i thought it died years ago, but apparently the battery was just so low that it wouldn't even try to charge. briefly injected 5 v to the battery terminals and now it's working and charging off usb!!
sadly the pokemon save is long gone since they need power to keep data..
ofc, i'll be keeping the 11" macbook air as my main laptop since the 12" is very slow and a notoriously unreliable model, but it _is_ very light and very cute..
bought as non-working on ebay for ~100 cad. turned out all internal flex cables were torn (???), the keyboard had several bad keys, plus an unrelated short in the touchpad caused it to intermittently think the power button was held down 😅
...at least the main board and screen were alright, and i stole cables and a keyboard (~90 screws, yay) from a second machine. the touchpad issue confused me for a while but resolved in the end just by cleaning corrosion!
for the macos 26 beta enjoyers, this seems to enable a water animation on the default wallpaper (at a couple fps, lol, maybe hidden for a reason)
sudo mkdir -p /Library/Preferences/FeatureFlags/Domain
sudo defaults write /Library/Preferences/FeatureFlags/Domain/NeptuneWallpaper.plist onemove -dict Enabled -bool true
also didn't realize these things' fans are fully off most of the time, afaik the airs are always spinning at low rpm? kind of neat
