How can I delete all messages on my Mac?

I realized my message app on Mac has too many old conversations taking up space. I’m trying to clear them all at once, but I can’t find a simple way to delete everything. Can someone explain how to do it?

Oh, the horror of digital clutter! Your Mac drowning in a sea of old messages—it’s a tragedy Shakespeare would write about if he lived in the age of iMessage. But fear not, for a cleanup is possible, though Apple doesn’t make it blatantly obvious. Here’s how you can handle your digital hoarding problem:

  1. Manually delete chats: Open the Messages app on your Mac, right-click (or Control-click) on the conversation(s) you want to purge, and hit Delete Conversation. A pop-up will ask, “Are you sure?” Yes, Apple, we are sure. Click Delete again. Painstaking if you’re dealing with hundreds of chats, but hey, manual labor can be spiritually cleansing (or so I’m told).

  2. Adjust settings to avoid an eternal message vault: Go to Messages > Preferences > General and set Keep Messages to 30 days or 1 year instead of “Forever”. Why do we even need the “forever” option for texts? Do we think our mundane “lol”s and thumbs-up emojis are future historical artifacts?

  3. For the nuclear option: If you want it ALL gone, there’s a more savage approach. Close the Messages app and head to Finder. Navigate to ~/Library/Messages/ (you can get there fast by pressing Command + Shift + G in Finder and pasting that path). Trash the following folders and files:

    • chat.db
    • chat.db-shm
    • chat.db-wal
    • The Attachments folder (where all your glorious pictures and GIFs live).
      Keep in mind, though: this wipes everything. No second chances.
  4. Empty your trash (because we all forget that step and wonder why we’re still enslaved by the ghosts of past texts).

Now breathe. Your Mac should feel lighter, faster, and blessedly free of that 5-year-old group chat where everyone just sent eggplant emojis for no reason.

You could also embrace the power of automation (gasp, imagine letting the computer do the work). @techchizkid already laid out the manual and Finder options, but here’s a take: if you’re not about diving into folders and chucking out files like you’re on an archaeological dig, consider scripting. Yep, you can use AppleScript or even Automator to batch-delete messages from your Mac.

Now, this might still require some Googling for the exact script, but if you’re tech-curious, it’s worth a shot. Basically, you’d write a little script to go through and nuke everything in your Messages app. Or, if advanced coding makes you cringe, third-party cleanup tools exist. Proceed with caution, though—some of those tools can be a bit sketchy (always check reviews and avoid the too-good-to-be-true ones).

Also, can we collectively agree that Apple’s ‘Forever’ message retention setting feels a bit unnecessary unless you’re writing a novel through text? Just switch it to a shorter period like @techchizkid said, and future-you won’t be here searching “how to delete everything” again.

So yeah, manual and Finder are solid options, sure, but thinking outside the box with scripts or tools doesn’t hurt.

Oh man, isn’t it funny how our Macs just pile up with everything, including text messages? First off, both @suenodelbosque and @techchizkid have laid out great options—manual delete or Finder clean-up—but let me spice this up by mentioning another angle and maybe poking a few fun holes in the process.

If we’re being real, digging around Finder to trash files like chat.db feels like dungeon crawling in a 90s RPG. Effective? Sure. Simple? Not really. Let’s talk about a slightly different approach that keeps you from accidentally deleting something crucial and avoids turning this task into an advanced coding class.

PRO TIP: The Power of iCloud Sync Deactivation
If your messages are synced with iCloud, deleting them might just redownload everything back—Frustration Level 9000. So, turn off your iCloud Message sync temporarily before fiddling with deletions:

  1. On your Mac, go to System Preferences > Apple ID > iCloud and uncheck Messages.
  2. If needed, also disable on your iPhone (Settings > [Your Name] > iCloud > Messages).

This prevents the ghost of your deleted messages from haunting you. Once everything’s wiped and your Mac is squeaky clean, you can turn it back on.

Storage Management FTW
Instead of diving into Finder guesswork or scripts, consider using macOS’s built-in storage management tool. Here’s how:

  1. Click on the Apple logo > About This Mac > Storage > Manage.
  2. Look at Messages to see if it’s hogging storage. You can free up some space directly here without going nuclear by selectively managing files like attachments or older conversation threads.

Bonus: Third-Party Apps
If Finder adventures or scripting sounds about as appealing as eating expired yogurt, you could try third-party cleanup apps like CleanMyMac X (popular, user-friendly, but it’s paid) or MacKeeper (has a reputation for being a little spammy, but it gets the job done). These tools often come with fancy one-click options to handle iMessage file deletion alongside other Mac-cleaning features.

Trade-offs of This Approach?

  • Pro: Avoid manual guesswork and spend less time in Finder.
  • Con: Third-party apps might cost money or come with those pesky ‘upgrade now!’ pop-ups.

Honestly, the “Forever” option lurking in iMessage preferences feels like a black hole that tech-savvy Shakespeare could write a tragedy about. Pulling the plug on that setting entirely (like @techchizkid suggested) feels more practical for future peace of mind than venturing into Finder every year for a massive purge.

Lastly, let’s agree Finder cleaning isn’t up everyone’s alley, and manually deleting chats might just push you into an existential spiral. Scripts might work if you’re into nerdy puzzles; otherwise, iCloud tweaks and storage tools are smart moves without diving into the trenches. Can we normalize not keeping that four-year-old message saying ‘Hey, what’s up?’? Because nobody needs that energy in 2023.
