No. It won’t install.

• Storage space needed is 35.5GB. So, no, it will not install. Uninstall large, unnecessary files like Movies, TV Shows, and Virtual Machine. (See Screenshot).

Ideal Requirements

• RAM: How much RAM do you have installed? 8GB would is the minimum, ideal amount (but16GB would be better).

1. Go To: Apple menu
2. Select: About This Mac
3. View: total RAM

• Hard Drive: Seeing you have a 128GB Hard Drive, you would be fine, as long as not much is stored on it, but rather is accessible from an external source (ie hard drive or cloud storage) 256GB would do, but 512GB would be better)

You are welcome.

About One of my Macs:

I have a secondhand 13” 2017 MBP that has 8GB of RAM, and a 128GB HDD. So, I’m sticking with Catalina on it, myself. It is for extra use. My other Mac is much more high-end and suits my needs. So, I use Big Sur on that one.
