I can no longer save changes to files on network folders after updating MacVim to Custom Version 8.1.950 (155). I am on Mac OS X 10.13.6. I have several network shares mounted as smbfs.
After trying to save a file, the changes are not saved, the buffer shows as still modified, and I get an error: E667: Fsync failed
I tried restarting MacVim after removing .vimrc, as well as doing defaults delete org.vim.MacVim, but nothing helps.
MacVim can save changes to files on my local disk with no problems. Also, the system vim (/usr/bin/vim) can save files to local or network files with no problems.
Nothing has changed on my machine, other than updating MacVim.
