Hello everyone,
UPDATE - October 14, 2025
Support for macOS 26 has been added with version V4.0.4b.
Since Apple has already declared that the Kernel Extension will be discontinued in future macOS, we decided to release a public beta of the Yamaha Steinberg USB driver.
The version V4.0.4b is available only on the Steinberg forum exclusively.
This new driver uses the Driver Extension (System Extension) and not the older Kernel Extension solution anymore. It will prevent the “Legacy System Extension” warning message from showing.
Supported OS: macOS 13, macOS 14, macOS 15, macOS 26
Supported Platform: Apple silicon (no Intel CPU support)
Supported Models:
AXR4U
IXO12/IXO22
UR22C/UR44C/UR816C/UR24C
UR12/UR22/UR22mkII/UR242/UR44/UR28M/UR824
UR-RT2/UR-RT4
It is no longer necessary to change security settings from recovery mode when installing drivers on a Mac with Apple silicon but allowing the driver in “Security & Privacy” is still required.
Please find here the link to the driver, the installation guide and the release notes.
Please be aware that installing this driver is for technical evaluation only and the installation is the responsibility of the customer.
