Why is My Mac Running Slow Introduction
Is your Mac not performing as well as it used to? Many Mac users face the dreaded Mac running slow issue, but the good news is it’s not a permanent problem! This article aims to explore the common reasons behind a slow Mac and provide practical solutions to help you speed it up. Whether you’re dealing with background applications consuming resources or outdated software, you’ll find tips to restore your Mac’s performance.
Common Reasons for a Slow Mac
Apps Running in the Background
One of the most frequent culprits of a slow Mac is the presence of multiple apps running in the background. Each app consumes a certain amount of RAM and CPU resources, which can lead to noticeable lag in performance. Even applications that are minimised or running in the background can affect your Mac’s speed, especially if they are resource-intensive.
To manage this, it’s important to routinely check what applications are active. Active Monitor can provide insights into which applications are using the most resources, allowing you to close those that are unnecessary.
Outdated macOS
Keeping your macOS updated is crucial for maintaining optimal performance. Apple frequently releases updates that enhance system stability, fix bugs, and improve security features. An outdated operating system can lead to compatibility issues with newer applications, further contributing to sluggish performance.
To check for updates, navigate to “System Preferences” and select “Software Update”. Regularly updating your macOS can not only speed up a Mac but also protect it from potential vulnerabilities.
Insufficient Storage Space
Storage space plays a vital role in your Mac’s performance. Therefore, if your hard drive is nearly full, your Mac may slow down as it struggles to find adequate space for temporary files and virtual memory. This is especially true for models with limited storage.
To assess your storage usage, go to the Apple menu and select “About This Mac”, then click on the “Storage” tab. Here, you’ll see what’s using up space. Deleting large files you don’t need or transferring them to an external hard drive can help free up storage space significantly.
Hardware Limitations
While Macs are known for their durability and performance, hardware limitations can affect speed, especially in older models. Insufficient RAM can be a significant factor, as it limits the number of applications you can run simultaneously without experiencing lag. Similarly, older processors may struggle to handle modern applications effectively.
If you find that your Mac consistently struggles with performance, it may be worth considering an upgrade. Adding more RAM or replacing the hard drive with a solid-state drive (SSD) for faster data access are both good options to fix a slow Mac.
Check your Mac for Malware and Adware
Though Macs are generally less susceptible to malware than other operating systems, they are not immune. Malware or adware can significantly slow down your machine by consuming resources or causing unwanted background processes to run.
Conducting a malware scan with trusted software can help identify and eliminate any malicious programs that could be causing a Mac running slow. Regular scans can keep your Mac running smoothly and protect it from security threats.

Assessing Your Slow Moving Mac and its Performance
Activity Monitor Overview
Activity Monitor is a built-in utility on Macs that provides a comprehensive overview of how your system is performing. It displays real-time data on CPU, memory, energy, disk, and network usage, allowing you to identify any anomalies or applications that are taxing your system.
To access Activity Monitor, open Spotlight with Command + Space and type Activity Monitor. This tool can help you quickly determine which applications are responsible for any slowdowns, enabling you to take action accordingly.
Storage Management Tools
macOS includes built-in storage management tools that can assist you in optimizing your storage and, consequently, your Mac’s performance. By accessing the Storage Management feature from the Apple menu and selecting About This Mac, you can view recommendations for optimising your storage, such as emptying the trash and reviewing large files.
Utilising these tools can lead to a more organized and efficient system, helping to prevent future Mac running slow issues due to storage limitations.

How to Fix Mac Running Slow
Close Unnecessary Applications
One of the simplest steps to improve your Mac’s performance is to close applications that you are not actively using. Each running application consumes system resources, which can lead to a bottleneck effect when you have too many processes running at once.
To close an application, you can right-click on the application icon in the Dock and select Quit. Alternatively, you can use the Command + Q shortcut to close the currently active application. Regularly practice this habit to keep your Mac running smoothly.
Update macOS and Applications
Regularly updating your macOS and applications is a key component in maintaining performance. Software updates not only bring new features but also improve the efficiency and security of your applications and system.
To update your applications, check the App Store for any available updates. Additionally, enable automatic updates for both macOS and your applications, ensuring that you always benefit from the latest improvements without needing to remember to do it manually.
Free Up Storage Space
Insufficient storage can lead to significant slowdowns. To free up space, consider deleting files you no longer need, utilising cloud storage solutions, or transferring large media files to external drives. You can also use third-party applications designed to help clean unnecessary files from your Mac.
Regular maintenance in this area can keep your storage levels healthy, promoting better performance over time.
Upgrade Hardware Components
If your Mac is still underperforming after following software optimizations, it may be time to consider hardware upgrades. Adding more RAM can provide a significant boost in performance, especially for tasks that require heavy multitasking or use of resource-intensive applications.
Another popular upgrade is replacing the traditional hard drive with a solid-state drive (SSD). SSDs offer faster read/write speeds, which can drastically improve boot times and application loading times.
Run Malware Scans
To maintain optimal performance, it’s essential to regularly run malware scans. Choose a reputable antivirus or anti-malware software that is compatible with macOS and perform scans at least once every month. This helps to ensure that your system is not being adversely affected by any hidden threats that may be causing slowdowns.
In addition to scans, being mindful of the websites you visit and the applications you download helps in preventing malware infections in the first place.
What to Do if Mac Running Slow after Update
Sometimes, a shiny new macOS update can leave your MacBook feeling sluggish instead of supercharged. Don’t worry – this is often temporary and fixable!
Firstly, give your Mac some time; after an update, it might still be re-indexing files for Spotlight search, which can slow things down. If the slowness persists, reset your System Management Controller (SMC) and PRAM/NVRAM, as these can help resolve performance hiccups.
Secondly, check for app compatibility – older apps might need updates to work smoothly with the new macOS.
Lastly, consider reinstalling the update, as issues during installation can cause performance drops. If nothing works, bring your Mac to a professional, such as Tech Resolvers Norwich, to ensure the update didn’t introduce deeper software or hardware conflicts. We can help you fix these and also identify which Apple Mac you have if you can’t find the model number.
