Bought my wife a new MacBook Air for Christmas and now the Reply, Reply All, and Forward buttons causes Mail to crash. I have tried rebuilding all the mailboxes, but it is still crashing.
Mail is basically unusable at this point.
Attached is a screenshot of the error report.
MacBook Air 13″, macOS 10.15
I would start by updating your MacOS to the current version 11.1, either a bug fix or simply reloading all the OS and software might provide an easy solution.
If a full reinstall doesn’t fix it you should probably report it as a bug at https://www.apple.com/feedback/. Yes a MacOS bug or a device bug but my preference would be for the software.
Just upgraded to MacOS 11.1 and this did not work.
I have been digging into this and I found that it starts to bring up a new window before it crashes.
Also, I have notice that some e-mails work and most don't. It happens on all my inboxes. At one point, I thought it had something to do with the weird TO: line in my e-mails. It looks like this: "my e-mail address My Name <my e-mail address>". Some e-mails don't show the TO: line in the display panel. Those seem to work. However, I'm finding some with the weird TO: line that work too. So that's not it.
In addition, the Junk and Trash mailboxes are no longer listed under favorites, They are all separate for each inbox now. I prefer to have junk and trash go to one corresponding mailbox, not 4 separate ones.
