the mail app on my iMac (Sierra 10.12.6) keeps closing. The computer develops a report that I send to Apple. I also run a Macbook Air on which this does not occur which suggests there is an application on the iMac but not on the Macbook causing this. How should I approach fixing this?

Please rebuilt each of the mailboxes and and then retest.
Mail- Mailbox - Rebuild
If that does not work, please reset the NVRAM and restart in Safe Mode.

thanks for this response. I followed the instruction: Mail-Mailbox-Rebuild. After clicking rebuild I saw no action. That is, no drop down in case there were subsequent selections to be made and no sign that a rebuild was happening, .
Should I therefore go to reset NVRAM?
This was helpful in that it pushed me to search for a reason why the the version upgrade wasn't working which i rsolved so indirectly you fix3d this for me. thanks Mike
Well if the Mail app is having the same problem, yes reset the NVRAM.
