When life serves you lemons, you make lemonade.
When life serves you a bad Apple, you break out the big tools.
My 2009 Macbook Pro had a dying battery, so I had a replacement battery and special tri-wing screw driver tool shipped ahead to Austin. The easy replacement turned out not to be so easy.
After the replacement or upgrade of various components (screen, hard drive, and memory) at different times in the past four years, I managed to strip out a screw on the bottom plate of the Mac.
After the gentle touch failed, it was time to break out the power tools to the horror of any purist or Mac geek.
An attempt to drill out the offending screw with a left handed bit failed, there was nothing to do except go medieval.
A few broken drill bits and a hole a little smaller than a pen diameter later, the back cover still would not give. Force and some snapped aluminum bits later, the Mac had a new battery. Ugly but functional.
My Apple now has a worm hole, which is better than biting an apple and finding half a worm.
