Apple has more details here.iPhone MirroringPhotograph: AppleSometimes your iPhone is in another room or deep in your bag. For those times when you need to use it but just don’t want to wake up to find it, you’ll be able to pull it up on your computer. As part of Apple’s Continuity feature, iPhone Mirroring gives you the ability to access and interact with your iPhone wirelessly using your Mac. When the feature is active, you’ll see your iPhone’s custom home screen appear. From there, you can use your keyboard, trackpad, or mouse to drag and drop content (like photos, videos, and files) between the two devices, open and use any app, swipe through any page on the home screen, as well as view and respond to notifications. When you do all this, your iPhone will remain locked. It also works when your iPhone is in Standby mode, a feature from iOS 17 that turns your iPhone into a smart display while charging.Safari UpdatesPhotograph: AppleMacOS Sequoia offers several new features for Safari. With Highlights, Safari will use machine intelligence to show you relevant information from web pages such as directions, links, summaries, and restaurant reviews. Apple also redesigned Reader to reduce noise. In addition to a more streamlined article view, you’ll also see a summary and table of contents (for longer articles). If the web page includes video, the Viewer will bring it to the front while still giving you access to playback controls (Picture in Picture included). which helps organize it for a better viewing experience. When you drag a window to the edge of the screen, the new OS will automatically suggest the position of the tiles on the screen. (It’s similar to Snap in Windows.) You can then drop windows into place, arrange multiple windows side by side, or place them in any of the four corners to make room for other apps. For faster organization, you can also use keyboard shortcuts and menus. VideoPhotograph Conference Tools: Apple Last year, Apple added many new video conferencing tools with macOS Sonoma including Presenter Overlay, Reactions, and various features for the Mac’s built-in webcam. This year, the company added a few more. With apps like FaceTime and Zoom, you’ll have access to new presenter preview capabilities that let you see what you’re about to share before actually showing it. Meanwhile, the built-in background feature allows you to apply system wallpaper, color gradients, or your own photos as background for video calls. Apple says this feature will be available in FaceTime and third-party apps like Webex. A New Sands AppPhotograph: AppleIf you never loved Keychain, now you have a better option: macOS Sequoia comes with a new Passwords app that lets you access all your passwords (including Wi-Fi password), password lock, and verification code in one place. It keeps all Apple devices in sync, runs on Windows machines (using iCloud for Windows apps) as well, and supports end-to-end encryption. More With MessagesPhotograph: AppleA few new Messages features come to macOS Sequoia-and by extension, for iOS 18 and iPadOS 18 as well. You’ll be able to format text in Messages using bold, italic, underline, and strikethrough type treatments. You will also have the ability to add animation effects to certain words in the text. For some phrases and words, you’ll also see suggestions appear as you type. Apple also added new Tapbacks—instead of using the traditional heart, thumbs up, thumbs down, question mark, or exclamation mark, you’ll also see the option to use emojis and stickers. Another notable new feature is the option to schedule messages in advance so they can be sent later. all can be filtered by elevation, length, and route type. You’ll also be able to save it to access the map when you’re in the wilderness without a data signal.

You will also be able to see your calculation history. Calendar: In the Calendar app, you can view events and tasks from the Reminders app. There’s also an updated Month View that’s meant to make it easier to see all your appointments at a glance—all color-coded.Photos: The new Collections feature in the Photos app will automatically organize your library by topic including Travel, Recent. Day, and People & Animals. With Pinned Collections, you’ll be able to quickly access specific collections and albums. You’ll also now see your Favorites album appear in Utilities and in Pinned Collections. You can delete the Recently Shared album and Viewed history as well. Game Mode: This feature was originally announced last year, with macOS Sonoma. With macOS Sequoia, Apple is adding Game Mode with smoother frame rates and “advanced power management features” to improve performance on Macs. It also supports Personal Spatial Audio and reduces audio latency with AirPods Pro (2nd generation). Home App: Apple adds guest access that lets you manage how and when people can enter your home. There’s a new feature that shows you how much electricity you’re using and how much it’s costing you, based on current utility rates.Battery: The ability to enable Low Power Mode was introduced with macOS Monterey. It’s now available in the Battery menu in the top left corner of the screen so you no longer need to dig into System Settings. Find Me: In the Find Me app, you’ll now see a new Lost AirTag section that lets you share your AirTag location with up to five other people, to help track it down. Soon, you can also share it with the airline (if your luggage is lost). Simply send specific links via Messages, Notes, Mail, AirDrop, and more. They must authenticate using an Apple account, and the link will expire after a week.Features Apple IntelligencePhoto: AppleIn addition to the above features, Apple Intelligence—the company’s “personal intelligence system”—is also built into macOS Sequoia. as iOS 18 and iPadOS 18.
