+
+1. Save the following text as `entitlements.plist`
+
+```xml
+<?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>
+```
+
+2. `codesign --deep --force --verify --verbose --options runtime --timestamp --entitlements entitlements.plist --sign 'XXXXXXXXXX' monero-wallet-gui.app`

 Note that the installer build process is now reproducible / deterministic. For details check the file [Deterministic.md](Deterministic.md).
 
 The build steps in detail:
 
 1. Install *Inno Setup*. You can get it from [here](http://www.jrsoftware.org/isdl.php)
-2. Get the Inno Setup script plus related files by cloning the whole [monero-gui GitHub repository](https://github.com/monero-project/monero-gui); you will only need the files in the installer directory `installers\windows` however. Depending on development state, additionally instead of simply using `master` you may have to checkout a specific branch, like `release-v0.15`.
-3. The setup script is written to take the GUI wallet files from a subdirectory named `bin`; so create `installers\windows\bin`, get the zip file of the GUI wallet from [here](https://getmonero.org/downloads/), unpack it somewhere, and copy all the files and subdirectories in the single subdirectory there (currently named `monero-gui-0.15.0.0`) to this `bin` subdirectory
+2. Get the Inno Setup script plus related files by cloning the whole [monero-gui GitHub repository](https://github.com/monero-project/monero-gui); you will only need the files in the installer directory `installers\windows` however. Depending on development state, additionally instead of simply using `master` you may have to checkout a specific branch, like `release-v0.16`.

 4. Start Inno Setup, load `Monero.iss` and compile it
 5. The result i.e. the finished installer will be the file `mysetup.exe` in the `installers\windows\Output` subdirectory
