JILL PAT  Still the best unrar available for OS X. Period !  
(Version 2.2)

FORMICA  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.

JILL PAT  Old but still the best unrar util for osx.

Simple

Fast

Does the business

And free

MRPHANTOM  Another happy ending. My standard rar expander program on mac was not doing the trick so I tried with unrarX... done deal. Two thumps up.

ROBOTANK  Very nice. Today I suddenly ended up with a rar that Path Finder's built in Stuffit engine wouldn't handle properly (the first time that's ever happened). unRarX expanded it no problem.

ALBABE  unRar opened .rar files that Stuffit kept reporting errors on.

The "Password" box took me a few seconds to find. Be aware.

Great Ap!

FRINGEWOOD  Very handy in most RAR cases.

Needs a password dialog.

It would be handy when the archive contained multiple files, to create a folder to contain it all, rather than let it flood the current folder. It's a hassle to create a new folder and drag the archive into it every time to be safe.

APPLECRYPT MODS  sry but I find this app often unreliable at times with large rar/split archives. It reports CRC errors, but I use the freeware tool Stuffit Expander and this works perfectly. Then again, UnRARx hasn't been updated in a long while... ?

TOROSROSS  Great lil' proggie. I love it.

My only suggestion is to make this option available:

IF "All OK" THEN QUIT unRarX :)

Cheers!

MIKURO  This is probably the best rar expander for Mac. It has successfully expanded split rars that The Unarchiver could not handle. While the interface is not the best, it's easy enough, and it gets the job done.

The Unarchiver is still my primary archive expander, since it handles just about every format and works well 99% of the time. But when it comes to troublesome rars, unRarX is excellent.
