Hi,I am overall impressed by the quality and condition of this renewed laptop.Pros- Condition is really good. Very little physical damage such as dents and scratches- Screen is beautiful, bright and a joy to look at. So glad I went with retina.- The performance is snappy. I use mine for software and mobile application development and it is holding it's own very well.Cons- I got a German Keyboard. I wasn't looking, but I did not see anything about the keyboard so I just assumed. Kinda difficult getting used to it.- The battery life is very short (about 3 hours). I expected as much as the laptop is about 7 years old. I will eventually replace to get better battery life: this is easy to do with this laptop.- I am unable to upgrade to Catalina OS even though the update is available. The disk is in the wrong format and I cannot convert.UPDATE: 2022-11-11I did manage to upgrade to Catalina OS with some disk formatting.
