Mac OS X & Eclipse Mars (4.5.0)
The format of Mac OS X applications has changed in Eclipse Mars to make Eclipse and Eclipse-based applications look more like native OS X applications. This format change was done in a way that is not backwards compatible, however SDC can work around this issue and will not put your users into a broken state.
What does this mean for you? It means if you want to upgrade your existing package to Eclipse 4.5.0 on OS X, you have to run a two stage upgrade flow or run the package's installer. Because the old provisioning software doesn't know how to interpret the new format, a single stage upgrade will not be offered to users.
Your options for addressing this issue are as follows:
Use a New Package
Disable Mac OSX Support for the Package
In instances where your Mac installations are no longer receiving updates due to this installation change (Delayed Updates and Immediate Update options above), a notification will automatically be displayed in Mac OSX telling the user to run the installer. Please refer to this documentation for ways to customize this notification.
If you have any questions about these options, please cancel this promote and submit a support request. We are more than happy to help you with your upgrade process!
