waiting since long- whens the public beta coming out?

[kayleee]

when is it coming out? any dates you guys know of?

Also, do you guys recommend I install the beta on the main drive, or do it on a partition?

Public beta will be release in July. It would be best to install on a separate partition.

If you only have 1 Mac I don't recommend installing beta OS because it will very likely be buggy. At the very least make a clone with Disk Utility or other such software and install it on a external drive.
