Summarizing what was done here and the factors governing WebGPU enablement on MacOS:

* The default for the `dom.webgpu.enabled` preference in [StaticPrefList](https://searchfox.org/firefox-main/source/modules/libpref/init/StaticPrefList.yaml#5552) was changed from false to true when `defined(XP_MACOSX) && defined(MOZ_AARCH64)` (i.e. MacOS running on Apple Silicon).
* [The graphics feature blocklist](https://searchfox.org/firefox-main/source/widget/cocoa/GfxInfo.mm#518) blocks WebGPU with `FEATURE_FAILURE_WEBGPU_MACOS_26_REQUIRED` if MacOS is not Tahoe or newer.

Both of these changes only affect late beta or release builds. Nightly or early beta were already setting `dom.webgpu.enabled` to true, and the feature block is conditioned by `#ifndef EARLY_BETA_OR_EARLIER`.

In Firefox 143.0.3 and 144, it is possible to enable WebGPU on any MacOS version by setting the `dom.webgpu.enabled` preference (see bug 1987533). In Firefox 145, it will be necessary to set `gfx.webgpu.ignore-blocklist` to enable WebGPU on pre-Tahoe MacOS.

Bug 1993341 tracks removing the blocklist entry and enabling WebGPU on additional MacOS versions.
