LUISMURBINA  I have used it for a couple of months now. Synchro SVN works just fine. I had to manually create a repository in my machine, but once that was done and I connected to it there were no issues. It works as intended.

The other (well known) multi-platform option is Smart SVN but after downloading a demo I couldn't get it to connect to my local repository.

The interface does not look particularly mac-like but that is probably because this is a multi-platform solution. I need to develop on Windows and on the Mac and wanted to use a SVN gui that works on both platforms. If this is not what you are looking for and/or you want a more mac-like look-and-feel, you might want to look at versions or cornerstone (the best of the two in my opinion) instead.

With regards to one of the previous reviews I have been able to connect to an https server without a problem, using user and password login details as appropriate.

M!K3  Well, I've tried to do some basic things like updating my working copy or getting it to connect to our https-repository. But no success - I just did not found a way to tell Syncro about the location of my credentials.

COOLFACTOR  Sure looks like they put a lot of work into "re-inventing" the Mac interface. What's with two close buttons per "window"?

Windows thinking and interface approaches doesn't work on this side of the fence.

SULEIMAN  lol...it's clearly a MAC screenshot.
