Macbook pro (Retina 2013) running BigSur 11.7.11 has not updated software, time machine is unable to back up. I have checked online and identified the file I need to remove but I can't remove it. My excel etc stops working tomorrow, my mail stopped updating in February. Do I assume my MacBook is now too old to continue?
MacBook Pro 13″, macOS 11.7
Apple released two sets of 13" Retina MacBook Pros in 2013. Catalina is the "end of the line" for the Early 2013 models, and Big Sur is the "end of the line" for the Late 2013 models.
Big Sur is no longer one of the "most recent three" that vendors like Microsoft and Adobe support - having been superseded by Monterey, Ventura, Sonoma, Sequoia, and Tahoe. (Tahoe only supports a handful of Intel-based Macs – and Golden Gate, which comes out this fall, will be for Apple Silicon Macs only.)
Big Sur no longer receives the latest versions of Pages, Numbers, Keynote, GarageBand, iMovie – or Safari. While Microsoft might let you keep using an old version of Excel if it was a one-time-purchase version or if you pay for a subscription, I would not count on being able to successfully reinstall Excel if you ever have to do a "clean" install. Current versions of Microsoft 365 and Office will only install on Sonoma, Sequoia, and Tahoe.
Big Sur is still enough to run
I'm sure that you can also still get versions of the backup programs Carbon Copy Cloner and SuperDuper! that run on Big Sur.

Hi Old-dear!
Officially, yes. A 2013 MacBook Pro cannot officially update past macOS 11 Big Sur.
Excel/Microsoft 365: Microsoft only supports the three most recent versions of macOS. This OS is too old, and Excel cuts off access and updates.
Apple Mail: Mail likely stopped updates because email provides (like Gmail, Yahoo, or Outlook) updated their security protocols (like OAuth 2.0) which the older version of Mail in Big Sur can no longer handle.
As for deleting that file, there could be a number of things causing it. The safest way to delete the file would be to Delete it in Safe Mode.
Turn off your Mac. Turn it back on and immediately press and hold the Shift key until the login window appears. Try deleting the file now. Safe Mode clears system caches and bypasses certain restrictions that might be locking the file.
Also, check your storage. If your Mac is completely full, it will often refuse to delete files. If this is the case, move a few files (like downloads) to a USB thumb drive to free up a bit of space, and then attempt to delete the file.
Hope this helps!
