MacBook keeps requesting to force quit all apps due to lack of memory

What do I have to do if my MacBook keeps requesting me to force quit all my apps because it says I don't have enough memory, but it isn't full yet? Im only using 3 apps at the same time

Hi iabc4,


Memory (RAM) and storage are not the same thing.


The solid state drive in your Mac serves as its storage. This is where macOS, along with all of your files, apps and settings, resides. Currently, Macs ship with a minimum of 256 GB for storage.


In contrast, memory (RAM) is where information is stored short term. Whenever you launch an app, its code (instructions) is put into RAM so that the processor or SoC can quickly access and execute it. When an app is running, it can also store certain data in RAM for quick access (for example, parts or all of a file that are being worked on). Currently, Macs ship with a minimum of 8 GB of memory (RAM).


If you get the message that you don't have enough memory, and you're prompted to force quit one or more apps, check which app is using the most memory (or isn't responding), and quit that app. The memory it was using will be given back to macOS, which can then allocate that memory to other apps as needed.


You're most likely running into this error message because one of your apps has a flaw in it, unintentionally created by the developer. This flaw is known as a memory leak, and it occurs when the app temporarily stores data in memory (RAM), but forgets to properly remove that data and give the used memory back to macOS. When this happens, the faulty app appears to just consume more and more memory, until macOS is forced to shut down the app and reclaim the memory it used.

Sometimes you may try to just 'relaunch the Finder' from force-quit menu

to see some effect where desktop items and their representative icons live.


That generally won't restart or effect other items; however may do nothing

to resolve newer macOS issues, could help alleviate other symptoms until a

formal "restart" could occur. ~ Effects differ across various vintage macOS.
