create bootable usb macOS Catalina

[the_armiger]

Hello all,

I am trying to follow this guide https://forums.macrumors.com/thread...installation-of-macos-10-15-catalina.2205092/ but whenever i am in this step shown in the image it gets forever stuck at 0%.

Any ideas?

Is on a MacBook air early 2015 13 inch with MacOS monterrey, on a 64 gb usb.

Thanks in advance

OP:

Instead of fooling with terminal, try this FREE utility, "Install Disk Creator":

Make a Bootable USB macOS Installer Download the update for Big Sur compatibility -

What’s needed for a clean install on a Mac A backup of the disk before it’s erased. Two options are to use Duplicate (a free utility which can copy and paste an entire bootable volume), or Mac Backup Guru (a paid, fully featured backup utility with unique incremental backups capability) for...

It should create the bootable installer with a few clicks of the mouse button.

Please get back to us if it works.
