Wi-Fi problems on macOS Big Sur/Mojave/Catalina

Wi-Fi connection — it is central to intelligent life on Earth. But there could be numerous reasons your Mac won’t connect to Wi-Fi: a new software update, broken Wi-Fi preferences, or several networks conflicting with each other. Below we’ll explain what to do when you can’t connect to Wi-Fi or your connection is constantly dropping off.

Step 2: Run the setup and install the application.Once done, open DiskClean Pro. Step 3: On the home screen, you will notice a summarized System Status of your Mac.Now click on Start System Scan button. Step 4: As DiskClean Pro starts the scan, it will consider all the junk and redundant files.Now, go to One-Click Care feature given under the Junk Cleaning category. So, Find my Mac won't turn on unless there is a recovery partition. Remote wipe most likely won't work if the Recovery partition isn't bootable. To enable Find My Mac but disable Remote Wipe, you need to have a recovery partition, and it needs to not successfully boot.

Enable or disable macros in Office for Mac. This message appears regardless of whether the macro actually contains a virus. You can turn off the. If you were able to turn on Find My Mac, but received a warning that location services were turned off, then you will need to enable location services before your Mac can be located on a map in case it’s lost or stolen.

  • Mac connected to Wi-Fi, but no Internet access
  • Wi-Fi connection keeps turning off

Tip: In case your Mac is generally slow, which obviously affects the Internet too, you may start with fixing the performance issues first. The quickest is to delete junk and old caches from your drive and browsers.

Ways to fix Wi-Fi on Mac

Run the default Wi-Fi assistants

To troubleshoot Wi-Fi problems on Mac it’s good to start with native tools that came with your OS.


Go to Apple Menu -> System Preferences -> Network

This window lets you inspect your Wi-Fi preferences. If your Mac has internet connection problems, click Assist me as shown in the screenshot below. This will launch a built-in Diagnostics tool.

Did it solve the problem? Good news there’s another instrument provided by Apple, a Wireless Diagnostics app.
Option + click the Wi-Fi icon in the top right corner
Click Open Wireless Diagnostics…

Delete and reset Wi-Fi network settings

This step will reconfigure your existing Wi-Fi settings and launch your network experience from scratch. But before you begin, we seriously recommend to back your Mac up using Time Machine.

  1. Turn off Wi-Fi and close shut down your browsers
  2. Open Finder -> Go -> Go to Folder..
  3. Paste in the following line:

4. Select the files listed below (as shown in the screenshot)


5. Move these files to Trash (without deleting)
Or move them to a new folder on your Desktop.
6. Restart your Mac
Now you will have to revisit Wi-Fi preferences (Click Open Network Preferences under Wi-Fi icon). Turn Wi-Fi on and select your Wi-Fi network again.

The path above proved to be a good remedy in cases when Wi-Fi connection drops off after upgrading to macOS Catalina. If the issue persists, you may consider to clean install macOS Catalina.

Wi-Fi won't turn on after sleep mode on Mac


In some cases, sleep mode settings is the reason your Wi-Fi drops off on Mac and wouldn’t turn on again. Try this simple fix which many users found helpful:

Go to System Preferences -> Energy Saver
Disable Wake for Wi-Fi network option

Check your Wi-Fi now (cross your fingers). Did it do the trick? If not, let’s move on to the next step.

Flush DNS cache

Another way to fix Mac Wi-Fi not working is to flush your DNS cache. DNS service helps your Mac find IP-addresses, much like in a phone book. It has a cache folder of its own. Removing these cache files is helpful when your Wi-Fi slows down at random or you can’t access certain websites.

To save you from meddling with critical system folders, here’s a quick workaround.

1. Download DNS Flusher (it’s built into CleanMyMac X — get it here).
2. Go to Maintenance tab and tick Flush DNS cache

That’s all — and this solution is 100% free and takes no more than a minute.

By the way, CleanMyMac X is pretty much an indispensable tool if you want to keep your Mac clean and junk-free. It removes up to 74 GB of junk files on an average Mac, so give it a spin, just in case.

Reboot your Wi-Fi router

Plug off your router and leave it for a minute or two. This way you will know if your Mac won’t connect to Wi-Fi because of router issues. Plug your router back in and try to connect other Wi-Fi devices in the room.

Additionally, try placing your router in a different place. Your Wi-Fi signal could be lost due to neighboring network or it is catching a “dead-zone” in your house. If your room allows it, move it right in the center of the room. Fewer barriers, the better signal.

Still no Wi-Fi connection on Mac? Switch off the Bluetooth

Bluetooth devices often interfere with Wi-Fi, especially if the Wi-Fi signal is weak. It’s because both rely on radio frequencies to work. So one more idea to fix your Wi-Fi not working on Mac problem is to inspect the Bluetooth settings.

Try disconnecting the Bluetooth and see if the problem persists.

Go to Apple menu -> System Preferences
Select Bluetooth
Then click Turn Bluetooth off

Update your router firmware

If you are using Apple Airport router you’ll need Airport Utility to perform the update. Obviously, this step requires an internet connection. You can connect via cable if your Wi-Fi doesn’t work on Mac.
Go to Applications
Type Airport Utility in the search bar

You’ll see your Airport base station. If you see a red notification badge next to the base name, click it for more details. If the update is available, the app will show you the Update button.

Customize MTU and DNS settings to fix Wi-Fi on Mac

MTU stands for Maximum Transmission Unit and describes the packet size that is exchanged via the network (measured in bytes). The solution described below implies lowering MTU size which should make your WI-Fi connection less laggy. While customizing DNS location has also proved effective to solve even the most bitter Wi-Fi problems on Mac.

But don’t let these geeky terms put you off. The path takes just about a minute and you’ll be proud to have fixed your Mac Wi-Fi not working, the Apple Genius way.

Step 1.

Go to System Preferences -> Network
Select Wi-Fi in the left panel
See Location menu on top
Click Edit Locations…

Step 2.
Now create a new location by clicking [+] plus button. Name it anything you like. Click Done.

Step 3.

Then choose your standard Wi-Fi connection under Network Name
Click Advanced
Go to TCP/IP tab and click Renew DHCP lease .

Step 4.

Go to DNS tab and by clicking [+] buttons enter and as IP-addresses, each in a separate line. These two are Google’s alternative DNS servers that the company recommends using — they are safe. But before you do this, make sure to copy your current DNS address on a piece of paper.

Step 5.

Go to a Hardware tab from the previous step.
Under Configure dropdown menu select Manually
Click MTU and set the custom size of 1453
Click Apply

Well done. Your Mac Wi-Fi not working should have been resolved.

Still no or poor Wi-FI Connection on Mac?

Maybe all this time you’ve been digging in the wrong place as the problem is in your Mac itself. It might need some basic tidying up and maintenance to run faster. Try giving it a full clean with a tool like CleanMyMac X (it's my favorite among similar Mac tune-up apps — here's the official free download from the developer site). Hopefully, once your Mac is clean and up to speed again, your Wi-Fi should get back to norm.

May the Wi-Fi be with you. Thanks for reading.

Dark mode is savored by many. But I’m not a fan. And I’m pretty sure many others like me don’t like the black or dark mode. Fortunately, when an app or a tool introduces the dark mode, they give us the ability to disable it too. In this post, we will tell you how to get rid or turn off the dark mode in Microsoft Word, Excel, and PowerPoint on Windows and macOS.

The proper dark or black theme is limited to Office 365 subscribers only. On Windows, you get a lighter version of the black theme known as Dark Grey. It is available for all subscribers. The methods mentioned here let you disable the Grey theme too.

Let’s dive into the steps of disabling black theme on Microsoft Office apps.

Disable Dark Mode in Microsoft Office Apps on Windows

There are two methods to do so. While one removes dark mode or the black theme from all the connected PCs where you are signed in to your Microsoft account, the second one changes it on the current system only. However, in both methods, the dark mode will be disabled across all the Microsoft Office apps. Meaning, you cannot keep the dark mode active in Word and disable it in Excel. It will turn off in all the Office apps.

Here are the two methods.

1. Turn off Dark Mode Across All Computers

Turn Off Find My Mac

When you use this method to disable the black theme, it will reflect across all the devices where your Microsoft account is logged in. For instance, if you are using Word on two Windows PCs and you turn off black theme on one PC using the following steps, it will automatically change on the second PC too.

Here are the steps:

Step 1: Open any Microsoft Office app such as Word, Excel, etc.

Step 2: If you created a new file, click on Account present in the left pane.

If you opened an existing file, click on File at the top. Scroll down and click on Account.

Step 3: Click on the drop-down box present under Office Theme. Select either Classic or Colorful to remove the dark mode from all the Office apps on your Windows PC.

2. Turn off Dark Mode on One PC

If you want to change the black theme on only your PC, i.e., not on all the PCs where your Microsoft Office account is synced, then there is an option to do that as well. Let’s check how to do it.

Step 1: Launch any Microsoft Office app on your system. Let's say Word.

Step 2: Click on File at the top and select Options from it.

Step 3: Scroll down in the General tab. Click on the drop-down box next to Office Theme. Select Classic or Colorful. Click on Ok at the bottom to save the changes.

Note: The dark theme will be deactivated on the current PC only.

Disable Dark Mode in Microsoft Office Apps on macOS

You get two methods to deactivate the dark or black theme in macOS too.

1. Turn off Dark Mode Across All Office Apps

If you are using Office 365 or 2019 and you have set your macOS to dark mode, then the same will apply to Microsoft Office apps. So you can disable the system dark theme to remove it from Office apps such as Word, Excel, and more. Again, the dark mode will be removed from all the Office apps and not just one.

Let’s see how to do that.

Step 1: Click on the Apple menu at the top and choose System Preferences from it.

Step 2: Click on General.

Step 3: If Dark is selected, click on Light to enable it. By doing so, the dark mode will be turned off for Office apps, including other supported apps on your Mac.

Choosing Auto will automatically disable dark mode in the morning. It’s available on macOS Catalina and above. Find out more about how to disable dark mode on macOS.

2. Disable Dark Mode on Individual Office Apps

The above method will turn off the dark theme on all the Office apps. In case you want to change it on only one app, then use this method.

Here are the steps:

Step 1: Open the Office app for which you want to disable the dark theme. For instance, we want to turn it off on Word. What is the latest os x version.

Then, open Word and click on the Word menu at the top and select Preferences from it.

Step 2: Go to the General tab.

Step 3: Look for Personalize. Check the box next to Turn off Dark Mode.

That will disable dark theme on Word. Now, if you want to disable it on PowerPoint or Excel, you will have to repeat the above steps in their apps.
