macOS Sequoia

Basic Information

Apple macOS Sequoia (version 15) is the twenty-first major release of Apple's macOS operating system, succeeding macOS Sonoma. It was announced at WWDC 2024 on June 10, 2024, and became generally available on September 16, 2024. The latest stable version is 15.7.2, released on November 3, 2025. macOS Sequoia is proprietary software, incorporating open-source components and content licensed under the Apple Public Source License (APSL).

The operating system is deployed primarily preinstalled on Apple-branded hardware. Enterprise deployment leverages Mobile Device Management (MDM) solutions, Apple Business Manager, and Apple School Manager, supporting features like account-driven device enrollment and declarative device management. Users can install one copy on a single Apple-branded computer, with volume or maintenance licenses available for multiple copies.

Apple typically provides security updates for the latest three macOS releases. macOS Sequoia is expected to receive support until approximately January 27, 2028. Its successor, macOS Tahoe, was released on September 15, 2025. Automatic software updates are enabled by default, but users retain control over these settings.

Technical Requirements

• Processor: Apple silicon (M1, M2, M3, or later) or Intel-based Macs with Skylake-based Xeon W and 8th-generation Coffee Lake chips or later.
• RAM: A minimum of 8 GB is recommended for smooth operation.
• Storage: At least 12-15 GB of free disk space is required for installation, with a recommendation of 25-49 GB of free space to maintain optimal performance.

User Reviews & Feedback

User reviews and feedback for macOS Sequoia generally highlight its strengths in productivity, creativity, and seamless integration within the Apple ecosystem.

Strengths

Users appreciate the enhanced continuity features, such as Universal Clipboard 2.0 and improved FaceTime Hand-Off, which facilitate smooth transitions between Apple devices. The revamped Finder with natural language search capabilities and new privacy features are also well-received. Apple Intelligence, with its Writing Tools, Image Playground, Genmoji, enhanced Siri, and ChatGPT integration, is a significant draw for many, offering powerful new ways to communicate and create. iPhone Mirroring, allowing full interaction with an iPhone from a Mac, is seen as a highly convenient feature. Improvements to window tiling and an updated Safari browser further enhance the user experience.

Weaknesses

A notable limitation is that many of the advanced Apple Intelligence features are exclusive to Macs equipped with Apple silicon (M1 chip or later), leaving Intel Mac users without access to these capabilities. The discontinuation of support for certain older Intel Macs, specifically the 2018 and 2019 MacBook Air models, has also been a point of concern for some users. Additionally, iPhone Mirroring is not available in the European Union due to Digital Markets Act (DMA) regulations. Some users express caution regarding automatic updates, preferring manual control over system upgrades.

Recommended Use Cases

macOS Sequoia is recommended for users prioritizing productivity, creative workflows, and a deeply integrated multi-device experience within the Apple ecosystem. Its robust security and privacy features make it suitable for individuals and enterprises alike. Enterprise environments benefit from its advanced MDM capabilities for streamlined device management and enhanced security postures.

Summary

Apple macOS Sequoia (version 15) represents a significant evolution in Apple's operating system, focusing on enhanced productivity, creativity, and deeper integration across its device ecosystem. Released on September 16, 2024, it brings a suite of new features, most notably Apple Intelligence, which leverages on-device machine learning for personalized and context-aware experiences. This includes advanced writing tools, image generation capabilities, and an enhanced Siri. Another key feature is iPhone Mirroring, allowing seamless interaction with an iPhone directly from a Mac.

The operating system is compatible with a range of recent Macs, including those with Apple silicon (M1, M2, M3, or later) and specific Intel-based models from 2017 onwards. However, the full suite of Apple Intelligence features is exclusive to Apple silicon Macs, marking a clear advantage for newer hardware. macOS Sequoia requires a minimum of 8 GB RAM and a substantial amount of free storage for installation and optimal performance.

From a security standpoint, Sequoia continues Apple's commitment to user privacy and data protection. It introduces features like Sensitive Data Isolation, an encrypted Passwords app, and robust enterprise-grade security enhancements, with regular updates addressing vulnerabilities. The system is praised for its stability and seamless performance, particularly on optimized Apple hardware.

While user feedback is largely positive regarding new features and overall stability, some users note the exclusion of older Intel Macs from support and the regional unavailability of certain features like iPhone Mirroring in the EU. The operating system is well-localized, supporting numerous languages.

In summary, macOS Sequoia is a powerful and secure operating system, best suited for users with modern Apple hardware who can fully leverage its advanced features, especially Apple Intelligence. Its strengths lie in its integrated ecosystem experience, robust security, and productivity enhancements. The primary weakness is the hardware dependency for its most innovative features, potentially segmenting the user base.
