I just installed Hackintosh and had a couple questions..

I used this guide to install High Sierra:

One of the last steps was to add an "EFI" folder to my Desktop, and then merge it into my disc via Clover.

is it safe for me to delete the Clover application and the EFI folder on my desktop now?

also, on boot, do I have to go through Clovers "Boot Mac OS" everytime I boot up? is it possible to automatically boot directly into the OS?

and besides checking my Wifi, USB slots, and Audio, should I troubleshoot and check anything else?

I don't plan on using iMessage, iTunes or anything that involves my Apple account.
