Cocoa App Update: App needs to download an update, close the app, install the update, and relaunch the updated app

Question

I have built a Mac OS X app using Xamarin. I also have a XML file that dictates which users should get updates,when should the users get the updates and a few more logic. Ideally my app looks at the XML file, and if the user satisfies all the conditions mentioned in the XML, I want to provide an update to the User.

Currently, I am able to download the dmg to the users machine, but I can't have it installed automatically.

However, after downloading I want to do the following automatically: 1. Close the app 2. Install the update 3. Relaunch the updated app

Until now, I read about sparkle - but however I do not think sparkle could support the XML file that I am using to drive the logic of who receives updates.

Do any of you have suggestions on how to achieve this?

Answer 1

You could still use Sparkle. Sparkle offers a variety of hooks that allow you to use Sparkle's infrastructure without being tied to their UI or their relatively basic business logic. You should look at their documentation in more detail.
