G-Speed Software Utility opens no windows

My G-Speed Shuttle XL TB3 connected to iMac Pro suffered a power supply failure a few months ago (there was no power failure on the grid). During the troubleshooting period the software utility launched but no windows opened. The menu bar only showed G-SPEED Software Utility | Window | View | Help, and both Window and View menu items were grayed out. Hence, I couldn’t read any disk health data using the utility, nor read the logs.

WD gladly replaced the enclosure for me, and the disks mounted without any rebuilding process (as far as I could hear). But the software behavior remained the same, even after reinstalling. I thought the enclosure might have corrupted the logs of the software, so I trashed the application again and deleted everything that I could find that contained WD, HGST and G-Speed:
Macintosh HD⁩ ▸ ⁨Library⁩ ▸ ⁨Frameworks⁩ ▸ ⁨GSpeed2.framework⁩
‎⁨Macintosh HD⁩ ▸ ⁨Library⁩ ▸ ⁨Frameworks⁩ ▸ ⁨libcurl.framework⁩

After reinstalling, the software still doesn’t open any windows. On a Macbook Pro, the software works though.

Any idea how to perform a clean removal?

BTW, I think the software is dumping error logs in the root directory, if that helps:

In the software menu at the top click on check for updates and it should run a software and firmware update and it should solve the issue.

Also just to make sure you have the correct software you need this one: G-Speed Shuttle TB3 Software Utility

I’m having this same issue, but check for updates says everything is up to date. Running on macOS 10.13.6 just download the app for the first time, it launches but no windows open. Any thoughts?


I’m running on 10.15.7 now (Catalina) and just updated to G-SPEED Software Utility ver 2.00.5200.32. This version also provides a firmware update. All seems to run normally again.
