8 problems may cause your Mac running slow

Sometimes you may find your Mac run slowly for no reasons, but if you carefully enough you will find out there are many reasons. Here are some solutions for these major 8 problems.

1.Spotlight Retrieving


As Mac search engines Spotlight will index file, as well as the Mac is running slow. Some people think that the reboot can solve a lot of problems, but here is not applicable, and reboot the system even worse in the Spotlight indexing process. In general, using the SSD for Mac Spotlight indexing will not have much impact, ordinary hard disk may be worse than SSD.

Open the Spotlight, if it is indexed content, we will see a progress bar as well as the tips of the index. For this moment pause is not recommended. General index update takes will not take too long so just wait for moment.


It’s a fact of modern life: Macs can run slowly for seemingly no reason, but chances are there is a reason the Mac is running so poorly and we’ll cover the most common reasons, how to know if each reason is causing the slow down, and most importantly, how to fix it. If your Mac is running slowly and it feels like a snail could launch a new app or load a web page faster than the computer could, read on.

Solution: Wait for Spotlight to finish indexing, it usually doesn’t take too long.

2: Software Update Loading
Whether the Mac is newer and updates through the App Store, or older and goes through Software Update, either of these processes can cause a temporary slowdown to the system while they launch in the background, query for available updates, and

How to Know: After a minute or so you’ll get a Software Update notification



Solution: Keeping system software up to date is one of the best things you can do as part of a Mac maintenance routine. Let it run, install the updates, and reboot.

3: Low Disk Space
Anytime any computer is running very low on disk space, the computer will slow down dramatically, and Macs are no different. The reason is fairly simple; between the operating system and all your apps, a lot of temporary cache files are generated, and things are swapped in and out of memory and to the disk as needed. If your disk is full, those actions take longer because older cache files and swap files must be deleted before new ones can be generated, which creates a stall before any further system process can be taken. This whole thing can be painfully slow especially on traditional hard disk drives, and can leave any Mac feeling as slow as molasses.

How to Know: Checking available hard disk space is a cinch, just go to the desktop and open any folder, then pull down the “View” menu and select “Show Status Bar”. Now look at the bottom of the Finder window you opened, if the number of available space is less than several GB’s, you should take action. If the number is 0, you need to take immediate action!



Solution: The best thing to do is clear out files you don’t need any more. First, go to your Downloads folder and remove stuff you don’t need because it can fill up awfully quick if you don’t clear it out yourself. Next, recover disk space by downloading a free app like OmniDiskSweeper to discover where all your storage went. Delete unnecessary files. When finished, reboot the Mac, because rebooting will cause temporary caches to clear out and that can often free up space as well.

4: Out of RAM
There is no bigger slowdown to encounter than when you run out of available RAM. When you run out of RAM, virtual memory takes over, and virtual memory is slow because it relies on your hard disk to store information needed for apps and OS X to run rather than keeping that information in super-fast RAM.

How to Know: Open “Activity Monitor” from the /Applications/Utilities/ folder, click on the “System Memory” tab at the bottom, and look at the colorful pie chart. If you don’t see any green, you’re running low on “Free” memory, and you can check just how low by looking at the “Free” item. “Inactive” is another potentially valuable resource to look at.



Solution: Quit apps that are no longer in use, and try relaunching ones that you are using. Web browsers in particular, like Safari, Chrome, and Firefox, will often consume more RAM than they need to the longer they are left open, as past web pages are stored in memory. Also, some websites have memory leaks. Quitting and reloading a web browser can often free up a ton of RAM.

5: High Processor Utilization
If an app or process is consuming a lot of your processor, other things going on with the Mac will slow down dramatically. Tons of different things can take up CPU, and though most are temporary as a process executes and completes, some errant processes go wild and continue to hog far more CPU than what is appropriate.

How to Know: Again, open “Activity Monitor” from the /Applications/Utilities/ folder, but click on the “CPU” tab at the bottom. Watch the “% Idle” for a few seconds, if that number is consistently below 60 or so, you have something that is eating up your processor.



Solution: Still in Activity Monitor, click the “CPU” item at the top to list items by processor usage. The topmost item(s) will be your culprit, if those apps or processes aren’t in use, quit them to free up CPU.

6: Too Many Apps Open at the Same Time
This is simplified way of saying you’re either out of RAM, have an app being a CPU hog, the disk is thrashing, or any number of other problems that can occur when you simply have way too many apps open and running at the same time.

How to Know: The easiest way to tell is if the OS X Dock is a plethora of every app installed on your Mac.

Solution: Quit apps you aren’t using, the more the merrier.

7: Not Enough RAM for Your Needs
Speaking of running out of RAM and having too many apps open, it’s possible that you simply don’t have enough RAM to use your Mac at optimal speeds for your usage patterns. Thankfully this is very easy to determine, find out how to tell if your Mac needs a RAM upgrade by reading this great guide.

8: Your Desktop is Full of Icon Clutter
Did you know that having a desktop full of a billion icons slows down a computer? This is because each icon gets drawn as a window, and OS X renders a preview of the icons and their contents, each of which takes up resources to redraw as things are moved around.

How to Know: Your desktop is a disaster of files, documents, folders, with more icons than wallpaper visible.



Solution: Tidy up your desktop, ideally down to just a few select important things. If this sounds daunting, even creating a new folder called “Desktop Stuff” and throwing EVERYTHING from the desktop into it will dramatically speed things up. Also, there’s some great apps out there that will tidy up your desktop for you, try those out if you’re bad at managing the desktop clutter, or consider hiding the desktop icons completely.
