Whether you use a MacBook Air, MacBook Pro, Mac mini, Mac Studio or iMac, macOS already includes many security features. Nevertheless, it is worth checking some settings carefully. Is FileVault enabled? Can you locate your MacBook if it is lost? Which apps can access the camera, microphone and files? And do you need an additional antivirus scanner on a Mac mini, Mac Studio or iMac at all? This guide shows the most important settings for making current Macs more secure and privacy-friendly.
The most important foundations apply equally to MacBook Air, MacBook Pro, Mac mini, Mac Studio and iMac: keep macOS up to date, enable FileVault and Find My, protect your Apple Account with two-factor authentication and check app permissions regularly. macOS already includes Gatekeeper and XProtect as built-in protection mechanisms against malware.
Do these security settings apply to MacBook, Mac mini, Mac Studio and iMac?
Yes. Most security settings are part of macOS and therefore generally apply to MacBook Air, MacBook Pro, Mac mini, Mac Studio and iMac. Individual menu items or features may differ slightly depending on the model, year, processor and installed macOS version.
On a mobile MacBook Air or MacBook Pro, theft protection, Find My, FileVault and quickly locking the screen play a particularly important role. On a desktop Mac mini, Mac Studio or iMac, also keep an eye on network access, user accounts and the firewall.
1. Automatically keep macOS and security updates current
One of the most important security measures is also one of the simplest: install macOS updates promptly. This applies to MacBook Pro and MacBook Air just as much as to Mac mini, Mac Studio and iMac. Apple closes security vulnerabilities and updates important system components through updates.
Open System Settings → General → Software Update and check automatic update settings. Current macOS versions also include background security improvements. These can provide important security fixes between major software updates.
2. Enable FileVault on MacBook, Mac mini, Mac Studio and iMac
FileVault protects the data on your startup disk. On Macs with Apple silicon or a T2 Security Chip, data is already encrypted with hardware support; FileVault adds to this protection by requiring authentication to access the data.
This is particularly important on a mobile MacBook Air or MacBook Pro because a laptop can be lost or stolen more easily. But a Mac mini, Mac Studio or iMac can also contain confidential documents, photos, login details or business files.
Find the setting under System Settings → Privacy & Security → FileVault.
The recovery method is particularly important. If you use a recovery key, keep it securely and separately from the Mac. Without a login password or a working recovery method, encrypted data may be inaccessible in an emergency.
3. Enable Find My and Activation Lock
If a MacBook Air or MacBook Pro is lost or stolen while travelling, Find My is one of the most valuable features. However, it is not only interesting for MacBooks: you should also correctly configure supported desktop Macs such as Mac mini, Mac Studio and iMac with your Apple Account and Find My.
You can then locate a supported Mac and take further protective measures. If you enable Find My Mac and the requirements are met, Activation Lock is enabled too.
Check under System Settings → Your name → iCloud → Find My Mac that the feature is enabled. The relevant Location Services must also be allowed for locating the device.
4. Use two-factor authentication for your Apple Account
Your Apple Account particularly deserves protection because it can provide access to iCloud data and device features, among other things. This is independent of whether you use an iMac at home, a Mac mini in the office or a MacBook Pro on the go. Two-factor authentication adds a second security layer to your password.
Check this under System Settings → Your name → Sign-In & Security. If two-factor authentication is already enabled, also check that your trusted phone numbers and devices are still current.
5. Use a strong Mac login password
Touch ID makes signing in convenient on suitably equipped Macs, but does not diminish the importance of a good login password. Do not use a password you also use for online services, and avoid easily guessed words, names or number sequences.
If several people use the same iMac, Mac mini or Mac Studio, it is better to create a separate user account for each person rather than sharing one account. Naturally, the same applies to shared MacBooks.
6. Automatically lock MacBook Air and MacBook Pro
A well-protected Mac is of little use if it is left unlocked on a desk. Configure it to require a password promptly after the screen saver starts or the display turns off.
This is particularly important with a MacBook Air or MacBook Pro used at university, on a train, in an office or in a coworking space. However, a desktop iMac, Mac mini or Mac Studio should also lock automatically if other people have access to the workspace.
7. Regularly check app permissions
macOS lets you specify in great detail which apps can access sensitive areas. Open System Settings → Privacy & Security and review permissions occasionally. These settings apply equally on MacBook Pro, MacBook Air, Mac mini, Mac Studio and iMac.
Only allow apps that genuinely need it.
Remove old or unknown permissions.
Grant access to personal data deliberately.
Particularly sensitive for remote support and meeting apps.
Only enable where location data makes sense.
Check which apps have extensive control permissions.
An app you deleted long ago or hardly use normally no longer needs extensive access permissions either.
8. Check the firewall on Mac mini, Mac Studio, iMac and MacBook
The firewall built into macOS can block unwanted incoming network connections. Find it under System Settings → Network → Firewall.
On a desktop Mac mini, Mac Studio or iMac that runs permanently on a home or business network, checking network sharing is particularly worthwhile. With a MacBook Air or MacBook Pro, also take care if you frequently use unfamiliar or public networks.
Firewall options let you specify which apps and services may receive incoming connections. If you want particularly restrictive network behaviour, also look at stealth mode.
Important: a firewall does not replace updates, secure passwords or protection against malware. It is an additional layer of protection.
9. Only install apps from trusted sources
macOS uses features including Gatekeeper to limit the execution of untrusted software. Apps outside the Mac App Store can be entirely legitimate, but you should know exactly where they come from.
Do not simply bypass security warnings because a downloaded app asks you to in its installation instructions. Download programs directly from the manufacturer or Mac App Store where possible, and keep installed apps up to date as well. This applies to powerful work devices such as Mac Studio and MacBook Pro just as much as to Mac mini, iMac and MacBook Air.
10. Do MacBook Pro, MacBook Air, Mac mini or iMac need an antivirus scanner?
macOS already includes several built-in protection mechanisms. These include Gatekeeper, Apple’s software notarisation and XProtect. XProtect is Apple’s built-in technology for detecting and removing known malware, and automatically receives new security information.
These protection mechanisms are part of macOS. The basic answer therefore does not differ depending on whether you use a Mac mini, Mac Studio, iMac, MacBook Air or MacBook Pro.
For many private users, an additional antivirus scanner is therefore not strictly necessary if the system is kept up to date, software comes from trusted sources and security warnings are taken seriously.
Additional security software can still make sense, for example in businesses with mandatory security policies, specific compliance requirements or a need for centrally managed endpoint protection.
11. Use passwords and passkeys sensibly
Use different passwords for different services. A password manager avoids the need to remember dozens of complex passwords. Where available, passkeys are also an interesting alternative to conventional password-based sign-in.
Particularly important: the password for your Apple Account and the password for your primary email address should be unique. Someone with access to your email account can initiate password resets for many services.
12. Use Time Machine for MacBook, Mac mini, Mac Studio and iMac
Security is not just protection against other people’s access. A hardware fault, accidental deletion or software problem can also endanger data. A current backup is therefore part of every sensible Mac configuration.
Time Machine is suitable for backing up a MacBook Air, MacBook Pro, Mac mini, Mac Studio or iMac. We explain how to set it up and which storage media are suitable in detail in our guide Back up your Mac properly: Time Machine backups explained.
MacBook Air or MacBook Pro stolen – What should you do?
The risk of loss is naturally higher for mobile devices. If Find My was configured before the loss, you can look for your MacBook Air or MacBook Pro through the Find My app on another Apple device or Apple’s web service and use available protection features. Depending on the situation, you can mark the device as lost or erase it remotely, for example.
The same Find My features can also be relevant for a stolen supported Mac mini, Mac Studio or iMac.
Do not remove a stolen Mac from Find My too quickly. Activation Lock is an important part of theft protection and is intended to prevent the device from simply being reactivated without your permission.
