Some Mac users after installing the latest versions of macOS Sierra are faced with the problem of slow Mac performance. If you are one of the unlucky ones whose Mac is running slow, don’t worry. We have several effective tips that will help you to bring your Mac up to speed again.
Remove all unnecessary files and folders from your desktop. It takes a significant amount of RAM memory to display every file and folder on the desktop. Move rarely used files to folders outside the desktop. You will notice that even that will make your Mac run faster.
Make it a rule to restrict your desktop to only the files you need for current work. Before turning off the Mac or at the end of the working day, remove the debris and transfer important items to user folders. In this way your screen will be more selective and the system will work faster.
Get rid of unused Mac startup programs. When you install new software programs, some of them attach themselves to the startup automatically. If you don’t use these programs often, then they just increase Mac boot time, decreasing performance. To stop programs from running at startup go to Apple Menu → System Preferences → Users & Groups -> Login Items. Remove all unneeded programs from the list of Startup apps.
It makes sense to disable widgets and extensions, which you probably don’t use that often. You may not even realize how much memory they eat up. Like startup items, widgets affect your Mac’s speed. Go to the System Preferences → Extensions → Today and uncheck all unused items.
Each running program takes up memory, and therefore a large number of active tasks can greatly slow down your Mac. Close unused applications. However, note that when you shut down an app, it might still be working in the background and take up resources. Open Activity Monitor → CPU tab and sort tasks by CPU usage. Review the list and clear background apps and the most demanding processes.
MacOS keeps a large number of cache files not only related to your browser. Over time they may take up much of your disk space and as a result decrease your Mac’s performance. You can find all the cache files in the folder ~/Library/Caches. To open the hidden Library folder, open the Finder, in the Menu Bar select Go → Go to Folder → type ~/Library and confirm. Find there the Cache subfolder and clear each app’s cache files. For Safari, Chrome and other browsers you can delete cache and cookies right in the Settings section.
