MDM Profiles on macOS

Notes: From Zeno Popovici with edits & tested on a M1 macbook with Ventura (macOS 13).

In macOS you can check the MDM status with the following command in a Terminal:

profiles status -type enrollment

Non-removable MDM profiles cannot officially removed without doing a full system wipe

Add LUKS2 support to GRUB bootloader UEFI image

• Assuming a Linux live or rescue system is booted and the new soon-to-be root encrypted partition is accessible on an NVMe drive, 2nd partiton (/dev/nvme0n1p2).
• The EFI partition is the first on the device (/dev/nvme0n1p1).
• There is no extra /boot partition since it should be encrypted as well and is included in the partition mounted as root / later.
• The following requires root privileges, a preceeding sudo -i is assumed.

Inspired by: https://askubuntu.com/questions/1397826/default-embedded-modules-in-bootx64-efi-grubx64-efi-and-mmx64-efi/1466507#1466507

Python+Miniforge+JupyterLab Install and Update Guide for Windows

• For a unprivileged user, without administrative rights
• If a window, asking for an (admin) password pops up during installation or when installing any packages, just ignore it by closing the window. The installers should switch to user-mode then.

Install

1. Search for Miniforge in the Internetz or download from here directly: https://conda-forge.org/miniforge/
2. Install Miniforge for the current user only
3. Create a dedicated environment for Jupyter Lab:

for fn in *.JPG; do
    echo "=> $fn"
    # get the timestamp from exif, format it accordingly
    ts=$(exiv2 -g DateTimeOriginal $fn | awk '{ts=$(NF-1)"_"$NF; gsub(":","",ts); print ts}')
    # retrieve the base name as well
    basen=${fn%.*}
    # rename the image, append its original name
    mv -i "$fn" "${ts}_$basen.jpg"
    # check if there is video file with the same name (live mode)
    if [ -f "$basen.MOV" ]; then

fn="$1"
echo "fn: $fn"
[ -f "$fn" ] || exit 1
str="$(exiv2 -p a "$fn" 2>&1 | grep -a Exif.Image.DateTime | grep -a -o '2019:.*$')"
#echo "'$str'"
# fix datatime first
exiv2 -M"set Exif.Image.DateTime $str" "$fn"
# extract all readable metadata (to .xmp file)
exiv2 -eaX "$fn"
# delete all metadata

# It initiates decryption of the root device which contains
# LVM with BTRFS on the root volume where grub is installed.
# Therefore, it allows to load grub from an LUKS encrypted BTRFS
