> Apple just doesn't seem to care about build quality beyond the cosmetics of their Mac lineup. A great example of this is how they have dual connections from the keyboard & trackpad to the mainboard (USB and SPI), while the UEFI and Linux have drivers to support the keyboard fully, macOS has no driver for the built-in USB connection. Well, it's complicated. In the past mobile Macs used USB to connect the input devices like most other notebooks do. At a certain point Apple decided that it would be a good idea to switch to SPI for power consumption reasons. Following that decision there were certain models which had wired both, e.g. the MacBook Pro 2015. While Apple switched already to use SPI there, Linux still used USB, as there was simply no driver support. The Retina MacBook in 2015 was the first mobile Mac which didn't support USB for input devices anymore. The MacBook Pro followed in late 2016. That left Linux without a working driver for the input devices. A year ago somebody started to reverse engineer the SPI protocol to get a working driver: https://github.com/cb22/macbook12-spi-driver/ https://github.com/cb22/macbook12-spi-driver/ The release of the SPI-only MacBook Pros end of last year sparked the further development of this driver, so it's slowly reaching a state were everything is just working (maybe except for advanced Touchpad features). That driver is still not included in any major Linux distribution, as it's still pretty experimental and also required patching the Linux kernel for quite some time, because Apple does some ACPI-related stuff different than the PC-world. Thankfully support for Apples way will land in the upcoming Linux 4.14 (https://github.com/torvalds/linux/commit/53ac64aac9af8cd0e5456c8a9bb68c47b571b0a9 https://github.com/torvalds/linux/commit/53ac64aac9af8cd0e54...) making some code in the driver redundant (https://github.com/cb22/macbook12-spi-driver/pull/46 https://github.com/cb22/macbook12-spi-driver/pull/46). So I would say that whole topic isn't about not to care about build quality, but about to care about power consumption. Still having USB on some generations of Macs in addition to SPI was probably simply to ease the migration by unbundling the hardware changes from the software changes.
