( os x 10.11 El capitan ) interface (tascam stop working?

What is tascam? An app? A website? or ?

Is there software involved? And, is the product compatible with El Capitan? I'd suggest that you check with the device manufacturer support.

Sorry, but if the device and/or its software is not compatible, I don't know if there is anything that can be done. I can't help since I am not familiar with that - maybe someone else is. I'd also find their support page and post a question there. Maybe another user can help.

I have the Tascam US 1800 myself and I just upgraded to El Capitan and won't work either. I am thinking of restoring back to Yosemite at least until Tascam figures out and gets the drivers on the website for download. The model is discontinued so not sure if they will have an updated driver, however since it is a very popular model they probably will have a driver available soon. I am going to check in with them this week.

I have the Tascam US-144 it is now usless with El Capitan. even plugging it into the Mac USB port gives me the pinwheel constantly. Slows everything down. When unplugged it goes back to normal. This also means no access to Garageband

Hi guys.

I have a US-1641, the model that pre-dates the 1800, and I have the same issue. Logic sees it but will not work at all with it selected as a source. I've also had many hangs, spins, and kernel panics while the device is attached to my machine since upgrading. All symptoms of an incompatible driver. Tascam's site only shows drivers for these devices running OS's as late as Yosemite. I hope they eventually update them.

But for now I'm in the process of wiping my machine and re-installing Yosemite. I'd suggest you guys do the same. Oh, and of course, backup first.

I've got the US-600, same problem as you. I had do remove the drivers as well becase they seem to slow down my machine even with audio card not plugged in. A couple of days ago I've noticed something intereseting, after 10.11.1 update: Native Instruments plugins (that weren't working after 10.11 update) now are ok, and plugging the US-600 dont's slow down anymore the system. Unfortunately now there's no driver installed and (as said in v.3.00 drivers release notes) they cannot be re-installed... Someone knows which files I have to restore to Library or other system folders to try if the audio card is working now?

UPDATE:

I've managed to restore the drivers/configuration files in original positions, now the device is available again in Tascam Control Panel and in audio settings.

Unfortunately, no changes in behaviour: when plugged in the device is still not working, it emits only clicks" and system is slowed down.

At this point, I fear the only way to solve the issue is waiting for a new driver update, or replace the audio card :/ I hope they will release the driver as soon as possible, last year the first beta was released in January (3 months after the OSX update... 😟 )

Tascam has now made a driver for El Capitain for several of their audio interfaces including the US-1800. Looks like they are starting to resolve this issue. Take a look at their website.

Very good news, thanks!! So I'm waiting for my US-600 driver, I hope they release it soon.

I contacted Tascam and got this response:

As the official version of El Capitan was recently released, we are in the process of testing the compatibility of various models. Once we have the final results (hopefully by the end of the month), they will be posted in the NEWS section of the website.

If you use Time Machine to back up your Mac, you do have the ability to revert back to your prior OS if necessary.. Contact Apple for further details.

Thank you for your interest in TASCAM products.

Its same ocour whit M-Audio Legacy interface. To resolve make this:

Turning Off Rootless System Integrity Protection in OS X El Capitan 10.11 +

Again, the vast majority of Mac users should not disable rootless. Disabling rootless is aimed exclusively at advanced Mac users. Do so at your own risk, this is not specifically recommended.

1. Reboot the Mac and hold down Command + R keys simultaneously after you hear the startup chime, this will boot OS X into Recovery Mode
2. When the “OS X Utilities” screen appears, pull down the ‘Utilities’ menu at the top of the screen instead, and choose “Terminal”
3. Type the following command into the terminal then hit return:

4. csrutil disable; reboot

5. You’ll see a message saying that System Integrity Protection has been disabled and the Mac needs to restart for changes to take effect, and the Mac will then reboot itself automatically, just let it boot up as normal
