Erasing a Mac and returning it to factory defaults has never been easier, thanks to the addition of a “Erase All Content & Settings” feature introduced in newer versions of macOS system software. Gone are the days where you had to manually erase and then reinstall system software, now you can simply let MacOS handle the task for you by choosing to erase and factory reset the Mac through a handy built-in feature.

The approach is available in macOS Ventura and newer only.

Be sure to back up the Mac with Time Machine first! Proceeding will erase all data, files, and information from the computer. This will erase all data on the Mac. Do not proceed unless you have backups of your data. Failure to backup will result in permanent data loss!

• Pull down the  Apple menu and go to “System Settings...“
• Go to “General“
• Choose “Transfer or Reset”
• Click on “Erase All Content and Settings”
• Confirm that you want to erase everything, log out of your Apple ID, and remove all data from the Mac by clicking “Continue”
• Follow the onscreen instructions to complete the process

When the Mac has finished factory resetting and erasing everything, a freshly installed version of the current version of macOS will boot into the typical “Hello” screen. Assuming you’re going to be gifting this Mac or selling it, you probably do not want to set it up yourself, instead let the recipient handle it.

This same factory reset feature also exists in macOS Monterey, but it is accessed slightly differently on those Macs. To factory reset a macOS Monterey Mac, go to the  Apple menu > System Preferences > System Preferences menu > Erase All Content And Settings. Be sure to backup all data beforehand, as usual.

Add Apps to a Hot Corner. Setting up Hot Corners is very easy:

• Go to the  Apple menu and choose "System Settings..."
• Click Desktop & Dock in the side column
• Click the Hot Corners... button at the bottom of the menu
• In the dialog that appears, click the chevrons to open the dropdown menu corresponding to the screen corner that you want to use and assign this corner to Apps, then click Done
• Now, you can open the new macOS Tahoe Applications overlay by taking the pointer to that corner of the screen

Add an Applications folder to the Dock:

• Open a Finder window
• Right-click over Applications in the sidebar and select Add to Dock
• An Applications shortcut will be added to the left of the Trash icon, click it to view all apps and open one (you can also right-click on this icon and change a few things)

Instead of checking your computer’s clock and manually typing the date and/or time, you can automate it using a shortcut. This also ensures you can fill in the precise current date and/or time without the possibility of an error. It involves two simple steps: creating the shortcut once and then using it whenever needed.

• Open the Shortcuts app and choose File > New Shortcut
• Type “Text” in the top right search field and double-click the Text action to add it to your build
• Click in the text field, start typing “Current,” and select Current Date from the suggestions
• Select a Date Format (you can also pick a format for Time or set it to None if you only want to insert the date)
• Click the triangle Run button at the top to test your build; you’ll see the date and/or time appear on the screen
• Click the info button (i) in the top right corner of the window and check the box for Provide Output
• Click Add Keyboard Shortcut and press the keys you want to assign to run this shortcut (for instance, Control + Option + Command + D)
• Give a name to your shortcut (for instance, Insert Date & Time) and save the shortcut by closing the window (hit the red traffic light button)
• Open an app like Pages, Text Edit or Google Docs in Chrome and press the key combination; you’ll see that the current date and/or time are automatically typed in

Customize Lock Screen Font

macOS Tahoe lets you customize the clock that appears on your Mac's Lock Screen. You can't adjust size like you can in iOS 26, but you can change the font style and thickness. To adjust your clock, go to System Settings > Wallpaper > Clock Appearance. You can choose from six different font styles, and adjust the weight with a slider. You can opt to have the clock show on your Lock Screen or on the Lock Screen and Screen Saver.

Search Your Tabs

When you search in Spotlight, the results include the Safari tabs that you have open. If you tend to have dozens of tabs open at once, it can be a good way to find the specific tab you're looking for rather than clicking through them one-by-one. Open tabs show up at the top of the list when you enter a relevant search term.

Safari Picture in Picture

Picture-in-picture has been available in Safari for several years, but macOS Tahoe brings easier activation, new controls, and customization options. In an article where there's a video, click on the Page Menu icon in the left side of the URL bar to enter picture-in-picture mode. You can now access playback controls for skipping forward and backward, and you can skip ads directly from the picture-in-picture window.

See Your Spotlight History

You can see your past Spotlight searches and actions in macOS Tahoe, which makes it easy to get back to something that you did before. With Spotlight open, press on the up arrow to scroll through your past queries.

Game Overlay

When you're playing a game in macOS Tahoe, you can tap Command + ESC to bring up a new Game Overlay. From the Game Overlay, you can view achievements and leaderboards, connect with friends, and adjust settings like brightness and volume.

Liquid Glass

macOS Tahoe has a new design. Buttons, navigation bars, widgets, the Dock, menus, side bars, and more all have a more translucent look that reflects the background underneath and refracts light. There are new icon options, including tinted and entirely clear.

Customizable Control Center

You can rearrange the Control Center in macOS Tahoe, putting what you access most often front and center. You're also able to use multiple Control Center pages, and add third-party app controls.

Customizable Menu Bar

You can also rearrange the Menu Bar, plus add Control Center controls to it. Live Activities from the iPhone will also show up in the Menu Bar now through ‌iPhone‌ Mirroring.

Spotlight Redesign

Spotlight is very different in macOS Tahoe, and it might take some getting used to. There's no more Launchpad, because the new Spotlight functionality has replaced it. There are four main Spotlight options to access apps, files, complete actions, and access the Clipboard History.

Clipboard

Spotlight now saves what you copy and paste, so you have a log of what you've been doing that you can go back and reference. You can see your entire history for the day, but it is limited to 24 hours.

Spotlight Actions

You can use Spotlight Actions to do all kinds of things without opening an app. You can send texts, emails, create shortcuts for features in apps, set timers, create Calendar events, make reminders, and much more, plus there's integration with the Shortcuts app to take things even further. There are quick access phrases you can assign to launch tasks quickly, like CH for bringing up ChatGPT.

Folder Customization

You can assign colors to folders, and also add an emoji or character to help you better organize your files. Folders get a color tag, which is a useful way to group things together.

Widgets

You can move widgets from the Notification Center to the desktop for quicker access. This works with widgets from Apple apps and from third-party apps.

Shortcuts

The macOS Shortcuts app supports creating automations. You can make Shortcuts that run at a specific time of day, with a trigger action, when an accessory connects, when an action in an app takes place, when the battery drains to a certain level, when activating a Focus mode, and more. It's super powerful when paired with Spotlight's new functionality.

Phone App

Apple brought the Phone app to the Mac, so you can make calls, accept calls, and use features like Hold Assist and Call Screening. You still need a connected ‌iPhone‌ with Wi-Fi Assist turned on.

Journal App

The Journal app is new to the Mac, and it makes a lot of sense on a platform that has a full keyboard. It works just like the iOS version of the app, but there are also some added features like the option to create multiple journals.

Games App

The Games app is also new to the Mac. It's a cross-platform app that aggregates Mac App Store games and Apple Arcade games with your own games library, plus it provides options for playing with friends. There's a new Game Overlay that lets you adjust game settings and connect with friends without exiting the game, and if you're on battery, there's a Low Power Mode so you can play longer.
