High Sierra 10.13.2 cannot find my audio device

I bought the Focusrite Scarlet 2i4 because 10.13.2 broke functionality of my M-Audio Fast Track Pro, and it has been working fine
- no drivers or apps necessary.

thelostsoulman: did your Scarlett Solo work work in 10.13.2? According to Focusrite, the Scarlett line is compatible with High Sierra:

https://support.focusrite.com/hc/en-gb/articles/115005073725-Focusrite-product-c ompatibility-with-macOS-10-13-High-Sierra

Meaning it’s an actively sold and supported device, so I’d be shocked to learn that 10.13.3 broke it.

Side note: in what app are you looking at Audio MIDI Setup > Audio Devices?

I just installed macOS High Sierra 10.13.4 and my Fast Track Pro that hasn't worked since december started working again.

Confirmed. Issue is solved in 10.13.4. Fast track pro is working again.🙂🙂

Hi,Jack.

On Latest update of High Sierra,10.13.4., I found Fast track pro selectable on "sound preference".

and no problem to play iTunes.

My machine is MBP13'2012 Mid.

Please try!

If you update to 10.13.4 it will work again, but DO NOT upgrade to 10.13.5.

So the Apple Engineering escalation came back as a negative. They say it's not their fault, and it's over to the third party supplier - even though the FastTrack Pro worked perfectly well on 10.13.1 with the default Mac USB audio driver. Really angry about this, because it's a perfectly good sound card which still works on my 10.13.1 MacBook Pro. The manager I spoke to in Support said that it's possible that 10.13.3 may resolve this (but from others in this chain, it does seem the current 10.13.3 beta does not fix this). I've provided feedback on this, and suggest you guys all do the same. Product Feedback - Apple --> macOS Apps --> macOS.

Hey Man,

I had the same problem with my Fast Track Pro. I had the Sierra High 10.13.1 installer and I simply re-installed this version. By doing this I just downgraded my OSX version from .2 to .1 and upon restarting I got my card working again.

Hope that you still have the installation somewhere around because if you do then this is your solution!

Cheers,

Herc

so i just learned that fast track pros where been supported by avid instead of m-audio and apparently they will supported it until 2/11/18 (as shown in the screenshot i've attached, the last date is the end of support date)... i cant get in touch the support center because im in south america, but could any of you guys try contacting then, see what they say, heres the link of that page also. http://avid.force.com/pkb/articles/faq/End-of-support-dates

Hi friends, I've got a lot of help before, now it's time to give it back.... ;-)

I found a (temporary) solution for the issue.....!!

I copied some files of the mbox-driver (with has been updated for sierra) into the 1.9.5. driver of my fast tracks pro files, tryied some combinations..... and magic!!!! It works, it works for recording, track values etc etc.... I attach my patched files with this instruction:

1. install the included mbox-driver

2. install the included fasttracks pro-driver

3. exchange like written on the folder

4. delete like written on the folder

Good luck!! - Minicus

The workaround posted in this discussion didn't fix things for me at all. I tried numerous workarounds to no avail.

Good news: 🙂🙂

Mac OS 10.13.4 beta version 2 seems to fix this issue so just hold out for a few weeks until the version is finalised and released to everyone or install the public beta, info on public beta available here: https://beta.apple.com/sp/betaprogram/

Hope this helps 🙂

Sharing again for the sake of other people that might be plodding through the same problems and potential solutions.

I think that your right hand screen shot is not from the systems report but rather from UTILITIES > Audio MIDI Set up.

There I found that Fast Track Pro was greyed-out, so I highlighted the icon, hit the minus sign at the bottom to delete it,

disconnected the unit from the iMac, then reconnected it, and the iMac immediately restored a live icon.It is now working (under High Sierra 10.13.6).

In the update, the link between the unit and audio midi setup simply got "lost", it would seem.

So your principle was right; let the iMac build/restore the link ... but the I think the easier way to do it (rather than looking for drivers in God knows which library and uninstalling them) is via UTILITIES > Audio MIDI Set up.

Hello guys!

I had the same problem, and after update to MacOs Sierra 10.13.4 my M-Audio Fast Track is working again.

I think it might be an apple issue. Avid only provided drivers up to 10.10, so they haven't done anything with it in a while (as much as I wish they did). From what I understand, the fast track pro is a class-compliant audio device (http://avid.force.com/pkb/articles/en_US/How_To/en399803) and has only been working since 10.11 with Apple's built in class compliant usb audio driver. The driver gives access to the s/pdif i/o and outputs 3 & 4.

The only question is, did apple chance something to make their drivers less "class compliant" or was the fast track pro's implementation not very class compliant to begin with?

I have restored my system to the previous OS. It took all day, but it was worth it. I am using Yosemite again. When I bought my Mac Mini, I was advised by the sales person to buy an external disk and run Time Machine. It was good advise, since the restore went smoothly using my Time Machine backup. It is such a relief to have it functioning again.

Thanks for the suggestions.
