For the last year (possibly longer) the Mail app on my iMac crashes after I close the window (not quit, just close using the red X button in the top left corner, or with cmd+w). This happens 100% of the time without fail. I submit a crash report to Apple each time but it seems like this isn't addressed. Note, I only have one account connected and that is my iCloud. Things I've tried:

I'm out of ideas besides reinstalling macOS but that's my last resort. Here's part of the crash log:

Edit to add detail:

When I disable my iCloud account in preferences, I can close the app without it crashing. But as soon as the account is re-enabled, it goes right back to crashing on close.

Another thing I noticed is that if I click the "Mailboxes" button to show all mailboxes (eg, Inbox, Flagged, Sent, etc). I can switch to any other mailbox and close the app without problems. It only crashes if I have the Inbox selected and close the app.


Opened Console and tracked error messages from Mail app. Here are the results, all of these errors are logged multiple times except the AEGetDescData error.

Error sending searchable item 29964 to CoreSpotlight:Error Domain=CSIndexErrorDomain Code=-1000 "(null)"

[AOSAccounts] : [ACAccount+iCloudAccount] : -[ACAccount(iCloudAccount) icaCloudKitToken] - icaCloudKitToken cannot be returned as account is still not vetted!

AEGetDescData of non-desc type 'reco' not a good idea


A lot of events are logged in Console. I cleared the console before closing Mail, here's a screenshot with all the messages (my email address blurred out).

  • Not a stupid question! Just with the red X button in the top left corner

  • Open Console, type Mail in search box so you only see Mail messages, scroll to the bottom, now Close mail and note what message you get.

While evaluating your Console report I came across nasty malware on your system called "ScorecardResearch"

Since it is interacting with your Mail and who knows with what else and it is clearly sending your information without your consent, I assume it is also responsible for the Mail error.

Get rid of it. https://www.2-spyware.com/remove-scorecardresearch-com.html

  • Thanks Buscar, that's the same site I googled yesterday but I didn't find any suspicious apps. I'm pretty careful about what I download. I got rid of any apps that I don't use in a while so hopefully that helps. I also deleted any weird extensions from Chrome. I haven't seen any mentions of scorecard since. As for the Mail app not working, I am trying one more thing: sign out of iCloud completely on the mac and sign back in

  • Oops spoke too soon. Scoreshit appeared again. I have no other suspicious apps. Any recommendations on what to do?

Problem resolved itself after installing macOS Mojave! Thanks everyone for the input!
