Software installation with Mac OS X is very different than in the Windows world. On a Windows PC you run an installer, tick off a few checkboxes, and wait for the progress meter to reach completion.
What you need to create a bootable installer
- A USB flash drive or other secondary volume formatted as Mac OS Extended, with at least 14GB of available storage
- A downloaded installer for macOS Big Sur, Catalina, Mojave, High Sierra, or El Capitan
Download macOS
- Download: macOS Big Sur, macOS Catalina, macOS Mojave, or macOS High Sierra
These download to your Applications folder as an app named Install macOS [version name]. If the installer opens after downloading, quit it without continuing installation. To get the correct installer, download from a Mac that is using macOS Sierra 10.12.5 or later, or El Capitan 10.11.6. Enterprise administrators, please download from Apple, not a locally hosted software-update server. - Download: OS X El Capitan
This downloads as a disk image named InstallMacOSX.dmg. On a Mac that is compatible with El Capitan, open the disk image and run the installer within, named InstallMacOSX.pkg. It installs an app named Install OS X El Capitan into your Applications folder. You will create the bootable installer from this app, not from the disk image or .pkg installer.
Use the 'createinstallmedia' command in Terminal
- Connect the USB flash drive or other volume that you're using for the bootable installer.
- Open Terminal, which is in the Utilities folder of your Applications folder.
- Type or paste one of the following commands in Terminal. These assume that the installer is in your Applications folder, and MyVolume is the name of the USB flash drive or other volume you're using. If it has a different name, replace
MyVolume
in these commands with the name of your volume.
Big Sur:*
Catalina:*
Mojave:*
High Sierra:*
El Capitan:
* If your Mac is using macOS Sierra or earlier, include the --applicationpath
argument and installer path, similar to the way this is done in the command for El Capitan.
After typing the command:
- Press Return to enter the command.
- When prompted, type your administrator password and press Return again. Terminal doesn't show any characters as you type your password.
- When prompted, type
Y
to confirm that you want to erase the volume, then press Return. Terminal shows the progress as the volume is erased. - After the volume is erased, you may see an alert that Terminal would like to access files on a removable volume. Click OK to allow the copy to proceed.
- When Terminal says that it's done, the volume will have the same name as the installer you downloaded, such as Install macOS Big Sur. You can now quit Terminal and eject the volume.
Use the bootable installer
Determine whether you're using a Mac with Apple silicon, then follow the appropriate steps:
Apple silicon
- Plug the bootable installer into a Mac that is connected to the internet and compatible with the version of macOS you're installing.
- Turn on your Mac and continue to hold the power button until you see the startup options window, which shows your bootable volumes.
- Select the volume containing the bootable installer, then click Continue.
- When the macOS installer opens, follow the onscreen instructions.
Intel processor
- Plug the bootable installer into a Mac that is connected to the internet and compatible with the version of macOS you're installing.
- Press and hold the Option (Alt) ⌥ key immediately after turning on or restarting your Mac.
- Release the Option key when you see a dark screen showing your bootable volumes.
- Select the volume containing the bootable installer. Then click the up arrow or press Return.
If you can't start up from the bootable installer, make sure that the External Boot setting in Startup Security Utility is set to allow booting from external media. - Choose your language, if prompted.
- Select Install macOS (or Install OS X) from the Utilities window, then click Continue and follow the onscreen instructions.

Why Move Downloads Folder?
There may be different reasons why people want to move their Downloads folder location.
These days many of the Apple Macs come with solid state drives (SSD) which are not as large in volume/capacity as the hard disk drives (HDD) used to be. For example, the standard Macbook Pro Retina comes with 256GB of SSD space. Some of that is used for the operating system and then you are left with very little for photos, downloads, files, apps, etc.
Mac Os Default Download Folder
As a result of new Macs with smaller internal storage, you may want to move your Downloads folder to another volume such as an external drive, flash drive or SD card connected to your Mac. Yes, you can move your downloads folder permanently to another volume like this.
How To Move Mac OS Downloads Folder
Follow these steps to move your Downloads folder on Mac OS to another location:
1. Create New Downloads Folder
Go to the location where you want your new Downloads folder to be and create a folder named “Downloads“.
For example, I have an external drive plugged into USB where I want the Downloads folder to be. So I find my external drive in Finder and create a new “Downloads” folder there.
2. Copy Existing Downloads Over
If you want to keep your existing downloads, you’ll need to copy it over.
Simply use the Finder app to drag and drop the contents of the existing Downloads folder to the new Downloads folder.
3. Delete Old/Default Downloads Folder
In order to create a symbolic link in step 4 below, you’ll need to delete the old/default Downloads folder in Mac OS. It may not be possible to delete the old/default Downloads folder in Finder directly due to permissions on the folder so you’re better off doing it in the Terminal using sudo command.
Open the Terminal app and type the following command followed by your password for your account:
Note that this deletes your old/default Downloads folder with all it’s contents.
4. Create Symbolic Link
Next you’ll create a symbolic link from the default Downloads folder in Mac OS to the new one in the other location.
Open the Terminal and type the following command:
Mac Os Downloads Folder Download
Note that command creates a link (ln command) between a target and source directory. The -s
parameter creates a symbolic link.
Be sure to change /Volumes/My Passport 1/Downloads/
with the absolute path to your new Downloads folder you created in the new location. In my case, Mac OS gave my external drive the path /Volumes/My Passport 1/
and then I add the /Downloads/
part to the path in the command. The backslashes in the path is simply to escape the spaces in the folder name of the external drive.
If you’re not sure what the path to the new location is and you’re using either an internal or external storage, you can use the Disk Utility app in Mac OS to determine the mount point.
Mac OS Downloads Folder Moved!
That’s it, you’re all done moving your Mac OS Downloads folder.
The symbolic link you created in step 4 will ensure that any applications putting downloads in the old location ~/Downloads
will go to the new Downloads folder in the new location so that you don’t have to go and edit the Downloads folder in individual applications.
