omnis-pkg

This is a template for building .pkg installers for Omnis Studio-based projects on macOS.

Prerequisites

Compatibility

This example is build against Omnis Studio 8.0.2 but should work with any recent version of Omnis Studio.

Customizing the template

Prepare a copy of your application in a folder other than /Applications. The installer will be built from this copy.

Download or clone a copy of this repository. For example, this command will clone a copy of the project to a omnis-pkg folder in ~/Documents.

git clone https://github.com/barkingfoodog/omnis-pkg.git ~/Documents/omnis-pkg

Rename the Omnis.pkgproj file to match your application. Open this file with Packages and edit these settings:

  1. Project -> Settings -> Name
  2. Project -> Presentation -> Title -> Distribution Title
  3. Packages -> Right-click Omnis -> Rename -> Enter your application name
  4. Packages -> [Your Package] -> Settings -> Tag -> Identifier -> Enter com.[your company].pkg.[your application]

Replace the placeholder Omnis Studio Runtime with your application.

  1. Go to Packages -> [Your Package] -> Payload -> Contents -> Applications
  2. Right-click Omnis Studio Runtime 8.0.2 x64.app and Choose Delete...
  3. Confirm the delete
  4. Right-click Applications and choose Add Files...
  5. Select your source application

You can store the absolute path to your application or make it relative to the Packages files or its containing folder.

Change the permissions on the app to:

Read Write Exec
Owner X X X
Group X X
Others X X

Leave the Bit unset for all.

Edit the postinstall script and set APP_NAME and COMPANY_NAME for your application. This will allow the script to set permissions and update the user's application data properly.

Optional customizations

preinstall script

You can edit the preinstall script to ensure your app is shutdown or make any other pre-requisite checks.

postinstall script

You can extend this script to make changes to the system after your app is installed. This script will be invoked with root privileges via sudo.

License

Edit the license.rtf to add your own license agreement that will be displayed during installation.

Excluded files

In Packages, edit the Project -> Settings -> Exclusions list to exclude any files in your source application from the installer. For example, if you manage your installer in Subversion or git, exclude the .svn or .git folders.

Installer steps

You can add an introduction, read me, or other steps to the install process under Project -> Presentation. Review the Packages resources and linked sites for more information.

System Requirements

You can set minimum system requirements for running the installer under Project -> Requirements & Resouces. Double-click a requirement to edit it, and use the + and - buttons to add and remove additional requirements. This template is set to require:

  • 2 GB RAM
  • 1 64-bit Intel core
  • macOS 10.9 and later

Building a package

GUI

Open your .pkgproj file with Packages. Go to Build -> Build.

CLI

/usr/local/bin/packagesbuild -v "[path to your .pkgproj]"

Code signing

Install your Developer ID private key and certificate on the build machine. Code signing takes an un-signed package file and creates a signed package file. If your package is omnis.pkg, rename it to omnis_temp.pkg.

# If you're automating this process, run this command to unlock the keychain so the Developer ID certificate can be accessed
security unlock-keychain -p "[your macOS user password]"

# Sign your temporary package with your Developer ID Installer certificate
productsign --sign "Developer ID Installer: [Your company name]" "[Your package]_temp.pkg" "[Your package].pkg"

# Verify the signature
spctl -a -v --type install "[Your packages].pkg"

A recent addition to Apple's security flow is the concept of notarizing your software. You can notarize your installer using the xcrun command line tool by following this guide.
