Just tried on Senoma Sat doing nothing

[FredGannett]

App started and selected target location, put up "writing test files" diaglog box but just sat there doing nothing.
Other apps and the finder can write to the drive being tested. F2XSwift version 1.0.3 (7)
After doing brew install f3write - could make files on the device.

When looking in Xcode the project would not compile because the developer was not assigned to an Apple_id. This is probably compulsory now. This was quite simple to do but probably needs to be put in the readme.
Thanks !!

When running the f3build binaries directly I get this pop up that could explain matters ....
