It worked just fine with Snow Leopard and Win7, then when I updated to Lion the MacBook it seemed OK but wouldn't wake up without hanging (the Win 7 computer showed no issues).
I also disconnected Synergy to make sure that's what was causing the issue(s) and the MacBook worked like it should.
Anyone else have any luck with synergy km working with lion? The pref pane gives me all kinds of trouble.
Did you have any success? I get the same problems with the pref pane not responding etc.
