MacBook Air is lagging and not updating despite good storage and Wi-Fi

The tag line on your post says that you have a MacBook Air running macOS 14.5 (Sonoma).There are newer releases of Sonoma, the latest of which seems to be macOS 14.7.6 (Sources: MacTracker and What's new in the updates for macOS Sonoma - Apple Support).

To update past Sonoma, to Sequoia, you would need either an Intel-based 2020 MacBook Air, or a MacBook Air that has an Apple Silicon (M1 – M4) processor.

From your above, it is most probably because of the following

1 - the computer does not have at least 50 GB of Empty Space

2 - there are Third Party Applications installed on the computer that is interfering with what you want to do

In either case suggest this

Restart in Safe Mode. This will perform a Disk Repair, clear cache files and only load Apple Software, extensions and fonts. The boot up will be slow and can take some time - Normal.

Safe Mode will also eliminate Third Party Software, extensions and drivers from loading. It will only load the Minimum amount of Core Apple Processes to allow the the computer to function at a reduced Level of Performance 

Does the issue present in this mode ?

Sometimes a Safe Boot followed by a Normal Boot will just put things right.

If not - there could be something in the main User Account playing up. To further isolate this - Set up users, guests, and groups on Mac. Then log out of the Main User account and log into the dummy account and test again if the issue persists.

If the issue is present in the dummy account - then, this appears to be a System Wide issue on the computer.
