Fiji OS X Mojave installation

[kmiddleton]

I'm running OS X 10.14.2, and I am receiving the "To open Fiji you need to install the legacy Java SE 6 runtime" message each time I start. I installed Fiji using the bundled version from https://imagej.net/Fiji/Downloads. Separately, I also tried installing the Java 8 runtime and the nojre version (which gave the same result).

Strangely, a different machine, also running Mojave, worked fine.

Are there suggestions for troubleshooting this problem?

Thanks,
Kevin

I suspect you are running into the dreaded macOS Path Randomization problem.

    https://weblog.rogueamoeba.com/2016/06/29/sierra-and-gatekeeper-path-randomization/

Path Randomization is in effect if “ImageJ home:” starts with "/private/var/folders/“ in the “Info” window opened by typing “i” (Image>Show Info) with no images open. The work around for this problem is to drag Fiji.app to another folder and (optionally) to drag it back.

Indeed moving the .app out of Applications and back in seems to have fixed
it. Thanks for your help.

Hi,

I stumbled about the same problem. Using a terminal I could manually start
fiji by Using

/Applications/Fiji.app/Contents/MacOS/ImageJ-macosx

it complained about a Version 1.8 Java not being available but it started
anyway.

out of curiosity I started

/Applications/Fiji.app/Contents/MacOS/ImageJ-tiger

which fired the above error message about a Java6 needing to be installed.

Looking into Info.plist I found that the first key CFBundleExecutable was
set to ImageJ-tiger

    <key>CFBundleExecutable</key>
    <string>ImageJ-tiger</string>

using the good old vi, I changed ImageJ-tiger to ImageJ-macosx in Info.plist
and - after moving the Fiji App once out of Applications and back in - Fiji
started. This might be a workaround for Mojave…

Cheers
Stefan

My Info.plist for Fiji.App on Mojave looks different. I do not have the
problems reported here. I am attaching a PNG file of the Info.plist in
XCode to help document the differences. My application was updated last
night...

Hope this help,
John

Hi Stefan, John, everyone,

Thanks very much Stefan for noticing the Info.plist discrepancy!

John, the reason your Info.plist is different is because the version
shipped via the update site indeed has ImageJ-macosx (a working launcher)
rather than ImageJ-tiger (the one causing the "legacy Java 6" error). So if
you manage to update your Fiji, it will no longer suffer from this issue.
But a freshly downloaded Fiji will—as of this writing—reference the wrong
launcher, and therefore not be able to be started, and therefore not be
able to be updated.

Please use the forum for any additional conversation and to track progress
on the fix:

Regards,
Curtis
