Mac running slow, how to speed up it?
Whether you want to speed up your lagging MacBook Pro, MacBook Air, or Mac mini, the following ways will give you a hand.
If your Mac begins to run slowly all of a sudden, you can restart your Mac to check if it's just a system bug. Or, if your Mac running slow after an update, check if your Mac is too old to be compatible with the new OS version first. And it is also advisable to test the disk speed of your Mac if you are a professional in this field.
Then, you can follow these solutions.
Quit apps and browser tabs you're not using
If you have opened too many apps at a time but only use a few of them, the left ones will keep running in the background and consume the memory.
So, get into a habit of closing the apps and browser tabs that you're not using.
Free up more disk space
Check the disk storage on your Mac (Open the Apple menu > About This Mac > the Storage tab). If there's less than 15% free space on your Mac, free up more storage space.
Usually, the accumulation of junk files, caches, useless apps, or DMG files takes up too much space on your Mac. You can remove some useless apps, such as uninstalling Honey on your Mac. Also, you can delete the downloads that accumulate on your Mac.
Besides, remember to empty your Trash in the routine. The deleted files in Trash are still on your startup disk and occupy your disk space.
If you have many videos and other storage-consuming files, you can move them to your iCloud or store them on an external storage device.
Manage your login items
For convenience, you set some programs to automatically open whenever you log into your Mac. But multiple apps running simultaneously in the background will decrease the Mac performance.
You can open Users & Groups in System Preferences. Then remove the apps that are not so necessary for auto-starting when logging in.
Update your Mac and apps
The outdated OS and apps will drag Mac's performance down. Update your Mac usually can update both the operating system and the first-party apps, such as Safari, iTunes, Notes, etc.
To update your Mac, you should click the Apple menu > System Preferences > Software Update. Then check if there's an update or new macOS version available. Next, click Update Now or Upgrade Now to update your Mac.
Upgrade your RAM
If your Mac has insufficient Random Access Memory (RAM), your Mac will run slowly.
That's because the RAM offers storage for ongoing processes. If not have enough RAM for Mac OS to run multiple or intricate tasks, your Mac will slow down.
To check how much your RAM is and its usage, you need to open Activity Monitor (Finder > Applications > the Utilities folder). Move to the Memory tab in the Activity Monitor window. Here, the Physical Memory is your RAM.
If almost all the RAM is used, close the process that takes up too much memory. If your RAM is less than 4GB, you'd better add more RAM. You can ask someone professional or go to a repair center to install RAM.
