This error, or more precisely
NTFS-3G NTFS-3G could not mount /dev/disk# at /Volumes/XXXXXXXX because the following problem occurred: Did not receive a signal within 15.000000 seconds. Exiting... [Close]
started to appear when I installed MacFuse and NTFS-3G on a new MacBookPro 2014 running Mavericks.
It is pretty harmful, since the NTFS volume would mount as well… but annoying.
Since I understand quite few people are experiencing this on the Net and I want to remember the solution I adopted, I have decided to report here the fix I’ve found.
