I haven't updated my MacBook Pro in many years. In fact, I'm still on Snow Leopard (MacOS X 10.6.8). This is a version so old that all the steps I read to make a bootable USB drive failed. I wasn't able to use createinstallmedia to make a boot disk because that doesn't work until MacOS X 10.7. Nearly all the steps I read online regarding using "Disk Utility" to make a bootable USB drive failed until did the following steps:
1. link.
2. After downloading, it will automatically launch the upgrade installer. Quit with Command+Q.
3. Go to "Applications/Install OS X El Capitan" and Control+Click to প্রদর্শনী the context menu and select "Show Package Contents".
4. Open "Contents" and then "Shared Support" and copy the "InstallESD.dmg" file to the Desktop. (Drag to the desktop.)
5. After the copy is complete, double click on "InstallESD.dmg" to mount the volume. It should mount as "OS X Install ESD".
6. This is where most instructions seem to stray off the correct path. There is actually a hidden file called "BaseSystem.dmg" in the root directory of the "OS X Install ESD" volume that was just mounted. To প্রদর্শনী the hidden file, আপনি can change the system settings to প্রদর্শনী all hidden files অথবা just open it using the Terminal which is what I did. Run "Application/Utilities/Terminal" and type at the prompt:
open /Volumes/OS\ X\ Install\ ESD/BaseSystem.dmg
This opens the hidden "BaseSystem.dmg" file and mounts it as "OS X Base System".
6. Plug in your USB device that is larger than 8 GB that you'll be making bootable and putting the El Capitan installer on. You'll want to copy any data আপনি want to save off of it at this point. I used a brand new SD Card (plugged into a USB adapter), so I didn't have anything to backup.
7. Run "Applications/Utilities/Disk Utility" and আপনি should see "InstallESD.dmg" with "OS X Install ESD" volume and "BaseSystem.dmg" with "OS X Base System" volume in the left sidebar. আপনি should also see the USB device আপনি have plugged in. Click on the USB device and select the "Erase" tab. Choose "Mac OS Extended (Journaled)" and click on "Erase...". নিশ্চিত আপনি want to erase the USB device and type in your admin গুপ্তশব্দ if prompted. I think this step might not be necessary, but it's part of what I did.
8. Once the erased, click on the Restore tab and drag "OS X Base System" into the উৎস field. Then Drag the newly erased volume of your USB device into the Destination field. Click Restore. (Type your admin গুপ্তশব্দ if prompted.)
9. After the "OS X Base System" has been copied onto the USB device, go ahead and eject the BaseSystem.dmg drive. Ejecting is a good idea because there are now two volumes named "OS X Base System" and we don't need the one in BaseSystem.dmg anymore.
10. Open the USB drive's volume (which has been automatically renamed to "OS X Base System"). Go to "System/Installation" in that volume and আপনি should see a "Packages" alias file. মোছা the "Packages" alias; we'll be replacing it with a copy of the actual Packages folder.
11. Open the "OS X Install ESD" volume (the one from the InstallESD.dmg file copied to the desktop) and there should be a folder called "Packages". Drag the "Packages" folder over to the "Installation" folder of the USB drive to copy it.
12. There are also two hidden files that need to be copied from "OS X Install ESD" (from InstallESD.dmg) to the root directory of "OS X Base System" (the USB drive). To প্রদর্শনী hidden files, open a Terminal to issue a command to প্রদর্শনী all files including hidden ones and to stop all existing Finder windows (new ones will heed the setting). To do this, open a Terminal and type:
defaults write com.apple.finder AppleShowAllFiles TRUE
killall Finder
13. Now Finder windows should প্রদর্শনী the hidden files. Copy both "BaseSystem.chunklist" and "BaseSystem.dmg" from "OS X Install ESD" partition over to the "OS X Base System" partition (the USB drive).
14. For cleanliness, hide the hidden files again দ্বারা typing in a Terminal:
defaults write com.apple.finder AppleShowAllFiles FALSE
killall Finder
15. After the copy of "Packages", "BaseSystem.chunklist", and "BaseSystem.dmg" is complete, আপনি should have a bootable USB drive that can install El Capitan on a Snow Leopard machine. Just restart and hold down Option as soon as the screen turns black and don't let go until the boot loader screen appears. আপনি should be able to choose the USB drive volume to boot from. If আপনি don't see the drive, আপনি might need to press Option+Shift+Command+. (Period) to force load Option ROM firmware code.

I made this short article, basically as a warning to any headphone users to be aware of what risk these headphones(same for any in-ear earbuds) can have.
I’ve used আপেল wired ear pods as my daily driver for years. I’ve tried going at lower volume to reduce any hearing risk, but...it didn’t really work.
In result of shoving the sound উৎস so close to your ear it can risk ear ringing(tinnitus), a symptom of Noise Induced Hearing Loss(NIHL).
Ear ringing is not pretty. It’s annoying and miserable, especially in quiet places.
