Luckily you can disable some of the extra hidden files that Mac OSX adds by running a few commands to disable

search indexing and create zero byte placeholders. Follow the steps below to maximize the amount of space available

on OSX:

Prevent & Remove Mac OSX Hidden Files

First find the volume name for your board. With the board plugged in run this command in a terminal to list all the

volumes:

ls -l /Volumes

Look for a volume with a name like CIRCUITPY (the default for CircuitPython). The full path to the volume is

the /Volumes/CIRCUITPY path.

Now follow the steps from this question (https://adafru.it/u1c) to run these terminal commands that stop hidden files

from being created on the board:

mdutil -i off /Volumes/CIRCUITPY

cd /Volumes/CIRCUITPY

rm -rf .{,_.}{fseventsd,Spotlight-V*,Trashes}

mkdir .fseventsd

touch .fseventsd/no_log .metadata_never_index .Trashes

cd -

Replace /Volumes/CIRCUITPY in the commands above with the full path to your board's volume if it's different. At this

point all the hidden files should be cleared from the board and some hidden files will be prevented from being created.

However there are still some cases where hidden files will be created by Mac OSX. In particular if you copy a file that

was downloaded from the internet it will have special metadata that Mac OSX stores as a hidden file. Luckily you can

run a copy command from the terminal to copy files without this hidden metadata file. See the steps below.

Copy Files on Mac OSX Without Creating Hidden Files

Once you've disabled and removed hidden files with the above commands on Mac OSX you need to be careful to

copy files to the board with a special command that prevents future hidden files from being created. Unfortunately

you cannot use drag and drop copy in Finder because it will still create these hidden extended attribute files in some

cases (for files downloaded from the internet, like Adafruit's modules).

To copy a file or folder use the -X option for the cp command in a terminal. For example to copy a foo.mpy file to the

board use a command like:
