My trusty MacBook Air 11.6" mid 2011 that has served me so well has started giving problems. Originally the SSD was nearly full and also full of trash I didn't need at which point the beachball of death started to appear. I wiped everything and did a fresh install which was problematic as the install kept freezing, but eventually got it to work and the third attempt. All seemed well until the beachball of death appeared again and again. You can't do anything now without it happening after about a minute. I am now wondering if the SSD is on the way out and if it is worth repairing? Any thoughts or observations would be very welcome.
