Check your main Applications folder or - if you have moved an older OS X El Capitan installer.app to a different folder - this second folder for the app. I have a 'Installer' folder in my user folder dedicated to OS X Installer apps (the latest but also older OS X versions) and the single installer.apps will be downloaded (or 'updated' to the. OS X El capitan.app Download. I need to make a bootable USB drive installer for a 2009 MBP. I just put in a new SSD and want to do a fresh OSX install. I believe that El Capitan is the last supported software for this hardware.
Do not try to install the version of El Capitan downloaded from the App Store Purchased page
it probably has outdated certificates.
There is no need for you to install all the OS X's to get to El Capitan you can install directly from
Mac OS X Snow Leopard 10.6.8. After you have installed Snow Leopard you need to update it to
version 10.6.8 from here,
And if the installation fails you should not have to erase the mac and reinstall Snow Leopard.
If you do have an operating system on your mac and it is functioning then you can download
El Capitan using this method.
Open your Safari browser and click on the link below,
Go to Download OS and click on OS X El Capitan 10.11
this downloads InstallMacOSX.dmg to your Downloads folder.
The next section can only be done on a mac that is capable of running El Capitan.
This includes macs that have the potential to run El Capitan but have been upgraded to a newer OS.
A mac that came preinstalled with an OS later than El Capitan will refuse to do the next bit.
When downloaded open to InstallMacOSX.pkg, double-click on
that and an installation window will open, this does not install El Capitan
El Capitan Dmg
but converts the InstallMacOSX.pkg to the Install OS X El Capitan.app which
you will find in your Applications folder, it should be 6.2GBs in size.
(If the installation window asks which disk you want to install to, you must pick
the disk that you are booted to at the time. Not any internal or external disk that
you want to eventually install El Capitan on, that is for later.)
To start the installation of El Capitan double click on the Install OS X El Capitan.app.
The copy of the install app self deletes after installing El Capitan, so make sure you keep a copy of the
InstallMacOSX.dmg if you need it in future, or you could just make a copy of the Install OS X El Capitan.app
prior to installing and moving it to an external drive for safe keeping.
It is also possible to create a bootable USB installer disk using the Install OS X El Capitan.app in the Applications
folder and the createinstallmedia command in the Terminal app.

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
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:
- macOS Catalina 10.15 hardware requirements
- macOS Mojave 10.14 hardware requirements
- macOS High Sierra 10.13 hardware requirements
- macOS Sierra 10.12 hardware requirements
- OS X El Capitan 10.11 hardware requirements
