App compatibility

MacDupl doesn't keep a whitelist — it detects each app's underlying engine and applies the matching isolation strategy. That means broad families of apps work automatically, including ones not listed here.

The definitive answer for your Mac: download the free trial — the built-in scanner classifies every app in your Applications folder instantly.
