You have:
LimeChat - http://limechat.net/mac/
Textual - https://www.codeux.com/textual/
Colloquy - https://colloquy.app/
If you use the terminal command line you have irssi, weechat, and maybe a few others. I don't know since I don't use mac.
> everyone just downloads from websites
A popular chatting application that I use (Textual IRC) recently moved focus away from Mac App Store and back to their website. It would appear that Apple takes 10 years to approve updates/new versions, and a website takes 10 seconds to upload.
As you're a fan of Limechat, have you tried Textual 5? Since Limechat is no longer under development, an awesome developer forked it, and made tons of improvements. It's not free, but it absolutely is worth the minimal cost.
My favorite is textual; you can try it free for 30 days: https://www.codeux.com/textual/
Otherwise if I was going for free ones I would look at limechat (app store) or irssi if I wanted a command line one.
I use Textual on OS X and Mobile Colloquy on iOS. Both of them work pretty nicely.
On other platforms you can use IRCCloud.
Textual. I think it's $5, but it's free if you grab it off github and compile it yourself using xcode.

I've used a bunch and this seems to be the cleanest, best functioning one for my needs.
True enough, especially for complex libraries. But for something that's more of a standalone product, I like the GPL as a user, since it guarantees that—somewhere down the line—software I like won't be abandoned, with the the most active fork being commercialized and closed source.
While I'm not going around running a 100% FOSS system or anything extreme like that (so far, anyway...I'm mostly on OS X for the time being), I have made a conscious decision to favor software that does have the guarantee that that GPL provides to the end user.
Text editors are the big category I'm working on a little at the time, slowly trying to become more and more proficient at vim (which I use over ssh a lot, anyway) to eventually replace my use of Sublime Text. Given the investment one has in a text editor, it makes sense to choose one that's not going to have a high risk of vanishing one day. (Sadly, there isn't a Free IRC client I like nearly as much as Textual. Which is a very strange one, since it's completely commercial...but it's technically a fork of Limechat from when it was BSD licensed. And they put the source for the app online, allowing you to build it but asking you not to distribute builds.)
PSA: Textual has a 30-day trial license if you just have to kick the tires before plunking down your US$5.99.
Thanks to /u/macontrack and /u/pfg1 for pointing it out. I'd been using Colloquy for the last 5-6 years. I suspect it'll no longer be on my system in a month's time. 😀

The UX of IRC depends on what client you use. I use Textual on OS X and Mobile Colloquy on iOS. Both of them work pretty nicely.
>Seriously, has anyone, ever, in the history of IRC, successfully transferred a file?
There was problems back in the day before UPnP/IGD existed but with modern clients DCC SEND should work out of the box without any configuration.
I'd love to contribute to narwhal, so I too would love to see it go open source (not necessarily free, but open source).
I understand this would be a huge decision and I would not expect the devs to do it, but oh well.
There is some precedent for paid open source apps on iOS and OSX. Textual, for example, is an IRC client for OSX available on GitHub under a quite permissive (basically you have to give attribution if you use parts of the source) license. And I am sure there are more paid and open source apps.
So this might be a possibility, but like I said, this is a big decision and I don't expect this will happen.
