Make your Mac invincible
When Wi-Fi stops working on a Mac, it can be a nightmare. All of a sudden, you can’t make progress or even start on something without an internet connection.
Most of us take the always-on Wi-Fi connectivity for granted. Even when traveling thousands of miles from home in developing countries, most businesses, homes, and even public spaces are equipped with modems that broadcast wireless internet.
How to fix Mac won't connect to Wi-Fi
In many respects, Wi-Fi has become a commodity, a necessity for the smooth functioning of business, academia, governments, and the media. Thanks to Wi-Fi, we are more connected than ever before. Our music, emails, and even shopping are dependent upon it.
So if you’ve ever had Wi-Fi connectivity issues on a Mac, you might want to save this article for offline reading, just in case. There are a few ways to these problems.
1. Check your macOS
When Mac users update their operating system, Wi-Fi connectivity can vanish.
At the time of the original version of Catalina, a lot of users found they couldn't connect to Wi-Fi, which made it harder for Apple to release an update that included a patch solving this particular problem. In some cases, users had to download the updated version using a phone as a Personal Hotspot, which caused other problems, such as extra data costs.
Unfortunately, as a result of the recent macOS Big Sur release, some users were experiencing the same problem. You can find step-by-step instructions on how to fix Big Sur Wi-Fi problem (as well as other issues) here.
Turn Wi-Fi on and off
One way to fix this is to switch your Wi-Fi off and back on again. At the same time, it may also be worth changing the name of your home (or office) network and setting a new password, which you can do through your internet provider. If necessary, you should be able to do this through a mobile phone, and then check whether your Mac will connect again.
2. Wi-Fi signal issues
Sometimes it’s Wi-Fi signal causing all the problems. If that’s what you’re suspecting, here are the possible solutions:
Run a speed test and get a better signal
A good way to work out whether the problem is the Mac or Wi-Fi itself is using an analyzer app. To analyze your Wi-Fi network signal strength, use WiFi Explorer or NetSpot.
You may find that furniture and walls in your place are blocking or reducing the signal. When you are checking the results, it might be helpful to move your wireless router to a better location or ask if your broadband provider can install a signal booster.
Make WiFi faster on Mac
Download Setapp to declutter your Mac and make WiFi powerful. There's at least one tool that handles the task perfectly.
Don’t trust public networks
Ensure your personal information is securely protected on public Wi-Fi. While every public network can potentially “read” the data you send and receive, dealing with sensitive information on a public network is a huge risk. To stay safe, control your network connection with Activity Monitor or iStat Menus— perfect for real-time tracking of what’s being sent and received via network.
To prevent suspicious apps from accessing your data, use TripMode. The app allows to activate blocking right from your menu bar. So it’s a one-switch solution that you can use every time your Mac connects to a public network.
Secure your private network
Using your own network is certainly more secure than accessing public ones. But it’s never a risk-free deal. Private or public, there are a few tips that will help you stay safe:
Change the SSID name so that it’s hard to identify the type of router you use.
Solidify encryption. There are several options for Wi-Fi protection, out of which WPA2 is considered one of the most secure.
Use a VPN client. A reliable VPN app like Shimo will help you handle and place restrictions on the network you use. Plus, it has a module for setting multiple connections.
3. Forget your Wi-Fi network
Sometimes you need to let go to reconnect again. That also works for Wi-Fi signals.
Assuming you’ve already tried rebooting your Mac and router, disconnecting entirely is a tried-and-tested solution.
Here are the steps for doing this slightly trickier fix:
- Turn off Airport
- Go to Systems Preferences
- Network > Select Wi-Fi
- Click Advanced
- Select the network you want to disconnect from and click on minus, then agree.
Do that on any other device you can’t connect with, and then start the process to connect to that network, entering the password, and (fingers crossed) you should be connected again.
4. Declutter your Mac
One of the other problems that could be causing connectivity issues is bloat, junk, and clutter. Over time, Macs can get full of things they really don't need to store, such as cache files, email downloads, browser extensions and viruses. All of these slow down and overheat Macs, which could impact your connectivity as well.
Then, use CleanMyMac to clean up your macOS. This app is an effective solution and much-needed antidote to slow Mac performance. You can use it to dig up junk cluttering up Macs, delete unused apps completely, tidy up email folders and attachments, and remove plugins you don't need.
So if you’re wondering how to fix Wi-Fi and you’ve already tried every network-related strategy, it’s probably your Mac’s fault. CleanMyMac X will clear caches, browser extensions, and declutter disks and hard drives so that your Mac is operating at peak performance again. It also includes health monitors, so you can avoid similar issues in the future. Dive into Extensions, Uninstaller, and System Junk modules to clear away whatever can hinder your network connection.
5. Contact your broadband provider
Your broadband provider should have a speed testing function within wireless routers or your customer account portal. Increasing the speed, or switching to a faster provider, could be the solution to Wi-Fi connectivity problems, providing you’ve tried everything else first.
Prepare beforehand
Given you’ve already saved this article for offline reading, it might also be a good idea to download all the apps mentioned above, so you don’t have to use your phone’s data when the Wi-Fi crisis hit, which, hopefully, it never will.
Meantime, prepare for all the awesome things you can do with Setapp.

How to troubleshoot the Safari can't establish a secure connection to server issue?
After browsing the Internet for some time, the Safari browser might stop loading certain websites. We receive many reports from Mac users stating that they encounter the 'a secure connection could not be established' error message when using Safari and Chrome Internet browsers. Experienced Mac users often attempt to solve the issue, but are unsuccessful. Cleaning browsing data, cache, permissions, and resetting network settings usually resolves various browser related issues, but these methods do not eliminate the 'a secure connection could not be established' error message.
For everyday users and experienced Mac users alike, this problem can be frustrating, but fortunately, having analysed users' reports and suggestions, we have a number of solutions. Note that there might be several causes of this error message. The easiest way to find a solution is to try all methods mentioned in this guide - these should eliminate the 'a secure connection could not be established' error message.

Manage your DNS settings
DNS server entries might cause this problem. Google suggests that you to use their 'open entries' to ensure your connection is secure. To manage DNS settings, open System Preferences and choose Network. Click the Advanced button and select the DNS tab, remove all existing entries by selecting them and clicking minus(-). Then click the add (+) button and type 8.8.8.8, repeat the process and type 8.8.4.4. Restart the browser and check if the problem is solved.
Weak website's encryption
Apple has improved protection of their products, and as a result, block websites that contain weak encryption (websites that do not apply safety certificates that approve a webpage's encryption). Also, Safari might block a server if it detects that the connection route is through any proxy servers. Security improvements appeared with OS version 10.10.4 and iOS version 8.4 - from these versions, Safari began to block weak encryption websites. If your issue is caused by a missing or incorrect certificates problem, attempt to open the website through another browser such as Mozilla FireFox or Google Chrome. Quite often, Facebook and Twitter are interpreted as threats. Once the alternative browser loads the website, you will see a small green lock next to the URL address. Click the lock, and in the new pop-up window, click the more information button. In the new window, select the security tab, which is last option at the bottom. Under the security tab, click the show certificate button, and then switch tab to Details, which is at the top of the new pop-up window.
In the window, you will find all information required, including the title of the company providing the certificate. The next step is to run Keychain on the Mac. Use Spotlight by clicking the keyboard shortcut, Command and Spacebar. Then type Keychain. You can also go to the Utilities folder, which is under Applications through Finder. Here, you will find the Keychain application.
Once the app has launched, select the system roots to see a list of all certificates. Search for the one being blocked by Safari, double click it, expand the Trust option, and select System's defaults. Changing this option usually solves the certificate problems caused by a locked mail server. This also prevents other websites attempting to use this particular server.
Adjust your Antivirus Web Shield feature
Anti-virus software is developed to protect our computers and content from all possible threats. Since it is an automatic process, small mistakes and mismatches might be flagged as suspicious. Developers includes a feature called Web Shield that blocks suspicious websites without indicating what caused the blocked content. So users are often frustrated by unknown issues. If the methods listed above did not solve the issue, check your anti-virus software and if there is a Web Shield feature enabled, try to disable it and relaunch Safari. Check if the problem is resolved. The method to disable the Web Shield feature will depend on the software you are using.
Try disabling IPv6
Additionally, if none of the above steps solve the problem, there is one final option to try. If possible, attempt to use another Wi-Fi network and check if you are able to visit same pages without any restrictions. If all websites load correctly, try to disable IPv6 on the router (if it provides this option). Then, open Mac System Preferences and choose Network. Select your network and click Advanced. Select the TCP/IP tab. In the drop-down menu beside Configure IPv6, select Manually. In the case where Safari cannot establish a secure connection, this should solve the issue.
