bliss and OS X Mountain Lion

Mountain Lion

Just five days ago, July 25th 2012, Apple released their latest iteration of the OS X operating system: OS X v10.8 commonly known as "Mountain Lion".

Just one day later I got the first report that bliss was not working with Mountain Lion. Sure enough, further emails arrived in the mailbox confirming the problems and I reproduced the issue easily on my own Mac OS X testing computer.

A fix is being worked on and I hope to release it in mid August.

Edit - added a workaround

Edit 2 - a new build has been released that allows bliss to run inside a DMG file but not if copied elsewhere (e.g. Applications) - I'm talking to Apple about this!

Edit 3 - it appears that you can copy the file from the DMG if you use the command line, e.g. 'cp -r' rather than Finder. Maybe other Finder alternatives may also work.

Edit 4 - A full fix with support for copying to Applications and elsewhere is now in beta, expected release 28th August.

What's the problem?

The normal bliss.dmg file can be downloaded and opened as before. The problem comes when the bliss application is launched.

Confusingly three varieties of error message have been reported. These pop up when the bliss application is run. These are:

bliss is damaged and can't be opened. You should eject the disk image. You can't open the application

The above two messages are shown when running bliss directly from a DMG file.

You can't open the application bliss because it is not supported on this type of Mac.

This is shown if you install bliss as an OS X Application and attempt to run the app from there.

First, a workaround

I've found a workaround to allow bliss to be run directly from a DMG file. This does not work for running bliss from your Applications folder. The workaround is to disable Gatekeeper. This is, of course, undesirable and should only be done at your own risk. If you want to try this, do the following:

  1. Open System Preferences.
  2. Click Security & Privacy. You'll get the following interface: Screenshot of Gatekeeper for the workaround to run bliss on Mountain Lion
  3. Click the padlock icon at the bottom-left corner and enter your administration username and password.
  4. Under Allow applications downloaded from: choose Anywhere

You should now be able to run bliss direct from your DMG file.

What's the solution?

I'm working on it! I've replicated these error messages and I'm working on the assumption that correctly signing the application will solve all varieties of the problem.

I'll update the blog, Twitter, Facebook and G+ with progress.
