While many of us are constantly glued to our devices, we do find ourselves in situations we can't handle. We may have been using the same MacBook for years but our devices rarely cease to surprise us. Sometimes we are unable to deal with error messages in times of need. This is a serious issue as individuals today function as efficiently as their devices.
This article takes you through the possible courses of action you can take to deal withcommon Mac error messages.
If you get error messages when upgrading Mac, you need to turn to the page:Fix Common Issues in Mac Upgrading.
- Message 1: 'Your disk is almost full'
- Message 2: 'The application * program name* is not open anymore'
- Message 3: 'Safari Web content quit unexpectedly'
- Message 4: Enter password for your iCloud ID
- Message 5: 'You can't open the application because it is not supported on this type of Mac'
- Message 6: Mac displays a folder with a question mark
- Message 7: Mac OS X Kernel Panic
Message 1: 'Your disk is almost full'
Reason:
This happens when your storage space is getting filled up and you are in the process of downloading more items. It may be because you either have a few heavy files or apps, or because you haven't cleared your storage files in a long time.
Solution:
- Emptying your trash can to ensure deleted items have been removed from all locations on the computer.
- Your Downloads folder is yet another location that accumulates large files that are no longer necessary. The ones you need probably are even saved in other locations as well. You can free up a lot of storage space by deleting unnecessary files.
- Check your storage, About This Mac -> Storage. Here you can see what takes up most of your disk space. These could be photos and videos you no longer need. Delete as many as possible.
- You can locate large files on your Mac by:
・ In any folder in the Mac Finder, press Command+F.
・ Search 'This Mac'.
・ Your primary operator should be 'File Size' and the secondary operator should be 'is greater than'.
・ Select a file size. ( This way you can easily trace the redundant large files and delete them.)
・ Search 'This Mac'.
・ Your primary operator should be 'File Size' and the secondary operator should be 'is greater than'.
・ Select a file size. ( This way you can easily trace the redundant large files and delete them.)
- If the error message still appears, restart your Mac and recheck the disk space.
Message 2: 'The application * program name* is not open anymore'
Reason:
This is a bug seen even on recent models of the Mac and is a fairly common Mac error message that has troubled several users. Some attribute it to the RAM. The message implies that while the App may be open, it is unresponsive and in turn unusable for a while.
Solution:
Rebooting is a common remedy in this scenario. However, a simpler method is to stop the app, that is, quit it and then launch it again. There are two ways to do this:
- Simultaneously press the Command, Option, and Escape keys and target the app you want to Force Quit.
- If the app isn't available in the Force Quit menu, you can quit it by selecting it in the 'Activity Monitor'.
After 'Force quitting' the process, you can relaunch it. Generally, they resume their work without any further hassles.
Message 3: 'Safari Web content quit unexpectedly'
Reason:
This is a bug seen on even recent models of the Mac and is a fairly common Mac error message that has troubled several users. Some attribute it to the RAM. The message implies that while the App may be open, it is unresponsive and in turn unusable for a while.
Solution – a variety of quick fixes are in place to solve this issue:
- Free up cache data. To do this follow these steps:
・ Click Safari. Select Preferences and choose Advanced.
・ Select the 'Show Develop menu in menu bar' box.
・ In the Safari menu, click Develop then Empty Caches.
・ Select the 'Show Develop menu in menu bar' box.
・ In the Safari menu, click Develop then Empty Caches.
- Check for updates and make sure you are using the most recent version of Safari. An update must have been released that you accidentally overlooked. To check for updates, open the Mac App Store and select Updates.
- Clear History. History occupies a lot of RAM and in turn makes the app crash. You can clear history by going to History > Clear History.
This is a fairly popular error message and has many more solutions. The ones mentioned above are the few that are used widely.

Message 4: Enter password for your iCloud ID
Reason:
This common mac error message that occurs while the user is browsing is attributed to many factors. It could be due to cache memory overflow, or even due to add-one and extensions that help improve your internet experience.
Solution:
If you are suspicious of the dialogue box, scan your Mac for any malware. Otherwise, follow the steps below:
- In the Apple menu, select System Preferences.
- Choose iCloud and sign-in. If it appears that you've already signed-in, sign-out then sign-in once more.
This would make sure such error messages don't pop-up again.
Message 5: 'You can't open the application because it is not supported on this type of Mac'
Reason:
This common Mac error message is due to an outdated version of your OS. It also may occur because the version of the app and that of your Mac are not in sync.
Solution:
Update the program to its most recent version available on the Store. If this message appears despite the update, consider going back to an old edition of the Mac, so that the program and the computer are compatible.
Message 6: Mac displays a folder with a question mark
Reason:
This common Mac error message is due to an outdated version of your OS. It also may occur because the version of the app and that of your Mac are not in sync.
Solution:
While booting your Mac, press the Alt key. If the problem persists, you might have to use Recovery Partition and install an older version of the Mac OS.
Message 7: Mac OS X kernel panics
This is the least common Mac error message. This is also the scariest because it is rare and most people generally don't know how to tackle this. It occurs when the Operating System detects an error it can't fix.
Solution
You just need to press and hold the Power key till it switches off. Press the Power key again to turn on your computer. If such messages appear again, there may be some problem with the internal machinery of your laptop, like the RAM or the graphics card.
Conclusion
These issues may appear alarming the instant they occur but they are fairly simple to tackle. All you need is a little assistance from forums online and you're good to go. However, if any or all the above messages appear too often, it's time to surrender your Mac for a thorough check-up. There may even be a need to replace certain hardware.
Another common error message from Mac is that your files can't be found or no items match your search. To recover missing files, you can useRecoverit Data Recovery, the most reliable data rescue software.Recover lost files on Mac.

Get Setapp, a toolkit with fixes for all Mac problems
Mozilla's Firefox browser is known for its speed and a large collection of extensions that let you customize the experience to your heart's desire. But when Firefox is running slow, crashing, or not loading websites properly, it can be frustrating to figure out why. Follow our step-by-step guide to get your Firefox back to tip-top condition.
What are the most frequent problems with Firefox?
Overall, Firefox is a top-rated and highly reliable browser — good choice for both professional and everyday users. However, serving so many platforms on so many devices and screens, even the best of the best sometimes let us down. But worry not, in this how-to we've combined the most frequently occurring Firefox problems and written specific instructions on how to fix them.
Fix every Mac problem via Setapp
Get a curated set of Mac applications that fix Firefox — just like tons of other problems on your computer. Give it a try!
Quick navigation:
Why is Firefox so slow, hangs or keeps freezing?
Slow Firefox browsing experience is truthfully beyond annoying. It seems like it's almost working, but you can't get anything done.
Here we've listed some suggestions that should get your Firefox run faster.
1. Close inactive tabs
See how many tabs you have opened. More than a few? Active tabs mean active processes that take up your laptop's RAM and drastically slow down its capabilities. Just close the tabs you're not actively using. If they are important to remember, save them to bookmarks or stash them in a special 'Read Later' list in a to-do application such as 2Do.
2. Clear Firefox cookies and cache
All the websites you visit leave behind cached image files, which are supposed to speed up load times, and cookies, which can save you from having to log in over and over. Those are big conveniences if they work the way they're supposed to, but sometimes cache and cookies can cause glitches and slowdowns.
If Firefox is acting up, you can clear cookies and cache by doing the following:
- Click the Library button
- Choose History > Clear Recent History
- Change the time range to Everything
- Click the arrow next to the word Details
- Select Cache and Cookies
- Then click the Clear Now button
Alternatively, you can do this easier and safer with CleanMyMac. Just click Privacy in the sidebar and then choose Firefox from the list. Change the time range to Everything, and you can clear all of the cookies, browsing history, downloads history, tabs, saved passwords, and even autofill values.
3. Update Firefox and macOS
If closing tabs and clearing the cache didn't work, it's a good idea to update Firefox and macOS to its latest versions. When Firefox is active, just click on Firefox in the menu and select About Firefox. The latest available update should start downloading automatically. When it's ready, click Restart to Update Firefox and you are ready to go.
Updating macOS is easy too. Just launch the App Store on your Mac. Go to the Updates tab and wait till it shows you all the new software versions available. If you see new updates for macOS, click Update and follow the restart instructions.
4. See what consumes hardware resources
If the problem persists, check for high hardware resource usage. For basic information, you can use Mac's native Activity Monitor. However, to see the whole picture, get a pro-level app, such as iStat Menus. If you see Firefox using too much memory or CPU, you need to take some action.
Keep your Mac controlled with iStat Menus
Download a Mac app that cleverly monitors your CPU resources, battery, and anything that affects performance. Fix problems before they arise.
5. Troubleshoot plugins and extensions
When Firefox stops responding to your clicks it's very likely that one of your installed plugins is the culprit. To check for that, click the Menu button, and then choose Add-ons. In the Add-ons Manager's Plugins panel, you can select Never Activate for each plugin, then restart Firefox and see if the problem is still happening.
If the problem is gone, turn the plugins back on one by one, just changing that Never Activate option back to Always Activate. Restart Firefox each time and then try to recreate the error. Once the problem reappears, you'll know it was likely caused by the last plugin you re-enabled.
You can also remove a plugin with CleanMyMac's Extensions tab, which is actually a lot easier than using Firefox. In Firefox itself, you have to type about:plugins, then find the file path for that plugin and navigate to it in the Finder. Mozilla then recommends you change the filename to add an X in front, which will remove the plugin. You can reinstall a fresh copy of the plugin (from official sources only!), or just see if you can live without it.
To check your extensions in Firefox, go to about:add-ons, then click Extensions in the sidebar. You can disable extensions here, and then turn them back on one by one, in the same way you just checked your plugins. If you want to remove all your extensions and start fresh, you can click the Remove button or use the Extensions tab in CleanMyMac, which manages extensions, add-ons, and plugins from one place.
6. Stop loading Flash content
Preventing Flash content from loading automatically deserves a separate explanation. Some websites use way too much Flash content, and loading and playing all of that uses up your computer's resources, especially if you keep a lot of tabs open. Luckily, you can tell Firefox to stop loading Flash content by default, until you ask for it.
- Click the Menu button and select Add-ons, or select Tools > Add-ons from your Mac's menu bar. (Or press Command-Shift-A, or type about:add-ons into the URL bar. It all takes you to the same place.)
- In the Add-ons Manager, click Plugins in the sidebar, and then look for Shockwave Flash.
- Change the dropdown from Always Activate to Ask to Activate. After that, websites will display an Activate Adobe Flash button in place of Flash content, and all you have to do is click that to allow Flash to display it.
Following the tips above should eliminate 90% of your Firefox problems. But if you're still experiencing troubles, there is more you can do. Read on.
Avoid Firefox crashing
Get Setapp to fix Firefox crashing issues. No more freezing or showing errors while loading content.
Mozilla Firefox crashes unexpectedly or won't open
Whether Firefox shows you an error message every time you try to launch the app or right when you're in the middle of a working session, there is only one way to fix that — reinstall the application.
The easiest way to reinstall Firefox is to quit it, delete the Firefox file from your Applications folder, and download the new version from the official Mozilla website. That will uninstall the application but keep all your user data intact, and when you reinstall a new copy, you bookmarks and passwords will still be there.
But that's not the best way to do it, since Firefox leaves all kinds of data on your hard drive besides the main application file. A better way is to use an application that's able to delete all Firefox information completely or simply reset the app, such as CleanMyMac.
To reset the Firefox browser app on mac:
- Launch CleanMyMac
- Go to the Uninstaller tab
- Choose Firefox from the list
- Choose Application reset and click Uninstall round button
There are rare cases when the 'Firefox quit unexpectedly' message could be caused by the Mac security update. This happens when your Mac's firewall used to recognize previous versions of Firefox but no longer trusts the new one. Follow official Mozilla documentation to fix this issue.
Firefox shows errors loading websites
So your Firefox is fast and doesn't randomly quit, but still doesn't seem to load websites. There are a few things that might cause this, so let's zero in on the problem by gradually excluding various perpetrators.
1. Check your network connection
Turn your modem off and on (helps in nearly all cases). Check that your network connection is performing up to standards by using WiFi analyzers, such as NetSpot and WiFi Explorer. As soon as you launch NetSpot, make sure it's set to Discover mode, and it will scan all nearby WiFi networks automatically. WiFi Explorer is just as easy — launch the app and click the play button to analyze the network quality around you.
2. Launch websites in other browsers
If your WiFi network seems to be fine, it's good to check whether the connection works in other browsers, like Safari or Chrome, just to make sure that the problem in fact is with Firefox specifically. Then, check the settings in your firewall by following the steps outlined by Mozilla.
3. Fix the proxy server issue
If upon loading the website you get the 'Proxy server is refusing connections' message, there is an easy fix for that.

- Open Firefox > Menu > Options
- In the Options, click Advanced and then Network
- Choose Settings and then 'No proxy' and click OK
- Restart Firefox and the problem should be fixed
4. Validate the security certificate
In case Firefox shows you that it has troubles validating some website's security certificate, it might be related to improperly set date and time on your system. Just make sure your timezone settings in System Preferences > Data & Time are configured correctly and Firefox should go back to validating the website certificate normally.
5. Flush DNS cache
Another option you can try is flushing the DNS cache, which acts as a temporary database, storing all sorts of connectivity logs and website access attempts.
- Open up the Terminal utility
- Type sudo killall -HUP mDNSResponder;say DNS cache has been flushed
- Press Enter and type your admin password when prompted
- An alert a few moments later will inform you that the process is complete
Combine flushing the DNS cache with clearing out cache and cookies from Firefox, and restarting your Mac to get the best result.
6. Disable DNS prefetching
If you are still experiencing troubles loading websites, it could be that DNS prefetching is at play. Usually Firefox tries to speed up loading new websites by using DNS prefetching, but it can also cause loading errors with some system configurations. To disable DNS prefetching:
- In the address bar, type about:config and press Return. The about:config 'This might void your warranty!' warning page may appear. Click 'I accept the risk!' to continue.
- Hold down the Ctrl key while you click on the list of preferences. Select New and then select Boolean.
- In the 'Enter the preference name' field, enternetwork.dns.disablePrefetch and click OK.
- Select True when prompted to set the value and click OK.
7. Scan your Mac for malware
The last step to try to fix the website loading issue is to check your system for malware. T pain auto tune app download. If you remember Firefox being haunted by ad pop-ups, toolbars you didn't install yourself, or a new default home page, you might have picked up some malware that's hijacking your browser sessions.
A simple malware tool for Setapp users is CleanMyMac Malware Removal tool. It's a free download, with a pro license for more active, real-time protection. The free product will however scan your Mac and safely remove any malware at no cost to you.
Firefox doesn't work as it should
When your Firefox is just generally behaving incorrectly, a few more tips might come in handy. Start with restarting your Mac, and then clear the cache and troubleshoot your plugins as described above.
1. Restart Firefox in Safe Mode

2. Refresh Firefox

There is another clever feature inside Firefox that clears out your extensions and themes, plus resets all the preferences to default, but keeps your personal information intact, including bookmarks, history, open tabs and windows, saved passwords, autofill info, and even cookies.

- You'll find a lot of information about your browser installation, as well as a big friendly Refresh Firefox button at the top-right
- You can also get to Safe Mode this way, by clicking the button that says Restart with Add-ons Disabled
3. Create a new Firefox profile
For times, when neither options fixed the problem, try creating a fresh Firefox profile, which won't have any of your bookmarks, passwords, and user preferences, but might get rid of the problem.
- Open the Terminal utility
- Type in /Applications/Firefox.app/Contents/MacOS/firefox-bin -P
- Press Enter and the Profile Manager window should open
- Click Create Profile… then Next and enter the name for the profile
- Press Done
4. Turn off hardware acceleration
In cases when Safe Mode seemed to fix the problem but checking plugins didn't bring any result, the problem may hide in hardware acceleration, which is off by default in Safe Mode. Here's how to turn it off in the regular mode too:
- Open Firefox > Preferences
- In the General panel, scroll down to the Performance section and uncheck the box labeled 'Use recommended performance settings'
- Uncheck another box named 'Use hardware acceleration when available'
- Then quit and restart Firefox
