The Memory inspector can't really be relied on right now because it includes cached memory in the "used" total. Basically it's reporting Total - Free, where free is completely unused by anything. In reality, you actually have Free + Cached available for use as the kernel will prioritize application memory requests over background kernel cache. When looking at top you should see the following memory categories: - Total - All memory present on the system - Free - Memory that is entirely free and clear, not used by anything - Used - Memory being directly used by applications and kernel - Buff / Cache - Memory that the kernel manages to keep frequently accessed data The Buff / Cache is what usually gets ignored and / or misinterpreted. While it is being used by the kernel, it's also available to be reclaimed by applications once the Free memory is exhausted. So when looking at top, the memory you have available for application use is Total - Used, which should equal Free + Cached. Memory inspector misreports this.
