Based on my own experience, there's been no significant issues after I updated my MacBook. Although, mine is an Air but it should be the same.


Before updating, remember:

🔋Check your Mac has enough battery (if not, charge when you could or the update will pause until it is)

📁 Make sure your files are all saved, or they might lose data

💡Best to quit any tabs to ensure the productiveness of the update


Good luck! 🍀
