Hello I have the problem can you please help?

Hello all,
Please contact your regional McNeel office directly (or your local reseller if you bought the upgrade there).

i have the same problem, did you get it fixed? if so, how?
got a project due Wednesday and rhino 7 doesn’t work good on the new Macs.

Hi Norris, i originaly had the problem now its fixed. I suggest you to contact tech support of rhino thats how i got it fixed they give you directions on what to do if nothing works at the end they arange a zoom meeting where they take control of your computer, thats how mine got fixed with the help of Brian Gillespie he was verry helpful. You can start by contacting them through this e mail.

Getting Brian involved is generally a last resort. This is most likely a folder permission issue.
