大家不要瞎说了,先好好了解一下Mac OS X 的内存管理:
https://support.apple.com/en-hk/HT201464https://support.apple.com/library/content/dam/edam/applecare/images/en_US/osx/yosemite-activity_monitor-memory.pngMemory Pressure: The Memory Pressure graph helps illustrate the availability of memory resources. The graph moves from right to left and updates at the intervals set in View > Update Frequency. The current state of memory resources is indicated by the color at the right side of the graph:
Green: Memory resources are available.
Yellow: Memory resources are still available but are being tasked by memory-management processes, such as compression.
Red: Memory resources are depleted, and OS X is using your startup drive for memory. To make more RAM available, you can quit one or more apps or install more RAM. This is the most important indicator that your Mac may need more RAM.
上面大家内存都很充足,主观上的性能下降并不是内存导致的。
