Mac version 5.5 breaks layouts?

I just update to 5.5 and now my layout pages are all black… If I pop up the print panel, the pages are rendered correctly in the preview… but nothing on the layout window (and by correctly, I mean as incorrect as it was before, as it looks like the clipping plane edge rendering is not addressed in this release.)

Any one else running into this?

We saw this, yes. MR-3250
In Preferences > Colors, pressing Restore Defaults should fix that.

Yes, that cleared it up. Thanks!

Only fixes the issue while using the current session—once the app closes and reopens, issue returns.

We have an open bug item for it.

This issue should be fixed in the 5.5.1 update to Rhino 5 for Mac.
