@omar,
I've been surprised and annoyed by how many very specific macOS/Linux differences I encounter when doing low-level-ish C or C-adjacent programming -- stuff like, macOS doesn't have `execvpe` so you have to make a shim to launch a subprocess in a thread-safe way, or macOS forces you to always do graphics and stuff on the main thread because it has the Mach connection or whatever, or macOS doesn't have `gettid` so you need a different way to identify a thread…

@omar,
the macOS C compiler had some bizarre error with dsymutil so I had to spend like 2 hours tracking it down and then split my compile command (which worked fine with gcc on Linux) into separate compile and link stages to make it work on macOS

@omar,
making this stuff work on macOS always feels like a distraction by nature -- because I tend to already have it working on Linux, so at a gut level I feel like I'm going backward instead of doing new things, + the reason to port to macOS is really my own convenience (wanting to be able to test on my laptop instead of being tied to a PC or a VM)
