TonewoodUpdateForOSX 64-bit app?

 When will the 64-bit version of this app be released so those of us upgrading to Catalina won't be left out of the next TWA firmware release?

We're currently working on getting the update utility ready for compatibility with macOS Catalina.

Nicholas, any progress or ETA?

Any update?  We need this....

Hi, all! The 64 bit compatible updater is live at

If you have any questions, please reach out to me at

Thanks for this! You can ignore my support request, as the first page I went to didn't have this file.  It took me about 6 different micorusb cables to find one that would work, but when I found a good one (it was very large guage, but all I tried had 6mm length including the one that worked), it worked great.

You're welcome! I'm glad you've successfully run the update!
