This is the most common consumer reason. A 2009 iMac or a 2011 MacBook Air cannot run modern Chrome (which often consumes 2GB+ of RAM for three tabs). Users seek Chrome 49 or 58—the last versions to support older OSes like Mac OS X Snow Leopard (10.6) or Mountain Lion (10.8)—to breathe life into obsolete hardware. The Great OS Divide: Compatibility Charts You cannot simply download "Chrome 70" and run it on macOS Sonoma. Apple breaks binary compatibility regularly. Here is the rough timeline of Chrome versions tied to macOS releases:
Digital investigators sometimes need to render a webpage exactly as it appeared in 2018. Using an archived version of Chrome from that era, paired with a specific OS build, ensures that layout engines (Blink) and JavaScript interpreters (V8) render the site authentically, unaltered by modern security patches. google chrome old versions mac
The shift from Manifest V2 to Manifest V3 (which began phasing out in 2022 and concludes in 2024-2025) crippled many ad-blockers like uBlock Origin.

Instead, use: OmahaProxy – A community tool that scans Google’s update servers (Omaha) to generate direct download links for every official Chrome release since version 1.0. 2.
