The reason why many drivers are not working anymore:Īpple extended the "kext signing" to drivers and only drivers from trusted sources are loaded by the El Capitan kernel, no bypass option here (like for applications in the control panel). Signed by:ĝeveloper ID Application: Avid Technology Inc (4UYUA773XD), Developer ID Certification Authority, Apple Root CA Get Info String: M-Audio Fast Track Pro USB 1.9.5, Copyright © 2013 Avid Technology, Inc.

The 1.9.5 (Fast_Track_Pro_Driver_1_9_5_Mac_83635.dmg) installer installs two different kexts:īundle ID: .driver Im not sure if its just that both drivers have to be the same in each folder, can't tell you what version will definitely work, but I downloaded latest from avid if you have no idea what I'm talking about

apparently even works without setting kext permissions. You may not have a driver to replace in /Library/Extensionsģrd weird thing. I guess it must be old driver install left it in there. It seems I had old version of the driver in /Library/Extensions, which is the second weird thing because the latest installer doesn't put anything there. Before one was loaded and one was not, but there was version mismatch. System/Library/Extensions (Backup first!)įirst weird thing is that System Information > Software > Extensions shows that I have two kexts both unsigned and apparently unloaded. I found how to get it working on el capitan
