Apple has released OS X Yosemite Public Beta 6 to users for testing. The build number is 14A388b.
Just a few days ago, Apple released the OS X Yosemite GM Candidate 3.0 to developers for testing. The company is expected to launch its new operating system at a special event on October 16th.
I installed it last night.
MacBook Pro (15-Inch, Early-2011)
8GB Ram
500GB Hard Disk
Three issues:
1. The install process arbitrarily deleted directories in my postgres installation (via homebrew). I had to reinstall to correct it.
2. Chrome helper processes are not reporting properly to Activity Monitor. They all report "Not Responding". But there's actually nothing wrong with them.
3. Certain vendors, it seems, have pegged their major release licenses to OS X releases. So, if you use Mailplane 2, or VMWare 6, or a few other pieces of software, be prepared for an expensive surprise.
The public betas are basically just the developer previews except those in the public beta receive the updates later. There have been three GM candidates released so far for the developers. The 6th public beta is simply the catch-up update for the public.
In other words, the 6th public beta is the third GM candidate, released slightly later for the public.
Hope that clarifies everything.
