Note that Shion 3.0 is currently in alpha. This means that the app is incomplete and buggy and mainly intended for testing purposes. Unfortunately, MacUpdate insists on posting each and every release (independent of developers' wishes), so use this release at your own risk.

To my knowledge the developer has never contacted us requesting that we don't post pre-release versions.

It has been MacUpdate's policy for 14 years to publish the latest publicly available release... we try to always link to the most recent stable release in the Related Links field.


I haven't made any requests with respect to Shion, but we did this song and dance a couple of years ago with Books alpha releases. My takeaway from that conversation was that if it's public, MacUpdate can't afford to not post it, otherwise VersionTracker would steal your thunder.

Apologies for not contacting you with respect to Shion. My experience with Books led me to believe that it would be a wasted effort. However, I would appreciate it if you would flag Shion as a product that only gets updated on this site by its developer, and not part of an automatic process. If I can't get this product flagged in this way, my original point stands.


If you would like us to omit alphas/betas, we now respect that if the developer requests. We want to make sure that we're as "with" you as we can be, and not "against" you -- we exist to benefit developers and respect that without developers we wouldn't exist.

Having said that, we'll continue to auto-update posts ourselves with stable releases. Too few developers directly submit updates to MacUpdate and fewer do so in a timely fashion, so it's imperative we take the initiative ourselves for us to continue our relevancy and to deliver the service our users expect.

You can always email me at misha@ -- I'll be happy to dialogue with you further about this.

If you're having problems running Shion and have installed Indigo in the past, you need to remove a bit of software that Indigo installs into your system that prohibits other applications (such as Shion) from accessing your Insteon software. See


My apologies for the inconvenience, and I'll be adding a detector for this file in the next release of the application.
