synergy predates Wincet's synergy by a number of months, and this synergy is also based on another project called Synergy which dates back to the mid-1990's



Yes, the iTunes controller is the copycat in this case. Synergy has been around since before 2005.


Sorry, yes, natenate19 is right. I was trying to recall from memory when I first used it and was thinking it was around 1999 or 2000, but I could only find mailing lists that dated back to 2005 apparently when some effort shifted over to sourceforge. Glad to see the wikipedia page, thanks @natenate19.


Which one is older on the Mac? That's what counts. That there was an app used on Windows and Linux before coming to the Mac *after* Wincent came out with his Synergy, an entirely different app, is what counts. Unless, of course, people truly believe that Wincent deliberately copied the name of a non-Mac app to apply to his Mac app, the way that Steve copied Apple from the Apple Corp. and copied Macintosh from McIntosh Stereo, of course. You never know.
