Click Ok in the dialog.\r\n2. Find the package in Finder.\r\n3. Control Click (click while holding the `ctrt` key) on the package icon.\r\n4. Click open on the context menu that comes up.\r\n![image](https://user-images.githubusercontent.com/10873629/67424786-a6404580-f58b-11e9-9a5d-8ce796259d94.png)\r\n\r\n## Workaround - Command Line\r\n\r\n1. run `sudo xattr -rd com.apple.quarantine \u003cpath to package\u003e`, replace `\u003cpath to package\u003e` with the actual path to the `.pkg` file.\r\n2. Then install the package as you normally would.\r\n\r\n## Required changes\r\n```\r\n1.       Opt-in to use runtime hardening when developing your app.\r\na.       Insert the following key by editing your info.plist: CSFlags of type int, 65536 is the hardening value\r\n                \u003ckey\u003eCSFlags\u003e\r\n                \u003cinteger\u003e65536\u003c/integer\u003e\r\n                                       i.            Create entitlements file\r\n                                     ii.            Pass a directive to codesign with entitlements file\r\nSame entitlements file and syntax are used for both hardening and sandboxing but they are orthogonal to each other.\r\n```","author":{"url":"https://github.com/TravisEz13","@type":"Person","name":"TravisEz13"},"datePublished":"2019-10-23T18:54:11.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":26},"url":"https://github.com/10874/PowerShell/issues/10874"}
