Just download it and add it to your bag of tricks.

I'm an old hand at macs and I've known for years, that there's a lot of magic in this stuff.

Don't let'em fool ya!

You would think Stuffit would work to unrar, expand, un-Stuff everything?

Nope.

Or Rar Expander?

Or The Unarchiver?

Yup.

They all work.

None of them work.

Get them all.

For some reason, some files will only open with one of these prog's.

I dunno. I've given up.

Old enough hand, like I said, to know it's magic.

UnrarX opened a rar file that none of above would open.

Kudos to it.

Get it.

Amazingly, if you search MacUpdate.com for "Rar," UnrarX does NOT come up!

Since unRarX hasn't been updated in quite a while it still includes some fairly outdated versions of unrar and par2. Here's how you can manually update the binaries yourself:

RAR
Download the newest version of RAR (http://www.macupdate.com/app/mac/11159/rar), extract it, and look for a binary file simply called "unrar". Now locate UnRarX.app in the finder, right-click it, and choose "Show Package Contents" from the contextual menu. From here navigate to the folder /Contents/Resources/, and copy your new version of unrar here, thereby replacing the old one.

Par2
To get a more recent version of par2 you may need to download an application which already contains a compiled binary. I recommend going with MacPAR deLuxe (http://www.macupdate.com/app/mac/11858/macpar-deluxe). Download it, mount the DMG, and open the package contents as described above. Again, navigate to /Contents/Resources/ where you will find a binary file called par2SL. Copy it to the same directory in your UnRarX bundle, delete the old par2 binary and rename the new one to par2

If necessary, relaunch UnRarX. That it, you're set.

There are better tools than this (MacParDeluxe, for instance, which is also free and coded to take advantage of 64-bit and multiple cores), but I still keep UnRarX around since its console-y implementation gives me immediate feedback on which .rar piece is problematic. Other tools simply report an error (or require digging through logs to identify the bad bit).

Still the best unrar available for OS X. Period !

I love this old app, but it has a major problem, and I don't know if it's just because I'm running it on a modern Intel system using OS 10.5.8 when it was probably designed on a Lisa-II (it's nearly that old).

The problem is that unchecking the preference to "Overwrite existing files" does not stick (meaning it's not persistent after the app has been shut down), so it always starts up with that pref checked, and that means that I can't just double-click on a .rar file to start the extraction if I don't want to overwrite the original archives (which I never do). So, I always have to open up unRarX 2.2 first and uncheck that pref before selecting the file(s) to extract, adding a step that most such apps long ago made erroneous when they added double-click-the-archive-to-start functionality.

It's not that big a deal, but it is just the kind of annoyance that will make me turn my head when some other cheap, nubile young unarchiver comes on the market.

Is this a bug? i set extraction destination to Desktop, but the extraction always change back to File Directory when starting to extract...
