[everything is tested on my L322x]
actually there is a HOW-TO.txt on my website
don't pressure the info too much, just read and do as it tell [it's splitted into big steps but you need to know something about clover and hackintosh, gpt, etc]
I will try to update the latest version tonight as I'm selling my XPS in like 5hours [sleep is kinda ok - I explained why it breaks]
I don't have time to implement on-the-fly patching for the USB 3.0 [i've just done the _OSC method], so you will need the GenericUSB
my method uses no aditional 'stuff', just vanilla and a copy>paste of the files I gathered and modified explicity for Dell XPS 13 L321x and L322x]
I will 'sleep/hibernate' the support on my site at least for a while [taking a break], maybe I'll return and if someone is ok to be the guinea pig, maybe I'll do some blind moding on the CLOVER config for the XPS [I will explain you what you need to do, all you need is to have a USB flash drive] - you will have the latest files but may be unstable [no chance of bricking the device so relax]
[no kids please]you're interested in geting this better ? then prepare to test and contact me by my website [contact > report bug] - I'll be patient with you and you'll definitly learn, understand the vanilla stuff of a hackintosher but you need to really want this [a lot of reading and hard work, not just to understand what it's already available, but I'll teach you how to understand the binary patch] - I'm taking up to two people [/no kids please]
