Support SD Card Slot

[seangineer]

Add support for attaching an SD Card through the built-in card reader in some modern Macs.

Currently, when plugging something into the slot, it is not exposed by UTM, i.e. as a USB device to attach to the guest. For some context, my use case is working with non-MacOS native file systems, such as files on an SD card intended for a Linux single board computer.

For reference, I am using a 2021 14" M1 Pro MacBook Pro.

precisely what I'm trying to do... any workarounds in the meantime? :/

same I need to access sdcard

QEMU supports this but I doubt Apple's virtualization framework supports it. I cannot find anything that would enable such a feature in their docs — see the device types documented here: https://developer.apple.com/documentation/virtualization/vzvirtualmachineconfiguration#3667140 I'd love to be proven wrong though.

yeah I was reading around the web and is something from Apple that prevents VM to read it. I just bought a cheap SD-CARD reader to usb-c and it works on UTM I can read the sdcard

My workaround for access to an ext4 sd card is to create an image of it:

# get the disk with 'diskutil list'
dd if=/dev/disk4 of=~/Desktop/dump.img
# pwd = ~/Desktop
brew install qemu
qemu-img convert -f raw -O qcow2 dump.img dest.qcow2

then create a new disk for the machine in UTM and import the .qcow2 file. I suppose etcher can write it back to a card, but i haven't tried that

QEMU supports many models of SD card slots, for now adding support for virtual sd cards would be nice.

Just try to edit a Raspberry Pi SD-Card with UTM and Gparted Live and was stuck here.

An external USB card reader will do the trick until this bug is fixed.
