Installation stuck in a loop : Mac OS Sequoia on a HP Elitebook 850 G6

[timmermanso]

Hello everyone,

I am trying to install Mac OS Sequoia on a HP Elitebook 850 G6

Computer: HP HP EliteBook 850 G6
CPU: Intel Core i5-8365U (Whiskey Lake-U, V0)
1900 MHz (19.00x100.0) @ 3779 MHz (38.00x99.5)
Motherboard: HP 8549
BIOS: R70 Ver. 01.32.00, 03/07/2025
Chipset: Intel Cannon Lake-U PCH-LP Premium
Memory: 16384 MBytes @ 1193 MHz, 17-17-17-39
- 8192 MB PC25600 DDR4 SDRAM - Micron 8ATF1G64HZ-3G2J1
- 8192 MB PC25600 DDR4 SDRAM - Micron 8ATF1G64HZ-3G2J1
Graphics: Intel UHD Graphics 620 (Whiskey Lake-U GT2) [Hewlett-Packard]
Intel UHD Graphics 620, 8174738 KB SDRAM
Drive: INTEL SSDPEKNW512G8L, 500.1 GB, NVMe
Sound: Intel Cannon Lake-LP - cAVS (Audio, Voice, Speech) [B1]
Network: Intel Wireless-AC 9560 160MHz
Network: Intel Ethernet Connection I219-LM


I can start the computer on the USB key, create the Macintosh HD partition and start the installation without issues since I replaced the NVME disk.
The installation seems proceeding well (time going down) untill it reaches a first reboot.
Then it starts rebooting to installation page. I can select Mac OS Installation => Leads to a loop or Mac OS Recovery => Leads to a new installation.

Here is my efi folder.
Can someone help me ?

Set SecureBootModel to Disabled and then try to format the drive again and then perform the installation.
