Yes, you can safely play on your MacBook.
You can continue playing on a MacBook even though it wasn’t built for it. League of Legend works, just keep the environment nice and cool—try adjusting the temperature or using a cooling pad. Gaming on a laptop often raises temperatures, so maintaining a comfortable heat level is important.
MacBooks aren't built for gaming purposes. They can function, but they won't operate efficiently without proper heat management.
It makes sense that things get warm—otherwise it would suggest the cooling system isn't working. Generally, running high-power activities on a thin laptop for extended periods isn't ideal, even if it seems possible in theory. The prolonged heat could eventually strip solder joints or harm the internal components, leading to failures or even hardware damage over time. So, the short answer is yes, it's relatively safe, but trying to prevent it is better.
I suggest waiting until you've refreshed the thermal paste and completed the Windows bootup process before trying it. Once that's done, run the app named MacFanControl. Otherwise, you risk damaging your GPU—just as Apple planned it to handle high temperatures before setting the fan to maximum.
