Make your bootable backup before upgrading Early adopters inevitably find some shortcomings and bugs which are resolved in minor OS updates. The early releases are exciting, but that excitement involves risk. Lastly, we recommend that any users that rely heavily upon the availability of their Mac for work or other productivity consider waiting for several OS updates before making a major upgrade. These sorts of procedures require time and effort, though, so you should weigh that potential hassle against the potential gain of the OS upgrade.

Major system upgrades are often disruptive, so we have always recommended a very conservative approach to applying them. Unless, that is, you have a complete, bootable backup of your Mac made before you upgrade. If you upgrade your OS only to discover that a critical third-party application or peripheral doesn't work right, you could be really lost when you discover that it's impossible to downgrade to a previous OS.

So Apple has shipped the next major operating system, and you're excited to upgrade! But are you ready? OS upgrades offer the thrill of new features, better performance and bug fixes, but they can come at a price - your time and potentially your productivity.
