I have a running Raspberry Pi image. Now I want to do the following:
In Disk Utility I see the partitions disk1s3 and disk1s6 but can't mount them from there:
Found this article -> Mount a Raspberry Pi SD card on a Mac (read-only) with osxfuse and ext4fuse, It worked like a charm.
Here is the commands I ran om my mac:
brew cask install osxfuse
brew install ext4fuse
sudo mkdir /Volumes/rpi
sudo ext4fuse /dev/disk2s2 /Volumes/rpi -o allow_other
sudo cp /Volumes/rpi/home/pi/Pictures/* /Users/me/work/raspi/Pix/
I had some issue with permissions, but could copy with sudo.
cheers
could not copy extended attributes error while copying files, you can use rsync instead as mentioned here: sudo rsync -r /Volumes/rpi/path/to/src/dir path/to/dest/dir
brew install macfuse now and you have to disable the warning that FUSE is no longer open source by brew edit ex4fuse and comment out the on_macos do line with #disable... then you can continue with above.
brew install ext4fuse gives me Error: ext4fuse has been disabled because it requires closed-source macFUSE!

Read and write Linux SD card on MacBook M1 with USB-C.
Install UTM: brew install utm
Run ArchLinux ARM in UTM.
Plug SD card into USB-A adapter.
Plug USB-A adapter into USB-C adapter.
Plug USB-C adapter into your laptop.
Allow access to the USB device for UTM:
Get the new device id: fdisk -l.
/dev/sda2 532480 249737215 249204736 118.8G 83 LinuxMount the new device: mkdir /sdcard && mount /dev/sda2 /sdcard && ls /sdcard
Unmount when done and g2g: umount /sdcard
I'm very surprised myself but this works.
Download the "Apple Pi Baker App" and use this software to transfer an image to your SD card or backup an image to an image:
AFAIK there's only one way to mount Extfs on a Mac and that's via Paragon Extfs for Mac
It's commercial software but they do have a 30-day trial. Works great for me.
As noted by Gotschi you can't mount an ext4 partition on the Mac, but you can backup the SD.
The following is a script I use. This uses diskutil to find a disk with a Linux partition to automatically find the SD card.
NOTE This takes quite a while to copy!
#!/bin/bash
# script to backup Pi SD card
#DSK='disk4'
export DSK=`diskutil list | grep "Linux" | cut -c 69-73`
if [ $DSK ]; then
echo $DSK
else
echo "Disk not found"
exit
fi
diskutil unmountDisk /dev/$DSK
echo pleae wait!
sudo dd of=~/temp/Pi/Piback.img if=/dev/$DSK bs=2m
echo backup completed - now compressing
gzip -9 ~/temp/Pi/Piback.img
#rename to current date
mv ~/temp/Pi/Piback.img.gz "~/temp/Pi/Piback`date +%Y%m%d`.img.gz"
Unfortunately, you can only mount the ext3 (disk1s3 & disk1s6) partitions with 3rd party programs (maybe some FUSE module)...
I tested mounting the SD card in a VM, but the SD card reader seems not to use a USB connection internally, instead it is directly connected to another BUS. (I only tried VMware Fusion, maybe parallells gives you better options)
you can either backup the whole SD card (results in a 16gb file):
sudo dd if=/dev/disk1 of=~/Desktop/SD.img bs=1m
or a certain partition:
sudo dd if=/dev/disk1sX of=~/Desktop/SD.img bs=1m
where X is your partition number if it gives you a Device busy error, be sure to "deactivate" all partitions on the SD card in the Disk Utility.
Edit
after backing up, you may save a LOT of space when you compress the .img
for e.g. editing the config.txt on a home assistant OS installation I use
mkdir /fat_mount
mount -t msdos /dev/diskXXX /fat_mount
as advised here to mount the FAT disk
