Hi Beryl,
You need give yourself permission to do this with the current OS.
I sent you a unix command to type into terminal. You will have to enter your password after typing it, but you will NOT see your password typing as you enter it. If you mistype it it will say something to the effect of sorry wrong password. if you type it correctly - you won’t get much back from terminal other than a new command line. after entering your password correctly - please try and install your curves again. or just continue replying to me in the email you started earlier this morning…

For those who have the same issue, and to save Jon having to send this out several times to several people who all have the same problem, the command is listed on this thread:
