Q: el capitan usb boot drive
created a usb boot drive for el capitan. it appears to be a good down load from app store. used disk maker x to create the usb. no problem. get to the point of installation and get an error message pertaining to possible corrupt file or invalid certificate. did some research and found after February 2016, apple stopped validating el capitan, maverick, and so on. any suggestions?

I do not understand this reference, maybe you could post your source.
Try making the bootable installer using the createinstallmedia from the command line.
