On macOS Tahoe (26.x, tested on 26.3 / M3 MacBook Air), system audio gradually degrades over time — volume drops significantly and sound becomes muffled across all outputs (built-in speakers, Bluetooth headphones, etc.) at the same volume setting.
coreaudiod sometimes shows elevated CPU usage during the degraded state.

A JSON compilation database is a very handy output format which is parsed and used by many development tools. Unfortunately for us Apple Developers, it is not straightforward to generate one from within Xcode, as it is (probably) not Apple's priority and therefore there is no toggle/switch/setting that can be easily enabled to get this information.
There is however a solution, thanks to Apple using Clang/LLVM as their main toolchain.
The standard way to generate this with clang would be to use the -MJ flag and give it a file name that typically corresponds to the input file. Using this flag indirectly through Xcode is hard, given that we're not aware of all the other arguments when a compiler call is executed.
However, there is a second hidden/badly documented LLVM flag: -gen-cdb-fragment-path - it is implemented in terms of -MJ and has the same functionality, but it's argument in contrast is an output directory.
| // Adds the ALT_TAB keycode to a QMK keymap. | |
| // Based on https://www.reddit.com/r/MechanicalKeyboards/comments/mrnxrj/better_super_alttab/ | |
| // Functionality is the following (basically the same thing as a normal Alt + Tab but without having | |
| // to leave Alt pressed): | |
| // - On pressing ALT_TAB, the window switch menu pops up. | |
| // - While the menu is visible, it's possible to cycle through the selection by pressing ALT_TAB | |
| // again, or Shift + ALT_TAB, or the arrow keys. | |
| // - The selected window can be brought up by pressing Enter, which also closes the menu. |
| /* In your config.h define a new variable RGBLIGHT_TIMEOUT and give it a value in milliseconds */ | |
| #define RGBLIGHT_SLEEP // allows us to use rgblight_suspend() and rgblight_wakeup() in keymap.c | |
| #define RGBLIGHT_TIMEOUT 30000 // 30 seconds |
