Fasttrack Pro USB, El Capitan working!

[jonathan Levin]

I hear everyones frustration. I spent the last few hours going over all the steps and ideas terminal commands and others.

Here is what got my FT USB working with El Cap 10.11.2: I simply deleted both the drivers I had installed, 1.9.4 and 1.9.5. One was in one location and the other was in a folder called Software which I could not find.

I am on a mid 2010 Mac Pro quad-core.

How I did this was first menu About this Mac>System Report>Extensions. At this point I saw nothing in there, but it took about a minute for these to show up, at least for me. If they don't all show up which also happen to me, go to File>Refresh Information.

I then found the two drivers. You will see something that says Location in the description. Highlight and copy that url. Then from the finder Menu, Go>Go To Folder...>then paste that url. Click OK. Window appears with that driver. Move to trash, but will ask for Admin password.

I repeated this with the second driver that was installed. I then deleted the System PreferencePane of the M-Audio fasttrack pro using method described above.

I then restarted computer. Went into System Preferences>Sound, and just like magic, my Fasttrack was listed in both the input and output and as I write this I am listening to Art Pepper.

Whether or not this remains stable is a whole other thing. It is odd that it works without any driver. As others have pointed out, you no longer have access to M-Audio prefs, but at least I am able to get music from my nice powered speaker system.

Hop this helps.

Thank you for the info. I tried the same thing with my Mbox 3 Mini on a Macbook Air. My system now recognizes the Mbox, and I am able to play audio through it. I am also able to use it to record and playback in Garageband.

Pro Tools is a different story. I am on version 11.3.1. PT recognizes the Mbox and allows me to select it as a hardware interface, but I am not able to open any of my saved sessions. When I go to open a session, I get an error message that says: "The current playback engine does not support a sample rate of 48 kHz" I get the same error for 44.1 kHz.

I am also not able to create a new session. I get this error message when I try to do that: "Could not create a new document because Assertion in "/Volumes/Development/151228/ProTools/DFW/MacBuild/../Views/UMenu.MacOS.mm", line 1549."

I did not see anything like this when I tried - "I then found the two drivers. You will see something that says Location in the description. Highlight and copy that url. Then from the finder Menu, Go>Go To Folder...>then paste that url."
I did this and found a very long list of Extension in a scrollable panel. 99% are Apple extensions. There are only a few third-party extension sets - HP Printer and PACE support. I am surprised not to see my MBox listed there even though it shows up under System Preferences which verifies that it is installed. Basically I don't see any I/O Box drivers to throw away.
Disclosure - my computer is only two weeks old (rMPB Pro) so the only audio driver I manually installed is latest MBox3 driver.

What, exactly did you toss?

[Brad Gillie]

This is where I found one of mine.

/Library/Extensions/AvidMboxMini.kext

I no longer have the location for the other file or the preferences saved in my history. Everything was listed under Avid. When you find it under the Extensions and Preference Panes menus, click on the file, and that is where you will see the location.

[Ormond]

Yes, the MBox .kext file is in my library/extensions and xbox prefPane is where you said it would be as well - are you saying I should put both n the trash and then try to run my MBox?

[Brad Gillie]

I did what the OP said. I moved all the files to the Trash, then emptied it and restarted my Mac.

Just curious, I read that the Fast Track Pro was (UNTESTED) for Pro Tools 12, when I make my Fast Track Pro the main interface the audio will come out from my headset which is a good thing....but then i can't get my Blue Baby Bottle Mic (Connected to the Fast Track Pro) won't respond and i can't arm any tracks because of the input error....is this because the fast track pro isn't compatible yet??? should i just go get something that is compatible like Fast Track SOLO???? I'm asking because for the longest I've used the fast track pro with my Pro Tools SE & have never had any issues until i went from the old OS X to El Captain...thats when all my problems occurred.

Hi guys. Just install drivers 1.9.3. They work on el capitan.

If you are searching for a manual uninstall of the Fasttrack Pro in 10.12 Sierra these are the files up to be deleted, and the addresses were to search them:

./System/Library/Extensions/M-AudioFastTrackPro.kext
./System/Library/Extensions/M-AudioFastTrackPro.kext/Contents/MacOS/M-AudioFastTrackPro

./Library/Extensions/M-AudioFastTrackPro.kext
./Library/Extensions/M-AudioFastTrackPro.kext/Contents/MacOS/M-AudioFastTrackPro

./Library/LaunchAgents/com.m-audio.fasttrackpro.helper.plist

./Library/PreferencePanes/M-AudioFastTrackPro.prefPane
./Library/PreferencePanes/M-AudioFastTrackPro.prefPane/Contents/MacOS/M-AudioFastTrackPro

./private/var/db/BootCaches/FA059394-A860-4A33-A2FF-611426051B7B/app.com.avid.usb.fasttrackpro.firmwareupdater.play list

./Users/jaco/Library/Saved Application State/com.avid.usb.fasttrackpro.firmwareupdater.savedSta te
./Users/Shared/Library/Preferences/com.maudio.usb.fasttrackpro.driver.plist

Btw this is the command to search inside your Mac. Try it in various combination, avoid to trash important file system or system audio kext.

sudo find . -iname "*fasttrackpro*" -print

In Sierra OS Console, this is Not a Case sensitive search. May be in other OS.
for more info on this command just refer to THIS POST.

Your procedure is very good for getting rid of garbage. Now I'll say what I did to make my FT Pro working on my Yosemite:
1. Plugged FT Pro on a Windows 10 machine;
2. Installed the last Windows driver, which supports up to Windows 8.1. After the installation, it will offer the firmware updated. I accepted it, but don't know if it's mandatory. Note that the firmware update tool contained inside the Mac .dmg archive never find the interface, but the Windows utility works.
3. Made the procedure described above to remove any remaining garbage from previous drivers.
4. Disabled kext signing on Yosemite;
5. Installed 1.9.5 driver. Done. Now you have your always-not-so-good interface working again. If it doesn't work, try restarting the interface while not playing any audio playing (device not streaming anything), otherwise your system can hang.
