I foolishly updated my Macs to the latest OS (Sierra) without checking for compatibility with Squeak. No recent (all Cog?) VMs will work. The VM launches but no window appears. The problem appears to be addressed in OpenSmalltalk macOS Sierra Support issue #39 (https://github.com/OpenSmalltalk/opensmalltalk-vm/issues/39). It's marked as 'Closed'. Are there plans to include this fix in the official Squeak release?

I see that I can download and build my own VM from the Open Smalltalk site but I've never done this before, it looks a little ominous....

Perhaps a note in Squeak News and on the Squeak website would help to warn other users that they will not be able to run Squeak if they upgrade their OS.
