I was curious if anyone out there is running Mojave Beta on a 2015 mbp 13", and if so how is it going? I am completely new to Mac computers and mac OS and I am looking to buy my friends 2015 mbp 13" ( 400 battery cycles, serial numbers line up, etc.) to better familiarize myself with a different OS. He's offering it to me for $700 which is a very competitive price and im comfortable with the condition of the device. My biggest concern right now is how well an older model takes to the newer OS. Please let me know if you've felt that mojave beta hasn't been running optimally!
