2017 Macbook - Not able to connect to 4k monitor via USB C port I'm trying to connect my 2017 MacBook to a Samsung M8 Monitor however the monitor is not able to detect the MacBook via the USB C port input. Since I'm not sure if the issue is with the monitor or the MacBook, I did the following steps to make sure the monitor was functional. The USB C port on the M8 Monitor is able to detect and charge my dell latitude laptop and Samsung galaxy tab s7+ without any issues. I tried using a different USB C cable but still can't connect to the MacBook. The other peripherals connect fine with the different USB C cable. The MacBook is able to connect to the monitor via HDMI input. I used a USB C hub for the MacBook and connected the HDMI to the USB C hub. Ideally, I would prefer using the USB C cable for a cleaner setup. I noticed a weird behavior when I power down the MacBook completely, connect the monitor's USB C cable and turn on the MacBook, the MacBook will charge but still not display on the monitor. However when I disconnect and reconnect the USB C cable while the MacBook is turned on, the MacBook does not charge or connect to the monitor. I tired to reset the MacBook PRAM and SMC but it didn't help. The MacBook is currently running the latest Ventura OS.

MacOS Ventura - External Monitor disconnect I just updated to macOs Ventura, and my external monitor ( Samsung C43J890) Keeps disconnecting every couple of minutes. It is currently connected via USB-C. Was working fine prior to updating to Ventura, so my assumption is that it is related to the OS updated. Mac Book Pro M1Max.

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?

Csmert,

Let's use the steps from this resource to create a new user account to see if those behaviors persist when logged into a new user account: Change Users & Groups settings on Mac - Apple Support

That will help to further isolate this behavior to either a system-wide or user-specific conflict.

Let us know your results, and we'll keep moving forward from there.
