NAS Access in Catalina issues

I don't think it is router issue. Because I rebooted my router pervious but the issue still here.

I also have a MacBook Air which is the old system. I think it is 10.14.

The MacBook Air does not have any issue like this.

> that the issue could be due to Catalina dropping support for previous SMB protocols.

I tried a while back to enable only SMB1, or SMB2, or SMB3 on the NAS, but this did not help. Also, the issue goes away (for a little while only -sad!) after a fresh reboot, so it cannot be related to dropping a protocol, otherwise the issue would be present always.

UPDATE:

Fresh Reboot in Mac.

Reboot of Router.

Disalowed SMB1 on Synology.

Connected to NAS-Share with smb://<user>@<nasname>.local , selected 19 Files ( PDF, 1 JPEG ) on share. Dragged them down to local folder ... super.quick

switched on NAS to subfolder and back, selected same Files to pull down on local Folder ... FINDER HANGS.

So the guys need to FIX the networks and probably FINDER Behavior as well => "Finder doesn not react"

I go down to the cellar and reactivate my 16bit Computer now.

I am so much with you.

And to me it appears so much inacceptable ... i somewhere her did write the same, saying: my 4k Bugs MacBook Pro is Slower than my Old of 2006 running El Capitan.

Furtermore it not anymore a concept: MacBOOKs NEED Storage ... and this is a NAS.

As ths Issue is with many NAS, it is the same behaviour as if Bentley does not care if Tires and Wheels not anymore fit on their cars .. user Issue: You do not need to drive, you can sit inside and have it warm. More dependent is, we sell you a music stream running on your bentley audio installation

==> WRONG Attempt.

Should we create e.g. a Facebook side and Post that stuff and invite as many poeple around the world we know?

Often when I force quit, Finder will not completely quit, and/or won't restart properly. I wind up with no icons on my desktop, and Finder generally non-functional. I have to do a complete reboot to get everything working again.

exact and so this is not an option and also not a workaround.

As said, my Mac FIND the NAS but they lose performance with preview. Disabling the preview option makes it faster.

But still, something as per each access of NAS stored files makes it slower and slower

==> Preview is buggy ( QuickLookGui or so process hangs )

==> Network layer on Catalina is buggy

DEAR APPLE GUYS, I LEARNED, YOU CHECK THE BLOGS.

SO PLEASE BE SO KIND TO PICK THIS UP ... THIS IS A SYSTEMIC ISSUE.

PLS CHECK BLOG other than this AND YOU FIND EVIDENCE.

It is really an apple issue. I have installed windows 10 on my macbook using bootcamp and have no issues at all using my NAS on windows 10, but it’s unworkable in MacOS Catalina.

I wish Apple would recognize this issue and resolve it.

It seems the problem has gotten worse with 10.15.2. It used to be I had show-stopper issues on my MacBook Pro but no real problems on my iMac Pro. After updating, nothing got better for my MBP, but I can no longer trust that my NAS connections will remain stable enough for my video editing software (Davinci Resolve) on my iMac Pro. It's TERRIBLE.

I was already more than halfway inclined to get a Threadripper system instead of a 2019 Mac Pro for 2020, but gosh, if something as as simple as a NAS no longer works with the OSX ecosystem, there's absolutely no reason to remain on Macs of any kind.

Alas, I've tried flushing my DNS cache but the issue returns. I'm glad you were able to at least get your backups to complete, but the issue comes back for me after 2-3 hours from rebooting.

Perhaps the clever moderator who is deleting many of the posts here can do something productive and try to get an ETA on a fix from Apple? This is a MAJOR bug in Catalina that is rendering Macs unusable on networks with a NAS, and we need more information, not censoring and less information.

I have been having problems with my NAS (QNAP TS-231P) on my MacBook Pro (mid 2014) running Catalina 10.15.2. Clicking on my NAS on the sidebar or via Network gets me a "Connection Failed" and a "Connect As ..." button that does nothing. Connecting via AFP and the NAS network address works temporarily, but the problem keeps coming up. Before 10.15.2, my NAS got along with my Mac just fine. Basically, the same story repeated many times in this thread.

I can log in to my NAS management software on the MacBook via the web interface. All of its software is up to date.

I also run Windows 10 (on an older Mac Mini) and it gets along with the NAS just fine, no changes. So, Apple, I think this one is on you. Please fix soon. This problem is very annoying.

Thanks.

On of the commentors said that they are running the 10.15.3 preview and it seems fixed in that.

this is my main machine, and I can't take the risk, but have others tried that ? Does the preview for .3 really fix the issue ?

If some of you who have the flexibility to try it and report, would be great!

> I'm downloading 10.15.3 beta2 now. Will report later.

Nope, unfortunately. Seemed better for a while, switching user, connecting disconnecting, standby resume, but when turning Wi-Fi off and then back on, the sempiternal "cannot find directory" dialog came back again.

But... there seems to be some progress: I now always see the NAS in the side bar and, when I click on it, the NAS directories. I'm also now always connected to the NAS. And when I press disconnect (yes, that button now works again!), the Finder reconnects automatically.

So, not quite there yet, but some good steps in the right direction. Keep up the good work Apple!

Having the same issues for some time...

I can connect via Finder -> Go -> Connect to Server ... but it doesn't stay connected. Clicking on Connect as... doesn't work like others have mentioned. Restarting the iMac used to fix this issue but that isn't working anymore though I haven't made any changes. Force-quit of Finder also used to work before but that has stopped working as well. So none of the workarounds are really work arounds. Flushing the DNS cache also has no effect.

Somehow TimeMachine continues to be able to back up to the NAS shared folder for me which seems interesting. Keeping my fingers crossed because I don't know when that will stop as well (like the previous workarounds for Finder that stopped working). Really waiting for Apple to fix this.

Hello,

+1 to this issue. I manage a small design team with a Promise Pegasus RAID drive attached to a Mac Mini on our network.

Since upgrading to Catalina, the ability to connect to the Mac Mini via Finder 'Connect As…' results in a Failed message.

We can still connect via Connect to Server (Apple + K) but given how often we need to save or open things on the shared drive, it's very frustrating.

This issue has been getting steadily worse for me. Now my NAS no longer shows up automatically in Finder, even though Bonjour is on. Instead I have to use the Go >> Connect to Server route, and manually connect. The connection is even less stable now, to the point where my TimeMachine backup hangs and never completes. Restarting the computer and even the NAS is no longer clearing the issue. Clearing the DNS cache doesn't help, nor does any other "workaround". My computer is completely unstable on any network with a NAS, and I have to restart constantly as apps that seemingly have no relationship to the NAS hang and cannot be restarted.

This is a SHOWSTOPPER issue, as it not only undermines the stability of OSX, but it jeopardizes user data. There are only so many times that a connection can be improperly broken while running a TimeMachine backup or accessing/updating a remote Photos library before the target data becomes corrupt.

FIX THIS APPLE!
