A heavy hard drive is the main reason for a slow Mac. Your hard drive gets full when there are so many files and folders saved on it. No wonder you’re confused why is my Mac so slow. Fix: Clean up the hard disk. Not as simple as it sounds, cleaning up a hard disk actually takes a lot of manual efforts. Mar 03, 2020 1. You’ve Got Too Many Startup Items. Nothing slows down a Mac more than having loads of apps and services launching when you press the start button. If you can reduce the number of auto-startup items, you’ll be sure to wait less time, and your Mac will perform better too. How to fix: remove unnecessary login items. Startup Apps are Slowing your Mac down – You can select Login Items in Mac. These items refer to the apps that startup at the time of the system start. – These items load in the background while you continue your work on Mac. They slow down your Mac’s boot time as the system had to load additional apps along with the OS.

A frozen or unresponsive Mac is rare, but Macs aren't immune from some of the same weaknesses as other computers. At one time or another, we've all had documents disappear, programs crash and faced that spinning beachball of dread during a busy working day.
The best thing you can do is not panic, then follow some simple instructions to get up and running again. If you are finding this is happening more often, maybe it's time to look at long-term solutions. Maybe you've not updated your operating system recently? If that is the case, then a new one comes out soon, with macOS Catalina, now is the time to give your Mac an update.
Stop Your Mac From Freezing
A powerful tools to speed up your Mac and fix keeps freezing issues.
At the same time, you may need to declutter the Mac, removing old files and long-forgotten documents to avoid troublesome Mac freezes.
Why does Mac keep freezing?
Macs are fairly powerful, durable devices. It takes a lot to slow them down, or a simple issue of the Mac running too many programs, apps and browser tabs (all of then use processing power). Like with any computer, when too much is stored and too many apps are fighting for CPU processing power, you're stuck with a spinning wheel and your beloved Mac not responding to clicks and pleas.
Apps crashing are some of the most common reasons behind a Mac freezing. Usually, an app freezing won't crash the whole Mac, but that is a risk when your memory is full, or there are lots of applications running at once.
Here are some of the main reasons Macs freeze most of the time.
Main reasons your Mac is frozen
- Too many apps running (this affects memory and cpu)
- Too many background processes (same)
- App crashed (there's a problem with a single app)
- Sluggish browser (too many tabs open)
- Overworked email client (too many attachments)
- macOS loaded with system junk or needs an update
- Not enough free hard drive space
- Hardware problem with your disk or RAM (diagnostics required)
- Malware (the ones that cause Macs to open multiple windows or draft emails, thus overloading the system)
How to fix a frozen macOS
Let's start with a bit of obvious advice: don't panic, don't do anything you'll regret, don't push every button. In this part we'll go over unfreezing a Mac and preventing issues in the future. Depending on your current trouble, we'll try to determine the core reason and what to do in each case.
First aid: How to unfreeze a Mac
First, you need to bring your Mac back to life. When it's unresponsive - either as a result of an app or the computer is struggle to function — you can either click Restart, from the main menu, or press Command-Control-Power (Eject for keyboards and iMacs) to get it to restart.
If neither of those solutions works, then you can hold the power button down which will restart the device. Not an ideal solution, since you can lose anything unsaved, but at least that should restore it to normal.
How to retrieve lost data after the freeze
What if you resurrected your Mac and realized some of the files are missing? Don't worry just yet, install Disk Drill, the world's premier data recovery software for macOS. It was created for the cases when Mac crashed and you lost data and when you accidentally deleted files. Disk Drill is powerful enough to retrieve long-lost, mistakenly deleted files from Macs, external hard drives and USB drives and camera cards. Simply open the app and scan the chosen drive or partition, preview to find exact files you want to restore and restore them.
Now, let's make sure your Mac doesn't make a freeze into a habit.
Most common Mac slow and freeze reasons and fixes
Unresponsive because of a specific app
Apps may running in the background, freeze and crash. Try to determine which apps cause the crash. You start at this: when does the crash happen? If it's when you turn on or work in a specific app, maybe you need to either reset it or remove it entirely.
FIX: To remove apps or set them to back default, use a Mac optimizer app called CleanMyMac, it's has a specific Uninstaller module which can safely perform the task. CleanMyMac is available on Setapp collection and you can use it for free during the trial period.
How to uninstall apps with CleanMyMac:
- Find CleanMyMac in Setapp and launch it.
- Find Uninstaller tab.
- Find the app in question.
- Checkmark it and click Uninstall.
To reset an app, repeat the first three items and then right-click on the arrow near the app name and select Application Reset instead. Resetting an app to default settings and cleaning up its cache can help if you're sure you really need the app and you can't afford to simply remove it.
Also, don't forget to check for app's updates, there's a change your problems sprout from an outdated version.
How to force quit a frozen or unresponsive app
When an app freezes, which becomes obvious when an application is unresponsive in the middle of something, or you are shown the spinning beachball of despair, you can Force Quit (either in the app, from the dock or main menu).
Freeze because of a cluttered desktop
A cluttered desktop can seriously slow down your Mac, and can also cause many problems. That is because every icon on your desktop is an image, not just a link, and it's redrawn each time you start your Mac.
FIX: To clean up your desktop, and organize icons and files, try to use Declutter app. What this app does it groups all the files on your desktop into categories by type (or by any other principle you specify) and thus relieves your Mac from the need to draw 100 image-icons each time.
Freeze because of crushing background apps
This is usually when an app has been running without you realizing it. If your Mac freezes on startup than it's probably one of the startup items, apps that launch when your Mac turns on. You'll need to check on them and remove the extras.
FIX: Stop programs from running at startup on Mac: go to Settings > Users and Groups > Login items and uncheck any app that you don't want to launch when switching your Mac on, or restarting it. This way you'll escape weird crashes that render your Mac frozen.
Freeze because too many apps are running at once
How many are too many? Unfortunately, there is no simple answer; but once your Mac seems to struggle running simple tasks, or slows down when you've got multiple tabs or apps open, it's an indication that it is struggling to cope.
FIX: How to check what apps are running on your Mac right now? Open Activity monitor and take a look at the list of apps. Next to each you can see how much RAM and CPU power they eat up. You can switch between CPU and memory tabs to view each. Those that are the heaviest could cause the problem, so if you're sure you know what that app is, you can quit it.
How to close multiple applications on a Mac: in the Activity monitor, simply select and press the X mark in the top left corner. This will force quit the app. Resort to this only if your app is entirely unresponsive, otherwise use the menu in the top bar with the app's name, next to the apple icon. For instance Chrome > Quit Google Chrome.
In the same way you can manage processes on Mac. Rows without icons are processes. There are system ones and user-generated processes. Don't rush to quit any process before reading a little about it on Google. It might be important.
Freeze because there's no space on hard drive
An overloaded drive can be the reason your Mac fails to work properly and freezes or nearly-freezes. You can check if it's the problem by clicking the Apple icon > About this Mac > Storage. If there's not too many GB left on the free side of your disk, time to clean up.
The easy way to get rid of extra files and give your system a polish is to use CleanMyMac. It's cleaning module is everything you want from a good app: it has a one-click solution and a bunch of semi-automated options for picking out and removing large old files.
To clean your hard drive with CleanMyMac:
- Open CleanMyMac.
- Choose the Smart Scan in the left side
- Click Scan.
- Hit Run.
If you take a few moments to carefully clean up Large and Old files, you'll be gigabytes and gigabytes out, you can't imagine how much garbage hangs in there. From personal experience, it takes about half a year to clutter a Mac with random stuff.
- Click Large & Old Files and click Scan.
- Find what you'd like to remove in there.
- Hit Remove.
Now, here are a few other app suggestions to free up more space.
Gemini — removes duplicated images and similar photos.
Dropshare — lets you quickly move files into the cloud.
When Mac freezes but mouse still moves
A rare case that can signal two things: your Mac is nevertheless locked up and regular solutions fit (restart, check Activity monitor, find problematic apps, clean hard drive)or there's a hardware problem.
There's a way you can check if the latter is the case without taking your Mac to a service store. Install iStat Menus and use its indicators to see if there's an ongoing problem with your drives or battery. Pay attention to the CPU temperature and battery life in particular.
Another way to diagnose your Mac would be to run a specific hardware test administered by Apple itself.
Here's how to run Apple Hardware Test
Preparation: disconnect all external devices except keyboard, mouse, display, and power connection. Put your Mac on a table or anything flat (a soft bed would be a poor choice).
- Shut down the Mac.
- When turning back on, immediately press and hold the D key until you see the Test icon.
- Select language and click the right arrow or press the Return key.
- Click the Test button to begin. You can also press T or Return.
- Upon completion, take a look at the lower part of the window and study the results.
- To quit, hit Restart or Shut Down at the bottom.
How to avoid a Mac freezing
When a Mac freezes, those solutions are reactive, and while you are going to be up and running again soon, you should think about fixes that will help you avoid crashes in the future.
CleanMyMac is one way to cleanup an untidy Mac. Other apps worth installing from Setapp collection include iStat Menus we mentioned before, a handy app that will quickly identify what is absorbing so much CPU processing power and advise those applications are closed. Unlike Activity Menu, iStat Menus providers users with even more useful data, and is available through Setapp, along with hundreds of other apps for Mac customers, all for one convenient price. Remember to pay attention to CPU temperature as a key potential indicator of an upcoming freeze. When it's too high, quit apps and processes that take too much of its power.
That's about it on the matter of freezing Macs, we hope this article has been of help. Every app we mentioned is available on Setapp, an app collection by subscription. More than a hundred ultra-useful tools for all kinds of Mac maintenance, lifestyle, and work tasks. Sign up to try it.

One common problem Mac users experience is overheating. Not when a Mac is new, but when they get older and are full of files, images, videos, and apps that slow down processing speeds, causing them to overheat.
So if you’ve been working away and your Mac is hot to the touch. Like hot enough to fry an egg? Don’t worry; this can be fixed. Or what about when the fans are running so loud it sounds like a lawnmower? Again, both are signs that your Mac is overheating.
An overheating Mac isn’t something you want to try and ignore for too long. Apart from the fact the fans are noisy and distracting, and the hot temperature is irritating, your Mac could - probably will - crash and shut down. If you are working on something and haven't saved recently, you could lose important files. Worse than that, you could risk the Mac suffering irreparable file damage, potentially erasing files, systems, and images you need and don't have backed-up.

Too Many Apps Slow Down Mac Os
Try a set of solutions that help you prevent a Mac from overheating. No more worrying about your computer's health.
Why is my Mac overheating?
Unfortunately, there is no simple answer to this. It depends on how often your Mac overheats.
Assuming this is a recent development, then it could be a sign of an overworked Mac. Too many files, taking up too much space on the hard drive, or too many systems, apps or browser tabs open at once. Especially if they’re heavy programs, consuming a lot of processing space and memory while you are running other apps, such as Spotify and have multiple browser tabs open.
All of that activity can slow a Mac down and cause it to overheat. So most people won’t need to see an expert; this is something that can be fixed at home or wherever your Mac is overheating. Remember, even MacBook Pro’s are relatively compact devices. Excess heat doesn't have many places to go, so when a Mac is overworked, it will start to get hot. What you want to avoid is when it gets too hot, the fans get too loud and processes slow down.
We’ve put together this guide to help stop a Mac overheating and avoid it in the future.
How to stop a Mac from overheating
Firstly, you need to know what is causing the Mac to overheat.
You can get iStat Menus for the job, a handy app to monitor your Mac system stats, control the speed of fans in your Mac, and quickly identify what’s absorbing so much CPU processing power.
iStat Menus can’t lower fans below the speed the SMC would normally use, but it can raise the fan speeds.
If you’re notice issues with fans, resetting your SMC should resolve the problem.
Close all of the apps running in the background and anything else that is using more computing power than looks wise. Unlike Activity Monitor, iStat Menus provides users with more data and insights, making it easier to manage to overheat. You can get this from Setapp, along with hundreds of other apps for Mac customers, all for one convenient monthly price.
Once you know what was causing it to overheat, you should be able to carry on working as normal. If it happens again, you may need to look at over solutions. We have a couple in mind.
The first thing to do is to declutter your Mac. Older Macs are going to be full of documents, apps, images, videos you don't need. Just like a house, when all of that clutter gets in the way, you can’t find what you do need. Your Mac struggles the same way, causing it to overheat.
Too Many Apps Slow Down Mac Without
If while you’re tracking your Mac’s performance with iStat Menus you start noticing signs that gravitating towards overheating, try another app from Setapp collection, CleanMyMac X, a cleaning software.
CleanMyMac comes highly recommended, as the easiest, most efficient way to identify problems, applications, and settings that cause Macs to overheat, then clean them. Both apps are available on Setapp subscription and you can use them for free for a week.
When you’re running a drive cleanup, you might find that the files that take up the most space on your Mac are actually quite important to you. Large video files and huge image folders, 3D projects or movie renders, all kinds of important and increasingly megabyte-hungry items.
Consider moving large files into the cloud. It’s a win-win because if they’re important, this way you won’t lose them and at the same time they won’t take up space on your Mac. Whichever cloud hosting provider you choose, there’s a really handy app to manage and share all your files from the cloud, it’s called Dropshare. It feels like a native part of your macOS and works as a single platform for all cloud storage accounts that you have.
Another way to reduce heavy CPU usage is to fix system issues or lighten up heavy apps. CleanMyMac X has a couple of tools for that. For instance, you can open its Maintenance tab and see Reindex Spotlight, Repair Disk Permissions, and Run Maintenance scripts. Simply select these tasks and hit Run.
After that, run a scan on System Junk and when it’s ready, find the apps with the largest cache (usually browsers and messengers) and clean up their cache.
Important: depending on the app, you might lose histories and preferences, but if it’s the reason your Mac overheats, it’s worth it.
Assuming shutting down browser tabs and apps, decluttering and cloud storing didn’t work; you need to look at any physical reasons for an overheating Mac. Check the following:
- Are you working on a flat surface? Macs more effectively displace heat when on a flat surface, not bed covers or other uneven surfaces.
- Are you outside in the sun? As tempting as it can be when it’s hot, working outside is one of the quickest and surest ways to experience an overheating Mac. In some cases, they will simply crash.
- Are your vents/fans covered? Are you using any third-party devices to manipulate the fans? In either scenario, you risk overheating and need to unplug anything that could influence the fans.
- Are you in a dusty environment? Macs don't do well in dust. Once it gets in the fans, it could cause serious overheating problems.
Assuming you’ve done/checked all of those options and your Mac is still struggling, it’s time to look at an alternative solution. Your Mac could be too full of things that are slowing it down.
My Mac Is Very Slow
How to keep a Mac from overheating
To begin with, you need to define overheating and catch early it when it happens. To monitor the temperature of your Mac, use iStat Menus that we mentioned earlier. It looks into your system and gives you timely updates on CPU temperature, which is a key indicator you need to prevent overheating.
iStat Menus can’t lower fans below the speed the System Management Controller (SMC) would normally use, but it can raise the fan speeds.
Then, you can get timely notifications from iStat Menus when your Mac is near dangerous temperature. This will help you mitigate potential damage or data loss and tone down CPU usage before anything crashes.
That’s about it on the subject of Mac getting hotter than it should. We hope this guide has been of help and if you want to make sure your favorite computer stays cool, get iStat Menus with monitors and CleanMyMac with maintenance tools in Setapp, that should cover your needs.
Prevent Mac overheating
As your Mac is getting older, don't let it get hotter. Here's a toolkit for keeping a computer in a good shape.
In case after both fixes and manual troubleshooting, your Mac is still overheating, you might need to book in with a Mac specialist. More extensive problems may require a trip to a certified Mac Consultants Network retailer, or Mac support from your nearest Apple Genius Bar. Apple Support can also offer help online or over the phone - you just need to book an appointment first. Take care of your Mac and have a good day. Cheers!
