12 Best Mac Settings to Change on Your New Mac

A new Mac is ready to use the moment you turn it on, but its default setup is designed for a broad range of people and situations. A few thoughtful adjustments can make it feel much more personal, focused, and dependable. These are the best Mac settings to change first if you want less distraction, stronger privacy, and a smoother everyday workflow.

The names and locations of a few controls can vary slightly between recent macOS versions. Start by opening the Apple menu, choosing System Settings, and using the search field at the top when you cannot immediately find an option.

Best Mac Settings to Change for Daily Use

1. Adjust your Dock and desktop

The Dock is useful, but it can quickly become crowded with apps you rarely open. Remove an app by dragging its icon away from the Dock until you see Remove. This does not uninstall the app. Then add your most-used apps by opening them and choosing Options > Keep in Dock from their Dock icon.

In System Settings > Desktop & Dock, consider turning on Automatically hide and show the Dock. This gives you more room for documents and browser windows while keeping your favorite apps one pointer movement away. You can also choose a smaller Dock size and turn off the recent applications section if it creates visual clutter.

On the desktop itself, keep only active files and folders. A clean desktop is not just cosmetic. It makes screenshots, screen sharing, and finding current work much easier. Use folders in Documents, Downloads, or iCloud Drive for files you need to keep.

2. Set up Hot Corners with care

Hot Corners let you trigger an action by moving the pointer into a corner of the screen. In System Settings > Desktop & Dock, scroll down to Hot Corners. A practical choice is setting one corner to Mission Control, which shows all open windows, and another to Quick Note, which creates a note without interrupting your work.

Avoid assigning actions to every corner. If a corner is used accidentally, it can become frustrating. You can require a modifier key, such as Command or Option, before a Hot Corner activates. That extra step is particularly helpful if your pointer often reaches the edges of the screen during normal work.

3. Make Finder easier to use

Finder is where much of your Mac organization happens, so a few changes here pay off every day. Open Finder, then choose Finder > Settings. Under General, set New Finder windows show to your home folder, Documents folder, or another location you use often. For many people, this is more useful than opening Recents by default.

Under Sidebar, enable the locations you want quick access to, such as Documents, Downloads, iCloud Drive, your user folder, and any external drives. In Advanced, turn on Show all filename extensions if you regularly work with files that look similar but behave differently, such as PDF, JPG, and PNG files.

You may also want to turn on Keep folders on top when sorting by name. It prevents folders from disappearing among individual files and makes navigating a busy folder less tedious.

Reduce Interruptions Without Missing What Matters

4. Review notifications app by app

Notifications are useful when they help you respond to something timely. They become distracting when every app is allowed to demand attention. Go to System Settings > Notifications and review the apps one at a time.

For social, shopping, games, and many news apps, you may want to turn off Allow Notifications entirely. For communication apps, consider keeping notifications on but changing the alert style to Banners. Banners appear briefly and then disappear, while Alerts remain on screen until dismissed.

Pay attention to badges as well. A large number on an app icon can create pressure without providing useful information. Turn badges off for apps where the count does not help you take action.

5. Create a Focus for work, personal time, or sleep

Focus modes let you control which people and apps can interrupt you at different times. Open System Settings > Focus and create a Work Focus, for example. Allow calls or messages from the people you need to hear from, then allow only essential apps such as Calendar, Reminders, Messages, or your work communication app.

You can schedule a Focus to turn on during certain hours, at a location, or when opening a particular app. If you use an iPhone or iPad with the same Apple Account, consider sharing your Focus settings across devices. This prevents your Mac from becoming noisy just because your phone is quiet.

A Focus should not make you unreachable in an emergency. Keep important contacts allowed, and test the setup for a few days before relying on it during a busy week.

6. Choose the right display and Night Shift settings

In System Settings > Displays, adjust resolution, text size, and brightness for comfort rather than accepting the first option you see. If text feels too small, choose a larger text option. A little more screen space is not worth eyestrain or leaning toward the display all day.

True Tone automatically adjusts the display’s color temperature to match ambient light. Many people find it more comfortable for reading and general work. However, photographers, designers, and anyone making color-critical edits may prefer to turn it off while working on images or video.

Night Shift reduces blue light by warming the screen in the evening. You can schedule it from sunset to sunrise or choose custom hours. It is a comfort feature, not a substitute for healthy sleep habits, but it can make late-night reading feel easier on the eyes.

Strengthen Security and Privacy

7. Turn on FileVault

FileVault encrypts the information stored on your Mac. If the computer is lost or stolen, encryption helps protect your files from being accessed by someone who does not know your login password. Find it in System Settings > Privacy & Security > FileVault.

When you turn it on, macOS will guide you through recovery options. Read these choices carefully. If you choose to manage your own recovery key, store it somewhere safe that is separate from the Mac. A recovery key is valuable because it can help regain access, but it also needs protection.

FileVault may be less suitable for a shared office Mac where an organization manages access differently. For most personal Macs, though, it is a sensible default.

8. Check login and screen lock settings

Open System Settings > Lock Screen and set Require password after screen saver begins or display is turned off to Immediately or within a short period. This is one of the simplest ways to protect your information when you step away for coffee, a meeting, or a conversation.

Set the display to turn off after a reasonable period of inactivity, too. Shorter times save battery on a MacBook and reduce unnecessary energy use on a desktop. You can still adjust this temporarily when presenting or reading a long document.

If your Mac supports Touch ID, add a fingerprint in System Settings > Touch ID & Password. It makes secure sign-in and password approval much more convenient, which means you are less likely to choose a weak password for the sake of speed.

9. Limit unnecessary app permissions

System Settings > Privacy & Security shows which apps have requested access to your location, camera, microphone, contacts, photos, and more. Review these categories periodically. Ask a simple question: does this app need this information to do the job I expect it to do?

For example, a video meeting app needs camera and microphone access. A basic utility app probably does not. You can turn access off at any time, and macOS may ask again if an app truly needs a permission later. This is not about distrusting every app. It is about giving access intentionally.

Protect Your Work and Save Time

10. Turn on Time Machine backups

A backup is most valuable before something goes wrong. Connect an external drive with enough space for your Mac, then open System Settings > General > Time Machine. Select the drive and let Time Machine create automatic backups.

Time Machine keeps versions of your files over time, which is helpful when you accidentally delete something or need an earlier version of a document. iCloud Drive is useful for syncing files, but syncing is not the same as maintaining a complete backup. A deleted or changed file can sync across devices.

If you travel with a MacBook, leave the backup drive connected when you are at your desk. The less effort a backup requires, the more likely it is to happen consistently.

11. Review Software Update settings

In System Settings > General > Software Update, turn on automatic updates for macOS and security responses if you are comfortable letting your Mac install them. Security updates often address issues that are not visible to you, which is exactly why they are easy to postpone.

If you rely on specialized work software, older printers, or professional audio and video tools, you may prefer to wait briefly before installing a major macOS upgrade. In that case, keep automatic security updates enabled and schedule time to update after confirming your important apps are compatible.

12. Customize the trackpad or mouse

Your pointing device affects nearly every task you perform. In System Settings > Trackpad, turn on Tap to click if you prefer a lighter touch, and explore gestures for Mission Control, App Exposé, and switching between full-screen apps.

For a mouse, visit System Settings > Mouse and adjust tracking speed until the pointer moves comfortably across the display. There is no universally correct speed. The right setting is the one that lets you select text, move windows, and work across multiple displays without repeatedly overshooting.

Small adjustments are often the ones you feel most. Choose two or three settings that solve a real annoyance, use them for a few days, and then continue. A Mac becomes easier to manage when its setup reflects how you actually work, rather than how it arrived out of the box.
