NAS Access in Catalina issues

@Mike_App

I actually did not use the Go > Connect to server method of accessing the drives/shares, as that approach caused major issues for me previously. Instead I rebooted my computer, then went into Finder > Preferences > General > Show these items on the desktop, and checked Connected Servers (see screenshot.) Then I went into the sidebar in Finder, and under Locations, connected to my NAS. Once connected, the icons appeared automatically on my desktop, and I dragged them to the Favorites section of the Finder sidebar.

If you are seeing question marks, try rebooting your computer, and then follow the steps above. In my experience (and in the experience of several others in this thread), using the Go > Connect to server method eventually caused serious issues, especially after the computer and NAS were restarted.

PS. I have used this approach on two Macs on my network, and it is currently working.

Hi bsanders44,

Happy at least it's mitigating the pain.

But it's really sad that mother Apple is not willing to fix what clearly appears to be a trivial issue in Finder share management. There's must be a difference in what happens over the hood pushing on the network tab differently from pushing on the favorites one. Something that a SW engineer would fix in day. If only Apple would ask him to do. Really sad story from quality wise point of view.

Regarding the workaround: I can confirm that I'm using this workaround from months and a part from some question marks time-to-time I've never experienced Finder crash. Also TimeMachine is working fine.

I think the disconnect popup/dialog can appear legitimately if the device's network connection is lost. It's only on Catalina, so far, that I've seen it happen due to the underlying connection issue.

I suggest that everyone who is having success with Cemento's workaround go and mark his response as helpful, so it shows up first for users coming into this thread: https://discussions.apple.com/thread/250794335?answerId=252112800022#252112800022

Unfortunately, the IP address approach has also been marked as helpful, but doesn't work longterm for many people. Anyone who's marked that as helpful, but has had the issue recur, should go back and unmark it to avoid confusion.

@Martin Deisting,

The Synology NAS is connected by its IP-adress in Finder (GO - Connect to server).

The Time Machine share was dragged to the Finder left column.

I also implemented a Automount app (ConnectMeNow, it is in Dutch), but that does not seem to help very much. If Time Machine is launched, it opens the share directly.

After applying this, I have not had the horrible message above that the TM bundle is corrupted, for more than 1 week now. (always nice to see this in French also...., misere international, non?)

For the sake of reliability, TM is also making a backup on a local USB-drive.

Bad news, unfortunately, the problem re-appeared for me :-(((

Just to be sure that I did everything correctly:

• typing "sudo nvram {...}" in Terminal as you explained
• reboot
• CTRL+K to connect to smb://192.168.1.75 in my case
• Then double click on the folder of my Time Machine (TM in my case)
• I did not drag & drop the share in the left column of the finder, I will do so to see if it changes something
• Launch again Time Machine (from scratch on my side)

--> it did not solve my case neither for accessing NAS nor to be able to perform the Time Machine backup.

Nothing else ?

Of course, I do backup on a separate USB Disk of course, but unless I am mistaken, I can't backup this Time Machine backup on an alternative disk to keep it safe, reason why I also do a Time Machine on my NAS (to allow another alternative in case the USB Hard Disk break - and usually, USB Hard Disk is with MAC, and therefore if MAC is stolen, Hard Disk as well...)

Do you think that the TM "horrible misère internationale" as you said is linked to this Finder connection ???

Any other idea ?

@Fly_PetitPrice you tried the most complicated workarounds before trying the simplest thing that many people said worked for them? Let us know how accessing your shares from “Favorites” works if you try. It did for me, but I never had a TM issue, only share access.

Well, at least for me, it does not work, TM is still sending error when completing the check (1st TM is ok, but not the check...).

As per the node, it looks like so far I can access them, but usually the problem occurs after several days, and if TM is not solved, I am afraid that it will be the same with access to folders.

Let's cross finger and let's see...

@Remulus, @Fly_PetitPrince

OSX release 10.15.6 fixed the problems with connecting NAS-shares.

However the problems with TimeMachine remained: after an initial TM backup, the following incremental backup failed, with the famous message. This appeared to be a problem with Norton 360. It was necessary to complete uninstall Norton, to get TM working again. Norton is completely silent about this and no hint on a solution. Very disappointing for a lifetime Norton customer, like me.

And we also, explicitly or implicitly accused Apple for the TM problem, which now appeared to be false.

Anyway, end good, all good.

Cheers, Martin

So we h

Some positive feedback because for me the problem is fixed. Previously nothing worked and the NAS was basically not usable and Finder crashed every time I tried a connection. Also tried various workarounds from this forum but nothing was even close to stable.

Now with the latest upgrade from Catalina to version 10.15.6 and a QNAP TS-473 with firmware version QTS 4.4.3 onwards everything works like a charm. Like it did previously in Mojave.

I'm sad to hear others are still struggling.

For me it is working fine too.

The only problem I have is with Pages and Numbers. I can create a new document and save it to the network share. However, when I update the document I can't save it anymore (error "File can not be saved" or something). I used to have this problem last year, but it was solved to save as a single file. Alas this isn't working anymore. It make it impossible to work on a network share from Pages or Numbers.

All other programs I have (Word, Excel, Lightroom, PDF Expert, etc..) are working fine. So I assume it is a problem with Pages and Numbers itself.

Thanks, did all that already, but to no avail. It appears to really be a macOS catalina problem.

yeah, sorry, it is essentially an IT problem. And because I know that, I tried to explain the steps as easy as possible.

Also confirming that accessing my synology NAS with finder works now all the time.
