Comment (by ha):

 Are the entitlement files Tor plans to use available online somewhere to
 look at.

 If you're using the Firefox production entitlements as a starting point,
 you might be able to change some rules to be more restrictive.

 Assuming Tor only loads shared libraries signed by Tor or Apple, you
 should be able to set the disable library validation entitlement[1] to
 false. Firefox needs to load libraries signed by Adobe and Google for
 Flash and Widevine video decoding respectively.

   com.apple.security.cs.disable-library-validation=false

 In Firefox, we had to recently set this[2] to true because some
 WebExtensions using the native message API relied on helper applications
 that use Apple Events. I suspect Tor wouldn't need this and could set the
 entitlement to false.

   com.apple.security.automation.apple-events=false
