Check my comment regarding Sabrent Rocket from a couple of weeks back.
(Don't buy new Sabrent Rocket 2TB)
As for installation guide to install NVMeFix. the following might not be entirely accurate.
1. diable SIP
in Recovery/USB installer, etc: open utilities->Terminal
in there: csrutil disable.
2. download latest NVMeFix kext from :
https://github.com/acidanthera/NVMeFix/releases
3. download latest LiLu kext from :
https://github.com/acidanthera/Lilu/releases/
4. you would want to copy to NVMeFix and Lilu kext to either:
/System/Library/Extensions or /Library/Extensions
if you are on Catalina you would need to jump through more hoops. before you copy
do : sudo mount -uw /
5. you would want to change the owner group to match other files
sudo chown -R root:wheel /System/Library/Extensions/<YOURKEXTHERE>/
6. you might have to set boot-arg to boot unsigned kext (not sure if its signed)
in terminal do:
sudo nvram boot-args=debug=0x144
Ask around. Some might have simpler way of doing it (usually kext is installed using hackintoshtool or w/e as its easier)
