Baffled to why anyone would prefer either Firefox or Chrome over Safari.
Safari is crap, that's why. It often does not render sites properly and is slow on many others. I use Vivaldi. Like Edge, it is based on Chromium. It doesn't spy on you and gives you a lot of control over cookies and other items pertaining to your personal security. True, it takes up a lot of resources when you use extensions such as Google Translate, Dark Reader, Adblock, etc. but it's feature set blows Safari out of the water, especially the ability to tile stacked tabs. Dark Reader is by far one of the best extensions to render web pages in dark mode and I think it's very telling that Safari's free Dark Mode extension does a crap job with web pages, Facebook in particular, but they charge for the Dark Reader extension in the App store!
The Safari UI is a disaster and always has been. I've tried it several times and never could get used to its tab sizes. I also detest how Safari is tied to both MacOS and iOS 13 without giving the user the choice to switch OS features to another browser which is hilarious considering that Apple was one of Microsoft's biggest critics, touting the Mac's "freedom" and joining the industry in demanding Microsoft remove Windows' ties to Internet Explorer 20 years ago. Now they're doing the same thing.
The latest Vivaldi snapshot is 2.7 RC 1 and it's awesome.
[doublepost=1566322245][/doublepost]Does anyone have any temperature or fan speed issues? I experienced a LOT of high temps (and high fan speeds to compensate) in Beta 5 and had to run iStat's fan rules for the first time ever. In Beta 6, the Mac is running a lot cooler. However, and I'm still experiencing insane fans speeds running a VM in Parallels - a behavior that I simply don't recall in Mojave. I stress that these are high fan speeds NOT associated with high CPU or higher temps and again, only with Parallels.
I've been running the latest public Apple TV beta but have not updated to the next available version yet. Home Sharing to the Apple TV, which was broken in B1 - 3, worked in B4, but was broken in B5, still seems to be broken in B6. If it works after I update the Apple TV, I'll edit this post. It works great, however, in iOS 13's Apple TV app.
