The best way to use the Advanced Uploader is to use Firefox ESR on Mac. By using Firefox, the user can upload any user’s folders on Mac by default without changing any settings.
Advance Uploader doesn’t work with Chrome as Chrome doesn’t support JSF.
If you want to use Safari on Mac, you need to change the following settings:
1) On Safari, click menu Preferences
2) Click Security tab, and then click Plug-in Settings at the bottom of the window
3) On the left panel, select Java, and select the Allow Always.
4) Click Done to save. Now if you start Advanced Uploader in Safari, you can browse and upload your folder.
