WebDAV on macOS Big Sur 11.2 on M1 didn't work

I opened a ticket about this issue weeks ago. I also had phone contact with an Apple second or third level support. He told me that the engineers are able to reproduce this. Still we see no fix...a shame! I'm getting impatient...

Pretty much. My official recommendation would be to use some 3rd party software for WebDAV. Transmit (https://panic.com/transmit/) is probably the most popular such tool. I don't actually use it myself, so I can't comment on how well it works.

I would not recommend using Apple's WebDAV. Years ago I wrote an app that I hoped would eventually be a good competitor to Transmit. In my naïve confidence of all things Apple, and my love of XML, I used WebDAV as a local translation layer. That was a bad idea. I discovered that there were serious bugs in Apple's WebDAV implementation and that Apple had no plans to fix them (that's what they told me). Apple suggested I use SMB instead, but that is significantly more complicated to implement, so I dropped the idea. This was 8 years ago. I don't see how WebDAV has gotten any more popular since then.

A few years after that, I even had an opportunity to use a super-fast, well-supported enterprise SMB network. Again, I was disappointed in the Mac's networking support, this time with SMB.

My official recommendation is to never use network connections as network drives. By this I mean never attempt to directly open a file on a network volume. Instead, drag the file to your local machine and work on a copy of the file. When you are happy with your changes, drag the file back to the network volume and overwrite the old version. Hopefully no one else has made any changes to the file since you made your copy. This is the same workflow you would get for any 3rd party tool anyway. Transmit might allow you to mount remote connections as Finder volumes, but I don't know how well that will work.

If you have any option for a web-based database, or well-supported file sync system like iCloud or One Drive, use those instead.

I realize people probably don't want to hear this. I know I don't like saying it. But at a certain point, you just get tired of network lockups and corrupt files and you just want to get your work done and go home. Follow the instructions above to do that.

Same problem here again and again with a Synology NAS via WebDAV in a pandemic setting! I can't believe that I have to start my old 2011 MacBook to execute a very simple operation, that I can't do with my brand new and quite expensive M1 machine. I've never seen that pink flashing panic mode screen before, and then so many times straight away, because I've just been used to opening and editing files for more than a decade. Praising Apple for stable running machines came to an end!! Is this their strategy to promote iCloud? Time to say good-bye?

Same issue here, I use webdav everyday for working, it would be great to have a fix on this issue

Just have a same problem. Mac Mini M1 restart after rename one of the folder in Webdav. Any update on the issue?

Apple please consider this issue, it is supposed to be a native function on MacOS.

Are we the only 3 peoples in the world using WebDAV with Mac M1?

But it works on intel mac with the same OS.

Then use an intel Mac instead. I can't give you anything other than alternatives. I can't force Apple to fix its code.

Same problem here! Webdav crashes when I try to write a file on my Synology NAS via WebDAV or when I try to rename a folder

Same problem here. Annoying...
