Very many thanks for a most helpful response which I have implemented, coupled with Eric Roots DiskMaker suggestion which I have used. I created a new partition on my MacBook and, having restarted and opened into that new partition, I then installed the downloaded El Capitan and all seems to be well. Download El Capitan.DMG from here. Download DiskMaker X. To do in Windows, we already shared a very specific instruction from here: Make Bootable Installation USB from Mac OS X.DMG on Windows PC. At for Mac users, there will be 2 doable methods. METHOD 1: Using DiskMaker X. Run, DiskMaker X, then.choose El Capitan (10.11).
When Apple introduced Yosemite, it changed the way it distributes operating systems for the Mac. Now, you can’t buy a copy of the Mac OS installer. That’s a problem if you have a limited broadband connection or metered broadband connection. You’ll need to create a portable offline installer in these situations.
Download or Purchase the Mac Operating System
The first step is to go to the App Store and search for the current operating system. Currently, that’s El Capitan. If it’s already installed on your Mac, the App store will warn you the operating system is already on your system. If it isn’t already installed or you didn’t purchase it on your current Mac, under El Capitan it will say
If you’d like to create an installer for an earlier operating system you purchased, you can still do that from the App Store. Go to the
The Easy Way: DiskMaker X
DiskMaker X is a free program that does the hard work of creating the USB installer. They do take donations, so if it’s helpful to you, you might throw some money in the tip jar.
After your open the program, it finds the operating system installers on your Mac. In this example, I’ll create an El Capitan installer. Next you’ll need an 8 GB or larger disk. This media can be a USB stick, but I use an SD card. Since most Macs that run Yosemite have an SD card slot, I think it’s easier.
DiskMaker confirms the disk you want to use for the installer. Then it warns you it needs to erase that disk. Confirm again you have the right disk and then click continue. After authenticating your Mac’s administrator name and password, a few minutes later you’ll have a complete installer.
The Hard Way: Terminal Commands
If you’re more comfortable with terminal than using a third-party program, it is possible to create the installer. You’ll need a disk formatted
After you put in the password, the media creation process begins.
Why Do You Need This?
If you can download it again, why waste a flash drive or an SD card? Ideally, your Mac has a recovery partition you can boot off of to repair problems. Sometimes that partition isn’t there. An offline installer includes disk utility so you can solve problems.
The most common reason though is if your Mac’s hard drive fails. If you only have one Mac, you won’t have an easy way to reinstall the operating system. Creating the installer in advance solves the problem.
This is true for Windows too:It’s handy to have a system repair/recovery disk for Windows 7, Windows 8, or Windows 10

Finally, if you want to reinstall your OS to troubleshoot problems, waiting for the installer takes a long time. When things don’t work, you probably wait for a download. If you’re on a slow connection, the download could take several hours.
Overall for the cost of one small USB flash drive or SD card, you can have the peace of mind that you can solve your Mac problems instantly.
