ANONYMOUS  Very clunky and useless. It would be better if you could just click on a value and start changing values. What's the point of a hex editor if you have to keep going back and forth between your cursor and a text box to edit every single value? It would take forever to change anything. Also why is the editing off by default? Isn't this a hex EDITOR?

ANONYMOUS  Shows me more than PeekIt did. Looks nice, works like others that I'm familiar with. Pretty nice.

KARINA  Not all that intuitive to use, but the price is right and it works well.

EDWARD CHEW  One thing which tripped me up was when you do Select All, it only selects one page out of the file instead of the whole file. Strange.

GARY  This program is alright, it does what it says on the can :) (although I managed to successfuly edit a file with the "allow editing" box unchecked). To the guy who wanted to open an app and get its hex code like on OS9, most OSX applications are actually folders in disguise, which contain resources, nib files, etc. To view the contents of the applications, control-click them and choose "Show Package Contents".

SIMON LOK  Although the user interface is not the most intuitive in the world (and there are some spurious messages that are simply untrue), this program does exactly what you would expect of a Hex editor. You can open a file, click on the "allow editing" button and start modifying it.

This program has a very useful multicharacter search (excellent for finding those long strings, typically needed for fixing blacklisted you-know-whats) and basically modifies a file in place. Obviously this means you need to backup your files before loading it, yet another usability issue (no warning about this in place editing business whatsoever).

NICKSAY  I'm not sure what the previous posts are about... I just used the program successfully. Admittedly, the interface isn't the most intuitive, but it's not exactly "bad" either. Perhaps the previous users need a pointer or two. 1) The app doesn't use a traditional "save" mechanism, where you edit a document in memory and then write it out to disk, usually without affecting the original. Instead, make sure the arrow at the bottom is expanded, and select the "Allow Editing" check box. Now, if you select some part of the file above, the "View/Edit as..." fields will IMMEDIATELY OVERWRITE the contents of the file upon hitting return. MAKE A BACKUP FIRST! Otherwise, you can't get the original version back. 2) Despite previous comments, you CAN move to an offset in the file. Using the "Selection" fields, set "First" to the offset you wish to start at, and "Size" to the amount of data you want selected, starting at the offset. You'll notice that selecting part of the file, or searching for a string (hex or ascii) will automatically set these fields. So, frankly, I have no problems with the app, and when I need it, it comes in handy.

ANONYMOUS  Unfortunately, this is not worth downloading. The interface has about as little comfort as you could imagine (there's not even a function to go a certain offset in the file); and saving a file that you changed fails, so it's no use.

ANONYMOUS  I was thinking it would be like how it was in OS 9... Open any app, see it all in it's raw hex form... Not the case in OS X =/
