Install Disk Creator for Mac1.5

It work for me once. Now I as stuck on my second attempt. An error occurred. Try ejecting the destination disk and reinserting it, or rebooting. It probably couldn't be unmounted to erase it. I've tried with different new USB's...it's driving me crazy!

perfect for me wth a sd card and Big Sur systèm for a MacBook M1

If you're not afraid to use the Terminal app, see <https://support.apple.com/en-us/HT201372>.

I needed to downgrade my wife's Late 2013 Macbook Pro from Catalina to High Sierra after replacing the SSD. Catalina seemed to cause problems, especially with the trackpad that seemed to stop working/ lag. I tried many other apps and terminal commands to create a bootable USB and Disk Creator was the only one that actually worked.

Refused to make a bootable flash drive of Sierra with fresh install and freshly erased drive.

I KNOW its free and a really GREAT app BUT Catalina has been out both in ß and final version for a long time. As a premier app, we REALLY need a Catalina specific version, PLEASE

Im a software tester myself, and agree that there should be some sort of progress bar. I made my own progress bar, kinda, by doing a get info on the installer as it was being built. You can see the size continue to increase over time. Maybe the dev can build a progress bar from that. Thanks

Buggy with Catalina - Help please developer!

What Apple obfuscates and makes difficult, great devs make simple. Thank you. Everyone, please chip in when you can!

This app is a butt saver! As an active beta tester I cannot count the times that I have used this marvelous app to create installers that I store on Flash Drives and always have available when that moment arrives and you have an emergency and must reinstall your system. There is no need for an Internet connection for the reinstall incase your Wifi has crashed or is simply not available. As far as periodic reinstall issues as scorned by chasjunk in his review it IS a good idea every few months reinstall. Periodically there are small corruptions in the OS that cause little irritations that are near impossible to isolate. There are apps that sometimes do not get along with others that even after uninstalling leave issues and a new OS reinstall will often correct. By the way if you have an installer on a Flash Drive with3.0 speed capabilities it is faster than going to online recovery!
