Rhino 7 evaluation for Mac

Hi,
Since downloading the evaluation of rhino 7 on mac, every file I create on it will not open once closed for the first time, no matter the file size or contents of the model. However when i import the file in to a new file it imports fine, but once saved again, it will not open. Im not sure if its a bug linked to the OS Big Sur update, but is very frustrating that I have to import every model in to a new file every time. Is there any solution to this?

Thanks
Thomas

We believe we have fixed (at least one) of these problems in the recent Rhino 7.3 update. Please let us know if you’re still having trouble opening files after you update.
