Important information for Mac
Users:
*Note that UltraProjector, Inc. does not support
Mac computers and will not be liable for any
damages resulting from use of the information
below. This information was provided by
one of our customers and is included here for
reference only. Proceed at your own risk.
A
common problem that occurs when using a Mac is that
hidden files
are deposited into the UltraProjector's flash
memory that will cause it to hang. When you
connect to a Mac, Spotlight takes over and
creates a few hidden “dot” files on the USB file
system.
Here’s a command you can use to remove those
files. First, open up Terminal and then change
directories over to the USB UltraProjector
device:
youruser@localhost:~$ cd /Volumes/NO\ NAME/
If
you list the directory, using the “-a”
option, it will show “all” files, including
invisible files (files that start with a dot as
their first character):
youruser@localhost:NO NAME$ ls -a
..TrashesStorybook and Audio.avi
..._.Trashes
.Spotlight-V100.fseventsd
There you can see the problem files -- .Trashes,
.Spotlight-V100, etc. Use the “rm” command with
a few options to get rid of them. -R for
recursive (so it goes in to each directory), -d to tell it to remove
directories, and -f to force the removal without
prompting you each entry for verification:
youruser@localhost:NO NAME$ rm -R -d -f .*
rm: "." and ".." may not be removed
It’s okay that it cannot remove “.” and “..” --
those are not real files, but references. “.” is
the current directory (so an “ls .” shows where
you are) and “..” is one directory up (“ls ..”
would be “/Volumes”, in this example):
youruser@localhost:NO NAME$ ls -a
...Storybook and Audio.avi
You can see the dot files have been removed.
