Is a certain app or process causing excessive CPU load on your Mac? If a process is consistently taking up a high percentage of processor power, it may prevent other apps, or macOS itself, from doing all that it needs. The following is an overview of the various tabs in Activity Monitor, as well what to look for in each category: CPU

Processes are apps that you see, and those that run in the background your Mac runs dozens of different processes.Īctivity Monitor shows all processes in real-time. The information is sorted into different tabs that display processes in the category specified, and each one can help you narrow down the issues you’re having.

From the View menu, select Update Frequency, and then set it to its lowest value, 5 seconds.This utility gives you a live view of your Mac’s processor, RAM, energy, disk, and network usage. You can find this utility in Applications > Utilities.įirst, set up Activity Monitor to make it easy to use: Is your Mac using too much RAM and running out of memory? Are certain stuck processes causing your Mac to slow down? macOS has a useful utility called (). If a restart did not solve your issues, or only fixed them for a short time, you should check how your Mac’s hardware is being used. And at other times, even keyboards or mice can have issues that conflict with your Mac.
Sometimes problems with external hard drives can slow down Macs, as the Mac is trying to read and perhaps index the drive for Spotlight searches.
If the restart process takes a long time, try again after disconnecting any peripherals connected to the computer, especially hard drives. If the startup process takes longer, this doesn’t give clues as to what’s wrong, but it does suggest that something is happening when the Mac loads macOS rather than later. Most Macs, regardless of configuration and operating system version, should be up and running in no more than one minute or two Macs with SSDs should go to the login screen in seconds. The amount of time it takes for your Mac to go from black screen to loading your desktop can also be a good indication of where to look for issues. When you restart your Mac, it clears the memory and forces any processes that may have been stuck to reload.
Restarting your Mac is quick and easy, or at least it should be. () tells you all about backing up your Mac. Ideally, you should use both: if you have multiple backups, and your Mac fails, this is the best way to ensure that you don’t use data: sometimes backups get corrupted, or their drives fail too. You can use Apple’s Time Machine and Intego Personal Backup to back up your Mac. If there are hardware issues, then your Mac could potentially stop working, or your drive could be corrupted. Whether the cause of your Mac’s performance issues are hardware or software, the first thing to do is ensure that you don’t lose any data. When your Mac is getting slow, follow these troubleshooting steps to find what’s wrong and hopefully make it faster. This is the only way to see if a solution is just a temporary fix or a permanent one. When troubleshooting a Mac, you go through a process of elimination. And troubleshooting can take a long time: you try a solution and then test to see if it works, sometimes waiting hours or even days to be certain. The operating system or specific applications are not working as they should. One of the components in your Mac has failed or is failing. New versions of macOS are generally compatible with Macs going back several years, but if yours is among the oldest supported by the current operating system, it may not have what it takes to be fully efficient. At some point the processor, drive, amount of RAM and/or graphics card simply can’t keep up with the latest software.
