MLBKXBX  I like. When i used linux i couldn't find any chm viewer worthy of actually using. So i simply didn't read chm files. There are some excellent chm's out there though so you really want a good chm viewer (php manual comes to mind). Ichm has got everything i need.

Looks, search feature, bookmarks, tabs, stability. It can only get better from here!  
(Version 1.4.2)

HERLITZ  Does everything it's supposed to. All + here!  
(Version 1.4.1)

SURFSPIRIT  Fast and the following feature is a must for me "Save whole file to PDF"

Great App! :)  
(Version 1.4)

RICHOZ  Simple and to the point. Great app!  
(Version 1.3.2)

TERRYANDTAOTAO  Among iChm, xCHM chmox and ArCHMock, iCHM is the the only one I would recommend.

I know it only took the coder several days to finish it. Really appreciate it. It's good to see more Chinese developers write high quality opensource programs.

TEKL  I tried several CHM Viewers for OS X. iChm, xCHM and ArCHMock are the only one which I can recommend.

But all are not perfect yet.

ArCHMock 1.1:

+ Fast

+ Nice Interface

+ Good HTML rendering (Webkit)

+ Highlighting search results in Text

+ Good keyboard support (Cmd+G etc.)

+ Bookmarks

+ Automatically locates the current page in the table of contents

+ Good search results (can be sorted by relevance)

+ Zooming can be resetted

+ Remembers the last position

+ Open source

- No Index

- No options for searching

- No "find in page"

- No toolbar button for print (but Cmd+P works)

- No tabs or multiple document windows

iChm 0.9.1:

+ Fast

+ Nice Interface

+ Good HTML rendering (Webkit)

+ Tabs

+ Auto-update feature

- No Index

- Bad keyboard support (no Cmd+G)

- No options for searching

- You habe to manually 'locate' the current page in the table of contents

- Only searchs for words (no partial search)

- No home button (and no hotkey for that)

- Because of the small tabs its hard to get the title of the current page (which is not shown in the window title)

xCHM 1.13:

+ Contents/Index/Results on left side

+ Searchable index

+ Options for searching in titles only or partial

+ Automatically locates the current page in the table of contents

+ Bookmarks

+ Open source

- Ugly interface

- Bad HTML rendering

- Does not support custom context menus (like in SelfHTML)

- Slow (scrolling)

- Search results are always sorted alphabetically

- No tabs or multiple document windows

- The binary of the Mac version won't be updated anymore

At the moment ArCHMock has the best usability for me.  
(Version 0.9.1)

GAOSHAN  Now that I have had a chance to use a working version, new review.

I like it. The cocoa interface is better than much of what is available in other chm viewers. Tabs are nice to have as well.

What does the "Locate" button do? Clicking it doesn't seem to do anything.  
(Version 0.9.1)

GBK  OK ! now all is good on MU ! really reactive :]  
(Version 0.9.1)

GBK  ok, i've missed sthg : "Intel only"...  
(Version 0.9.1)

SCOTTDB  Perfect CHM reader.

Cocoa, tabs, fast, simple interface, SEARCH!

Well done. I'll be donating shortly.
