Tried Halloy on macOS for ~6mos, has some serious issues ...
(1) It silently disconnects from the server without indication, and does not reconnect. You might assume it is connected, until you send a message and see "message can not be sent". You will lose conversation history unless using a bouncer. Clicking around, all the buffers will clear indicating some major state issue, and you will have to restart it.
(2) Consistently uses ~5% CPU doing nothing at all.
(3) Doesn't behave like a macOS app, pressing the red "close window" button will close the window, but the main process goes ANR.
After leaving Textual since that was discontinued, guess I'm looking for a macOS IRC client again. Might give Mango a try.
Yeah, Halloy is "interesting", although I haven't personally run into issues yet. It just clearly not a native Mac app, which is fine, but not my ideal.
But Textual! I just stumbled across this yesterday: https://www.textualapp.com/news/a-new-chapter
TL;DR someone bought Textual and are restarting development. It's not a PE-style purchase, like a Bending Spoons / Evernote kind of thing. According to the buyers, they bought it because they're heavy users and wanted to take it over so they could resume active development. I always keep a healthy skepticism, but I'm hopeful.
