I hope this fixes the issue where the email log files are in the 4-24GB range if you leave mail open. I was also having an issues where safari would auto correct along the way and then revert all of the corrections if I used backspace at any time.
Got a tip for us?

No, that isn't how Apple labels their betas. Security updates get rolled into betas as they progress.

I thought betas and GMs are versioned? There was a Yosemite GM 1.0 and 2.0, and there have been 2.0 versions of beta releases, I think? In App Store, each beta used to be labeled 1.0. However, looking at the beta 5, it reads, "Version 5.0" whereas previously betas were labeled 1.0, so maybe I formed a mistaken impression based on that.
Thanks, I used your link to the direct download. I'm a registered developer, but it was not showing up in my App Store updates, and the link on the Apple Developer site was for a code I already redeemed. The link worked great, and got it all installed. Thanks!
If only there was a toggle switch for turning "Mouse cursor locator" on and off 
Well, yes and no. Other system components using Metal means that more resources are freed up for applications to use, which is likely where you're feeling a performance improvement, even if those apps don't use metal.
Your source on this? AFAIK, OpenGL and Metal are completely independent frameworks at this point. Also, OpenGL is more full-featured than Metal, so implementing it on top of Metal right now is it not feasible.
Actually.... Blizzard is backing Vulkan... and I highly suspect that Metal is built on much of Vulkan.
No... because the gaming industry is looking for standard API's. It makes it immensely easier to use the same API for every platform. By Apple creating their own graphics API they've just guaranteed that less game developers will jump on their platform... because every different API requires programmers who know that API. Which means it costs more money not only to implement, but also to support. And if you knew anything about Mantel (now becoming Vulkan), you'd understand just how silly your comment sounds.
Blizzards logo was among those displayed during the keynote when they talked about Metal. And on blizzard forums there has been blue posts (Blizzard employees) confirming they are bringing Metal to their games. The Mac client for all their games is separate from the PC. Built for Mac and not just a direct port. So yes they are also backing Metal and not just Vulcan.
Entities that are throwing their weight behind Vulkan: AMD, Nvidia, Sony (for PS4), Lucasfilm, Qualcomm, Samsung, Pixar, Epic Games, Steam, Apple, Unity, Continental, Oculus VR, Valve, Oxide, Intel, ARM, Vivante, Mobica, codeplay, Blizzard, Electronic Arts, Mediatek, Transgaming, Riot Games, and lots of other smaller entities. This isn't a fly-by-night API. This is meant to be a modern API to ultimately replace OpenGL... and it operates on existing hardware that can runOpenGL 2.1 or higher.
Perhaps Blizzard (and others) will be supporting both Metal and Vulkan?
They are. Here is an image from the keynote.

You do understand the meaning of "beta software" don't you? If not, you should read this.
Last paragraph: "Since beta software is a pre-release version of the final application, it may be unstable or lack features that will be be included in the final release. Therefore, beta software often comes with a disclaimer that testers should use the software at their own risk. If you choose to beta test a program, be aware that it may not function as expected."
No it doesn't. Please, have you even looked at the preliminary API specs? What we saw of Vulkan so far is essentially AMD's Mantle plus some bits of Metal concepts. But Metal is vastly different in the way resource are bound to shaders for instance.
I think your analysis is wrong. What the gaming industry is looking for is not standard APIs but reliable, easy to work with APIs that come with performance guarantees. Standardisation is only needed in the shading language, this is why I really hope that Apple will pick up SPIR-V. For a game developer, it is cheaper to implement three renderer backbones in three different APIs than to debug idiosyncratic behaviour in a single bloated API such as the modern OpenGL. Not to mention that most developers use ready-made engines so they don't even need to care which API is used. As to the 'programmers need to know the API'... once you understand how one graphical API works, it takes literally few hours to learn another one. Besides, modern graphical APIs are so straightforward (not to mention similar) that a developer who can't learn them is simply not competent enough to land a job. All these teams reporting that it took them a week to port their code to Vulkan/Metal are not exaggerating. Its really that easy. Again, the trickiest bit is the shading language.
Now, there are obvious benefits to having unified API for all the platforms. On the other side, Apple wanted some improvement now, they already had a very nice API (which is btw much programmer-friendly than Mantle/Vulkan) and the status of Vulkan is unclear at this point. It made sense for Apple to release their own API first. I can imagine that next year, when Vulkan API is finalised, Apple might extend Metal with Mantle-like descriptor sets and then implement Vulkan as a wrapper around Metal. It would probably make the most sense in the long run.
I really wonder how much you know based on what you write
