I purchased this refurbished MacBook with high expectations, but unfortunately discovered that the left speaker is completely non-functional. While the rest of the laptop appears to be in decent condition, this audio issue significantly impacts my user experience, especially for video calls and media consumption. I'm particularly disappointed as this wasn't mentioned in the product description. I've had to invest in external speakers to compensate, which wasn't part of my budget. This experience has made me more cautious about buying refurbished electronics in the future.
