The Mac App Store is the default way to upgrade or install macOS, but it doesn’t work for everyone. Maybe you’ve got multiple Macs and a limited amount of bandwidth, and don’t want to download the entire operating system for every system. Or maybe you’re looking to install the operating system from scratch.
May 18, 2018 Now copy this InstallESD.DMG as you need it in TransMac to Create macOS High Sierra Bootable USB Installer on Windows 10. Ok, so lets continue with TransMac Restore Disk Image to Drive. On this screen, select the InstallESD.DMG file and click OK. Download the macOS Sierra installer and Disk Creator. Insert an 8GB (or larger) flash drive. If you have any other data on that flash drive, back it up now, because the installer will delete.
Macworld also has bootable-install-drive instructions for: High Sierra (macOS 10.13) Sierra (macOS 10.12) El Capitan (OS X 10.11) Yosemite (OS X 10.10). Aug 02, 2017 If you want the ability to perform a fresh and clean install of macOS High Sierra, then you should consider creating a bootable macOS High Sierra USB install drive. Not only will this walkthrough.
Whatever your reason, installing macOS from a USB drive isn’t hard. You just need a few things:
- An 8GB USB drive. This process will overwrite the entire drive, so back up anything stored on it. If your drive is larger than 8GB, and you’d like to use the rest of the drive for something else, you could use Disk Utility to partition the drive: just create an empty, 8GB partition for the installer.
- Access to at least one working Mac with access to the Mac App Store. This can be a friend’s machine if necessary.
That’s it! Once you have those things we can get started.
First, Download macOS From The Mac App Store
To begin, you need the installer for whatever version of macOS you want on a thumb drive. Head to the Mac App Store. If what you’re looking for is the latest version of macOS, search for that operating system and click the “Download” or “Install” button.
The download will take a while, so make sure your Mac is plugged in and has a consistent connection to the Internet. The installer will load when the process is done; simply close the window, then head to your Applications folder to confirm the installer is there.
If you don’t want the latest version of macOS, searching the App Store won’t help you. Instead, you’ll have to head to the “Purchases” tab in the installer and scroll down until you find the version of macOS you want on your thumb drive.
You will only find versions you’ve previously downloaded here. Click the “Download” button to the left of the release you want to install, and your Mac will download it. Again, the installer will launch when the download is complete; close the window when this happens. We’re now ready to create our disk. There are two ways to do this: one with third party software, and another with the Terminal.
The Easy Way: With DiskMaker X
The simplest way to create a boot USB drive is to download DiskMaker X and use it to create your drive. Generally, the latest version supports only the latest version of macOS; if you want to install something older than macOS High Sierra, check the list of older versions and download one that’s compatible with your chosen operating system.
Installing is simple: just mount the DMG, then drag the program to your Applications folder.
Start the program and it should find the installer you downloaded above. If you’ve put the installer somewhere besides the Applications folder, you can direct DiskMaker X to the file manually.
After that, you’ll be asked which disk you’d like to use. Choose the drive or partition, knowing that it will be completely overwritten.
Once you authorize the action, DiskMakerX will mostly run in the background. When the process is done you’ll hear a loud lion roar (seriously, it freaked me out), and you’ll see the completed drive.
Diskmaker X also offers a variety of utilities, which can come in handy. The Terminal method, outlined below, does not include these.

The (Slightly) Harder Way: With the Terminal
If you’d rather not rely on a third-party tool to create your disk, Apple offers a built-in Terminal-driven method outlined here. To summarize: there is a script, called
createinstallmedia
, included in every macOS installer, and we’re going to run it.First, insert your thumb drive and give it a name—I’m using “Installer” for the purposes of this writeup, but make note of whatever name the drive has.
Next, let’s find the installation script. Open the Terminal, which you can find in Applications > Utilities, and run the following command. Note that the exact command will vary depending on which version of macOS you’re trying to install; this one is specific to Sierra.
In case you’re curious, here’s how this breaks down:
- To run the command as root. This means the command must start with
sudo
/Applications/Install macOS High Sierra.app/Contents/Resources/createinstallmedia
is the location of the script. Obviously, change “High Sierra.app” to whatever version you’re installing.- To provide the application with a path to the volume that will be overwritten. In our case, this is
/Volumes/Installer
- To provide the application with a path to the installer package. For macOS Sierra, this is
/Applications/Install macOS High Sierra.app
You will be asked to confirm that you’re ready for the disk to be deleted:
Yet “y”, then Enter, and the process will begin. First the disk will be deleted, then the entire installer will be copied to your disk.
The process will take a while, but when it’s done you’ll have a bootable drive with the installer.
Notice that the Utilities folder, offered by DiskMaker X, is not here.
The command above is specifically for High Sierra (and a disk named “Installer.”) Previous versions of macOS will have slightly different names. Here’s the complete command for a few recent releases:
- Sierra:
sudo /Applications/Install macOS Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/Installer --applicationpath /Applications/Install macOS Sierra.app
- El Capitan:
sudo /Applications/Install OS X El Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/Installer --applicationpath /Applications/Install OS X El Capitan.app
- Yosemite:
sudo /Applications/Install OS X Yosemite.app/Contents/Resources/createinstallmedia --volume /Volumes/Installer --applicationpath /Applications/Install OS X Yosemite.app
- Mavericks::
sudo /Applications/Install OS X Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/Installer --applicationpath /Applications/Install OS X Mavericks.app
Hopefully you get the idea: you need to run the script from within the installer itself, point to your drive, then point to the installer.
How to Boot From Your Installation Drive
Now that you’ve created an external installer, you need to boot from it on your target Mac. Shut the Mac down, then plug in your installer disk. Turn the Mac on while holding the Option key. You’ll be asked which drive to boot from:
Pick the drive you wrote the installer to. The installer for macOS will boot from it, at which point you can upgrade macOS, or install a fresh version.

Get Setapp, a toolkit with fixes for all Mac problems
Normally when you install a new version of macOS, you just install it over the previous version. It’s quick, easy and means we can be back up and running in no time, with all your apps and data ready to use. Your data remains but your software and file junk remains as well.
That’s why, sometimes, it makes more sense to run a clean install. Whether it’s because your Mac has accumulated so many junk files that it’s performance is badly affected or because you’re passing your Mac onto someone else and want to make sure all your data is removed. Or maybe you just want that fresh out of the box Mac experience again. Whatever your reasons, here is how to clean install macOS High Sierra.
How to prepare your Mac for the clean install
Before you do anything, check that your Mac is able to run Apple's new operating system.
To complete the clean install procedure described below, you'll need:
- macOS High Sierra Installer,available from the Mac App Store.
- a 16GB or larger USB flash drive
Notice: USB drive is needed for a clean install on your Mac’s startup drive. If you plan to clean install macOS on a non-startup drive, you don't need it. - go for a system cleanup and backup your data - this will allow you to easily return your Mac to the condition it was in before you installed macOS.
- and an hour or two to spare.
Choose the right way to clean install macOS High Sierra
Before you proceed, you need to make a choice how to run a clean install. If you only have one drive and it’s not partitioned and this is where you have all your files and your OS, your choice is to clean install on the startup drive. This way entails one important fact: all your files and data will be deleted during the process.
If you have another drive or volume other than your startup drive, use the second way which is clean installing on a non-startup drive. It’s a more lenient and less intrusive way because your Mac doesn’t get wiped clean, only your system.
If you don’t know which one you have, go with the first option, startup drive.
How to clean install macOS on a startup drive
Once you have everything that's needed, let's begin. Don’t worry, this step-by-step guide will walk you through all you need to do.
You don't need to dig through Internet to search and and download each apps mentioned below, all of them available on Setapp. With Setapp, you always have the latest full version of every app. Cancel anytime. Signup to try Setapp for free.
The process of performing a clean install involves wiping your Mac’s main drive clean so it’s essential that you back it up immediately before you start. You might not want to backup the files you don’t need and system junk, so make sure to clean that up beforehand. An easy way to go about this is to get a Mac cleaning app like CleanMyMac. It will save to hours of manual file cleanup and polish your system before the backup.
Start with a system cleanup
Delete everything you don't need - large and old files and archives, useless apps, cache data and other junk, duplicate files - all these files silently eat up the disk space, duplicate images are especially hard to find out.
You can always use CleanMyMac to cleanup macOS system junk, large and old files, and remove unwanted apps. You could do it manually, but CleanMyMac only all it takes is a few clicks.
Then you can use Gemini to easily find duplicate files and folders on your hard drive, so you can delete them and save precious storage space.
Backup your data
Now, for the backup itself use Get Backup Pro. It’s more powerful than Apple’s own Time Machine. It’s also a good idea to create a bootable clone, so if anything goes wrong you can go back to where you started easily. Also, a cloned drive makes copying files back to your newly-updated system very easy. And move your images and documents into the cloud or to an external drive, just to be on the safe side.
As well as backing up your Mac, you should also take screenshots of settings in any apps you’ve customized so that you can set them up again quickly later. And make sure you have a record of license codes for apps and passwords for websites.

Create a bootable macOS installer
- Download macOS High Sierra from the App Store. Here is a link to find it on apple.com.
- When it’s finished, the installer will launch. As soon as it does, select File and Quit (or keyboard shortcut Command-Q) so it doesn’t install. The installer will remain in your Applications folder.
- Plug in the USB stick and launch Disk Utilities.
It’s a good idea to use a USB stick to put the bootable installer onto. It will need to be at least 8GB in size. - Click the Erase tab and make sure Mac OS Extended (Journaled) is selected in the format tab.
- Give the USB stick a name, then click Erase.
- When it’s finished, click Done and close Disk Utility.
- Launch Terminal either by searching for it in Spotlight or navigating to the Utilities folder in Applications.
- Type, or paste, the following command into Terminal, where [YOUR DRIVE NAME] is the name you gave the installer drive when you formatted it:
sudo /Applications/Install macOS High Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/[YOUR DRIVE NAME] --applicationpath /Applications/Install macOS High Sierra.app
Notice: Remember to replace [YOUR DRIVE NAME] with the name of your installer disk. - Hit Return.
- Type in your admin password and wait.
- When the process is finished, the word Done will appear in the Terminal window.
- You can then quit Terminal.
Install macOS on your startup disk drive
Make sure you backup your Mac to keep your important files, before taking next step, that erase your Mac’s Startup drive.
To erase your Mac’s main drive:
- Go to System Preferences
- Сlick Startup disk and choose the installer you just created.
- Restart your Mac and hold down Command-R to boot into recovery mode.
- Take your bootable USB and connect it to your Mac.
When the macOS Utilities screen appears, follow these steps:
- Select Reinstall a new copy of macOS.
- Click Continue, then click Continue again when the next window appears.
- Agree to the terms and conditions, then select your Mac’s internal drive.
- Click Install.
- Wait for macOS High Sierra to install and your Mac to restart.
When your Mac has restarted, you’ll need to follow the process of setting it up as if it was a brand new Mac. So, you’ll need to connect to your wifi router and type in the password. Then you’ll need to type in the details for your iCloud account. Then you’ll have to set up a new admin user account.
Once you’ve done that, you can start installing apps. In order to re-install Setapp apps, go to setapp.com to get Setapp installer or download Setapp here. You’ll need your username and password.
It’s a good idea to only download those apps you need to use straight away. Other apps can be downloaded as and when you need them. That way you avoid cluttering up your brand new macOS.
If you use a cloud service like Dropbox, now is the time to re-connect. And you can copy any documents, photos or other files you need from the backup you made at the start.
