Talking about USB sticks, the first time I made one for Sonoma with createinstallmedia, I got this error in the Terminal: /Volumes/USB16GB is not large enough for install media. An additional 148,1 MB is needed. This after formatting it as macOS Extended (Journaled) and with a GUID partition map. So I had to use a bigger USB flash drive. Today, I tried again, but starting with a MS-DOS with Master Boot Record USB stick: which resulted in slightly more free space and was accepted without complaints by createinstallmedia, which erased the disk and proceeded. Strange, this different behaviour, due to the Sonoma beta installer being slightly bigger than the previous ones. Of course, in this way the USB stick remains formatted with MBR, instead of GUID: certainly not the most ideal solution, considering that you cannot install OCLP on MBR. So, in order to use GUID, it looks like a 32 GB USB flash drive is needed, at least in my case (SanDisk Ultra)…
