 ## Adding firewall entries for Jenkins workers

 Its necessary to accept the `known_hosts` keys interactively on first ssh or
 the release builds will fail. After setting up .ssh, do something like this:
+
 ```
 ssh node-www date
 // ... accept the host keys
 ```

+#### Full Xcode
+
+Xcode Command-line tools are not enough to perform a full notarization cycle, full Xcode must be installed manually.
+
+As root:
+
+* Download Xcode: https://developer.apple.com/download/more/ - find non-beta version, open Developer Tools in browser, Networking tab, start download (then cancel), in Networking tab "Copy as cURL" (available in Chrome & FF)
+* Download onto release machine using the copied curl command (may need `-o xcode.xip` appended to curl command) to `/tmp`
+* Extract: `xip --extract xcode.xip`
+* Move `Xcode.app` directory to `/Applications`
+* `xcode-select --switch /Applications/Xcode.app`
+* `xcode-select -r` - accept license
+
+#### Signing certificates
+
+* Extract from secrets/build/release: `dotgpg cat Apple\ Developer\ ID\ Node.js\ Foundation.p12.base64 | base64 -d > /tmp/Apple\ Developer\ ID\ Node.js\ Foundation.p12`
+* Transfer to release machine (scp to /tmp)
+* `sudo security import /tmp/Apple\ Developer\ ID\ Node.js\ Foundation.p12 -k /Library/Keychains/System.keychain -T /usr/bin/codesign -T /usr/bin/productsign -P 'XXXX'` (where XXXX is found in secrets/build/release/apple.md) (`security unlock-keychain -u /Library/Keychains/System.keychain` _may_ be required prior to running this command).
