Lots of Running Startup Items

Your Mac may be running slow because it is trying to launch too many programs at once during startup. This is because the programs consume lots of laptop resources at a time hence the long wait. Well, find and switch off unimportant processes launched during the startup. Using the finder or spotlight, open the activity monitor, and click on CPU percentage. All active processes ranked by processor load rating will be displayed. To stop the programs, select the unnecessary programs that create a heavy load on the processor and select ‘quit process’ and further click on ‘force quit.’ To disable unnecessary programs that you don’t want to load at startup automatically, go to the apple menu icon, open system preferences, click on users and groups, and select login items.

Your Startup Disk is Full

A full hard drive is one of the most common causes of a slow mac. Running out of space can cause the applications to crash because macOS is regularly swapping memory to disk with the low initial RAM. To curb the storage issue, first and foremost, check if your disk is full by clicking the apple icon at the top left corner. Go ahead and select ‘About this Mac,’ which will bring an overview of your Mac processor, startup disk memory, graphics, and serial number. Next, click on storage and check the total space you are using. If your storage is almost full, then you will want to free up more memory. You can delete files you don’t need or move some to external storage. You can also use a cleaner app to help you find the junk that might be shrinking your space.

Malware on your Mac

Malware could also lead to the slowdown of your Mac machine. You might have picked up malware from things like clicking on malicious advertising banners or downloading and opening files from unverified sources. You can try removing the malware manually if you know that app that might be causing you problems. Better even, use an Antivirus tool or a cleaner tool to help find the malware for you.

Tip: You should also take steps to avoid future malware infections. For example, limit the app downloads to verified sources only. Simply go to the system settings menu and security and privacy under the General tab. Further, disable the downloads of applications that are not downloaded from the Mac Appstore by ticking ‘allow apps downloaded from Appstore and identified developers.’

Overloaded Cache

Cache majorly consists of temporary data collected from the sites you visit and are stored on your hard drive to speed up internet browsing. However, when those files pile up, your Mac will slow down as a whole. They can be in the form of downloads, messages, web browsers and many more. To clear temporary files and cache, open the finder window and further open the Go tab. Select the library option and open the library folder. Locate the ‘cache’ folder and manually choose the temporary files and caches to clear. To select all, right-click for more options and select move to trash.
