How to Update & Upgrade
| Info |
|---|
Update vs. Upgrade, what’s the difference? Updates are minor changes to the current major OS version to improve security, fix bugs, and enhance features. They’re smaller making them quicker to install and are also more frequent. For example, updating from macOS 14.7.1 to macOS 14.7.2. It’s like getting a tune-up for your car. Upgrades are to go from one major OS version to another, with significant changes that typically include new features, changes to the interface, and major performance enhancements. They take longer because the current version of the OS is being replaced with the new one. For example. upgrade from macOS Sonoma 14 to macOS Sequoia 15. It’s like trading in your car for the new model. |
Update & Upgrade Prompts from CNS OIT

Reminders from Nudge
