Usb C hub not working on MacOS Ventura

Macs without a built in display don’t show that option – I think that is the option that’s on by default. I have a M1 Mac Mini that doesn’t show this option; my M2 MacBook Air does have this option.

The connectivity issues to devices through USB hubs does not away when setting this setting on my M2. Both my M2 and M1 Macs experience this issue constantly.

This started happening on Ventura (13.0) for me with a Lacie 2big Thunderbolt 3 Dock in JBOD mode. The 2big is connected via a high quality Thunderbolt 3 cable and (at the moment) has 2 disks, and daisy chains a TimeMachine and a DisplayPort monitor. I updated to macOS 13.1 and it was not improved. I use a 2020 27-inch iMac. I've never had any issues with this setup until recently. Strangely, the issue for me seems to have begun after I returned from a couple weeks of travel. When I left, I shut down the iMac, and powered off all my external gear, and unplugged the Lacie 2big. When I returned, I powered up all the accessories, and started the iMac. Now, whenever the machine goes to sleep, I'll return to messages about "Disk not ejected properly" for both the drives in the 2big. I've also noticed that light on the front of the 2big seems to blink on/off when the iMac is asleep, which it didn't do before. I'm assuming the amount of those blinks I see corresponds roughly with how many (lots) of the "Disk not ejected properly" notifications I get. Also worth noting, I use a couple Universal Audio Apollo Thunderbolt audio interfaces. Since returning, they also have a greater incidence of misbehaving when the iMac wakes from sleep. They almost always seem to require being physically disconnected from the iMac, and sometimes each need to be power cycled before they are able to interact with the controller app in macOS again. Until that happens the app is frozen and the interfaces are unresponsive.

This isn’t a hardware issue or we all wouldn’t have developed this problem with a software update.

It’s worth noting I didn’t comment on whether it was a hardware or a software issue. You simply made that assumption. Do you have some reason to believe Apple can’t run diagnostics on both?

Welp. Misread! Apologies friend.

I do strongly agree with you that it’s useful for Apple to be made aware of the problem. The more people who report it directly to them, the more likely they are to allocate the resources to determine what the actual cause of the problem is.

Entirely possible that it's also user error, but this may be the clunkiest, most Microsofty discussion format I've used. With apologies for confusing strings, I think I got a separate DM-email from you (Cineman18) asking for link to my comment. I was replying to comment by shyism on November 8th. I'd copy it here but copy/past doesn't seem to work. Hope that person's suggestion, which helped me, helps you too.

Not sure how similar this is, but I'm pushing some limits -

I have a very handy Plugable USB-C 4K which is

POWERING:

• 2021 MacBook Pro M1
• Scarlett Focusrite 2i2

Several devices from USB-A and USB-C via many ports - two of which are loose Lightning cables I use for iPads, iPhones, etc. One is USB-A and one is USB-C (this is important)

CONNECTING:

• Samsung Odyssey G9
• Samsung T55 Monitor #1
• Samsung T55 Monitor #2

This setup has worked great for the last year. As of Ventura, it is being very finicky with the displays and, while it says it's charging my iPad and iPhones via the lightning cables mentioned above, they are definitely not charging. USB-A and USB-C have the same issues.

I'll acknowledge that this setup is a little ridiculous :)

Just curious if anyone has tried extra monitors as I have, using the Plugable USB-C 4k. Honestly, with the help of Display Maid, this setup, for my dev work, is INCREDIBLE.

Unfortunately, that setting is not showing for my Intel based Mac Mini. However, it does show up for my M1 based MacBook Pro.

Do you know if there is away to set that using a terminal command?

This setting is only available on Mac Notebooks with  Apple silicon.

It does not apply to Intel Macs.

Sorry, but this seems not to be the case. I've just upgraded my Mac Book Pro 13' (2017) to Ventura 13.2 and still cannot connect to USB-C hub attached external disks. Either they are not visible at all, or when trying to connect for the first time after rebooting it shows up on the desktop very shortly and then an error message is displayed 'Disk not Ejected Properly', and then it's diconnected. Then there's no chance to reconnect by unplugging/ replugging the USB device. Great job Apple !

Hm. I just finally upgraded to Monterrey (13.2.1, 2017 15" Intel MB Pro) just now, and all of my USB devices have stopped working (keyboard and HDMI through an Apple USB-C Multiport adapter, and Time Machine drive via direct USB-C to USB-C cable).

May end up going to the Apple Store for this one. 🙁

Having the exact issue right now. I even went and got a new Belkin hub and tried the powered one and they don't work. I think at this point apple is just letting just know for the future we won't be able to use other products on their devices.

I was online trying to decide on a non-Apple Monitor (price is my reason) to use with my MBP M1 14" 2021 and found two that look interesting. In reading the reviews I found several low ratings because the USB-C would not allow the monitor to work with the MBP. One person responded after talking with Apple Support and Dell for 2 hours. He reports  that "according to both manufacturers, Ventura, 13.2 operating system will not allow the Dell (and many others) to connect via USB C. According to both, there is some safety feature that Apple put in their latest software to protect it from using other manufacturers' USB-C monitors. In particular, Apple mentioned, Dell, LG, BenQ. "

I am wondering if anyone affiliated with Apple knows if there is any truth to this statement. People can say anything on the internet and I think that much of the time, people are being honest and trying to help. And there are certainly those who lie and enjoy stirring up trouble. I have no way to know about the validity of this person's statement and I am not endorsing it to this Community. It occurred to me to come here and ask more experienced and knowledgeable users what the truth is.

I really need a new monitor as I'm using my MBP screen at the moment and my eyes are begging me for a 27" monitor :-)

Thank you for any help and/or answers you have to the claim I shared or where else I can find out. I don't want to buy one, of course, that in the end won't work.

Only the best,

Michelle

There are lots of knowledgeable and experienced people here. However, they will not be Apple employees. This is a user-to-user support forum and Apple's participation is limited. If you want to get the answer directly from Apple, you'll need to contact them directly. You can start with the Support link at the bottom left of every page of these forums.

Perform SMC reset Intel only.

On an Intel you can't find Preferences > Privacy & Security, "Allow accessories to connect".

You can search with Spotlight... "Acces".

But you can click on that and go there but it won't be visible.

I'm on Ventura 13.3.1, MacBook air, i5, 2020. I couldn't charge my Mac.
