Protecting MacBook keyboard

Hello, thank you for reaching out.

Yes, keyboard skins/covers are typically discouraged by Apple because it can result in damage to the screen.

In my opinion, keyboard covers aren't really necessary, and they can also affect cooling and restrict airflow. MacBook keyboards in my experience are generally pretty durable and you shouldn't have too many issues with it.

Hope this answers your question, have a great 2024!

Do not use keyboard covers on your MacBook Air. Such covers may cause damage and they may interfere with computer cooling.

Apple has no warnings about overheating.

A keyboard cover is a great idea if you remember to remove it everytime you close your laptop.

I've used a keyboard skin on my 2012 MacBook Air with no problem. Someone else in the household has been using one for about the same time. The main reason I use it is because I often eat while I'm using it and want to keep crumbs from going into keyboard.

My two data points. I now have a new M2 and will probably get one for it, unless I read a good reason not to.
