Detect & kill demanding processes

Using a demanding process can quickly slow down a Mac and cause it to run hot. While this can occasionally happen with legitimate tasks, intense processor usage is usually caused by tasks that your computer does not need to handle. Fortunately, it is easy enough for us to detect and stop these processes in order to speed up our computers.

The first step is to access the Activity Monitor on macOS. To do this, go the menu bar on the top of your screen and click ‘Go’, then select ‘Utilities’ and open Activity Monitor. In the CPU tab at the top of the window, you should be able to select ‘% CPU’ which orders all of your active processes based on their processor usage. The higher %CPU readings are more likely be slowing down your Mac, so look out for programs that seem unnecessary—such as those related to macOS like WindowServer, kernel_task, or sysmond—as these are necessary system processes. Once you detect a program that may be causing problems, just quit it and watch your Mac speed up in no time!

Remove unused apps

Removing unnecessary applications can help to speed up your Mac. Going through the Applications folder in Finder can help you find which apps you no longer need and deleting them will free up space on the hard drive. To start, go to Finder > Applications and then click the grid icon to sort all your installed programs by the date last opened. This way, you’ll be able to quickly identify which ones haven’t been used in a long time and drag them into the Trash folder. Remember to empty the Trash afterward to permanently remove them from your Mac.

It’s important to regularly check for unused apps as this will also improve system performance since not only will it make more space available on the hard drive but also prevent RAM-consuming processes from running in the background which can bog down your machine. This simple process of sorting, removing, and disposing of unused apps every few months or so doesn’t require much effort but could make a huge difference in keeping your Mac running at peak performance levels. It’s a task that should definitely be included in any regular maintenance plan for optimal efficiency.

Upgrade your RAM

When it comes to speeding up your Mac computer, an often overlooked factor is RAM. RAM stands for Random Access Memory and it serves as the main memory for your machine. This is what allows your computer to quickly access and store temporary pieces of data, which can significantly speed up overall performance. If you want to experience a noticeable increase in speed and responsiveness from your Mac, then upgrading the amount of RAM it has is a great step.

For example, adding RAM to a system with just 1 or 2 GB can have a huge positive impact on its performance. In most cases, 8GB or 16GB should be more than enough for general use. Professional video editors and programmers may need even more though. Additionally, it’s important that you regularly check your RAM for errors that might be causing slowdowns. Fortunately, our guide to upgrading RAM on Macs makes doing this easy so you don’t have to worry about any technical difficulties getting in the way of maximum speed and efficiency.

Upgrade to an SSD

The move from an outdated HDD to a modern and powerful SSD offers the best performance boost you can get for your Mac. The leap in speed is undeniable; from HDD’s 100 MB per second to SSD’s 3500 MB per second capabilities, there’s no question that your computer will be working faster than ever before. Now, thanks to reduced prices of SSDs, this upgrade doesn’t need to break the bank either.

With an SSD upgrade, you can expect loads of your data and programs happening lightning fast — within seconds. What once took minutes to open will now happen in a fraction of the time! Plus, unlike HDDs that produce a lot of noise due to their disc spinning mechanism, SSDs are mostly silent and don’t use as much energy— saving even more money. All these features altogether create one substantial upgrade: giving you more power with minimal effort required.

You should reset PRAM and SMC

Resetting the SMC and PRAM (Parameter Random Access Memory) is an essential task for maintaining optimal performance on your Mac. If your Mac is having any performance problems, like slow downs or shut downs, you can often solve them by resetting the parameters of your system. The System Management Controller (SMC) of your Mac controls basic functions, such as Wi-Fi connectivity, power management, and hardware connections. The PRAM contains crucial settings like volume, keyboard lighting, and performance information that play a major role in how your machine runs.

To reset the SMC and PRAM, you will need to restart your computer in Recovery Mode so that you can access the startup utility launching tool from which you will issue the appropriate terminal commands to reset each component as needed. Once this has been done, normally everything should be running properly again. Realistically though there’s no guarantee that all computer related issues will be resolved through this process but it won’t hurt either way. Resetting these components occasionally provides regular maintenance of sorts to help avoid any future crashes or glitches with your Mac’s operating system.

Clear Mac cache

Cached files are intended to improve the speed and performance of Mac computers, as they help load data more quickly. However, if these cache files are left to accumulate over time, the device can become bogged down with excess junk data that won’t only take up valuable storage space but will also slow down your computer’s processing speed. To remedy this common problem, it is essential to regularly clear your Mac cache in order to ensure smooth running operation.

Clearing caches manually poses some difficulty as there are certain places where caution must be exercised when deleting or modifying files. To avoid any risk of wiping important data unnecessarily or causing system damage, it is best practice to use dedicated optimization apps like Avast Cleanup for Mac which can automatically scan and detect outdated or redundant junk files that have been clogging up your Mac’s hard drive without you even knowing it was there.

Remove browser extensions

Browser extensions are a great way to enhance your web browsing experience on your computer. However, having too many installed can slow down the performance of your Mac significantly. Therefore, it is important to only keep the extensions that you actually use and remove any that are no longer necessary.

To start with, it is a good idea to go through the list of installed extensions and decide which ones you still need. If there are any superfluous plugins which you merely have bookmarked and do not actively use, such as ChatGPT, they should also be removed. Most browsers have a useful tool for this purpose: simply click on the jigsaw-shaped icon in the top-right corner of the browser window and select ‘Manage Extensions’. From there, you can either disable or completely remove any extension that isn’t needed anymore. Doing this periodically will help maintain your Mac’s optimal performance and ensure its longevity.

Sort your desktop files

It can take only minutes for our desktops to become cluttered with icons and documents that make it difficult to locate just what we need. However, an overcrowded and unorganized desktop can have a negative impact on both our efficiency in finding files and our computer’s performance. This is because each individual icon on our desktop takes up space in our Mac’s memory, leading to slower loading times and increased background RAM consumption.

Fortunately, cleaning up and organizing your desktop doesn’t have to be an overwhelming task. Create folders for specific categories such as ‘Work’ or ‘School’ and move all relevant documents into each respective folder. Not only does this keep everything neat and organized, you also reduce the number of icons on your screen so your Mac is able to load faster. Additionally, if you want to have access to a certain document but don’t want its icon visible on your desktop, you can right-click the file and select ‘Get Info’, which will allow you to keep files in their designated folder without needing them displayed cluttering up your workspace.

Verify if your hardware is experiencing any issues.

Hardware failure can often be a sign that your computer is not performing optimally. With the advent of digital technology, our computers have become incredibly complex systems that require precise maintenance and attention. Unchecked hardware can lead to serious performance issues, glitches, and even crashes or blue screen errors. It’s important to regularly check your hardware components to ensure they are operating correctly and efficiently.

The first step in checking for failing hardware is to monitor the CPU temperature. If you consistently see temperatures over 70-75 degrees Celsius, then there may be a problem with the cooling system or other components that requires investigation. You should also keep an eye on hard drive usage: gradual increases in read and write times could indicate something like a bad sector or corrupt file. Finally, pay attention to any strange noises coming from the system – as these could indicate defective fans or drives. Taking these precautions will help you prevent minor issues from becoming more severe problems down the road.

If needed, utilize Disk Utility

Disk Utility is an ideal tool for anyone experiencing issues with their hard drive. The First Aid feature within Disk Utility can identify and repair disk problems. It can even detect imminent hard drive failure and notify you in time to back up your data, so you don’t lose it.

Accessing the First Aid feature in Mac OS X Sierra is relatively simple. Firstly, you open Finder, then select Applications > Utilities and then launch Disk Utility. Once launched, you can choose from one of several tasks such as verifying or repairing the disk and its directory structure, enabling or disabling journaling or partitioning a drive. This utility also allows user to keep track of their system’s performance by measuring boot and load times. Performances were tested using internal lab tests from August 2015 with fresh boots given every time before executing tasks to avoid other factors or applications affecting the performance reported times. Although actual performance might vary according to individual system configuration, this utility provides good insight into a system’s running smoothly or needing attention for further checkups.
