Hello,
That would be the last version of macOS to support .kext drivers, this would be 10.15, but there is an extra notarization step for .kext drivers required by Apple in 10.15, that is not noted in that document. As such it would be safe to assume these instructions work up for drivers up till macOS 10.14.

Hi "FTDI Community" / moderator,
I've been in contact with @scottmiller regarding his difficulty adjusting the macOS 11 FTDI 'latency' setting. (macOS 11 is required for Apple hardware using the new M1 CPU.) For our Windows customers, this is extremely easy: they just bring up the Windows driver control panel, and type in the new Latency value. In this case '1' ms is the Latency value we need for optimum packet latency with the OpenBCI Cyton product.
What we are requesting: is a similarly easy way to do this on macOS 11. That should not require modifying Info.plist files, or signing a driver. It should be an external file that you look for, upon driver loading time. This would have fields similar to a .plist, for adjusting values like are possible on Windows. But it would not have to be a .plist, could even be something simple like one line per adjustment: "variablename value".
Can you give us a timeline for when FTDI will release this macOS 11 compatible driver with adjustable settings? The lack of this is causing great difficulty with our Mac customers.
Thanks,
