If denying the request to accept incoming network connections does not seem to hinder an app, how would one go about finding out why the app asked to allow incoming network connections in the first place.

For example, On Hightail Express I select deny when prompted, and it seems to work as normal (it's not that great though!). When asked Hightail say it's important to the running of the app, but I see zero difference.

  • I'm not sure I understand your question. You're allowing connections thru the Mac's firewall to the application. What the application is doing, only the developers know for sure. Have you tried Little Snitch to see exactly what connections are being made? – fsb Jan 8 at 17:43

  • Thanks for the edit. Only the developers would know what they do with the network connection. You need to ask them. Alternately, you can use Little Snitch to see where the connections are being made (outside of your network) to guess as to their use by the application. – fsb Jan 9 at 18:19
  • So Little Snitch would help me find out what those incoming requests are and/or where they go and what they do? I can buy it. Is it simple to understand? I'd put myself as middling, but can read a manual, when it comes to computers. – cheakypawl Jan 10 at 19:04
  • Take a look at their site. I have the software. It tells you what application is requesting network access, where that call is going or coming from, and they have an online db to look-up commonly used calls. It has a free trial for 1 week. – fsb Jan 10 at 20:39
