Same app, different binaries, peaceful coexistance!

[Mechcozmo]

I downloaded the new "Temperature Monitor" app. I had 2.5, the new is 3.2. Anyway, I quit the old one, dragged the new one from the disk image to my Applications folder... and.... it copied! No prompting to overwrite!



Turns out, one is a Universal Binary and the other one is PowerPC only. I guess they can exist peacefully. Thought it was interesting.

Being a Universal Binary has nothing to do with it. The two apps have different names. There is probably an extra space in the name of one of the apps.

I am thinking the same thing. I have NeoOffice/J on my iMac at home. I recently downloaded the 1.2 Beta version and ASSUMED it would overwrite the other version. It didnt!! Why? 1.2 Beta is listed as NeoOffice, not NeoOffice/J as the previous version did. THerefore, they existed side by side. I had to manually delete the older version.

Er... no.
Look at the screen shot. It is nicely spelled out for you there; they are the same. It IS the universal binary thing.

That'd be different names. Different names=co-existance. Same names=issues.

So you can see leading or trailing spaces in a screenshot?

That's certainly possible, but why would the authors do that?

I can see the leading ones for sure (though there isn't one in the screen shot).

Nope, the author changed the application names.

Version 2.5 of Temperature Monitor (the one I currently have installed) is actually named Temperature Monitor.app. (Finder hides the .app extension and the fact that Temperature Monitor.app is actually a folder.)

Version 3.2 of Temperature Monitor (that I just downloaded) is actually named TemperatureMonitor.app. I presume that Finder is picking up the name "Temperature Monitor" to display by reading some meta-data out of the application.

Edit: Finder displays the name stored in the Resource fork of the application as the application name in the finder view. This is the location of the meta-data I mentioned above.

Ahhhh.... interesting. Thanks for clearing that up. I thought that since they were different styles of compilation, they were stored differently. I guess I was wrong. Thanks again for finding the different names.

And no gloating MisterMe, because you didn't know how you were right either!

Mrichmon, thank you for the explanation and education!
