Aliases on shell

Since .bashrc is not working, i managed to do some tricks

Edit /etc/profile and add the following lines.......

 

Dealing with ISO Files with hdiutil

Creating an iso file from a directory

hdiutil makehybrid -iso -joliet -o output_image.iso input_directory/

Mounting an iso file into /Volumes/

hdiutil mount source_image.iso

 

Writing image to SD card

These are the steps to write an raspberry pi OS image to an SD card on MacOS

1. Insert card on reader

Identify the disk number

diskutil list

2. Unmount the disk

unmountDisk /dev/disk2

3. Write the image

sudo dd bs=1m if=hassos_rpi3-2.12.img of=/dev/rdisk2 conv=sync

4. Eject card

sudo diskutil eject /dev/rdisk2

Done!
