Cannot open RhinoOSX on my computer

I cannot even open the program with the latest download. I have a macbook running system 10.7.5, Processor 2.16 GHz Intel Core 2 Duo, 4 GB 667 MHz DDR2 SDRAM. Any ideas?

I assume there was some sort of error message with the failure.
Any chance you could post that so we had something to go on?

Thanks for responding John. Here is what shows up on my screen.

See this…

This error dialog has nothing to do with dropping support for 10.7.5 in the future.

You have a corrupted Rhinoceros application. You need to throw away your copy of Rhino in your Applications folder and download a new copy of the installer and reinstall Rhino.

Did this copy of Rhino in your Applications folder previously start? If it did, then this is an indication of more serious problems. Applications don’t start mysteriously failing without reason. Your hardware, possibly your disk drive, is likely failing. Be sure to have current backups, and make plans for replacing your computer when it fails completely.

OK, sorry for the dis-info… --Mitch

Thanks Marlin. The copy that wouldn’t start was a brand new download. I have a hunch that its the hard drive. Walter
