    Today I downloaded Jin which is a program for chess. Upon installation I was told that "Rosetta" needed to be installed.

    1- What exactly is Rosetta?
    2- Will Installing it slow down my Laptop?
    3- Is it a good idea to install it?

    Thanks

    1) It's the PPC emulation layer that shipped with the earlier versions of OS X.

    2) Probably not, but it's not typically something you "install" - it's normally already installed...

    3) No. In this case, there's either something seriously wrong with your system or the Jin package you downloaded is incorrect in some way (either just very old or possibly compromised). According to it's website, Jin is a Java-powered app - it shouldn't care *what* architecture it's running on, as long as the JVM is correctly installed.

    I think Jin Chess uses JNI libraries...which means it won't operate under Rosetta.

    edit: hmmmm...just downloaded jin & it runs fine on my 2010 MBP.

    Unless you're running any PowerPC applications, you won't notice any slowdowns. If you are running PowerPC apps, consider upgrading the app (if possible).

    Otherwise you shouldn't notice any difference in your day-to-day use.

    Well, I have a brand new 13" MBP(2010), just got it 3 days ago.
    So should I try to re-download Jin?
    Just go ahead and install Rosetta?

    I have the same computer, 13" MBP, which is less than a week old. I had no idea what Rosetta is but it came up when I did something, don't remember what, and a window popped up asking me to download Rosetta. I downloaded it but still not sure what this is all about but there are no noticeable performance difference.

    In Snow Leopard, Rosetta is no longer included in the default installation. It will prompt to install itself the first time you try to launch a PowerPC application. Having it installed will not affect performance, although leaving PowerPC applications running in the background may affect overall system performance.

    Rosetta weighs only two megabytes. So the hard drive space is not an issue.

    It is only used when a PPC app is opened. So you can install it and forget it. If you have to run a PPC app, it won't be that slow anyways, as these apps were made to run on much slower computers.

    Correct. It’s to enable you to run those older PPC-only apps on an Intel system.

    No longer true in Snow Leopard, which a new machine would have. Yes, it’s safe to install, and no it won’t slow down the computer. EDIT: No, it won’t slow down the computer overall. The apps running in Rosetta will run slower than if they were universal apps, but on the newest systems, probably faster than they ever ran on a PPC machine anyways.

    Ok, I trusted you guys on this one and installed Rosetta, now I can run Jin. I shouldn't expect any slow downs.

    Wow. We sure have come a LONG way since the Intel Switch when every 5 minutes, the word "Rosetta" was mentioned in the forum. Now we have people who have no clue what it is.

    Quite amazing, really. :)

    So Rosetta should ONLY load if I use Jin right?, otherwise, my MBP is the same as before I installed it ,right?

    No.

    It's like a cooker. Installing it into your home won't make you use more electricity. You only use the cooker when you need to cook, then you use electricity. After you have finished cooking, you turn it off, and it doesn't use more electricity.

    Same thing.

    I ended up uninstalling Jin. It seems that running Rosetta/Jin leached my battery all the way to 18% in 30-45 minutes! good thing I noticed just in time.

    Well it wasn't Rosetta's fault!

    Yes, must have been JIN or something completely different.
