Installing IPAs on Apple Silicon (M1)

Open Apple Configurator 2 and plug in your iPhone or iPad
Click Add, login to the App Store and select the application you want to install
Open up ~/Library/Group\ Containers/K36BKF7T3D.group.com.apple.configurator/Library/Caches/Assets and wait until the TemporaryItems directory appears
Copy the application from the newly created temporary directory, but do note that it will disappear once Apple Configurator is done installing
Double click the .ipa on your Apple Silicon (M1) device and install it
Fix permissions on the installed application by running sudo xattr -rd com.apple.quarantine /Applications/<your_app>.app (if you skip this step, you're unable to start the application)

Note that it's easier if you already have the application installed, as Apple Configurator will prompt you about overwriting the existing installation, at which point the temporary file (the .ipa) will still exist, until you choose an action in the prompt.

Scenario

You're running a KVM-based virtualization. You want to do PCI/PCIe passthrough of some device. You don't want it to attach to the host OS at all.

Your device looks like that:

00:1f.2 SATA controller [0106]: Intel Corporation 6 Series/C200 Series Chipset Family SATA AHCI Controller [8086:1c02] (rev 05)
	Subsystem: Hewlett-Packard Company 6 Series/C200 Series Chipset Family 6 port Desktop SATA AHCI Controller [103c:330d]
	Kernel driver in use: ahci
	Kernel modules: ahci

Proxmox Assign Bind Mount To Unprivileged Container

In order for the LXC container to have full access the proxmox host directory, a subgid is set as owner of a host directory, and an ACL is used to ensure permissions.

Bind Mount dataset to LXC

Add the following line to /etc/pve/lxc/<CT_ID>.conf

mp0:/mount/point/on/host,mp=/mount/point/on/lxc

Create group on host

In the default Proxmox configuration, unpriviliged container subgids will have the prefix "10" followed by the expected 4-digit gid.

	# enable AMD IOMMU with DMA passthrough
	# note: iommu=pt is much faster than the default translated DMA since memory access doesn't need to go through the hypervisor
	sudo sed -i '1 s/$/ amd_iommu=on iommu=pt/' /etc/kernel/cmdline

	# list IOMMU groups
	# record the PCI IDs of all devices in the target group
	for d in /sys/kernel/iommu_groups//devices/; do

	n=${n%%/*};
	test $n -eq $pn \|\| printf '\nIOMMU Group %s\n' $n;
