Raspberry Pi Imager is the recommended option for most users to write images to SD cards.
Determine SD device
- Insert the SD card in the slot or connect the SD card reader with the SD card inside.
Command Line
Download Noobs Os
diskutil list
Example (the SD card is /dev/disk2 - your disk and partition list may vary):
Graphical / Disk Utility
- From the Apple menu, choose 'System Report', then click on 'More info..'.
- Click on 'USB' (or 'Card Reader' if you are using a built-in SD card reader), then search for your SD card in the upper right section of the window. Click on it, then search for the BSD name in the lower right section.It is in the form
diskN
(for example,disk4
).Record this name. - using Disk Utility, unmount the partition.Do not eject it.
Copy the image
Command Line
Note: The use of the dd
tool can overwrite any partition of your machine.If you specify the wrong device in the instructions, you could overwrite your primary Mac OS partition!
The disk must be unmounted before copying the image
Copy the image
Replace
N
with the number that you noted before. Note therdisk
('raw disk')instead ofdisk
, this speeds up the copying.This can take more than 15 minutes, depending on the image file size.Check the progress by pressing Ctrl+T.
If the command reports
dd: /dev/rdiskN: Resource busy
, you need to unmount the volume firstsudo diskutil unmountDisk /dev/diskN
.If the command reports
dd: bs: illegal numeric value
, change the block sizebs=1m
tobs=1M
.If the command reports
dd: /dev/rdiskN: Operation not permitted
, go toSystem Preferences
->Security & Privacy
->Privacy
->Files and Folders
->Give Removable Volumes access to Terminal
.If the command reports
dd: /dev/rdiskN: Permission denied
, the partition table of the SD card is being protected against being overwritten by Mac OS. Erase the SD card's partition table using this command:That command will also set the permissions on the device to allow writing.Now issue the
dd
command again.
Eject
After the dd
command finishes, eject the card:

This course introduces you to the low level internals of the iOS and OS X kernels from the perspective of a security researcher interested in vulnerability analysis, kernel rootkit/malware analysis/detection or kernel exploit development.While this course is concentrating on MacOS High Sierra on the x64 cpu architecture the latest security enhancements of iOS 9/10 will also be discussed. The course material was updated to the latest security features of MacOS High Sierra and iOS 11. Apple incorporated lots of changes into iOS MacOS High Sierra and iOS 11. Therefore there are many changes to the material from previous course.

BIO
Stefan Esser is best known in the security community as the PHP security guy. Since he became a PHP core developer in 2002 he devoted a lot of time to PHP and PHP application vulnerability research. However in his early days he released lots of advisories about vulnerabilities in software like CVS, Samba, OpenBSD or Internet Explorer. In 2003 he was the first to boot Linux directly from the hard disk of an unmodified XBOX through a buffer overflow in the XBOX font loader. In 2004 he founded the Hardened-PHP Project to develop a more secure version of PHP, known as Hardened-PHP, which evolved into the Suhosin PHP Security System in 2006. Since 2007 he works as head of research and development for the German web application company SektionEins GmbH that he co-founded. In 2010 he did his own ASLR implementation for Apple's iOS and shifted his focus to the security of the iOS kernel and iPhones in general. Since then he has spoken about the topic of iOS security at various information security conferences around the globe. In 2012 he co-authored the book the iOS Hackers Handbook.
