Can I install macOS Big Sur on my MacBook Pro A2015?

I have been using my MacBook Pro (model A2015) for the past 7 years. It has an Intel Core i5 processor, 8 GB RAM, and a 121 GB SSD. Currently, macOS Catalina is installed on it. For the past year, I’ve been unable to install new software or have faced various issues. So, I want to format Catalina and use macOS Big Sur instead.

How much storage might be required to install Big Sur?

Will Big Sur run smoothly on my current configuration?

Your "A2015" model doesn't seem to correlate with any MacBook Pro that I can find.

Please double check at  > About This Mac to find the correct model year of your Mac.

With that info we can tell you exactly which macOS versions you Mac can run.

Before you proceed, you should create a Time Machine backup of your Mac to have on hand and recover from should something go sideways.
