Disabling macOS Secure boot and SIP for T2 Systems 

Customers working with Mac platforms manufactured in 2018 or later that feature a T2 security chip, will need to disable the Secure Boot in order to load drivers for third party devices. 

In addition, macOS 10.13x and earlier may require that SIP (System Integrity Protection) be disabled. If enabled, older versions of macOS may prevent the NVMe drivers from loading.

HighPoint products affected by this requirement include our NVMe RAID product lines (SSD7100 and SSD7500 Series RAID Controllers and SSD6540 series NVMe RAID Enclosures), RocketRAID series controllers (RR4500, RR3700, RR2800, RR2700, RR800, RR600 series), and RocketStor 6400 series External RAID Enclosures.

Disabling Secure Boot

In order to use these products with T2 systems, Secure Boot must be disabled. To disable this feature select "No Security" from the Startup Security Utility interface. You can access this menu by pressing the Command (⌘)-R keys after the Apple logo first appears during the boot-up process.

Additional instructions are available from Apple’s website:
