Transmac on Windows 11 to create bootable flash drive for High Sierra 10.13

[Ztruker]

Trying to install High Sierra 10.13 on a Mac donated to my church Thrift Store, which is what this Mac requires.
I'm using Transmac under Windows 11 as I don't have a working Mac to use to create a bootable USB Flash drive.
I downloaded the High Sierra 10.13.iso from Internet Archive and used that as input to Transmac to create the flash drive.
It completed successfully but and when I power up the Mac while holding down the Option key, it recognized the flash drive as
High Sierra and allowed me to start the install but it fails after a few minutes.

I can post the Install log here if that would be of any use.

Looking for suggestions on how to proceed.

Have you tried holding Command-R while powering the Mac up to see if it will boot into the recovery partition? If that works, you should be able to reinstall whatever version of macOS was last installed on the drive. If that doesn't work, holding Option-Command-R while powering up should boot into internet recovery and allow you to install the latest version of macOS that's compatible with the hardware. You'll be prompted for Wi-Fi credentials, but if the Mac has an ethernet port that should work too. The download can take a long time.
