Mac OS X Catalina File Sharing Issue

I had this problem since upgrading to Catalina... I finally figured it out. Simply uncheck "Share files and Folders using AFP" but leave the "Share files and folders using SMB" checked in the options under file sharing. Everything works now!

Did you try this? I did this on 2 Macs and it worked....

With Catalina, they made some security changes... I had this problem since upgrading to Catalina... This is what worked... Simply uncheck "Share files and Folders using AFP" but leave the "Share files and folders using SMB" checked in the options under file sharing. Everything works now!

I had quite the same issue when upgrading my iMac Pro to Catalina. My shared render folder was not accessible any more to my other Render Macs. But the solution was quite easy: switched off File Sharing > Restart > then switched it back on and Voilà! Sharing worked again like before.

I had a similar problem. MacBook Pro with Catalina and iMac with Mojave on the same network. Both machines could see the other. MBP could access all folders on iMac but iMac could only access some folders and not for example Documents on MBP. Spent ages on the phone to two very helpful Apple support people. Eventual solution was to turn off file sharing on both machines. Restart both. Turn file sharing back on on both. Relaunch Finder on both. This may be overkill but it worked for me. We shouldn't have to waste time on problems like this though. Software testing before release should find them.

I followed himerus solution and it worked, in my case I was trying to access a USB drive plugged to another Mac on my network. I was able to access everything except that particular USB drive.

On the computer with the USB drive plugged I disabled and re enabled file sharing. Then on this other computer I relaunched Finder (option click on Finder)

Seems a third reboot was in order. Also the drive does not appear under locations the way it used to. You now have to select Network in a Finder window, then navigate to the drive on the network.

I was able to replicated this issue, and solve it with the following steps:

Computer 1 (file sharer): Disable and re-enable File Sharing under Settings > Sharing. No reboot is required

Computer 2 (file consumer): Either reboot, or force quit/relaunch Finder, then browse to your normally shared directories.

Running Catalina 10.15.2 and my iMac cannot see my laptop on the same network. Tried unchecking and checking FileSharing, relaunching Finder, rebooting, etc.

The issues persist. My laptop cannot see the iMac and vice versa. Any other steps to try?

I'm still unable to connect to the laptop sitting on my desk. I have even created a new account, just to try and get to it. Every attempt just causes the dialog window to shake. Have tried the user ID on the MacBookPro, the Apple ID... have restarted, force quit the finder on both. Still unable to see the other drive.

Why is this all of a sudden so difficult?

Such a simple fix. i have looked all over Google for a week and couldn't get Desktop, Documents, or Downloads directories to show any files through either afp or smb. All other directories and ftp worked Ok. Thanks for this.

That was helpful for me and I marked it as such. Thank you. Slight caveat to my setup is that a reboot was required to get this to work correctly. Perhaps that could have been resolved with a Finder relaunch; I rebooted, though.

What you have attached is your Macs TCP/IP settings.

If you look there you can see that you are using DHCP to get an IP address from your wifi router.

What you need to then do is log into your router and set the DHCP reservation for your devices to make sure that they use the same IPs every time they log in.

Here is the basic instruction of how to do this.

1. Head to your router's configuration tool by typing in your router's IP address in your browser's navigation bar. Usually this is something like 192.168.0.1. You can check it by running ipconfig in a Command Prompt, or heading to System Preferences > Network on a Mac.
2. Find the DHCP reservation setting. This could also be called "DHCP Static Lease" or something similar. On my router, it was under the "Gateway" category.
3. Head to the computer for which you want to reserve an IP address and find its MAC address. Once again, you can find this by typing ipconfig into a Windows Command Prompt, or by going to System Preferences > Network on a Mac, clicking on your Wi-Fi card or Ethernet port, hitting Advanced, and going to the Ethernet tab. Your MAC address will be in the form 00:00:00:00:00:00. Note that a Wi-Fi card and Ethernet port will have two different MAC addresses, and you can't assign them both to the same IP, so pick the one you use primarily.
4. Type that computer's MAC address into the first entry in the DHCP Reservation setting. Then, type in the IP address that you want to reserve for that machine. Hit Apply, or whatever button is available to you.
5. Repeat with any other computers that you want to reserve

Once reserved go to this page in your Plex settings and reserve those IPs

Save and Reboot the server and Mac and you should be good to go.

Give that a try

2020/4/25 Apple still have this bug not fixed. It‘s bothering me every day.

I tried it today, but it will take some time to see the results.
