1) `<= a major version` is highly unusual and likely to lead to errors in the very near future. Does this need a FIXME + radar about reenabling it for future point updates?
2) what about the iOS-derived platforms that use this sandbox file but do not use __IPHONE_OS_VERSION_MIN_REQUIRED?

I have uploaded a new patch which I think should resolve these issues.

Thanks for reviewing!

The new version check is odd for a different but very similar reason :) Maybe you meant < 160000?

Also, you definitely still need a FIXME.

Also, is it really OK that you're disabling this security feature for watchOS and tvOS?
