Can using Little Snitch make my mac Less Secure than its “out of the box” settings?

Im thinking about configuring little snitch to allow all processes incoming and outgoing network traffic.

By allowing "any process” incoming / outgoing rights will this make my Mac less secure than its default settings (default out of the box, eg. not using OSX’s in built firewall tool)

The reason i want to do the above is because i want to block incoming and outgoing network traffic for a few applications. I can do this no problem with Little Snitch, but if i turn Little Snitch on it will by default block all network traffic and require each connection to be manually approved. To get around this i would setup the "allow any process" incoming and outgoing traffic rights.

This way all incoming / outgoing is allowed as a global rule, but certain apps are blocked as a specific rule.

Would doing the above make my Mac less secure than its default settings (default out of the box, eg. not using OSX’s in built firewall tool)

Welcome to Mac-Forums.

Short answer: no.

Long answer: Little Snitch isn't going to enable random settings that aren't enabled in the OS (screen sharing, file sharing, and things as such). So basically you are saying that it should all traffic that normally flows to continue to do so, except for a handful of select applications that will have their traffic restricted either incoming, outgoing or both. I played with Little Snitch a long time ago and realized the crazy amount of traffic that is going in and out from the various services/apps on my system and since there wasn't anything I was trying to specifically block, the resource hit wasn't worth it for me..

LOVE the answer options (short vs. long)!
