I no longer have access to the Mac machine I've been using to build Mac binaries of xCHM on.
Sadly, that means that I will no longer be able to build any new versions of xCHM for Mac OS X. The remedy, unless this is to happen again, is to get a dedicated Mac machine. Unfortunately, the cheapest one available to me costs 800 EUROs.
If Mac binaries are important to you, and you can't or don't feel like building your own from source, please use the "Support this project" button on the bottom of any page on the website, and maybe we can build up to the required sum.
Please be warned that it is possible that I won't be able to raise the whole sum, and I don't think I can return the donations in case the final goal cannot be reached.
Thanks for reading!
