Apple El Capitan Bootable Usb

Here is a detailed guide on how to make an Mac OS X El Capitan bootable USB flash drive using DiskMaker X, the easiest and most user-friendly method. – Fixes an issue that caused USB audio devices to. Those are recommended updates if you’re not running El Capitan, both available from the  Apple menu. I was having this too. I finally had success by copying the install app/folder from /Applications to the desktop. Once there the 'mount of outer dmg' message was no more, despite using the same command (other than the appropriate path changes).

Hey there. I've got an iMac 27' mid 2011 which has a dying hard drive inside, which is causing it not to boot. The only other Mac I have around is a PowerMac G5. I've read in the Apple Support forum that you need a system running El Capitan or later to use createinstallmedia, but I don't really have another choice, except on windows (which I haven't read anything on about this).

What I want to do is create a bootable USB drive with any recent enough OS for the iMac (I believe it can run anything from Mountain Lion to High Sierra, it was previously running High Sierra).

To get the latest features and maintain the security, stability, compatibility, and performance of your Mac, it's important to keep your software up to date. Apple recommends that you always use the latest macOS that is compatible with your Mac.

Learn how to upgrade to macOS Big Sur, the latest version of macOS.

Check compatibility

Apple El Capitan Bootable Usb On Windows

The version of macOS that came with your Mac is the earliest version it can use. For example, if your Mac came with macOS Big Sur, it will not accept installation of macOS Catalina or earlier.

If a macOS can't be used on your Mac, the App Store or installer will let you know. For example, it might say that it's not compatible with this device or is too old to be opened on this version of macOS. To confirm compatibility before downloading, check the minimum hardware requirements:
