Greetings all and Happy New Years Eve -

Was hopeful that someone can point me in the right direction. I use an iMac for my daily driver, which has macOS Catalina on it.

I downloaded the ReadSpeed files that were specific to Mac and then used BalenaEtcher to create what I thought was going to be a bootable USB. When I restart Mac by holding down option key to select an alternate boot device, the ReadSpeed USB is not there.

When I look at the file on the USB, it shows 2 of them PCI.EXE and RS.EXE

Any help is appreciated.

Thanks
Jay
 
Hey Jay. There are a number of DOS-specific hidden files that you won't see in the Mac Finder. Just restart your Mac, and hold down the Option key once you hear the startup chime. You'll get a list of bootable images, just arrow over to the one labeled Windows.

If that doesn't work, this is an excellent article about booting a Mac into DOS:

It seems people have been finding that Macs that used to boot Windows off USB will no longer do so. This may or may not be tied exclusively to Big Sur and/or the new Apple notarization feature (signing apps.) Don't be surprised if you have trouble or even the inability to get it to work.

How old/new is your iMac?
Does it have a cd/dvd player?

Thank you for pointing me to the article.

"Don't be surprised if you have trouble or even the inability to get it to work." - yeah the never ending story of the Mac!
