Setting up ESXi for running Apple Mac OS X Vmware ESXi 6.0 doesn’t support OS X out of the box. So, the first thing you need to do is to customise the hypervisor layer by executing an Unlocker. BeOS is an operating system for personal computers first developed by Be Inc. It was first written to run on BeBox hardware. BeOS was positioned as a multimedia platform that could be used by a substantial population of desktop users and a competitor to Classic Mac OS and Microsoft Windows.

We all know by now that macOS Big Sur is the latest and greatest version of Apple’s Mac operating system. It was released in November 2020 and offered some serious advancements, especially on the visual side. If you have an older machine, though, you may be wondering whether your Mac is compatible. Let’s shed some light on macOS Big Sur system requirements and help you check whether your Mac supports the new OS.

Before you attempt to upgrade to Big Sur

There are a couple of things you should do before you upgrade to Big Sur.

  • Back up your Mac.

It doesn’t matter whether you use Time Machine or a third-party backup tool, just make sure you backup your Mac immediately before you upgrade.

  • Free up some space for the new OS

To get macOS Big Sur running on your Mac, you need at least 20GB of free space. So, if you aren’t sure you have enough, here’s how to check it. Click the Apple menu and select About This Mac. Go to the Storage tab to let your Mac calculate the amount of free space. If you don’t have enough, you can try removing some old junk with CleanMyMac X. This app detects ancient cache, user log files, and other clutter and helps you delete it from your Mac.

  1. Download the free version of CleanMyMac X and install it, then launch.
  2. Press Scan.
  3. Click Run.

That’s all there is to it. I managed to clear 10GB in just a couple of minutes, which saved me hours I would have spent if I were to do it manually.

macOS Big Sur requirements

Here’s the list of macOS Big Sur supported Macs:

  • Any Mac Pro or iMac Pro
  • MacBook Pro and MacBook Air 2013 and later
  • iMac and Mac mini 2014 and later
  • MacBook 2015 and later

As you can see, some Macs released as long ago as 2013 can officially run Big Sur. That’s pretty good considering the number of macOS updates there have been since then and the new features they have introduced.

Sadly, a few machines that were supported to upgrade to Catalina have fallen off the list for Big Sur, notably the 2012 MacBook Pro, MacBook Air, and iMac.

Mac models that do crash

Immediately after Big Sur's release on November 13, 2020, Mac users started reporting system failures that appeared to affect MacBooks from 2013-2014. The attempted installation resulted in 'bricking some older MacBook Pro models,' according to MacRumors. Notably, those MacBooks are the oldest still supported Macs that can run Big Sur. So if your MacBook belongs to that generation, we advice you to do little research on this before you rush to install Big Sur.

If your Mac’s model is on the list of “officially supported” Macs to run Big Sur, you will definitely be able to upgrade it to the latest OS. You can be sure the installer will run on your Mac and that if you run into trouble, you can expect help from Apple, either in the form of support documentation or an update to the OS.

But, if your Mac is slightly older and isn’t on the list, there is a possibility you can still update it to Big Sur. Several Mac users have had some success installing the Big Sur beta on Macs that aren’t on Apple’s list. It requires a workaround, and there’s no guarantee that it will continue to work when the final version of Big Sur is released or when updates are issued. But, if you’re determined to install Big Sur on an older Mac, or you want to try it as a fun project, it’s an option.

Things to consider before you try to install Big Sur on an unsupported Mac

Installing macOS Big Sur on a Mac that’s not on Apple’s official list of unsupported Macs isn’t as straightforward as just downloading the installer and running it. How you install it will depend on the Mac you’re trying to install it on, and we’ll come to that later in the article. But there are other things you need to consider.

  • Your Mac may not run at all afterwards.

If you get the installation process wrong or something just doesn’t work as it should, you could be left with a Mac that doesn’t boot. For that reason, you should make a bootable clone of your startup drive before you start.

  • Even if your Mac boots, parts of it won’t work

Among those users who successfully installed the beta version of Big Sur on unsupported Macs, most reported that either the graphics system (GPU) didn’t work or that Wi-Fi didn’t work. You can get around the wifi issue by replacing the internal Wi-Fi card or using a USB Wi-Fi adaptor, but you can’t replace the GPU.

  • There’s no guarantee updates will work

Just as you can’t use the regular installer to install Big Sur on an unsupported Mac, you won’t be able to install updates using Software Update. That could leave you vulnerable to security flaws.

How to upgrade to Big Sur on an unsupported Mac

As we said earlier, the specifics of how you install Big Sur on an older Mac vary according to the Mac, but there are lots of success stories in this thread.

One example is the user who installed the Big Sur beta on a 2012 15in MacBook Pro, and it ran well apart from Wi-Fi not working. That user got around the problem by using an iPhone as a hotspot (you can use Personal Hotspot by connecting to an iPhone via Bluetooth or USB). Another user reported installing Big Sur on a 2012 Mac mini, but with sound and Wi-Fi not working.

The question of whether or not your Mac is compatible with macOS Big Sur can’t be answered just by looking at Apple’s list of supported Macs. Those are the machines on which Apple has decided to support installation, but there are others on which Big Sur will run, albeit with a bit of extra work. You should decide for yourself whether you want to take risks associated with installing Big Sur on an unsupported Mac. And, if you decide to go ahead, be sure to back up your Mac and clean it up using Mac maintenance software like CleanMyMac X.

Update:Teensy 3.0 is supported by Teensyduino. After installation, Teensy Loader is in hardware/tools. It is run automatically when using Verify or Upload within the Arduino software. This version on this web page has not been updated for Teensy 3.0. Please install Teensyduino to use Teensy 3.0.

Files to download:

  • Teensy Loader Disk Image (4.4 megabytes, Mac OS X 10.10 and later)

When you open the disk image, it contains 1 item, the Teensy Loader application.

You may copy the Teensy Loader to your hard drive, perhaps even add it to yourdock. But it will run perfectly directly from the disk image, so just doubleclick it.

Yes, the Teensy Loader is safe, so click Open.

The Teensy Loader should appear as a small window. If theTeensy board is running the LED blink, or not connected, you should see this window.

If HalfKay is running, you should see this. If not, simply make sure yourTeensy board is connected, and press thepushbutton to run HalfKay. The Teensy Loader will quickly recognize it.

From the File name, choose 'Open HEX File' and open blink_fast.hex, which youdownloaded using the link at the top of this page. You can also open the fileusing the toolbar button, or using drag-and-drop onto the upper portion ofthe window. When the file is opened,the filename and percentage usage of the Teensy's memory are shown.

Select 'Program' from the 'Operations' menu, or click the Program button onthe tool bar. The download should be very quick, perhaps too fast to see atiny progress bar appear, but you should see the 'Download Complete' message.

Choose 'Reboot' from the 'Operations' menu, or click the Reboot button on thetool bar. Your Teensy board should immediately begin running the fast LEDblink program!

To try Automatic mode, simply click the 'Auto' button, or choose 'Automatic Mode'from the Operations menu. The Auto button should illuminate bright green.Then, open the slow LED blink HEX file.

When you press the button on your Teensy board, Automatic Mode will quicklyprogram and reboot your board. Normally, while working on a project, you canleave the Teensy Loader in Automatic Mode. Teensy Loader always reads the latestversion of your HEX file, so you can just compile your code, then press the pushbuttonto program and run your code.
