If it's anything like past releases then you can do what most of us Appleseed members have done for years; install the beta on a different partition of the same internal drive. It doesn't impact your "production" partition (make sure to keep that backed up properly) and allows you to play/test the new OS when you have time (a simple reboot to switch between the two OSes).
Did it with 10.6 through 10.9 betas and never had any issues. The more people that test and provide feedback the better. Cheers.
Do you disable Spotlight on the 'beta' partition? I don't want double entries in the Spotlight window for system apps (for example, Maps on both Mavericks and Yosemite would appear as two entries on a Spotlight search).
Signed up
I am wondering how long it will take for the million![]()
I signed up. I may put it on an external SSD and run it from there. I don't want to mess with my regular setup on a beta.
