[Update]: Amnesia: Rebirth's new Adventure Mode replaces otherworldly horror with puzzles.

Over the past few years Apple has made it increasingly more challenging to port games over to macOS. Even long-standing series that once had simultaneous launches across all three PC platforms started having trouble with their macOS versions, with the end result usually being lengthy delays or outright cancellations. Unfortunately, due to insurmountable technical problems, Amnesia: Rebirth and SOMA have now been forced to go with the rather unappealing second option.

"We’ve always prided ourselves with being able to supply our games on PC, Linux and Mac, but we have now encountered some serious problems with the latest versions of MacOS," reads the brief update. "Even though we’ve put in tons of effort trying to fix the issues – so that SOMA and Rebirth supports MacOS – we have finally had to give up. We simply cannot manage it."

As for where exactly the problems lie, well, it's a bit of a mess as you'll quickly see.

"OpenGL was deprecated in macOS 10.14 (Mojave). Newer macOS can still run OpenGL games but there are no tools to help development," continues the update. "If a graphics related bug occurs we are blind and have to guess what’s going on, which increases the workload per bug to extreme levels."

"Changes to the audio drivers in macOS 11.0 (Big Sur) has caused our sound engine to stop working. We have been in discussion with our third party partner and they have no plans on updating the sound engine to support the latest macOS. This means we would have to change to a different sound engine, meaning a complete reimplementation of all sound effects without even knowing that we could reach the same quality."

What this means in the end is that the upcoming macOS version of Amnesia: Rebirth has now been officially canceled, while SOMA won't fully function on the latest version of macOS. You can still technically play it, but you won't have any actual sound, which sadly makes the whole exercise a bit pointless.

Should anything change I'll make sure to let you know. Until then, you can read a little bit more about the macOS versions over at the Frictional Games website.
