git-annex/doc/bugs/smudge_errors_on_os-x.mdwn

### Please describe the problem.

When following the instructions in [[tips/unlocked files]] on Mac, I am seeing an error message when smudge is run.

This causes the file to end up in git's object database (`.git/objects`) instead of git annex's (`.git/annex/objects`).

I tried the same steps on linux with the autobuilder version (7.20190508) and got no error and the data ended up in git annex correctly.

### What steps will reproduce the problem?

### Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)

YES! Git annex is an amazing tool and it's the backbone of my long term archiving workflow. I also use it for archive management at work and it's proven to be incredibly useful. Thank you for continuing to maintain and innovate with git annex!
