my hostname is not my laptop name My laptop's hostname appears to be Georges-MacBook-Pro-Mid-2145.local,



$ hostname
Georges-MacBook-Pro-Mid-2145.local


Why is the number reported here 2145 instead of 2015? (I own a MacBook Pro Mid-2015, so I was expecting the host name to be Georges-MacBook-Pro-Mid-2015.local).

Did I do something wrong somewhere while twiddling about in the terminal or is it normal that the last numbers are... "random" (?)
Have you tried clicking the edit button that's right next to the hostname that you want to edit?
