Just like the Messages app in iOS, the Messages app on Mac allows you to send and receive attachments via iMessage or SMS. Over time, these attachments can take up a lot of storage space and even keep a running history of the things you’ve been sending and are receiving if they’re not dealt with.
In this tutorial, we’ll show you how you can go through your attachment history in your Messages conversations to delete unwanted attachments that are eating up your storage space.
Attachments in the Mac’s Messages app
Attachments can come in many forms, whether that might be an image file, video file, document, spreadsheet, PDF file, audio file, or something else. In any case, they use up storage space on your computer, and it also takes up valuable resources on your computer to constantly load those attachments when you look through your messaging history in your Messages app.
In terms of privacy, keeping all your sent and received attachments in your Mac’s Messages app leaves you wide open for snooping, especially since you’re likely to leave your Mac turned on throughout the day and the auto-lock function on the Mac is set far longer than on any iOS device by default.
How to delete attachments from the Mac Messages app
If you’re like me, then you probably send and receive a lot of attachments in iMessage or SMS with your friends, co-workers, and your significant other. You can use a function built into your Mac’s Messages app to easily delete attachment histories in bulk so you don’t have to waste any time going through your conversations deleting attachments one-by-one.
Obviously, you should save anything of importance before canning it. If you’ve already done that, then you actually have two copies of the file saved locally on your computer – one in the Messages app attachment archive, and one wherever you saved it to. If you haven’t already saved a copy of important attachments, we’d recommend you do that before starting this guide.
To delete attachments in bulk from the Messages app on your Mac, you can follow these simple steps:
Step 1: Launch the Messages app on your Mac and click on a conversation you’ve had recently.
Step 2: From the Messages app interface, click on the blue “Details” button at the top right of the app.
Step 3: A pop-up menu appears, showing you all of the attachments sent and received in this conversation:
Step 4: Hold down the Command (⌘) key on your keyboard and click on all the attachments in this pop-up menu you want to delete; they will turn gray to indicate they are selected.
Step 5: With one or multiple attachments selected, right click on one of them to display a menu; click on the Delete button from that menu.
Step 6: In the pop-up confirmation that appears, click on the blue Delete button to confirm your action.
Step 7: The attachments you deleted should now disappear from the “Details” menu in the Messages app, as well as from the conversation you were just in.
That’s all there is to it! You’ve just deleted a bunch of attachments in bulk from a conversation in your Messages app on your Mac. You can do this for each of the individual conversations in your Messages app, and we’d highly recommend doing so for privacy and storage space.
Will this delete the attachments from my other devices too?
This process only deletes the attachments from the one device you’re doing it on. This means that if you have multiple iPhones, iPod touches, iPads, and/or Macs tied to your iCloud account, then they’re still going to have all the attachments on them if you follow this process on your Mac. In which case, you’ll have to bulk delete attachments from your iOS Messages app as well.
With that being said, you’ll need to delete attachments from each of your other devices individually. Fortunately, the process isn’t too painful and it’s quick and easy.
Keeping your attachments cleared every so often, even if it’s just every couple of weeks, can dramatically improve your privacy and can even help you save storage space on your computer from filling up too quickly.
