How to Install new macOS Beta Safely on Separate Partition & High Sierra Performance Tests

In this video we'll be guiding you how to setup the latest macOS High Sierra beta. We'll be doing it on a separate partition which means you can still use your current version of macOS on the same computer, keeping you safe. But, also showing you how you can still access all the apps and documents from your current macOS from the new macOS High Sierra.

Unboxing the Apple External Graphics DevKit:

First up we're going to create a small partition to install macOS High Sierra on. Now High Sierra takes up around 10GB, so you don't need to allocate much space for it. Partitioning takes around 5 minutes, with this video being sped up.

Second, you'll need to download the beta, you can do this by heading on to either the or the websites. Which will unlock the app in the App Store app for download.

Third, just launch the installer, but remember to select the new partition we just created to ensure you can still use your current macOS.

Fourth, wait around 20 minutes for the Mac to reset itself a few times.

Next, you just go through the standard setup procedure.

The beta has analytics and diagnostics reporting enabled by default, you can always disable this from the privacy option in System Preferences.

Now, we're going to enable access to your current version of macOS from High Sierra. To do this you need to head on to Disk Utility and unlock your main partition. If you've encrypted your drive using FileVault, you'll be prompted to input the encryption password for access.

Once that's done, in my experience I needed to restart my Mac to actually be able to access the drive.

All your apps and documents are now available to you in the new OS, just head to the Applications folder in your main partition and launch. If you haven't restored from a backup, all your app specific settings will need to be re-configured. If you do TimeMachine backup your mac, all will be good in the world.

To switch between High Sierra and Sierra, you can do this from either the Startup Disk option in System Preferences. Or when resetting your Mac, hold the alt key and select the partition to boot with.

Of course this is still a beta version of the operating system, so performance will improve, but for now I find that exporting a video using Final Cut Pro is around 10% slower in High Sierra when compared to Sierra.

Random YouTube Video Generator

 This site provides links to random videos hosted at YouTube, with the emphasis on random.

 The original idea for this site actually stemmed from another idea to provide a way of benchmarking the popularity of a video against the general population of YouTube videos. There are probably sites that do this by now, but there wasn’t when we started out. Anyway, in order to figure out how popular any one video is, you need a pretty large sample of videos to rank it against. The challenge is that the sample needs to be very random in order to properly rank a video and YouTube doesn’t appear to provide a way to obtain large numbers of random video IDs.

 Even if you search on YouTube for a random string, the set of results that will be returned will still be based on popularity, so if you’re using this approach to build up your sample, you’re already in trouble. It turns out there is a multitude of ways in which the YouTube search function makes it very difficult to retrieve truly random results.

 So how can we provide truly random links to YouTube videos? It turns out that the YouTube programming interface (API) provides additional functions that allow the discovery of videos which, with the right approach, are much more random. Using a number of tricks, combined some subtle manipulation of the space-time fabric, we have managed to create a process that yields something very close to 100% random links to YouTube videos.

 YouTube is an American video-sharing website headquartered in San Bruno, California. YouTube allows users to upload, view, rate, share, add to playlists, report, comment on videos, and subscribe to other users. It offers a wide variety of user-generated and corporate media videos. Available content includes video clips, TV show clips, music videos, short and documentary films, audio recordings, movie trailers, live streams, and other content such as video blogging, short original videos, and educational videos. Most content on YouTube is uploaded by individuals, but media corporations including CBS, the BBC, Vevo, and Hulu offer some of their material via YouTube as part of the YouTube partnership program. Unregistered users can only watch videos on the site, while registered users are permitted to upload an unlimited number of videos and add comments to videos. Videos deemed potentially inappropriate are available only to registered users affirming themselves to be at least 18 years old.

 YouTube and selected creators earn advertising revenue from Google AdSense, a program which targets ads according to site content and audience. The vast majority of its videos are free to view, but there are exceptions, including subscription-based premium channels, film rentals, as well as YouTube Music and YouTube Premium, subscription services respectively offering premium and ad-free music streaming, and ad-free access to all content, including exclusive content commissioned from notable personalities. As of February 2017, there were more than 400 hours of content uploaded to YouTube each minute, and one billion hours of content being watched on YouTube every day. As of August 2018, the website is ranked as the second-most popular site in the world, according to Alexa Internet, just behind Google. As of May 2019, more than 500 hours of video content are uploaded to YouTube every minute.

 YouTube has faced criticism over aspects of its operations, including its handling of copyrighted content contained within uploaded videos, its recommendation algorithms perpetuating videos that promote conspiracy theories and falsehoods, hosting videos ostensibly targeting children but containing violent and/or sexually suggestive content involving popular characters, videos of minors attracting pedophilic activities in their comment sections, and fluctuating policies on the types of content that is eligible to be monetized with advertising.
