How to Find The Entitlements a macOS App

Sandboxed apps have their entitlements embedded into the signing data. To see what any app's entitlements are, type the following in Terminal:

codesign -d --entitlements - /Applications/Some.app/

This will print out a plist. For example:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
 <key>com.apple.security.app-sandbox</key>
 <true/>
 <key>com.apple.security.network.client</key>
 <true/>
</dict>
</plist>
