Catalina SMB problem

Apple is not here to read your thinly disguised epithets. Please address them via https://www.apple.com/feedback/ though it would be more productive if you defined the problem for them there rather than using your post as a rant

A quasi-technical answer to removing support for old protocols is that security holes may be insoluble in old versions, so the industry moves on. Upgrade your NAS firmware if you have not done so already, and work from there

I faced same issue with Samba shares today. After migrating my old profile from High Sierra to Catalina, noticed that all my Samba shares stopped working, with the exception of one that was mapped through a static IP address. Rest of shares that required DNS resolution didn't. So I tried everything mentioned in this thread nothing worked.

I then deleted one of the saved shares and created a new one, filling the same network information as before, and noticed the new saved shares had a different icon as before (see pic). The protocol was also determined automatically as I was typing "smb" in the input field.

In a nutshell, the Samba shares need to be recreated, after deleting the old ones. If they show the old way, which is a small blue-ish icon, they won't work (it seems the OS don't even use Samba to attempt to connect to the remote share).

They need to show as gray squared storage icon. See pic below (the first 2 work, the 3rd won't):

Hope this helps someone.

I have a similar question posted in the Desktop area. My iMac keeps asking "You are attempting to connect to server xyz" with option to Cancel/Connect, but then fails to connect. I presume it is the same issue. It does not stop presenting this message which is very annoying. Do you have the same prompt? Have you been able to find a solution already? My server (Netgear Stora) does seem to connect through finder using the AFP:// connection, but this does not prevent the message from showing up. Regards, Henk

Check you NAS is broadcasting the correct Bonjour credentials.

You may need to reboot NAS, Router and Mac at some point in this battle (that started with Catalina for many of us). Choose a logical order if so. I'd want the router back first the NAS second and the Mac third

You might also want to add your NAS to your login items in system preferences

I was not able to connect my year 2011 iMac to my year 2019 iMac that was running Catalina. Prior to the upgrade to Catalina, I had no issues in this regard. I set both iMacs to use SMB rather than AFP. This in itself did not solve the issue. I then powered down both computers and my router. I then powered up my router, then I powered up the year 2011 iMac, and then finally I powered up my year 2019 iMac. I was then able to connect via Finder on my year 2019 iMac by clicking on Network in the sidebar of Finder and then I selected the year 2011 iMac. I then entered my computer password in the pop-up window.

jessika67 - actually its the first problem I've ever had with that OS since I start using it 5yrs ago and compared to Win* its light years ahead (and I was using the Win for about 15yrs.). So if you are not gonna give any practical solution, please dont waste your time and just go and make your hubby a sandwich.

I have tried all sorts of stuff to get this to remain connected and I have yet to find something that works. I get error's that it cannot connect. Now this is not perfect, but it works. Once it respawn's everything works as it should. The problem with is I only get 24-ish hours before it craps out. What we need is a real fix for this. Whether it's SMB or AFP neither holds a connection to the NAS. Now in my instance I'm using a 2017 Netgear ReadyNAS 424. Bottom line, it works.

Since macOS was updated to 10.15.2 I have the same problem with SMB shares, every ~24 hours I can't reconnect the SMB shares from a Qnap, the only fix I found is to reboot my mac (that's very annoying!) Restarting SMB service on the NAS or rebooting it didn't help and, as I said, the problem began after macOS was updated from 10.15.1 to 10.15.2, I never experienced such a problem before.

Same here. I can connect randomly, but sometimes it's so slow that the entire system collapses and I have to reboot. Not even a shut-down, start works, as it keeps the slow transactions I'd already started, on process.

I have been struggling connecting to my QNAP NAS via SMB for a while now too (Catalina 10.15). First I switched to afp protocol which seemed to work better, but I hate workarounds instead of solutions. In the end, this seems to have fixed the problem for me: delete the Finder preferences.

Use the Finder menu to go to a folder (Shift Cmd G) and copy this path in: ~/Library/Preferences/

Then locate the file: com.apple.finder.plist and Delete it (move to trashcan).

I always empty my trash too, not sure if that's important here.

SMB is lightning fast now, faster than it's ever been.

Hope this helps!

Deleting the finder preferences didn't fix the problem for me. After a while the mappings have disconnected and I can't reconnect them. I also tried to force a restart of the finder, but that didn't work either. The only known workaround in my case is a complete reboot of the computer which isn't convenient.

Just happened again, tried to relaunch the finder, but it didn't fix. When I try to connect to the SMB I get the small "connecting" window, but it never connects. Thanks for sharing, but rebooting seems to be the only working fix in my case.

Not a fix, but at least better than rebooting: Go to System Preferences, Sharing. Untick "File Sharing" and then tick it again. This will restart some services. It fixes the issue for me temporarily without rebooting.

Fritz!OS as of yet supports only SMB version 1 which is deprecated and no longer supported on Mac OS Catalina. This applies to the current stable branch of Fritz!OS.

The "Labor"-branch (not yet labelled as stable, but usually quite mature) of Fritz!OS supports SMBv3. So you ought to download the most current "Labor-Version" applicable to your router.

It seems to be the same basic problem with the other posts here: NAS-OSes or 10 year old MacOSes that still offer only SMBv1 and a modern client that out of security concerns refuses to talk this outdated protocol. NAS-vendors will probably roll out updates, too.

BTW, de novo installations of Win10 (not updated ones) also do not support SMBv1 out of the box without tinkering…

I have the same issue, my Huawei must be using SMB 1 or 2, but it doesn't have support for SMB3. It seems like Apple has removed support for SMB 1 and 2, I am sick of Apple doing this ****. Do they have any respect for their users, we all can't upgrade just because Apple wants us to. Why would you remove support for old protocols????? I had no issue with connecting until I downgraded to Catalina. F^$K Apple, I'm going back to windows on my next computer.
