I purchased a keyboard replacement from ifixit… and most entries of the keys seem to lag, as if the mac is taking a moment to interpret the input the device and the V key may not input at all. tips? sugvgvestions? <——this is litverally what happened when i typed “sugvgvestions.”…it enters the v and G at the same time. MacBook Pro 15" Unibody (Mid 2009-Mid 2012) Keyboard Updated: After continuing to mess with the keys… it seems as though the area between the v F and G are all inputting a V. what i mean is the bottom left of G activates V, the bottom right of F actiated v, and the top of V and center activate V as well. So the area directly in the middle. Now, the shift and e keys still do “several inputs”
