I'm thinking of upgrading sometime in the future to a 16" MacBook Pro. As someone who keeps my Mac with me on the go, I'm very cautious and alert, but still want to plan for the possibility that it might get taken.
I'm wondering if there's enough room somewhere under the bottom cover to fit one of those ultra slim Tile tags. It would go completely undetected long enough for the laptop to be tracked down, even if Find My Mac wasn't able to phone home.
As janky as it sounds, any smart thief would sit and try around T2 and macOS to disable things, or avoid connecting to the internet. But a random Tile stuck inside the battery compartment is the last thing most of them will think to look for, especially if it blends in with things.
