I'm afraid to try the beta versions anymore. I've had enough trouble to deal with on final releases on Mac since v8, and with no feedback on bug reports, it feels pointless filing issues that may not be relevant to anyone but me. I might have better luck had I not many years of stuff installed under older folder systems and from several previous versions of Carrara, but I do. I may have simply run into an immoveable wall, of frustration or obsolescence or both.
