Answer to: How to remove pentalobe screws without correct screwdriver?A flat blade screw driver that fits between any two of the 5 "lobes" may work or between one out-pointing lobe and an opposite in-pointing lobe... unless they're in there too tight. The right tool (pentalobe screwdriver) is really the right choice. It puts the force basically equally on the right places of the 5 edges. I tried a tri-lobe (security bit area) from Menards for the tri-lobe screw for the trackpad and it was too pointed to fit. A flatter tri-lobe is needed. I might have to spend the $$ and get the right sized tools as I plan on having to do some repairs. Then again, the tri-lobe from menards was only $2 so I might just try grinding down the tip with my Dremel. For the trackpad screw, a small flat blade did work from one outer lobe to the left or right of the opposite inner lobe (depending if loosening or tightening), but it wouldn't work on the smaller tri-lobed screws on the keyboard side of the trackpad as they were just too small for the blade.
