    I have the new MBP 13" 2.4ghz, and I installed 'Little Snitch' last night. Once I started running it my MBP was running extremely slow, close to the point of locking up. I was not running many other programs, just mail, iCal, and Safari. Has anyone else had this problem? I like the idea behind 'Little Snitch' I just don't want my computer dragging along like a snail.

    I ended up uninstalling it. Rebooted several times and it didn't help. There weren't even that many programs talking to the web, but it was running slower than my wife's iBook G4 sitting next to it.

    I don't think it was LS...I've used it for a couple years now and never had a problem with it.

    You uninstalled the program and then rebooted, and it's still lagging? That suggests it's not Little Snitch.

    I've disabled little snitch myself but not because it was slowing down my Mac but I was tired of its notifications, about various apps.

    There is no more lag now that I uninstalled, my MBP is back to its normal self. I will check the link to make sure I installed the right LS, but I'm pretty sure it was the right program.

    Make a rule that allows all connections for all applications, that fixes it. All your other rules will still apply so don't worry :cool:

    I must not understand LS....how would all your other rules apply if you had a rule that allowed all connections for all apps? Wouldn't that rule take precendence or does it process that rule last or something?

    Nah, it doesn't, that's how I have it set up and I've got zero notifications. It allows connection for apps that don't have any other rule disallowing it. I don't know how they do it and care even less, I just care that it works :cool:

    I think you meant deny access for all applications not on the list. Allowing everything else would make the firewall essentially useless.

    Never seen Little Snitch cause any performance issues. More than anything I wish there was something equal for Windows 7.

    No, it does not. I've set allow connection to any app but I also have deny for e.g. CS5, see the pic, works flawlessly

    I have, but there always seems to be a wrinkle in that another program wants access or this or that.

    I know over time, as I use it, the rules will be honed to the point where I'm comfortable. In the end, I just didn't want to wait that long, and given my modest needs, I opted not to use it. I only use a handful of apps, so the risks are rather low for me.

    Do you have to set every app manually? Where does it place files and how many?

    As far as I know, yes, but you can create rules like deny/allow access for all apps

    Well, you should change it to deny anything but the applications allowed. While this means you have to manually add applications to the list, it also means that no unauthorized apps will have net access. Now everything is allowed except those you've specifically denied. Personally I feel that the Little Snitch dialogs are not a bother, you can simply check for example any connection and then allow or deny it forever. After a while you rarely see the dialogs.
