FlashWizard is another one of my personal-use apps that I decided to share with everyone. It's simple, straightforward, with no unnecessary steps or gimmicks. While there are plenty of apps out there that do the same thing create a bootable macOS drive FlashWizard can be another excellent option. With just a few clicks, you can turn your USB drive into a bootable installer, ready to install or restore macOS.


Why use FlashWizard?


    •    Simple, Intuitive, and Straightforward: No nonsense, no unnecessary steps.
    •    Fast: The flashing process is optimized to be as quick as possible.
    •    Supports multiple macOS versions: From macOS Mojave up to macOS Tahoe, it gets the job done.
    •    Secure: Uses macOS's built-in Authorization Services to ensure only user-approved commands are executed.
    •    Logs: You can find output and error logs in /tmp (note: the files are hidden).
There are still a few features to be implemented in the future. For now, if you can test it and give me feedback, I promise to reply as soon as possible. Suggestions are welcome as long as they're useful for everyone and not just personal preferences.


How to Use:


    •    Step 1: Select the macOS installer (by clicking the icon this applies to all steps).
    •    Step 2: Select your USB drive. A 16GB drive is enough to create a bootable macOS installer from version 10.9 (Mavericks) up to 13.7 (Ventura). For later versions, I recommend a 32GB drive. If you choose to format the USB, it will be formatted as JHFS+ with a GUID Partition Map.
    •    Step 3: Click Flash macOS to USB and wait. Don’t worry if an error occurs a message should appear (at least I hope so, LOL).

Download version 1.0.1  the app is now notarized, and you won’t see that annoying alert anymore.

Hey @Mirone, thanks for the app! I've just downloaded the 1.0.1, started using it for the Tahoe, and on the final step, I've got the message of error. I can't remember the progress percentage that was done but here's the screenshot, and I'm on Sonoma, if that helps.

 

I don't know if the process was successfully done and it just a bug message, or it's really something goes wrong during the process of copying the files!

Thank you for downloading and testing the app! Open the menu and go to the logs; they are hidden. See if the error log shows anything. Did you try booting from the media created after the installation?

I did it, and it opened tmp folder that have 3 folders inside, but unfortunately no log file was there, the folders was empty!

Did you try creating the media again and encounter the same error? If not, could you try again?
