Edit: Jesus Christ, people. If you buy a $150 Thinkpad made by slave labor instead of a $1,200 MacBook made by slave labor, you're still supporting a capitalist economy based on slave labor. We all do. We have no choice. The number of smug liberals in the comments saying "well I buy a cheap used laptop" or "well I buy coffee beans and make my own coffee" are completely missing the fucking point.
Don't tell yourself your consumption is moral. All of us make unethical choices every day because there is no ethical consumption under capitalism. Accept your shame and guilt and let it drive you to do better.
Another point to her cause I haven't seen in the comments -
How old is that MacBook and how many hands has it passed through? In my experience, anybody with new (any tech really but ESPECIALLY) Apple products keeps that shiz pristine. I grab a cheap laptop off CL though I'll absolutely sticker it up.
My vote is she's in a school program or something that requires macos stuff and grabbed it second hand off someone on the cheap.
Apple products can be surprisingly cheap to win on eBay too. I never hunted macbooks, but grabbed earlier Gen Ipads for dirt cheap with good batteries. Unfortunately I learned tablets are not really that much of a convenience when you you're willing to sacrifice your eyesight out of laziness to do the same thing on your smartphone... plus the lack of apps is frustrating, but even less frustrating than the excel navigation...
Wow that's some convoluted religious type excuse.
