It's not uncommon to run out of space on a Mac, but Apple's inbuilt storage management tool makes it easy to quickly delete large files and apps, and offload data to the cloud. Up until recently, Apple sold MacBooks with 128GB of storage as the base variant. While it was a popular choice among users who wanted a cheaper model, it also meant that storage was very limited. While Apple now offers 256GB as the base variant for Macs, it's still far behind Windows laptops where 512GB of storage is the norm.
When a Mac's storage is close to full, Apple will begin displaying warning messages asking users to free up space. While the Mac still remains functional, it can begin to slow down if there isn't enough available storage. Apps that save temporary files on a Mac may begin to get sluggish when there isn't free space. It may also become impossible to download larger files. Apple's macOS system updates also need a fair bit of free space to be installed. For instance, macOS Monterey needs at least 26GB of free space, while those upgrading from older releases need at least 44GB of storage to install the update.
