Unable to copy files to Umbrel share

#1, there should be a Beta section in this community now that we’re able to beta test.

#2, I’m running 1.4 beta 1. I’ve shared the Umbrel and mounted the share in MacOS. I was able to copy one folder of files (about 4GB) to the share. It copied, but I received an error at the end. Ever since then, I’m unable to successfully copy any files to the share. I receive the error “The operation can’t be completed because an unexpected error occurred (error code 100093)” in MacOS. The file appears, but has a 0 bytes size.

I tried copying a file using Terminal in MacOS with the following command (example):

cp /Users/username/path/file.txt /Volumes/Umbrel/Downloads/path

and get the error:

cp: /Users/username/path/file.txt: could not copy extended attributes to /Volumes/Umbrel/Downloads/path/file.txt: Attribute not found

I can copy files from the share to my Mac with no issues. And of course I can copy files to the Umbrel through the web browser using the Files app and Upload function in it.

Everything is connected over Ethernet. I have restarted the Umbrel, my Mac, and the network router and switch. I have also turned off the share and then shared it again. MacOS in on the latest version 15.3.

EDIT: Update… transferring large files through the Files app in the web browser fails. I’m testing using Umbrel as my Plex server. When I copy new large media files (i.e. a 16GB MKV file), the transfer doesn’t complete. I was able to copy a couple smaller ones (6GB and 8GB), but it stalled at the end of the second and failed on the third. Then I tried copying the third by itself and it wouldn’t compelte. I appeared to be copying (albeit rather slow), but when I checked on it later all progress info was gone and it wasn’t doing anything.
