Available for Windows, macOS and inferior "systems", SoftMaker has already released their first Office 2021 beta version into the wild. I'm currently trying it on macOS and it seems to work just fine. Currently, a paid license enables me to install it on "up to five computers", so my two Windowses and my one MacBook would be covered. The only thing that prevents me from instantly buying it is that SoftMaker has already started to introduce features which are only available in the subscription version "Office NX" and I hate subscriptions...

Mine isn’t here yet.

Personally, I dislike the zsh (it does too many things), but I am currently spending some time with a Mac and they come with the zsh these days. Trying to make it relatively useful is annoying.
