Install El Capitan On External Drive
Preparing Mac Device for the Installation of Mac OS X El Capitan Both Mavericks and Yosemite are easier to download and install on Mac devices, however, this is not the case with Mac OS X El Capitan.
- Jun 22, 2020 I've forwarded the early 2008 machine drives (unaware than getting the installer is going to be so challenging). I am unable to open the El Capitan package to get the installer on my 2019 machine. I just need a bootable version of El Capitan, or to install on an external hard drive so I can reboot my early 2008 machine.
- Quit Disk Utility and install El Capitan. If you already attached the SSD you can use Internet Recovery Mode (hold cmdR or altcmdR while booting) to first partition the new internal drive and then restore the original system (10.7 Lion). Then - after configuring Lion - you can to upgrade to El Capitan.
Trying to install El Capitan on using the USB drive method on my mid 2012 13' macbook pro (9,2) and I can't seem to get it to work at all. Using a PNY CS1311 240GB SSD. Office 2016 for mac big sur. When it begins installing El Capitan I get about a minute before it stops and says 'OS X could not be installed on your computer. Couldn't complete copy'. I've tried a few times without any luck, and upon booting my laptop for the first time with the SSD I erased, then formatted with OS X Extended (Journaled) and GUID partition map, so I know it's formatted correctly.
I've successfully installed OSX on my old HDD using the same USB drive so I'm not really sure if that's the issue.
Any advice is greatly appreciated.

I'm a bit confused by your post on what you are trying to do here. Are you trying to boot into Recovery Mode to install macOS to an external USB drive or are you trying to boot from a macOS USB installer to install macOS to the internal drive?
Here are the instructions for creating a bootable macOS USB installer:

Make sure to carefully read the section regarding macOS 10.11 as there are extra steps required to extract the real installer from the downloaded .dmg archive to the Applications folder. After running the .pkg file from the mounted .dmg file you can then proceed to use the command line to create the bootable macOS USB installer itself.
Macs are very picky about the drives used for booting a Mac plus the quality of many USB sticks is extremely poor so try using another USB stick especially a different brand.

When erasing the drive make sure to select the whole physical drive within Disk Utility and erase the physical drive as GUID partition and MacOS Extended (Journaled). The physical drive should be the top most item which is usually identified by the make & model of the drive itself.
