No computer will run fast forever – sooner or later they all start slowing down. If your beloved old Macintosh seems to be lagging, freezing and acting weird, it’s high time to boost its performance and make it run like new again.
In this troubleshooting article, we’ll cover eight important reasons why your computer may be very slow and offer some solutions to bring your Mac back to life. But if you’re inexperienced and these tips seem complicated, you can use Movavi Mac Cleaner to speed up your computer in just a few clicks. You’ll find a tutorial at the end of this review on how to use this handy app.
Your Mac’s performance really depends on the amount of free hard disk space. When available storage runs low, the computer slows down dramatically. Сheck the free disk space by going to Apple menu >About This Mac. Then open the Storage tab to see how much space is currently being used. For decent performance, an average Mac needs about 10% of its storage free. If you have less, chances are your computer is running slower than it could be.
Solution: Remove unnecessary files
To clean the hard drive manually, find and delete unneeded applications, videos, photos, and music files, as well as installer files with the .dmg or .pkg extension. Removing files from Trash will also help you to free up space.
Old software can cause all sorts of problems: slowdowns, unexpected freezes, app crashes, and other performance issues. To prevent this from happening, Apple regularly releases new versions of their operating system. To check if your version is up-to-date, open Apple menu >About This Mac >Software Update.
Solution: Update the operating system
Updating your OS is easier than it sounds. Newer versions will usually improve the Mac’s performance speed and stability as well as deliver new functionality. To schedule your computer to check for updates automatically, open System Preferences >App Store and check Automatically check for updates.
When you start your Mac, a number of apps launch in the background. These significantly increase the startup time and slow down your computer. Stealthier programs don't ask your permission and just configure themselves to launch on startup, so you may not even know about them and keep asking yourself "Why is my Mac so slow?".
Solution: Remove unnecessary login items
Fortunately, you can remove apps from the startup list. Open System Preferences >Users and Groups. Choose your username and click the Login Items tab. Now you can uncheck the programs you don’t want to launch at startup.
All open applications consume memory and CPU resources. When you have too many apps running, your Mac’s performance suffers.
Solution: Stop resource-hungry processes
Activity Monitor is a handy built-in tool that will help you find out which programs are using the most system resources. Go to Utilities >Activity Monitor – you will see all the processes running at any one time. Pay attention to the CPU and Memory tabs at the top of the window. In these tabs, you can sort all open apps by the amount of system resources they are using. To force an app to stop, click it once in the list and then click the x icon in the upper left corner. Be careful, don’t close anything you are unsure about!
Caches and logs are temporary system files that make your system and apps run smoothly. However, these files tend to accumulate over time and take up too much disk storage, which makes your Mac extremely sluggish instead and working with it annoying.
Solution: Delete old temporary files
Regularly deleting old caches and logs helps your Mac run faster. To clear out caches manually, click Go >Go to Folder. Type in ~/Library/Caches and hit Return on your keyboard. In the window that opens, you will see lots of folders. Open each folder and delete everything in it (this way is safer than moving all folders to the Trash at once). To clear out logs, do the same in ~/Library/Logs.
The more RAM your machine has, the faster it works and the more apps it can run simultaneously. Lack of memory inevitably leads to longer loading times, app freezes, and even crashes. To check if you have enough RAM, open the Activity Monitor and click the Memory tab. Take a look at the chart in the lower part of the window. If it’s green, your RAM doesn’t need upgrading. It it’s orange or red, then you need to take some action.
Solution: Upgrade your RAM
Installing more RAM modules in your computer is a very effective way of improving performance, but it may cost you a pretty penny. If you are unsure about how much memory you need to add, ask a tech-savvy friend or consult a technician at a computer store.
When you surf the Internet, Safari collects data about the websites you visit. This information gradually accumulates and may eventually slow down your browser’s performance. So, if you can’t stand Safari’s slowness, clean out the data it has been collecting for months or even years.
Solution: Clear web browser cache and history
To clear the Safari cache, open Safari menu >Preferences and click the Advanced tab. Then check Show Develop menu in menu bar. In the menu bar, click Develop >Empty Caches.
To delete browser history, click the Safari menu >Clear History. Select the appropriate time period and click Clear History.
Mac OS X has some eye-candy visual effects (for example, when you minimize a window to the Dock). However, these animations consume system resources and may slow your computer down.
Solution: Turn off animations
Open System Preferences >Dock and uncheck these checkboxes: Magnification, Animate opening applicationsAutomatically hide and show the Dock. Then click Minimize windows usingand choose Genie Effect instead of Scale Effect.
