Installer runs and finishes...but Rockbox not installed

[Head_Unit]

I'm tired of my Sansa Clip Zip's firmware, which seems to end up eating a LOT of space and getting corrupted occasionally.

But when I try to install Rockbox, it doesn't work.
- I have Rockbox utility and when I open it I can see the Clip Zip and the (Mac OS Yosemite) mount point fine.
- Checked are Bootloader, Rockbox, Fonts, Themes.
- Clicking Install ask me for the Sansa file (clpza.bin)
- Install proceeds and the dialog box shows all OK, ending with "Package installation finished successfully"
- Bootloader is now unchecked; Checked are Rockbox, Fonts, Themes.
- Clip Zip does not reboot itself.
- Eject button yields "Ejecting the device failed. Please make sure no programs are accessing files on the device. If ejecting still fails please use your computers eject funtionality."
- Ejecting from Mac Finder makes the Sansa "Refresh your media"
- The usual Sansa interface comes up, with no Rockbox logo in sight.
- Shutting down and turning the Clip Zip back on does nothing
- Repeating all the above did not help.

?!?!?!?

Please check the mountpoint selected in Rockbox Utility. This behaviour usually appears if the wrong mountpoint is selected. It will then install Rockbox to the wrong drive (which doesn't cause any harm), but obviously the actual player won't notice about it.
