I have a late 2015 model.
Processor: 2.8 GHz Quad-Core Intel Core i5
Memory: 8 GB 1867 MHz DDR3
Graphics: Intel Iris Pro Graphics 6200 1536 MB
To give an example of some frustration:
The time it takes to log out of my account, log in to my child's account, and to start something like Minecraft takes 15 minutes. This seems to be an incredibly long time to do this, does it not?
