hid-magicmouse treats a resting thumb as a second finger, so a light edge contact becomes two-finger scroll or a right-click. Stock libinput also disables size-based palm/thumb filtering on these pads (TouchSizeRange 20:10). Skip kernel gesture emulation when a Magic Trackpad is present, re-enable libinput thumb/palm thresholds, and keep Hyprland's default sensitivity and adaptive accel on the pad even if the user raises the global pointer speed. The same kernel module drives Magic Mouse, whose surface-scroll still needs emulate_scroll_wheel, so those options are skipped when a Magic Mouse is connected.

On Linux, a Magic Trackpad treats a light resting thumb as a second finger. That becomes two-finger scroll or a right-click, and small pointer moves feel jumpy compared with macOS.
Two layers cause it:
hid-magicmousekernel two-finger scroll and 3-button emulation fire as soon as a second contact exists, before libinput can classify it as a thumb.50-system-apple.quirkssetsAttrTouchSizeRange=20:10on these pads, which turns size-based palm/thumb filtering off.This change:
/etc/libinput/omarchy-magic-trackpad.quirksso a light edge rest is ignored. Harmless on machines without the pad (match is by device name)./etc/modprobe.d/omarchy-magic-trackpad.conf(emulate_scroll_wheel=0,emulate_3button=0) when a Magic Trackpad is present, so libinput owns two-finger scroll and click. Two-finger right-click still works throughclickfinger_behavior.0on the common Magic Trackpad device names, so raising the global pointer speed does not make this large pad jumpy.Tested on a USB Magic Trackpad 2 (05AC:0265) on Omarchy 4.0.1. Resting-thumb scroll/right-click stopped, and fine text selection became usable.
