I downloaded the Catalina dmg file and used TransMac free trial to build a Catalina usb installer. However, I received this error (could not write to mac volume) when trying to write the file to USB drive. Any other option left other than TransMac?

A must do! You must format hard drive for mac giving it a title that you will again use same title when creating the usb installer. The title hard drive must match the title of the usb installer.

The hard drive has to be formatted also for a Mac to install the usb installer.

Are you formatting for mac before you try restoring with disk image?

Yes, we you right click over the usb drive you have an option of formatting for a Mac, after that has finished, right click on usb drive again and select restore image and go to the dmg file and when finished it will be ready for booting up on a Mac installer.
