A:AnswerNo, you received it with an English keyboard. You can add the Spanish keyboard layout in the settings, and special characters like ñ and ´ will display.
A:AnswerYou can mirror your iPhone by connecting your iPhone to your MacBook. Open QuickTime -> New Moving Recording -> Select iPhone as the Camera. You can also use the App called Reflector.
A:AnswerNo, I do not think that specific configuration is available. Although I have never seen a computer boasting 25gb of RAM before either haha.
You can spec a new model out directly for Apple with up to 24gb of RAM I believe. If you are wanting that much RAM though, it is probably best to consider MacBook Pro options since they tend to be more focused on performance and can be configured with way more RAM. You will just pay a pretty penny for it unfortunately.
As far as the 25gb configuration specifically, please keep us updated if you find a model that offers that lol
A:AnswerMine came with MacOS Sequoia. The system indicated that it was up to date, but once an update is available you would be able to download it on your laptop and update it immediately.
