Running Snow Leopard. Since I upgraded to Parallels 5, every time I log in, I get prompted: I click Allow. I check the Firewall pane of Security preferences, where I see under advanced: How can I get this to apply "yes, now and forevermore, don't ask me every time I log in to my computer?"
Experiencing the same thing I think it might be related to the Parallels iPhone app. I downloaded that and played with it once or twice. I don't really use it anymore, and I'd bet that disabling support for the app in the Parallels preferences might make that message go away.
Thanks - I knew it was the control software for the iPhone linkage. However, I use the iPhone linkage, so removing it isn't an option. I just want to approve it via the firewall without needing to reapprove it every time I log in to the computer.
