FAQs
Is Little Snitch a subscription?
No. The vendor sells it directly as a one time licence, and it is not sold through the Mac App Store.
Will it block my normal apps?
Only connections you deny are blocked. Most people allow trusted apps once and the alerts soon become rare.
What macOS versions does version 6 need?
Version 6 needs macOS 14 Sonoma or later. The vendor offers older versions for Macs on Ventura and earlier systems.
