pp611 Posted May 16, 2022 Share Posted May 16, 2022 Since I upgraded to Monterey I can no longer using the external USB-C display and two-way AirDrop, I decided to try to install Big Sur into a flash drive and run from the drive as well. I picked up the SanDisk Extreme SDCZ880-256G drive. Installation was smooth, with two reboots to run from the intermediary MacOS Install partition, and eventually boot menu showed the name of the assigned drive to which Big Sur was installed. But the boot process always stopped at the lines Waiting for DSMOS... ALF, old data swfs pid _entry (ptr), updaterules_msg (ptr›, updaterules_state (ptr) The booting always stops here, no matter the booting OpenCore is from the USB installer, or the system SSD, or the target flash drive. The same OC configuration, along with the drivers and kexts, can boot a Monterey installed on the system SSD drive fine. Anyone has experience of running MacOS from flash drives?

coolcatco888 Posted August 25, 2022 Share Posted August 25, 2022 You might need to include the OpenCore driver for reading from USB drives, OpenUsbKbDxe.efi.
