Sketchup 2024 download not opening on MAC

I feel like a fool asking here, but I’ve downloaded SKU 2024 and clicked on it… Nothing. No mounted drive or window to install the file. I’ve just updated my Macbook to sonoma. The downloaded file has as the extension to it. Any suggestions?

.download is usually a temporary extension appended while a download is in progress, automatically removed when it completes. The installer should be just .dmg Either you didn’t wait long enough or for some reason the download got stuck. Try downloading again.

Thanks, that did the job.
