M1 requires Apple 'notorization' and I don't have an Apple certificate to sign my builds (the unsigned M1 versions will refuse to run..) The Xcode project file included in the source supports targeting M1, so you can build yourself (or keep using the x64 version.) 

While I don't know much about M1 compilations, I believe there's a way to build native apps for Mac Silicon without the pesky Apple notarization. I may be wrong, though.

Anyway, multi-thanks a lot for keeping Quake alive on Macs!

If there is, I'd like to know.

You're most welcome. 

Version 0.96.1 of QuakeSpasm is released.

Downloads:

Changes since the previous version:

- Fix demo recording as client-only after connection to server (was
broken by signon changes in 0.96.0. Thanks to Jozsef Szalontai for
issue report.)

- Fix potential buffer overflow in COM_Parse(), e.g. with maps with
oversized 'wad' fields. (Thanks to Andrei Drexler.)

- Minor code cleanups. 

since v.0.96 is able to complete Mjolnir for now. May be it is time to update IronWail wich unable to run this mod normally? (map mj4m4 IW won`t load at any way for me). BTW IW my common Quake engine for now. I make no claims, I appreciate work of mr. Andrei Drexler. Thank You.
