Don’t Allow Attachments To Automatically Download

There is a setting that allows all attachments to automatically download in the Mac mail program. This isn’t a good idea for obvious reasons, you can help prevent trojans by simply not downloading attachments, unless you are sure they are safe. I recently received a Trojan in a word document emailed to me with the heading “Here’s My Resume” It didn’t come from anyone I recognised. To turn off automatic downloads follow instructions below and untick Automatically download all attachments. Open Mac Mail-Accounts-Select an email account-advanced-untuck Automatically download all attachments.
