How can I get the old version of little snitch that I can use the serial number I first purchased??
I'm using a new version of MAC (Mojave) and IU tried to install my license but out said that my system, its not compatible and I need to use a new version of Little Snitch. How can I use a preview version with my serial number?
BTW- if I want to buy a new version (updated) how much it will cost?
