How to Open Email Attachments in Mac Mail

Authored by: Support.com Tech Pro Team

1. Introduction

Many times, important documents are sent via email as an attachment, rather than a link or as the text of an email itself. This guide will help you understand how to identify an attachment in the Mac Mail program, how to open them, and some common issues you may encounter when working with attachments.

2. Opening Attachments in Mac Mail

Most of the time, you will want to just open the attachment directly. If you wish to save the attachment, expand the section below for more detailed instructions.

Opening an Attachment

1. Select a message with an attachment, then double-click the file shown in the message itself.
   

1. The attachment will open automatically using the appropriate program on your computer. You can then view, edit, or print the document.

3. Common Attachment Problems

There are two common problems people encounter when it comes, and both tend to be simple human error. Understanding these problems can help when working with the sender to resolve them quickly.

Message References A Non-Existent Attachment

People often send messages quickly, without thinking, and while they meant to attach a file, forgot to, but still refer to it in the email. It can be confusing what's going on because of this. Windows Mail makes it fairly easy to recognize, if you know what you're looking for.

In the above image, ther text says there's an attachment, but it doesn't appear. That's because the sender didn't attach anything in the first place; a simple human error. You can tell because there's no paperclip icon next to the mail message on the left, and there's no file blocks above the message on the right.

The best solution is to reply to the mail, and let the sender know they accidently forgot to include the attachment, and to ask them to re-send it.

No Program to Open Attachment

Another common issue is people will send you a message in a format or type that you cannot open, because your computer lacks the program to do so.

If you open an attachment, and see a box asking how you want to open a file, it means you don't have the exact program needed to look at the contents of that file. It is possible to search the Internet, the App Store, and other places to attempt to determine exactly what kind of file it is, then figure out some program that will allow you to open it. The problem is that is a lot of guess-work on your part often times, and, again, usually can be solved much more simply by speaking with the person who sent you the message in the first place.

While it used to be true that you'd need to do the 'leg work' on this, that's really not the case anymore. Most document programs can easily create a PDF, or Portable Document Format of the file, that can be opened easily by macOS directly. Most image programs can export, or save the file in an easier format for everyone to understand, such as PNG or JPG. All of these options are a lot easier than spending hours trying to figure out what you've been sent, but they rely on you talking to the person who sent you the document.

Reply to the message, and let the sender know they sent the document in a format you can't use. Ask them to export it in a more-accessible format; this is quick and easy for the vast majority of software out there.

If they're unable to save the file and re-send it in a different format, the sender will know what program they used to make the file in the first place, and tell you so you can download or purchase the appropriate program.
