I've created as USB-C install drive to do a clean install. With the new 2018 MBP's with the T2 chip, will holding down Option to install via the USB install drive still work?.....Or do I need to do Option + ⌘ +R to install?

[doublepost=1543763153][/doublepost]I keep the option key pressed, it lets me choose the boot disk, then it asks again for the wifi password and I get back to the same "update" message. Before my agreement for the update the wifi is conected. Any chance you might help me on this one? Thank you.If you want to clean install from the thumb drive, boot into Recovery (Command+R). In the menu bar, click Utilities > Startup Security Utility. Select an Admin account and enter the password for it. Next, under ‘External Boot’ select ‘Allow booting from external media’. Close out of the utility and restart the computer holding the ‘Option’ key.
Select the thumb drive from the boot select menu. When it boots, it’ll say that a ‘Software Update is required to use this startup disk’. Make sure you’re connected to Wi-Fi on the top right, then select ‘Download’. Let it download, and it’ll automatically reboot. On the SECOND reboot, hold down ‘Option’ and select the install disk again. After showing and taking away the Apple logo 2-3 times, you’ll be greeted by the ‘macOS Utilities’ screen. Go crazy.
Note: the thumb drive has to be created using an App Store downloaded copy of Mojave and Terminal.
