To download Google Chrome for a Mac with the specifications you've mentioned (Mac OS 10.15.7), follow these steps. Ensure your Mac meets the system requirements for the version of Chrome you are trying to install.

Official "Other Platforms" Menu: Visit the Google Chrome Download Page, scroll to the very bottom, and select "Other Platforms". Look for the "Frozen Version" or specifically for macOS 10.15.

1. A build number or internal Chrome revision (Chrome’s major versions are in the 100+ range, e.g., 124, 125, etc.).
2. A typo (e.g., someone meant 115.0.5790.170, etc.).
3. A malicious trick – cybercriminals sometimes use fake version numbers to lure users into downloading malware disguised as Chrome.

Drag to Applications: A window will appear. Click and drag the Google Chrome icon into the Applications folder shortcut within that same window.
