    OSX 10.9 Mavericks on MBP 13" Early-2015?

    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...
