Similar issue observed by one of my students. No file appears in the browser.
OS: macOS Monterey 12.1

Screenshots of the situation:

Workaround: drag-and-dropping a file from the desktop into the bar on top of Gephi (where the three buttons "Overview" etc. are) allows opening the files.

I confirm this happens on my Mac (12.3.1). Still not tested on Windows and Linux

It happens on my wife's Mac desktop and MacBook Air. Both running 0.9.2 now. I have tried drag and drop on the Mac desktop to the empty area in the window and it does not work. Have not tried the bar though.

Edit: Just tried on another MacBook Pro. Same problem. Drag-and-drop to the bar works. Thanks!

Thanks, we'll investigate what the root cause might be. We (Gephi) don't control this window it might be a JRE or Netbeans problem. I wonder if we could be more precise how to isolate the problem:

1. Does it happen every time?
2. Does it happen with every folder?

So far I haven't been able to reproduce it locally (12.2.1). Yet.

I have tried with three Macs (an all-in-one, an MBP and an MBA) all with Big Sur installed. It happened every time. Tried many directories, but most of them have nothing listed with "all files" selected. The only exception I found is a directory with a bunch of .pkl files (Python object serialization files) listed.

Thanks, I'm researching and it may have something to do with security preferences on Mac OS. Can you please try the following and let me know if that works:

1. Launch Gephi Application from a terminal: /Applications/Gephi.app/Contents/MacOS/gephi
   or
2. Go to Mac OS Preferences > Security & Privacy > Privacy > Full Disk Access > Add Gephi there.
   Thanks!

Tried this way, still not working.

(macOS 12.3.1, M1 Mini)

Confirmed @jacomyma 's work around is working for me. Thank you.

@mbastian
I have tried both on my MBP. The first method solves the problem. Files are listed correctly. The second method makes no change. Still not listing files. Thank you for the suggestions!

I have done more tests. It seems that certain types of files can be listed in certain directory. Everything in the Download directory is not listed. Certain file types including .csv, .jpg, .mp4, etc. can be listed in some directories. It is very random.

Thanks for the inquiry. I found the root cause and I'm working on a fix.

Netbeans ran into the same issue and fortunately provided a solution. I'm looking into how to integrate this solution as well.

As a reminder, there are two workarounds:

1. Drag the file into the top bar (Overview, Data Laboratory etc.) to open it
2. Launch Gephi Application from a terminal: /Applications/Gephi.app/Contents/MacOS/gephi

Hi folks, we've made a fix that should solve this problem. Could you please download and install the nightly build and let me know if that solves the issue:
https://oss.sonatype.org/service/local/artifact/maven/content?r=snapshots&g=org.gephi&a=gephi&v=0.9.4-SNAPSHOT&c=macos-x64&p=dmg

I have just tried it and it works well! Thank you so much!

Thanks, we'll release a new stable version (0.9.4) soon that will include this fix.

Thank you @mbastian . It works now!

Hi all, the 0.9.4 version of Gephi has been released. Please download this new version to resolve this issue. Thank you!
