Hello everyone.
If you want a GUI, you need the latest version of Diskmaker X app. Version 5 is the one with official El Capitan support. Diskmaker X is free to download, but the creator accepts donations if you. If you don't want to use Diskmaker X, Apple has actually included a terminal command that can create an install disk for you. Assuming that you have the OS X El Capitan installer in your Applications folder and you have a Mac OS X Extended (Journaled)-formatted USB drive named 'Untitled' mounted on the system, you can create an El Capitan install drive by typing the following command into the.
I tried DiskMaker but I had problems in creating the bootable disk.
I bought a new pen drive and downloaded El Capitan in my Applications folder; I downloaded DiskMaker X 5, too and ran it.
At the very beginning I had some problems when DiskMaker attempted to format pen drive before starting copying files into it (it refused to format, returning an error).
Then, I formatted drive by hand (using Disk Utility) using a FAT filesystem (I discovered that DiskMaker not even starts formatting pen drive when it is initialised with a Mac OS X Journaled filesystem).
Corel draw x7 dll files. Thus, DiskMaker started and finished formatting pen drive; later on, the copying of files begun but I noticed soon it was taking too much time (it seems it should take at the most 30 minutes); in fact, after almost 45 minutes, a time out error (regarding a certain AppleEvent) is returned and the process of copying seems to be aborted. There are some folders on pen drive but I'm sure enough not all files have been correctly copied. Moreover, folders have a pale colour, as it happens for hidden files when they are shown in finder (is it normal?).
Is there a solution to this problem?
Is there an alternative way (for instance, by shell) to obtain a bootable disk (supposing error derives from DiskMaker)?
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. 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. The version of macOS that came with your Mac is the earliest version it can use. To confirm compatibility before downloading, check the minimum hardware requirements:. 
Thanks for support.
