I’d be thrilled to hear from ANYONE about their experience with TCBlock 2.8 on Lion because the only info available here so far are non-comment posts that it “works fine.” However, for some, this is a mission critical app that cannot be deployed on the basis of so little evident confidence.

So, my thanks to anyone and everyone who can supply even a bit more conviction.

I have TCPBlock installed on the last version of Lion and I can confirm that it works excellent, as it worked in Snow Leopard. So Alobar, don't worry.

TCPBlock works very well in lion. coming from littlesnitch it is allot more manual and there are much fewer options but it uses tiny CPU and does everything it says it will capably.
