News coverage and some surprises
The release of Apple Silicon-based Macs at the end of last year generated a flurry of news coverage and
some surprises at the machine's performance. This post details some background information on the
experience of porting Firefox to run natively on these CPUs.
We'll start with some background on the Mac transition and give an overview of Firefox internals that
needed to know about the new architecture, before moving on to the concept of Universal Binaries.
We'll then explain how DRM/EME works on the new platform, talk about our experience with macOS Big Sur,
and discuss various updater problems we had to deal with. We'll conclude with the release and an
overview of various other improvements that are in the pipeline.
