13. You should do software updates
Although Apple may be releasing Yosemite updates to beta testers on a different timeline than the one it follows for offering preview releases to developers, the company will almost certainly issue updates during the beta period. You should look for and install these updates, because they will fix known bugs and will likely introduce new features along the way. Once the final build of Yosemite is released, you'll be able to upgrade to it.
The final word: Have fun
A large part of what I've said focuses on the potential pitfalls and problems you could run into while beta-testing Yosemite, along with ways to minimize their impact. You should keep those things in mind, but you should also enjoy testing Apple's latest OS X release. If Apple adheres to its public time frame, we might not be able to do this again until 2028.
Apple is releasing its first public beta of OS X Yosemite. Is that a smart move?
