Emails with drawing attachments receive a message that file is downloading - try later. It never sends.
This is a major problem. Solutions?

You're trying to send a .dwg file using Apple email software and doesn't work? This is an issue not related to our software, it's related with Apple software so you need to contact Apple for support or use another email client software that works properly.

Thanks. I went to Apple Support, spent several hours, ran disk first aid and after 8 hours the emails started sending. Hope it keeps working.
