Re: What is now the status of 424 PCIE card in a Thunderbolt enclosure

In the 13 years since the 424 was discontinued, no one has been successful making the 424 work in any external box connected to a Mac. Until 2020, all were Intel machines. MOTU would have to make a version of the 424 with updatable firmware and was unwilling to do so. To be clear, firmware incompatibility was always the issue — UAD cracked that nut a couple years later but only their cards with updatable firmware benefitted.erodrigues wrote: ↑Thu May 15, 2025 11:03 amI think that the key element here is the original PCIe driver for macOS which I suspect it is developed for Intel x86/x64 Intel CPUs therefore I believe that it should work on Intel based Mac but guaranteed not to work on Apple Silicon CPUs.
So pardon me if I believe that you are incorrect. I have an open mind in case someone ever does it.
In the meantime, there are many Windows machines where these do work, even if MOTU no longer supports it.
