Over time, due to the accumulation of debris clog the system (including temporary files, various caching, streaming data, etc.), Mac's performance may be slower than normal start.
In addition to lack of disk space, RAM (or lack of disk space) is the second leading cause of speed is decreased.
When you open an application, its binary file is loaded from memory into RAM, so that the CPU can acquire and execute code. As with all multi-tasking operating system, macOS can manage on your behalf dynamic RAM, so you can run more applications simultaneously, and can not accommodate more applications.
macOS memory management works well - most of the time, Activity Monitor application to display RAM utilization close to 100%. This is by design - based on experience, has been packaged into RAM hope because, since the content is loaded from memory than from RAM to get content slowly.
But sometimes macOS memory management may not be able to clear the contents of RAM to load, so that resource constraints. macOS system cache will be refreshed periodically, but not always possible to empty the cache correctly.
Either way, this will cause your machine starts to pause and show signs of performance degradation, such as a longer application load times and slow multitasking. Follow iDB learn together, we will teach you how to manually force macOS Clear RAM and disk cache refresh.
How to accelerate Mac
You can work around the problem by restarting or deceleration does not restart.
With the restart
Mac is designed to run for weeks and months without restarting, but I still have to turn off your computer at the end of the day, and restart your computer in the morning, because doing so would prompt emptied of all content macOS of RAM and clear All disk cache.
If you're uncomfortable using Terminal command line, you should restart your Mac once a day, this will be good.
No Restart
In some cases, you may not be able to restart and clear the RAM disk cache, but this is the Terminal application. Thanks macOS the command line, you can force macOS of RAM and cache cleanup process into practice.
1) Open the "terminal" from the "Application / Utilities" folder.
2) by typing the following command in the "Terminal" window to manage privileged EXEC purge command, and then press Enter to run it:
sudo purge
You may be asked to enter a password Mac account.
除非您的Mac的内存和存储空间非常少，否则清除RAM和磁盘缓存内容的时间应不超过几秒钟。操作完成后，您不会看到确认消息。
如果您不想通过重新启动计算机来中断重要工作，则命令行方法特别方便。只需加载终端应用程序并执行上述命令，即可使Mac功能得到提升，而无需重新启动。
是时候升级RAM / SSD了吗？
当然，对于所有Mac速度缓慢的问题，purge命令并不是神奇的补救方法。实际上，您的Mac没有足够的RAM用于您通常使用的RAM。
如果您是在专业应用程序中编辑照片/视频的人，则将需要尽可能多的RAM。如今，最少要有4 GB的空间用于光使用，建议8GB RAM用于日常的多任务处理，例如上网，检查电子邮件，使用社交媒体，消费内容和编辑媒体。
除了RAM外，您还可以为Mac配备更快的SSD，这将立即为您带来明显的性能提升-特别是如果您来自基于HDD的Mac。
