Starting the Fuse Dashbord app on OS X, CPU use jumps to a constant 25%, heating the machine, spinning the fan and draining the battery, even before interacting with the app, and after quitting the app with Cmd+Q. Running “killall Fuse” from the terminal returns CPU usage to around 0%. How to solve this? ---

Hi! Thanks for reporting this. Can you give us some more details about the system you are using please? (and what Fuse version) ---

- MacBook Air 1,7 GHz Intel Core i7 - 8 GB 1600 MHZ DDR3 - Intel HD Graphics 5000 1536 MB - OS X 10.11.1 - Fuse version 0.9.2 (build 5183) The CPU usage is not reflected in the processes in Activity Monitor. It just says “User: 25%” in the bottom, even though no processes on the machine takes more than a few percent. Also, when opening projects, “nothing” happens. The project doesnt show in “Recent projects” so I can’t run the Preview window from Dashboard. Workaround using `fuse preview` from terminal. Don’t know if this is relevant or another bug. ---

Hi Olav, Can you please see if the file `~/.fuse/user_data.json` is present on your system? If it is, could you please send it to us? If you upload it to [https://www.dropbox.com/request/Rx1QN3QluvxAJiyGJqrh](https://www.dropbox.com/request/Rx1QN3QluvxAJiyGJqrh) it is only accessible for the Fuse team. ---

The `.fuse` directory contains only `logs/fuse.log` which is practically empty. If you’re interested I can drop by your offices today to make debugging easier. (I visited Bent last week.) It would be helpful to solve this as I plan to sit down with a friend and get up to speed on Fuse all day tomorrow. Also, how do I get an email whenever someone responds to my forum postings? Couldn’t find any settings for this in my profile, and one can’t be expected to go in and check this manually on a constant basis. ---

That might be very helpful! We are however investigating both of your issues right now, so it might be that we solve them earlier. If not, it would be great if you could drop by. In the mean time, could you please try a few things? - Paste the output of `ls -la ~/.fuse`. I’d like to verify that you have write permissions in that directory. - Do you have several users running Fuse on that computer? What does `ps aux |grep -i fuse` say? - Can you try to close all Fuse windows and quit Fuse from the menu bar icon, do `ps aux |grep -i fuse` and finally `fuse daemon`, and paste the output from both of those commands? There is unfortunately no way to subscribe to forum thread updates at the moment, but I think that feature is coming very soon. ---

Hi Olav, feel free to drop by if you want! 🙂 We’re here for a few more hours today, and tomorrow too. However, I think I’ve found the problem, your `~/.fuse` is owned by root. That can be fixed by ```auto sudo chown whoami .fuse ``` It would be interesting to see if that also fixes your CPU usage, it might be that something is busy-waiting on writing to that directory. ---

Thanks for dropping by! 🙂 For the record, fixing the directory permissions solved both the issue with missing recent projects and CPU usage. ---
