File installESD.dmg On My Mac SSD with High Sierra

I have the following directory in Mac SSD after installing High Sierra:

Can the file installESD.dmg be safely deleted, to gain back 6 GB of storage, or is it still of use in High Sierra?


And what about the other files in this directory (which I don't mind keeping, since they occupy little space).

The files in question appear to be left over from a previous El Capitan install based on the fact they are two years old and one is marked OSX_10_11…


As long as you have a current backup, I would say they are safe to remove.

This is what I remembered from the past…

If you're in Windows, you can switch to the Mac OS X partition using the Boot Camp icon in the System Tray. Click the gray diamond-shaped icon, and click "Restart in Mac OS" from the pop-up menu. Then, confirm your choice to reboot to Mac OS X and give the computer about a minute to make the switch.

If that no longer works you just have to hold the Option key when you restart to choose between the two.
