Comments about LuLu by Objective-See as a Alternative to Little Snitch
Almost everyone thinks LuLu by Objective-See is a great Little Snitch alternative.
I've used Little Snitch for many years. However, after buying a new Mac I was faced with buying licences for a whole bunch of apps I had paid for several times in the past. Given this unwanted additional expense and the fact that I really don't need all the extra features of the later versions of Little Snitch, I decided to try alternatives. LuLu absolutely fits the bill for the purpose of stopping apps phoning home without your permission.
