FIJI crash when starting - Mac OS X 10.10

Hi, I cleaned my Mac (free space) and now when I try to open FIJI I have this message:

I already tried to download FIJI again but I received the same error message…

Any idea ?




That is weird. Usually a fresh download/install is the best bet…

But I think you might be trying to ‘run’ the wrong thing… You should just save “Fiji” in your Applications folder and run it directly there - just double-click or right click and then “Open”. No need to “Show Package Contents” to dig further… ie - don’t try to run “ImageJ-macox” in the “Contents/MacOS/” folder.

Should look just like this:

Thanks but even doing like that it’s not working… Interestingly I upload ImageJ and it works well… I just have this error message with FIJI ! Clearly hav no clue to what happen… :-/


Try another fresh download/install of Fiji - download from here:

Then try again what I said… making sure the Fiji app is in the Applications folder… and that you just double-click the icon. You may get a ‘warning’ that pops up saying it’s downloaded from the internet and might not be ‘safe’ - but it’s fine… just proceed.

Otherwise - @ctrueden - any ideas on on this one??

Ok… Just did it… I though it has work… and then same error message :sweat: I really don’t understand… And of course it happen right NOW, when I have plenty of time with the confinement to develop my knowledge on FIJI !!! :weary:
But thanks so much to try to help ! If anybody else has an idea… Maybe I remove something that FIJI need when I clean my Mac memory… ???


I honestly don’t know what else to try at the moment… perhaps others here can help? @ctrueden @imagejan - any ideas?

What version of Java are you running? Perhaps you need to reinstall Java? I have no idea if this is causing the issue here… but good to check.

I would try two things next:

  1. Try launching Fiji with a different version of Java. You could try the JBRSDK8 and/or JBRSDK11 from here.

  2. Try the latest UNSTABLE version of the ImageJ launcher from here. This replaces the Contents/MacOS/ImageJ-macosx executable.

@PIC Please let us know if either one of these things avoids the issue! Or if you need more guidance on how to proceed.

Ok, sorry for this long silence but I tried several things… So, here I’m: I tried to download back Java (last version) = doesn’t work. Then I uninstalled Java as it is recommended and even there I had trouble with a new error message… I contacted Oracle team and they tell me to do what was recommanded on the website and that I already all tried and doesn’t work…
So I decide to reboot my Mac… I think I have done something wrong when I tried to free space and delete an essential folder…
Thanks a lot for all your efforts to help me. It’s really appreciated to see that some people care to your problems ! :wink:
I will keep you in touch if the reboot works !
Have a nice and safe day !
