Need help to solve a computer problem.

Background:

My 9 year old Apple MacBook Pro quit. Took it to the Apple store and they said the hard disc failed. Time for a new computer. Got new MacBook Pro loaded with MacOS Mojave 10.14.6. I had backed up the old computer about a month ago on a Samsung external drive with all my data and applications. All migrated to new computer but with a problem. The AutoCAD program came up with a message when I tried to load it.

“Folders on your computer that AutoCAD needs access

to are not available. AutoCAD cannot run until folder

permission issues are resolved.”

The old computer was running on MAC Lion os and the AutoCAD version I have is: vs 2015, 20.0.51.455. I am thinking that the problem lies with the “permissions settings” on the new MAC . I need a step by step procedure to fix the problem. Can anybody help. I know how to do my drafting with the AutoCAD program, but am really lacking on computer savy. Thank you.
