Upgrade vs. Update

This terminology can be confusing. At ÈËÆÞÓÕ»ó, upgrade and update are defined in the following way.

Upgrading your operating system is a "major version" jump. Moving from Windows 10 to 11, or macOS Sequoia (15.7) to macOS Tahoe (26.5) would be an operating system upgrade.  Your system is likely to look and feel different after an OS upgrade. When it is confirmed to be compatible with ÈËÆÞÓÕ»ó's environment, ÈËÆÞÓÕ»ó provides guidance on upgrading to the latest version of macOS.

Updating your system applies patches and fixes to the currently installed OS. These updates patch important security vulnerabilities. For example, moving from macOS 26.0 to 26.5.1 is classified as an OS update. Sometimes these updates are not obvious or not listed in the Software Update window, but are hidden under "Other updates are available - More info..."
