Hello @RehabMan I am in process of making a Hackintosh on my Lenovo T440 laptop, with guide by @Sniki I have created my USB Installer of High Sierra, using createinstallmedia method as described in your post. ====== [Guide] Booting the OS X installer on LAPTOPS with Clover ====== I have successfully created the USB installer, but once I install macOS on my laptop, it said "the installer is corrupted and cannot be made to install". I made 2 USB Installer, one with my MBP running 10.8.5 to produce a 10.13.3 installer, and another one with my Hackintosh running 10.13.3 to produce a 10.13.15 installer. Both result in the same error. What did I do wrong here? Thanks.
