iMessage is a cornerstone of the Apple ecosystem, often keeping users loyal to their devices. With each macOS and iOS update, Apple enhances the Messages app to rival competitors. macOS Big Sur revolutionized the Mac version, bringing iPhone-like features to the big screen. As Apple experts who've tested these firsthand, here are eight standout capabilities to elevate your messaging experience.

The revamped Messages app in macOS Big Sur is now a Catalyst app, delivering identical functionality across Mac, iPhone, and iPad—including mentions, inline replies, and pinned group chats.
Pinning conversations is a game-changer for frequent users. Pin up to nine key threads to the top of your list for instant access. In pinned group chats, recent messages trigger animated Memoji or avatars around the pin, signaling activity.

You'll also preview photos from the last three participants. Right-click (or two-finger tap) a conversation and select Pin. To unpin, drag it back to the main list.
Click the info (i) button in the top-right of a group chat, then Change Name and Photo. Enter a custom name, select auto-generated images, pick from Photos, choose an emoji, or add a Memoji.

In lengthy threads, inline replies keep context clear. Hold Option and click any message to reply specifically—ensuring the recipient knows exactly what you're addressing.

One minor note: It can briefly reorder the thread, but the clarity outweighs it.
Long-awaited @mentions are now here, matching apps like WhatsApp. Type @ followed by a name, select from the popup, and notify them instantly in group chats.

Tailor alerts in group chats to ping only on mentions—even if muted. Perfect for staying in the loop without constant buzzes.
GIF lovers rejoice: Search and share directly via the App Store icon (#images tab) next to the text field—no app switching required.

Add flair with effects like Slam, Love, Fireworks, or Invisible Ink. Click the effects button to choose—use sparingly for maximum impact with friends.

See when others are typing right in the chat list, borrowed from top apps for smoother real-time chats.
