Any idea how to find out which App/process is doing this? (the router only shows the source IP address)
Note: I have a license to Little Snitch, which would probably show me, but this is a corporate MBP and I don’t dare to install LS on it because of all the “resident” crap that IT already installed (I’m afraid my Mac won’t even boot anymore if I do).
In ‘Silent Mode’ Little Snitch is preconfigured to let all traffic through and let you view what’s come in via its Network Monitor, and you can decide later what to block, if anything.
A free alternative to view network connections is Netiquette, but if you already have LS it’s more powerful and has a better UI
