Updating OS - MacBook Air (13inch, Early 2014)

I'm running with macOS Mojave at the minute but want to update to latest OS but struggling as 121GB Flash Storage has 92.58 GB taken up by existing system. This does not leave enough storage to install new OS! Whats my options, advice please..

The latest version of macOS you can install is Big Sur. It requires 35.5GBs of available space to install. You need to free up 8+ GBs.

Other: Contains files that don’t fall into the categories listed here. This category primarily includes files and data used by the system, such as log files, caches, VM files, and other runtime system resources. Also included are temporary files, fonts, app support files, and plug-ins. You can't manage the contents of this category. The contents are managed by macOS, and the category varies in size depending on the current state of your Mac.

The links provided will offer some relief but the issue will be, this tiny Internal SSD of 128 GB is the smallest internal drive offered by Apple.


It should never have been offered at time of purchase IMHO as it is basically unless for any meaningful usages.


If this computer has been upgraded over the years from several previous versions of macOS - this would be the accumulated effects of the space being used on the drive.
