I hope you all can help me out. I have an ASRock B450 Pro4 motherboard with latest BIOS, AMD Ryzen 7 2700x CPU, RX480 video card with 8GB, 32GB system RAM. I followed the guide at Dortania, made the USB stick with Windows Rufus method, got the install files with open core for Big Sir with python macrecovery.py -b Mac-42FD25EABCABB274 -m 00000000000000000 download. My boot-args are -v keepsyms=1 debug=0x100 alcid=7. My install keeps stopping at Using Default RecoveryOS logarchive preservation timeout then Could not create path /private/var/MobileSoftwareUpdate/restore.log: Read-only file system (see attached image)
