In macOS, the Boot Camp Assistant app will help you partition your Mac hard drive to accommodate both operating systems, so you can install Windows from an installation disk or an ISO image stored on a USB flash drive. Select either the Install macOS Big Sur Beta, or the Install macOS Beta from the Opencore options, depending on if you created either a Beta 2 or Beta 1 USB. Install macOS as you would Catalina. Format the drive you will use to install macOS, and then install Big Sur through the on-screen prompts. It will say '3 minutes remaining for maybe 5-10. Updating Kexts is a similar process to updating OpenCore, make a copy of everything and update on a dummy USB in case there's issues The easiest way to update your kexts is via 2 tools: Lilu and Friends (opens new window) to download and compile the kexts.

A free public version of macOS Big Sur 11 has been available since November 12, 2020. It offers the best Safari we've ever seen, a huge design upgrade, and one very neat Control Center. Ready to dive in? Let's see how you can do it.

There are two ways to install a new macOS: 1) run a regular upgrade via Apple's main menu (replace your current macOS with Big Sur on your startup drive); 2) start from scratch and clean install macOS. Option number 2 is a bit more cumbersome and takes more time — but there are many benefits to it. In this article, we explain how to clean install macOS Big Sur without any trouble and why it's good for your Mac.

Why you should clean install macOS 11

As soon as the new macOS appears, we can't wait to try it. With Apple promising lots of awesome enhancements, it's hard to resist the temptation. So it's no wonder people tend to rush things and choose the quickest way to upgrade macOS — the regular install. Not only is it faster, it also allows you to maintain all your saved settings, apps, and files on a new system. But is it really something your Mac wants?

Speaking in defense of clean install, here's how it benefits your Mac:

• You get rid of the unnecessary clutter and old system bugs
• Your Mac will run faster — as if you've just recently unboxed it
• Uninstall software you never use
• Fix common problems like Mac slowing down, freezing, etc.

Generally, installing a new macOS Big Sur on a clean drive will give your Mac enough space to breathe. You'll be less likely to experience common Big Sur problems and you'll get a chance to keep only the data you really need. It's like you bring the new furniture in an empty apartment instead of a cluttered one.

macOS 11 compatible Macs

Before you take any steps to switch to Big Sur, make sure you check compatibility. With the release of macOS 11, Apple moved a year or two ahead in terms of supported devices, so the chances are your Mac might be off the list (ouch). Here are the Macs that support Big Sur:

• MacBook (2015 or later)
• MacBook Air (2013 or later)
• MacBook Pro (2013 or later)
• Mac Pro (2013 or later)
• Mac Mini (2014 or later)
• iMac (2014 or later)
• iMac Pro (2017 or later).

Not sure which model you have? You can easily check it by clicking on the Apple icon > About This Mac. You'll find the information you're looking for in the Overview section.

Steps to clean install Big Sur

Once you've decided to start anew with macOS Big Sur, you're only six steps from achieving your goal. Make sure you follow all of the steps and have a safe experience.

Step 1: Remove all the junk

When we say that clean installation removes everything from your Mac, we forget one important detail — a backup. If you back up your Mac before upgrading, you'll be able to restore all your files on the new macOS (and with it all the clutter your old system contained.) You want the files back, but you don't want the clutter. So the first step should be a thorough cleanup of your system.

No worries, it only sounds intimidating. Apps like CleanMyMac X allow you to remove all the clutter — from old caches to file duplicates — in one click. Here's how to get ready for your Mac backup:

1. Open CleanMyMac X > Smart Scan

2. Wait a few seconds for CleanMyMac X to finish the scan

3. View the unneeded files detected by CleanMyMac X and click Remove.

You can also choose to remove system junk only (find the option in the Cleanup section). This will delete most of the redundant files and let you reclaim lots of storage space. Still, a smart scan cleanup will do a better job while it can also detect potential malware and provide insights into your Mac's performance. So if you have a couple of minutes, spend it on Smart Scan.

Step 2: Create a secure backup of your Mac

Many people use Apple's native Time Machine to back up their files, but we don't recommend it. Users report Time Machine tends to carry over macOS issues into new installations. What's more, Time Machine can't do bootable backups, which means you'll have to go through a long restoration process in case there's a drive crash or an error of any kind. Utorrent 64 bit for mac.

Get Backup Pro is a third-party backup utility that makes sure you run zero risks when you clean install Big Sur. And not only Big Sur. It's generally the best alternative to Time Machine we've seen so far. Get Backup Pro allows you to create both backups and bootable clones so you can easily take your data to a replacement drive in case something goes wrong. Plus, you get great features like compression, backup scheduling, and the ability to choose specific files for a backup.

Here's how to back up your Mac before the Big Sur upgrade:

1. Open Get Backup Pro and select Backup in the sidebar
2. Click on the plus button to create your backup project
3. Customize destination (make sure you save your backup to an external drive)
4. Add files and apps data to your backup by clicking on the plus button
5. Hit the Backup button (it looks like the Play button) to start the process.

Step 3: Download the Big Sur installer

Starting November 12, you'll be able to access the Big Sur installer in the Apple menu > About This Mac > Software update. Alternatively, you can download the installer from the Mac App Store. It's free and effortless.

But be careful, it's important to not rush things here. Your goal is to save the installer to your Applications folder and not to go through the installation process. So if the installer automatically launches, don't click Continue. Close the window by clicking on 'Quit install.' You'll use the installer later when you clean install macOS.

Step 4: Create a bootable USB installer

Prepare a flash drive USB with at least 16GB of free storage. Connect it to your Mac and start creating a bootable USB installer. First, you'll need to erase everything from your drive:

1. Access Disk Utility on your Mac
2. Select your drive from the list of internal drives and click Erase
3. Set the format to Mac OS Extended
4. Confirm that you want to erase the drive.

Next step, open Terminal and enter the following command:

sudo /Applications/Install macOS Big Sur.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled

Remember, 'Untitled' is the name of your connected drive. If you name it differently, make sure you replace the name in the Terminal command.

Press Return and Y. You might need to type your admin password to confirm your action. Once the process is complete, click Done and close Terminal. That's it. You just created a bootable USB installer that's based on the Big Sur installer you had downloaded before.

Step 5: Erase your startup drive

Python 3 7 alpine trail. Time to say goodbye to your old macOS. Erase your startup drive fearlessly — you have your most important files securely backed up. Here are the three steps:

1. Shut down your Mac and hold down Command + R to enter the Recovery Mode
2. Access Disk Utility and select your main startup drive
3. Click Erase in the menu and confirm your action.

Step 6: Clean install macOS 11 Big Sur

Finally, here's how to do a clean install of macOS using your USB installer drive:

1. Restart your computer and hold down Option
2. Go back to the initial screen of Disk Utility
3. Choose to install macOS from the connected USB drive
4. Click on Install macOS to confirm your action. Breathe out. And go celebrate!

How to reinstall macOS Big Sur

If you're not ready to go celebrate because the installation didn't work, you can try to reinstall Big Sur. All you have to do is restart your Mac and boot in Recovery Mode (Command + R), then click on Reinstall macOS. Hopefully, it works this time.

How to run a regular macOS update

If you don't want to clean install Big Sur just yet, you can place the new update on top of your current drive, which will preserve all the settings. If your Mac runs on OS X Mavericks or later, you can update directly to Big Sur. Note that Apple recommends you have around 35.5GB available storage and 4GB of memory on your macOS before upgrading. This will be easy to achieve by removing unnecessary files with CleanMyMac X.

Also, even if you run a regular update, do make sure you back up all your data with the Get Backup Pro app. Some might call it an unnecessary precaution. We call it a one-click process that will keep your files safe under any circumstances.

Here's how to run a standard macOS Big Sur installation:

1. Click on the Apple icon in your menu bar > About This Mac
2. In the Overview section, click on Software Update
3. Click on Update Now to download the installer
4. Follow the installation instructions on your screen.

Overview

If you wish to run both macOS and Windows on a single Mac computer, UITS recommends using Apple's Boot Camp utility to install a 64-bit version of Windows on your Mac. In macOS, the Boot Camp Assistant app will help you partition your Mac hard drive to accommodate both operating systems, so you can install Windows from an installation disk or an ISO image stored on a USB flash drive.

Pre-installation notes

• This guide is written for macOS High Sierra, version 10.13.x or newer. If your computer cannot run macOS High Sierra version 10.13.x, you will need to follow Apple's Boot Camp Help: Install Windows on your Mac. If you don't have access to the online guide via a different device, print a copy of the Boot Camp Installation & Setup Guide.
• Determine whether your computer can run Windows 10; refer to Apple's System requirements to install Windows on your Mac using Boot Camp.
• To determine if your Mac supports this feature, open Boot Camp Assistant (Go > Utilities > Boot Camp Assistant), and then click Continue. If you see a 'Create a Windows 7 or later install disk' checkbox, your Mac supports this feature.

• Make sure your computer meets these requirements:
  • At least 80 GB of free hard drive space
  • You have either the keyboard and mouse (or trackpad) that came with your Mac, or a USB keyboard and mouse
• Obtain a USB flash drive (at least 16 GB).
• During installation, you will be prompted to enter an account name and password; this is for the administrator account, and should not be the one you generally use. You also will be prompted to enter your time zone.
• Ensure that the computer is plugged into a power source, as the entire process may take several hours.

Installation guide

• These instructions are intended strictly as a guide for installing a fully updated 64-bit version of Windows on a macOS High Sierra 10.13.x or newer computer at IU; if your computer cannot run that version of macOS, you'll need to follow Apple's Boot Camp Help: Install Windows on your Mac.
• Perform these steps in order.

Step 1: Check for macOS updates

Before configuring Boot Camp, it is critical to make sure that your Mac's software is up-to-date, which lessens the risk of encountering problems during installation:

1. In the menu bar, from the Apple menu, click App Store.
2. At the top of the window, click Updates.
3. If there are updates for your computer, in the upper right corner of the window, click Update All.

   If you're prompted, enter an administrator's username and password, and if prompted, allow your computer to restart.

When your computer restarts, check for additional updates by repeating the steps above. Repeat the process until there are no new updates in the App Store.

Step 2: Confirm your macOS version

In the menu bar, from the Apple menu, click About This Mac. The window will display the version of macOS on your computer. If you aren't running macOS High Sierra (10.13.x), you need to follow Apple's Boot Camp Help: Install Windows on your Mac.

Step 3: Turn off FileVault

To proceed, you need to divide your Mac's hard drive into a section for macOS and a section for Windows. This process is called partitioning a disk, and requires that you disable FileVault (whole-disk encryption provided by Apple):

1. In the menu bar, from the Apple menu, click System Preferences.
2. Click Security & Privacy.
3. Click FileVault. The FileVault control panel will open, locked by default.
4. Before you can disable FileVault, it requires you to unlock the control panel to show that you're an administrator on your computer. To do so, click the lock icon. Enter your administrator username (if required) and your password.
5. You'll then be able to click Turn Off FileVault... To confirm, click Turn Off Encryption.

   Decrypting an encrypted drive can take some time, the exact time being determined by how much data is on your disk, the disk size, and your computer's hardware capabilities.

Step 4: Download Windows 10

The version of Windows 10 on IUware will not work with Boot Camp; you'll need to download Windows directly from Microsoft, and use a product key you get from IUware.

Downloading Windows 10 Education takes some time, depending on the speed of your internet connection. Do not attempt the download on a metered connection, such as a tethered cell phone.

3. To select the installation tasks to complete, make sure Create a Windows 7 or later version install disk and Install Windows 7 or later version are both selected.

   Before continuing, make sure a USB drive (at least 16 GB) is connected to the system, and be aware that the entire contents of that flash drive will be erased.

4. On the next screen, make sure the ISO file you just downloaded from Microsoft and the appropriate flash drive are both selected. Click Continue.
5. To confirm that the drive will be overwritten, click Continue.

   This step will take some time, depending on your computer's hardware capabilities and your internet connection speed. Make sure your computer remains plugged into an AC outlet during this process.

6. To begin creating a partition on your Mac's hard disk to hold Windows, authenticate with your administrator password.
7. Use the slider between the Mac and Windows icons to select a size for the Windows partition.

   UITS recommends that you use 80 GB for just Windows, and 90 GB for Windows plus Microsoft Office.

2. To select the keyboard layout, make sure US is selected, and click Yes.
3. If you would like to add a secondary keyboard layout, use the next screen to do so; otherwise, click Skip.
4. On the 'Let's connect you to a network 'screen, click Skip for Now.

Step 8: Create your Windows administrator account

1. To create your account, type your name and click Next.
2. Type a password and click Next. Do not use your IU network passphrase.
3. Confirm your password by typing it again, and click Next.
4. Select a series of three security questions, clicking Next after each one.
5. Decide whether or not you want to use Cortana in Windows. Decide what privacy settings you would like to enable or disable, and click Accept.
