Yes, we'll install the beta at some point and test. However, the only Mac I was able to confirm the bugs on is not supported by Mojave. So, bottom line is that we may no longer have the ability to duplicate the bugs even if they persists in Mojave. Anyone who's testing Mojave would give us valuable insight into these bugs.


Jay, I have Mojave dev beta on a couple laptops, but neither are related to my Indigo setup. Is there still some testing I could do for you that would help out? The beta is running smooth enough now that I may put it on my general use Mini soon, but that is also not related to my Indigo setup at all. But I could periodically shut down my Indigo server and move hardware around for tests, if it would help.

Can you confirm which PowerLinc you're using? You mention a 2412U and a 2414U. The latter doesn't use the FTDI driver so if it doesn't work that would be a different issue.

My bad; that was a typo.
My Mojave system has a 2412U, a W800RF32 and an iButton 1-wire adapter connected. All 3 USB devices were completely non-functional (again) after the 10.13.6 update. No amount of reseating or restarting or USB hub nonsense has any effect.
Deleting the AppleUSBFTDI driver is the only solution I've found.


I just reread your reply and I'm confused: you say your Mojave system but later you say 10.13.6. So, my question is have you experienced the issue with the Mojave beta?

Thanks for the offer. What we'd need to know is 1) if either one currently has the driver issue when running 10.13.x, and then 2) if the same issue occurs after you upgrade that system to Mojave. That's a non-trivial amount of work so you may not want to undertake the testing (and I totally understand).

Grr! I keep doing that. It was remote desktop to my Mojave system, and I accidentally clicked on the "About this Mac" for my local machine instead of the remote one. :oops:
My Indigo server is running MacOS version 10.14 Beta (18A347e).
When I was running High Sierra, only the 2412U would stop responding after a random amount of time. The W800RF32 and 1-wire adapter would still continue to function. A simple restart fixed it. Once I deleted the AppleUSBFTDI.kext the problem never popped up..
On my Mojave system, it's a different story. All 3 of my USB serial devices completely fail using the Apple driver. If I delete AppleUSBFTDI.kext everything works great (and hasn't randomly disconnected either).

Dang - sounds like maybe it's actually getting worse. Sigh.

Thanks for the report. One final question: what is the exact model of your Indigo Server Mac?

Re: macOS High Sierra (10.13) FTDI Driver Bug Workaround

Mac Pro (early 2009). Firmware upgraded to MacPro5,1
Motherboard USB ports and generic USB 3.0 PCIe ports have same results.
Is there anything else I can do to help troubleshoot?

Odd, Apple claims that only the 2010+ Mac Pros can run Mojave...

[EDIT] Never mind, I see you hacked the firmware... ;)

Not that I expected any change, but I just installed the 10.14 Beta (18A353d) update and all my serial ports went stupid again.

Did you provide a bug report with Apple?
