Problem free DaVinci Resolve 17.4.6 version

hey guys, for Mac OX, i tried several times to activate the program, after it was downloaded successfully.
After opening zip, Davinci_Resolve 17.4.6.dmg leads me to next 3 files. Clicking on Install Resolve 17.4.6.pkg,

brings an error : Cant be installed/ its digital signature is invalid. The package may have been corrupted or tampered with. Get a new copy of the package and try again.

do you have any suggestions? i tried many times during a day... no changes.. thank you, M

Is the installer downloaded from the Blackmagic Support page?

I had no such problem here with the download from BM's support page.

Uli,
Somebody had a problem with the 17.4.6 that the Speededitor wheel didn't work. You have no problem?
Thanks

Nope, it works.

I'm having the same problem with v18. Did you ever resolve the issue for you?
I've downloaded DR from the BM site and get the same message when I try to install on my Macbook:
"Resolve 18.1.1 can't be installed because its digital signature is invalid... etc"

I am already running 18.1.1 on a Windows machine with no problems, but wanted it on both machines (to replace Lightworks, which isn't nearly as good).
