Hi all,
I have a weird problem that I believe involves how Java is installed/setup on one of my Mac laptops running MacOS 10.12 (Sierra). I installed JRE 8 from Oracle for running Fiji. Fiji runs fine. I can also run ImageJ, and it tells me I’m running JVM 1.6.0_65 (the legacy Apple JVM). When I try to launch Micr-Manager 1.4 or 2.0beta, I get a brief flash and then neither launches. If I use Apple Jar Launcher to launch the ij.jar file then both MM 1.4 and 2.0beta launch, and they show I”m running JVM 1.8. I tried redownloading fresh apps from the Micro-Manager web site, with no effect.

I have another laptop on which Micro-Manager 1.4 and 2.0 beta are installed in which (I think) I did the same Java install involving JVM 1.8. They launch flawlessly and are running JVM 1.6.0_35. This all suggests some environment variable or something is weird on the other laptop. However, the fact that ImageJ runs fine has me baffled.

Can anyone provide some advice? I mainly want to open Micro-Manager datasets on the laptops; we use Windows machines to control hardware.

Thanks in advance for your help!
Cheers,
Jeff
