@george1421 thanks for your reply, i will retest as per your instructions

@saftkartoffel going by your photo i am experiencing a very similar if not identical issue, attempting to capture an image from a 2020 MBA using usb key booting with bzImage.T2 (renamed to bzImage)

Issue : When Image Capture is performed FOG captures image of UEFI USB Boot Key by default (Host MacBook Air 120 Gb SSD not visible to FOG ?)

Test Environment :

MacBook Air (Retina, 13-inch, 2020), Model A2179
Serial Number: FVFCW0PYQ0WN
macOS Catalina (Version 10.15.3)
T2 chip disabled
MAC address 00:24:32:17:46:49 (from USB-C to Ethernet Adapter)

CentOS 8
Linux c8-fog-server 4.18.0-193.14.2.el8_2.x86_64 #1 SMP Sun Jul 26 03:54:29 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

FOG Project 1.5.9-RC2 running on CentOS 8
You are currently running version: 1.5.9-RC2
bzImage Version: 5.6.18
bzImage32 Version: 4.19.123

Using UEFI USB boot key as described in forum post (George’s half official USB boot method)

• USB boot keys generated using above process function correctly on all wired Ethernet MacBook / Mac Mini / iMac, also MacAir (Thunderbolt to Ethernet) / MacAir (USB 3 to Ethernet adapter)

USB-C to Gigabit Ethernet adapter, successfully obtains ip address from FOG server DHCP and displays FOG Project menu

performed “Quick Registration” of host “MacAir_2020” - exit / restart of system generates kernel panic on shutdown

attempted capture of image from host “MacAir_2020”, FOG appears to capture image from GRUB USB boot key (creates 120 Mb image) by default

tested using “bzImageT2” kernel provided by moderator “george1421”
(copied to /var/www/html/fog/service/ipxe as per instructions)
referenced in Host General - Host Kernel for host “MacAir_2020”

manually created host “MacAir_2020” referencing bzImageT2 as above, same status when testing image capture

“MacAir_2020” Host General - Host Primary Disk - setting not specified (suggested entry?, any entry in field appears to be overwritten, defaults to /dev/sda1)

Any suggestions / recommendations would be greatly appreciated. I can provide additional configuration information if required. Many Thanks
