Mac Ventura file sharing stopped working

Hi DazzAU,

A great first step in isolating software-based concerns on your Mac is to test the behavior in safe mode. How to use safe mode on your Mac outlines the specific to perform that test depending on your model.

Once completed, that article offers further steps based up on the results to further troubleshoot potential causes for for the noted behavior.

DazzAU,

Is the Mac's built-in Firewall currently enabled? If so, try disabling this temporarily to see if that has helped out.

This page can help provide info on that process, if needed: Block connections to your Mac with a firewall - Apple Support

1. On your Mac, choose Apple menu  > System Settings, click Network  in the sidebar, then click Firewall. (You may need to scroll down.)

2. Turn off Firewall.

Cheers.

Thanks for replying, DazzAU, and that additional info, it really helps! If you are still having this issue, please contact Apple directly for further investigation:

Have a great day and thanks for using the Apple Support Communities!

I just ran in to the same problem. I connect to a shared folder on my Mac Mini M1 from my Macbook Pro M1 and after upgrading to Ventura, My Mac Mini will show up in the network but I can't connect to it.

I was able to get it working again (for now) by turning off file sharing in settings. I also had the issue that the slider didn't move to show it had been turned off, but I could see the icon for the MAc Mini disappear on the Macbook pro so I knew it was turned off. I turned it back on and all is working again for now. Appears to be a glitch from the upgrade, but who knows.

I think I isolated my problem. After upgrading, every time I used Adobe Lightroom Classic my file sharing would quit. I keep my photos on an external drive on my Mac Mini M1 so this is an issue when I am using my M1 Macbook Pro. I stopped using Lightroom and my file sharing is working properly with no issues. Might be an issue where Lightroom needs to be upgraded by Adobe.

This is a problem with Ventura, after installing the Share folder continually stops working. Having to restart every few hours.

UPDATE: Right after I posted this, sharing failed again. So, maybe Lightroom wasn't the problem. Apparently, I just got lucky for a few days
