Your profile indicates you have a 17" MacBook Pro. The last 17" MacBook Pro was introduced in 2011 and discontinued in 2012. Which makes it 10 years old at the oldest or possibly 9 years old at the newest. It's obsolete. High Sierra 10.13.6 was the last macOS version that would run on it.



Apple doesn't officially state it, but most all of their products are considered legacy after 7 years and obsolete after that. There have been exceptions but very few of them. When a product reaches "legacy" it will no longer run the latest operating system version but may still be supported partially with the previous operating system. Once you get to the current minus 2 versions you are pretty much obsolete. At this point you are current minus 3 and by this fall minus 4. Most software developers will refuse to support operating systems at current minus 2 and may release new versions that will not even install on such an old version. You won't see any security updates either which means you could be vulnerable to attack online.



Technology is always moving forward. Today's computers are much improved over what was available ten years ago. Software moves forward constantly. If you want new features, you will need to buy new hardware.

The last 17-inch MacBook Pro was introduced in Late-2011. Big Sur requires a MacBook Pro introduced in Late 2013 or newer.



High Sierra (10.13.6) is the end of macOS upgrades for your MacBook Pro.

Two folks have provided the unfortunate answer you are seeking. However, it is a bit disconcerting that the awareness to having missed the upgrades to Mojave, Catalina and Big Sur has just popped on the radar. Has this machine perhaps been out of service for an extended period? New Mac user just getting started on an old machine?
