macOS driver for the ATTO Tech SCSI Host Adapters:
- ATTO ExpressPCI UL4S
- ATTO ExpressPCI UL4D
- ATTO ExpressPCI UL5D
- ATTO ExpressPCI UL5D LP
===============================================
ATTO Tech no longer has this driver for public download. ATTO considers the UL5D obsolete thus wil nit support it. That leaves us to be 'Renegades'.
The driver is provided here.
Instructions to install the driver were created based on Ventura.
Most likely is required between Mojave to Ventura, prior to Mojave it most likely installs direct from the package.
================================================
sudo nvram boot-args="kext-dev-mode=1"
Reboot to Recovery, Launch Terminal run:
csrutil disable
Check status: csrutil status
Install ATTOExpressPCI4.kext with Hackintool, approve it in System Settings and reboot.
