MacOS High Sierra Mac Mail Causing Mac to Reset When Opened

Hi,

Last week my iMac (mid-2010 model) began restarting for no reason. After doing some diagnostics I was able to determine it was my mail causing the issue.

I'm unable to open the mail to do any further diagnostics within the app. Before I did the step below I would open the mail and the iMac would just restart instantly.

So far I've tried to do the following

~/Library/Containers//Data/Library/Preferences - look for the and drag it to desktop and restart the mail.

When I reopen the mail now it will import 130,000 and once it has done that my iMac just restarts again.

Does anyone have any ideas on how to fix this issue?

Thanks in advance,

Stuart

Hi Stuart,

Let's start with this...

Safe Boot from the HD, (holding Shift key down at startup), does the problem occur in Safe Mode?

 Safe mode attempts to repair Disks & clears lots of caches, so if Safe Mode works try again in regular boot.

If still no good Disconnect from the Internet, then start Mail, look for the last rec'd eMail.

Quit Mail & login to your WebMail in a Browser, if possible delete any later eMails there after the last rec'd one on the Mac.
