Transferring large files through your local network could cost a lot of time, this is the main reason why we need to mount the micro SD card on a Mac (read-only).
With Raspbian image, two partitions are created on your SD card. The first one is FAT16 which is the boot partition and the second (ext4) the Raspbian OS.
Reading a Linux partition on Mac OS not possible by default. In order to read this particular filesystem, FUSE for Mac OS need to be installed.
If you don't have Homebrew you need to install it.
brew cask install osxfuse brew install ext4fuse
2. Plug your SD Card into your Mac
3. Get the partition identifier
Open your terminal.
diskutil list diskutil list
In my case : disk2s2
4. Create a mount point
sudo mkdir /Volumes/raspberry
5. Mount the SD Card
sudo ext4fuse /dev/disk2s2 /Volumes/raspberry -o allow_other
allow_other : readable by everyone
To unmount the disk :
sudo umount /Volumes/raspberry
