Hi, I am here to ask that is there any way of installing OSX 10.9 on an Early-2015 MBP? To this day I still pretty much don't like how macOS looks and some compatibility issues with older versions, I tried using a bootable USB installer but it doesn't work it shows up a blocked sign or something like that, do does anyone in this community knows how to do that? thanks.
 
Some techy here might correct me, but the earliest version you can instal on a Mac is the version it first shipped with/got released alongside with.
 
it is correct but is there some sort of bypassing the kernel or checking the compatibility to install it?
