Why is it so hard to create a bootable USB for Mac Sonoma?
Since installing an auto Sonoma software upgrade my Mac M1 has become painfully slow at start up taking a minute or more! I am trying to solve the problem with a clean install of Sonoma.
I have tried multiple times to create a boot disk for Mac Sonoma.
It looks easy on the various Youtube videos but my experience is the opposite.
I have checked terminal permissions, I have downloaded Sonoma multiple times to make sure the Sonoma installer is not the issue. I have followed the procedure recommended by Apple to format the USB disk labeled MyVolume and the recommended terminal command....
Observations:
- A 16gb memory stick is too small
- Different opinions on how the USB stick should be formatted including APFS which doesn't work!
- I have followed the recommended USB configuration and terminal command provided by Apple Support. However it doesn't seem to work on my Mac M1 Studio.
The command line process kicks off ok but I always end up with the same error. Here's a dump:
Erasing disk: 0%... 10%... 20%... 30%... 100%
Copying essential files...
Failed to write .IAPhysicalMedia cookie to disk. Error Domain=NSCocoaErrorDomain Code=513 "You don’t have permission to save the file “.IAPhysicalMedia” in the folder “Install macOS Sonoma”." UserInfo={NSFilePath=/Volumes/Install macOS Sonoma/.IAPhysicalMedia, NSUserStringVariant=Folder, NSUnderlyingError=0x600003f6ebe0 {Error Domain=NSPOSIXErrorDomain Code=1 "Operation not permitted"}}
The bless of the installer disk failed.
There seems to be some sort of terminal permissions issue???
And just to make life more interesting I can't even boot the Mac into recovery mode because my Logitech keyboard is not recognised during start up! It seems I have to purchase a USB Keyboard and mouse.
The joys of modern technology!
Advice appreciated.
Mac Studio, macOS 14.5
