These advanced steps are primarily for system administrators and others who are familiar with the command line. You don’t need a bootable installer to upgrade macOS or reinstall macOS, but it can be useful when you want to install on multiple computers without downloading the installer each time.

Step 4: Now expand the image 10.10.1.usb.arc to any Bootable USB flash drive or Bootable DVD for manual installation.What you need to create a bootable installer
*A USB flash drive or other secondary volume formatted as Mac OS Extended, with at least 14 GB of available storage
*A downloaded installer for macOS Big Sur, Catalina, Mojave, High Sierra or El CapitanDownload macOS
*Download: macOS Big Sur, macOS Catalina, macOS Mojave or macOS High SierraThese will be downloaded 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 CapitanThis will be downloaded 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 will install 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 has been erased, you may see an alert stating 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 been completed, 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

A bootable installer doesn’t download macOS from the internet, but it does require an internet connection to get firmware and other information specific to the Mac model.
For information about the createinstallmedia command and the arguments you can use with it, make sure the macOS installer is in your Applications folder, then enter the appropriate path in Terminal:
A previous commenter on our How To Speed Up Your Mac article noted that the biggest speed up they experienced for their Mac was to re-install OS X from scratch from a USB disk. Whilst this is a bit disappointing because it’s one of the things I had hoped to escape when I made the switch from Microsoft Windows all those years ago, it makes a fair bit of sense – particularly if you’re one who often plays with software then deletes it again like I do for reviewing stuff, since lots of cruft gets left laying around… (I tried using Parallels Desktop 10 to run an alternative OS X platform for doing my reviews – it was too slow).Download Mac Yosemite Installer
The process isn’t all that straight forward and the commenter asked if we would do a How To, so here it is.
The first thing you need to do, as with any major undertaking you might do with your Mac, is to BACK IT UP. Get yourself a Time Capsule from Amazon, eBay or (if you’re in Australia) somewhere like JB Hi-Fi and back up your Mac using Time Machine. Or check out our article about Crashplan if you prefer not to shell out exorbitant amounts of money on a Time Capsule. We can’t stress this enough – you must back up your Mac before continuing. The process outlined below will delete all your data. Everything. Kaboom. So back it up.Os X 10.10 Yosemite Download
While your Mac is backing itself up somehow, go to the Mac App Store and download Yosemite. It’s a big download and if you’re in Australia like me it’ll take a while thanks to our ageing infrastructure and lack of government foresight to get us into the 20th Century of broadband (but I digress into a political debate). DONT OPEN IT. The download will create a link in your Applications folder called ‘Install OSX Yosemite’. Don’t open it yet. Doing so will install Yosemite indeed, but it’ll be an upgrade over the top of what you already have and it’ll delete itself after it’s re-installed. This is not what we want if we’re putting it on a USB. If it opens automatically, simply close it.
You’ll need an 8Gigabyte USB key – which you can pick up at just about any corner store these days.
Plug the USB key into your Mac and if necessary re-format it using Disk Utility so that Yosemite can be written to it. To do this, open Disk Utility, select the USB key on the left and choose the Erase Tab. Choose Mac OS Extended (Journaled) and leave the title as ‘Untitled’ for now. The process of putting Yosemite onto the USB key will rename it anyway.
Now we’re (unfortunately perhaps) going to have to get a little bit familiar with the Terminal application. Open up Terminal (its under Applications -> Utilities if you’ve never used it before). The instruction you need to type assumes you have simply downloaded the ‘Install OS X Yosemite’ application into your applications folder. You’ll need to modify the locations if you’ve managed to download it somewhere else.
sudo /Applications/Install OS X Yosemite.app/Contents/Resources/createinstallmedia –volume /Volumes/Untitled –applicationpath /Applications/Install OS X Yosemite.app –nointeraction
The sudo command at the beginning will ask you for your login password. If your Mac logs in automatically, it’s the same password that you may have used in the pop up windows that occasionally come up when you install new programs.
The createinstallmedia command will give you some (fairly inaccurate) feedback about how far through the process it is, but you can expect it to take anywhere up to 20 minutes depending on how quick your Mac can read from the internal disk and write to the external USB which are typically quite slow. Don’t interrupt the process – don’t turn off your Mac, don’t pull out the USB key, don’t eject the USB key from Finder. Doing so will corrupt the flash key and you’ll need to start again. The process is finished when you see ‘Copy Complete. Done’ in the terminal window.
That’s the hard part over with. Now you need to reboot your Mac ( hope you’re reading this on an iPad or something similar so you can still follow while you reboot! ).
As soon as you hear the Mac bootup ‘Chime’ hold down the Option (or Alt) key and select the USB drive (which should be an orange colour). Double click the icon with the mouse or use the cursor keys to move to that image and then press Enter. This will start the Yosemite Installer, which may take a few minutes depending on the speed of your USB key. When everything is started you’ll see an Installer screen with a number of options. You need to choose the Disk Utility option first of all. If you miss this step you’ll end up just installing Yosemite over itself and you won’t benefit from a fully clean install. When Disk Utility is started click on Macintosh HD (or whatever your internal hard drive is called that you’re going to install Yosemite to) – it’s probably the top drive listed. Just as you did for the USB key, do now for the hard drive – i.e., choose the Erase Tab, choose Mac OS Extended (Journaled) and set the title to whatever you want. This will erase all your files from that disk. Everything. You did backup didn’t you?
Once that process is complete, Exit Disk Utility and choose Install OS X – choosing the freshly erased Hard Drive when the installer asks you.
Once everything is finished and you reboot, you’ll see your shiny new Yosemite install and if your Mac was anything like mine, you’ll probably think you have a new machine too because mine was considerably faster after a fresh install.User Review0(0 votes)
