As technology marches forward, older systems inevitably get left behind—and Google Chrome is no exception. The Chrome Platform Status blog has officially confirmed that Chrome 150 will be the last version compatible with macOS 12 Monterey, signaling a major change for Mac users who haven’t upgraded their operating system. This update isn’t just about missing out on new features—it directly impacts your browser’s security, performance, and overall usability. For millions still using macOS 12, it’s a wake-up call: stay on an unsupported system and you risk falling behind on critical updates.
the Original
Google has announced that Chrome 150 will be the final release to support macOS 12 Monterey. From Chrome 151 onward, Macs running this version of macOS will no longer be supported. Users on macOS 12 will still be able to run Chrome 150, but the browser will display a warning infobar notifying them that no further updates will be provided.
This means that these users will miss out on all future security patches, bug fixes, performance improvements, and new features. Since running a supported operating system is crucial for safe browsing, staying on macOS 12 could leave users exposed to vulnerabilities.
Google hasn’t given a precise timeline for when Chrome 151 will launch, but with Chrome typically releasing a major update every four weeks and the current stable version at 143, Chrome 151 is expected around mid-to-late August this year. Users still on macOS 12 are advised to either upgrade to macOS 13 Ventura or later or consider switching to an alternative browser to stay secure.
Additionally, the original article briefly mentioned Amazon accessory deals, including Apple AirTags, AirPods Pro 3, Beats cables, and other tech peripherals, which are tangential to the Chrome news.
What Undercode Says:
Security Risks of Staying on macOS 12
Continuing to use Chrome on macOS 12 beyond version 150 will significantly increase security risks. With no security patches, users could become targets for malware, phishing attacks, or other vulnerabilities that are patched in later versions of Chrome. Cybersecurity experts strongly recommend staying on a supported OS for all applications, not just browsers.
Performance and Feature Limitations
Even if Chrome 150 continues to run, users will miss out on performance enhancements and new features. Modern Chrome updates often include optimizations that reduce memory usage, improve battery efficiency, and add features like new developer tools or AI-powered functionalities. Staying on an outdated version can slow down everyday browsing and create compatibility issues with modern websites.
Upgrade Path Considerations
Mac users on macOS 12 have two main options: upgrade to macOS 13 Ventura or later, or switch to a different browser that still supports macOS 12. Upgrading the OS ensures continued Chrome support and access to Apple’s security updates, whereas switching browsers may solve the immediate compatibility issue but could create a fragmented experience across devices.
Timeline and Planning
Assuming the typical Chrome update cycle, version 151 will likely roll out in mid-to-late August 2026, giving users around seven months to prepare. This window provides time to back up important files, test hardware compatibility, and plan a smooth transition to either macOS 13 or another browser solution.
Broader Implications
This move is part of a wider trend where software developers increasingly drop support for older operating systems. With Apple phasing out updates for macOS 12, Google is following a standard industry practice. Users should see this as a reminder to maintain their devices proactively and avoid falling behind technologically.
User Awareness and Behavior
Many users stick with older OS versions for stability or software compatibility, but this decision comes with trade-offs. The Chrome 150 cutoff emphasizes the need to balance stability with security and functionality, especially for those who use their Macs for work or sensitive information.
Tech Ecosystem and Competition
This change could benefit other browsers that still support macOS 12, such as Firefox or Safari on older systems, temporarily increasing their user base. However, these browsers may also follow a similar phase-out path, reinforcing the importance of OS updates for long-term security.
Practical Advice for Users
Before mid-to-late August, macOS 12 users should:
Review device compatibility with macOS 13 or later
Backup all critical data
Evaluate alternative browsers if upgrading is not feasible
Prepare for potential security and performance issues if staying on macOS 12
Final Thoughts
While some users may initially resist upgrading, the risks of remaining on an unsupported OS far outweigh the convenience of staying put. Chrome’s phase-out of macOS 12 is a clear signal: modern browsing requires modern systems.
🔍 Fact Checker Results
✅ Chrome 150 will be the last version supporting macOS 12 Monterey – Verified.
✅ Chrome 151+ will not receive updates on macOS 12 – Verified.
❌ No official date for Chrome 151 release has been announced – Correctly noted as an estimate.
📊 Prediction
By August 2026, a significant portion of macOS 12 users will either upgrade to macOS 13 or switch browsers, driven by the need for security and modern features. Some may explore alternatives like Firefox or Edge temporarily, but long-term reliance on an unsupported OS will likely decline sharply. Mac hardware that is incompatible with macOS 13 may see decreased Chrome adoption and slower web performance, nudging users toward device upgrades sooner than planned.
