Every Mac accumulates a significant amount of user data aimed at enhancing macOS and Apple applications. A fair portion of this data gathering occurs automatically, so it is worthwhile to understand what is being collected. Apple provides transparent information regarding its data collection practices, which is generally accessible and easy to understand. Furthermore, a majority of the data collected undergoes encryption, rendering it unreadable to Apple itself. Nonetheless, it is essential to have data collection configured as an opt-in feature rather than a default setting. The following guide will assist in examining your Mac’s data collection preferences and employing external tools to minimize unnecessary communication from your computer.

On the topic of privacy, consider taking steps to opt-out of tracking by data brokers and restricting data collection on your iPhone.

Implement a Third-Party Firewall

While Apple’s built-in firewall provides some level of protection, it is not sufficient for monitoring Apple’s own data collection activities. Third-party solutions work effectively on macOS, offering more flexibility than iOS allows. Applications such as Little Snitch ($63), Radio Silence ($9), and the free LuLu can be employed to track outgoing communications from apps and services. Utilizing a robust firewall, it becomes possible to block any outbound connections—including those initiated by Apple—therefore reducing potential tracking.

While some connections for automatic software updates are essential, many outbound requests may not be necessary at all. Use your firewall to monitor and restrict these unnecessary communications.

Disable Apple Intelligence Features

Although Apple Intelligence has its merits, it may inadvertently slow down devices like the M1 MacBook Air and necessitates data transmission to Apple’s servers. Even if data is encrypted, the reliance on cloud services for AI functionalities could be a concern. To manage these settings, navigate to the Apple logo in the top-left corner and select System Settings > Apple Intelligence & Siri to turn off Apple Intelligence.

Minimize Siri’s Data Gathering

Following the Siri data collection settlement, it is advisable to exercise caution regarding the information collected through Apple’s voice assistant. Apple has become increasingly transparent about the data processing for Siri, which can be reviewed by accessing System Settings > Apple Intelligence & Siri. By selecting About Siri, Dictation & Privacy, one can see that Siri’s transcripts are indeed recorded. This aspect of data collection can be avoided by disabling Siri and dictation. On the Siri settings page, opt for Delete Siri & Dictation History and confirm by clicking Delete. Lastly, make sure to switch off Siri and turn off Dictation in System Settings > Keyboard to finalize the adjustments.

Turn Off Apple Analytics

A substantial amount of data regarding app crashes, bugs, and usage patterns is gathered by Apple while a Mac is in operation to improve features and identify priorities. Although this information is anonymized before sharing, you hold the power to review and control its sharing. To manage these settings, navigate to System Settings > Privacy & Security > Analytics & Improvements and explore the various options. Disabling all features listed on this page is recommended.

Review Apple’s Location Access

For the most part, denying location access to applications on a Mac is advisable. Nonetheless, discovering that system apps have enabled location access can be surprising. By going to System Settings > Privacy & Security > Location Services and clicking the Details button next to System Services, you can inspect which applications have been granted location permissions. Disable access for non-essential services while keeping it enabled for critical services such as Find My. Consider disabling access for Mac Analytics and a few others.

Additionally, by clicking the Details button next to Significant Locations, you can check the location history collected by Apple regarding your frequent locales. You can choose to delete this data and revoke future access. Keep in mind that this information is encrypted and cannot be accessed by Apple, as it claims to use it for enhancing features in Photos, Maps, Calendar, and other system applications.

Limit Personalized Advertising

In recent years, Apple has significantly promoted its own advertising, particularly within the Mac ecosystem. While the situation is less pervasive compared to iOS, seeing ads in the Mac App Store can still be bothersome. Though complete ad blocking isn’t feasible, you can navigate to System Settings > Privacy & Security > Apple Advertising to disable Personalized Ads.

Exploring iCloud Alternatives on Mac

To thoroughly assess Apple’s data collection practices, iCloud also merits attention. While iOS heavily relies on iCloud for efficient data synchronization and backups, macOS is more flexible, making iCloud less crucial. Many built-in applications like Apple Notes, Messages, Calendar, and Reminders do require iCloud, but alternative services are available for other backup needs.

It’s vital to recognize that opting for cloud storage can expose your data to collection. It becomes necessary to weigh the benefits of allowing Apple access against those of alternative providers. Many users prefer diversifying their data storage solutions, while others may lean towards a singular service. Fortunately, dedicated online backup services like Backblaze ($99/year) are available for Mac users, a function not possible on iOS. Offline backups using Time Machine or third-party software such as Carbon Copy Cloner ($40) also facilitate reduced dependence on iCloud.
