Hi Tomasz,

Thanks for reporting the bug!

That's the actual problem. This is a USB drive where you've copied the
/Application folder under OS X, right? Which OS X version have you been
using?

I believe this bug was fixed in 1.1. Unfortunately, FreeBSD port is
outdated. I've tried to contact the maintainer about a month ago without
success.

Yes, the drive is USB/Thunderbolt Lacie Rugged 2TB (using USB
connection), MacOSX Yosemite 10.10.* (hard to tell exactly as several
computers use it).

Yes, I have also noticed that and reported to FreeBSD FS/BUGS mailing
list and the maintainer. If there is no response I will try to verify
and prepare an updated version :-)

Thank you! :-)

I see. I relaxed this check in 1.1, so you just need to upgrade to the
latest version of fuse-exfat and exfat-utils. Let me know whether they
work for you.

This would be great! Please keep me informed.
