Hello there,
I am wanting to create a custom FSKit extension, and am trying to get the sample passthrough project running:
https://developer.apple.com/documentation/fskit/building-a-passthrough-file-system
I have just followed the basic instructions from the tutorial above, so have:
- Selected my team for the signing certificate (required for FSKit module).
- Built and run.
- Enabled "Passthrough file system" under "File System Extensions".
- Made a test directory to mount to:
mkdir ~/test
But when I run the mount command, I get the following error:
mount -t passthrough ~/Documents ~/test
mount: Loading resource: The operation couldn’t be completed. (com.apple.extensionKit.errorDomain error 2.)
mount: exec /Library/Filesystems/passthrough.fs/Contents/Resources/mount_passthrough for /Users/xxxxxxxx/test: No such file or directory
mount: /Users/xxxxxxxx/test failed with 72
The contents of /Library/Filesystems/ is empty, so I don't know if allowing the extension is meant to add something to this directory or not.
Any help would be much appreciated!
Hi there,
Many thanks for the response. I ended up finding the solution:
It works if I set the mount target to be any folder in the Home directory, so long as the folder is not inside one of the default folders (Eg. Documents, Desktop, Downloads, etc.)
So these work:
- mount -t passthrough ~/Documents ~/test
- mount -t passthrough ~/Downloads ~/test/best
But these will not work:
- mount -t passthrough ~/Documents ~/Desktop/test
- mount -t passthrough ~/Documents ~/Downloads/test
I tried these after restarting my computer too, so I don't know whether restarting had an effect or not.
In the sample project guide, each time the mount target is mentioned it is prefixed with "For example...", so I assumed I could use a target located elsewhere like in ~/Desktop
Regards,
