If you're using a Mac, then you likely have no way to unzip or open a .rar file. I ran into this issue when downloading a firmware update for my Ender 3 V2. There is software available to unzip the .rar files, but a lot of it costs money.

I found a free app for you to use!

What is a .rar file?

.Rar is short for Roshal Archive and is a data compression file similar to a ZIP file.

And here's how you can open them on a Mac!

By default, Mac computers will automatically save the screenshots you take on your computer as a .png file. Many websites and software applications prefer to have images as .jpg, however.
