For several weeks I was frustrated that LogMeIn didn't work on my iMac i5 running 10.6.2. I couldn't find any explanation. I made do with the almost inert Java applet or used my MacBook (10.5) to maintain my mother's Mini.
Turns out LogMeIn is not fully compatible with Snow Leopard. It only works if Safari runs in 32 bit mode.
It did work for me in 32 bit mode, but it was flaky. I switched to Firefox which is still 32 bit (the 64 bit version is in beta I think). It worked there.
Obviously LogMeIn.com isn't exactly dying to please OS X customers. This should have shown up in blazing red letters for every OS X user who logs in to the service. Practically speaking, LogMeIn is not compatible with any of Apple's newer machines.
I don't mind them not having a fix, I do mind the time I wasted trying to make their product work.
Anyone know a better (please, no VNC) remote control solution? I don't mind paying! (Yes, I know about Apple's remote control solution. It's almost as crummy as iChat.)
