Troubleshooting with Activity Monitor Activity Monitor, located in the Macintosh HD > Applications > Utilities folder, is particularly suited to troubleshooting performance problems, such as the Spinning Beach Ball of Death (SBBOD) and general system sluggishness. For example, Activity Monitor can be used to determine if your Mac has sufficient resources — CPU, RAM, and free space on your startup disk — for your daily workload. If your Mac regularly performs poorly or your work is frequently interrupted by the SBBOD, your computer may be lacking in one or more of these necessary resources. This is especially true if your work primarily involves notoriously resource-intensive applications, such as multimedia editing, financial modeling, or scientific computing. To learn all that Activity Monitor can do, read its Help: in Activity Monitor, choose Help > Activity Monitor Help. This FAQ discusses using Activity Monitor to troubleshoot performance problems.
