IAC driver is dimmed/greyed out

Hi,

How come IAC driver is dimmed. I restarted the MacBook Pro, it did not help. I have a notation software ( Finale) sending MIDI events via a instrument on a staff to IAC driver input port ( channel 1), I am using third party MIDI monitor software, however, there are no activities on IAC driver.

What should I do please?

iMac 21.5", macOS 10.14

Logic Pro won't open after Ventura update: stalls on scanning audio unit plugins this is INSANELY frustrating. I recently got a brand new M2 MacBook Air, and made the mistake of updating to ventura when it was released. Now, i cannot open Logic Pro. Logic will spend a long time scanning audio units and then when I restart it will hang on "updating information about audio unit plugins". It will not complete in any amount of time. I have tried EVERY solution suggested online. Removing all plugins from the plugin folder allows Logic to restart, but when replacing the plugins it once again hangs on rescanning them. Deleting the plugin cache seems to get you a little farther, since you can see the actual progress and arrive at the 'Incompatible Audio Units Found' pop up. This pop up tells you that there incompatible audio units and offers two buttons: 'Continue' and 'Start Plug-In Manager'. this is the most infurating part: clicking on either of those two buttons results in ANOTHER hang. The beachball immediately appears and no amount of time will allow Logic to start. This is apple's OWN software on it's OWN update! It's so insane that with a brand new machine and the most recent OS i can't open the one program that i most use on a mac! I hate having to spend weeks googling and trying every tentative solution. If Logic identifies the incompatible units, WHY CAN'T IT DISABLE THEM AND START LOGIC PRO!!!

USB disconnect on restart MacOS Ventura I've asked about a similar situation before to no response, I'm very curious if others have a similar situation and how I can solve this problem. Since the Ventura update, the USB ports on my monitor haven't been working, or have been very inconsistent. I ran my Mac Studio with various items plugged in to USB ports of my Asus monitors. And things worked fine for months. I upgraded to Ventura and since then, it has been a huge problem. Suddenly, the ports I used for months no longer worked with the same items plugged in. I resorted to plugging things directly into the Mac Studio and unplugging when I didn't need them. One day in desperation, I started switching all the ports around and found that certain peripherals worked in the monitor USB (Scarlett 2i, Rode USB mic), but things like my Logitech webcam won't. So I found a work around. Well, now I have added more items. Recently, a StreamDeck+. I had it plugged directly into the monitor USB. It has worked for two weeks, no problems. Today, I restarted my Mac Studio because I installed something that required it. Well, on restart, my StreamDeck+ no longer works in the port it was previously using. I recently added a thunderbolt hub with an NVME, which is on a separate Thunderbolt port. I had to move the StreamDeck+ to one of those ports to get it to work. Even though prior to restart they worked individually. Is there a setting I'm missing? My Mac doesn't give me any kind of approval in Privacy & Security. I just don't understand what causes the USB/port access to change between a restart. It has me almost terrified to restart because who knows what else will go wrong?

EtreCheck is a simple little app to display the important details of your system configuration and allow you to copy that information to the Clipboard. It is meant to be used with Apple Support Communities to help people help you with your Mac.

Workable but harder for me to work with...the Note tool on the bottom of this editor's toolbar, as shown in the image, to copy and paste the output from EtreCheck.

I think this is normal! Maybe due to GUI in dark mode.
