Why does my Mac freeze and how do I fix it?

Imagine this frustrating scenario: you’re in the middle of a crucial task on your Mac, and, suddenly, everything comes to a halt. You can’t click anything, and your screen is frozen.

This can be a nightmare for anyone using a Mac desktop or a MacBook laptop. 

Let’s explore the causes of a frozen Mac and provide quick solutions to restore its functionality. If you have a PC and it is freezing up, check out these steps to fix the issue by clicking here.

4 reasons that can cause a Mac to freeze?

1. A hung application consuming excessive memory or CPU resources

2. Newly installed extension or driver that causes a compatibility issue with MacOS

3. Faulty keyboard, mouse or other external device

4. Malware infection leading to increased CPU and memory load.

How to fix a frozen mac

Tip 1 — Force-quit applications

If an application freezes, it may only be temporary. Wait a minute or two to see if your Mac stays locked up. If it does, you might need to force-quit the frozen application.

To force-quit an application, use this key command: Command + Option + Escape. This will open the Force Quit menu. Alternatively, right-click the app’s Dock icon and select Force Quit from the menu.

Tip 2 — Restart your Mac

If force-quitting doesn’t work, restart your Mac. If you can move your mouse pointer, click on the Apple Menu in the top-left corner and select Restart.

If you are unable to control the pointer, there are still a couple of other things you can do:

  • If  you have an older Mac desktop or MacBook that has a DVD drive, press Cmd + Ctrl + Eject
  • If you have a newer Mac that has a Touch ID, press Cmd + Ctrl + Option + Power Button
  • If you have a newer Mac and the steps above don’t work, you will need to press and hold the power button to force-turn off the Mac.

Tip 3 — Free up RAM

Being low on RAM can also cause a frozen Mac. Random Access Memory, or RAM, is the memory that your Mac uses to run applications and handle active tasks. When you open an application, load a file or perform any task, it is loaded into your Mac’s RAM for quick access.

If your Mac doesn’t have enough RAM to handle all the active processes, it starts using virtual memory, which is a portion of your hard drive that acts as temporary RAM. Virtual memory is significantly slower than using actual RAM because it takes more time to read data from the hard drive. Here are a few easy ways to free up RAM on your Mac:

  • Quit applications you’re not actively using as they consume RAM even when running in the background.
  • Ensure your Mac’s operating system and applications are up to date. Newer versions often include performance improvements and bug fixes.

Remove applications you no longer use to free up RAM and storage space.

Tip 4 — Disconnect external devices

Sometimes, some peripherals cause your Mac to freeze. To check if that is the case, shut down your Mac and disconnect all external devices — keyboards, mice, external monitors, etc. Now, press the power button to restart your Mac and see if it is still frozen.

Tip 5 — Uninstall unresponsive apps

If a specific app is consistently causing your Mac to freeze, consider uninstalling it.

Tip 6 — Update your software

Sometimes, your Mac can freeze up due to a software bug in an older version of MacOS. It’s always important to keep MacOS updated because Apple routinely rolls out software improvements to help your Mac run smoothly.

Here’s how to make sure you’re running the latest version of macOS:

  • Click on the Apple Menu in the top left corner and click on System Settings

Tip 7 — Restart in safe mode

If your Mac is freezing due to a broken extension, you can spot it by booting into safe mode. This special boot loads only those files essential to macOS and performs some troubleshooting. If your Mac isn’t having the same issue when booting into safe mode, then it probably means the problem is with an app or extension.

Booting in safe mode differs depending on which generation of Mac you have. If you have an Intel-based Mac (2020 or earlier), follow these steps:

  • Shut down your Mac and wait 10 seconds
  • Restart your Mac and hold the shift key
  • Release the shift key once the login window appear

If you have a newer Mac that runs on Apple’s silicon (2021 or later), follow these steps to restart in safe mode:

  • Shut down your Mac and wait 10 seconds.
  • Press and hold the power button until the startup options window appears
  • Select a startup disk.
  • Press the Shift key and click Continue in Safe Mode.
  • Release the Shift key.

Kurt’s key takeaways

There’s no need to panic if your Mac freezes. Follow these eight tips, and you should have your Mac back up and running in no time. Always keep your Mac current, and don’t forget to delete old applications or extensions you don’t use anymore. It’s pretty easy to overlook — I know I do sometimes — but it can free up space on your Mac and keep everything running smoothly.

Meta is stopping teens from chatting with its AI characters

Meta is stopping teens from chatting with its AI characters

Meta is “temporarily pausing” the ability for teens to chat with its AI characters as it develops a “new version” of the characters that will offer a “better experience.” The company made the announcement in an update to a blog post from October where the company had detailed more parental controls for teen AI use. The change blocking teens from accessing the characters will go into effect “starting in the coming weeks.”

”Since we announced our plans to build parental controls for AI characters in October, we started developing a new iteration of AI characters generally (i.e. for both adults and teens),” spokesperson Sophie Vogel tells The Verge. “Rather than building the parental controls twice (for the current AI characters and the new iteration of AI characters) we’re pausing teen access to the current version while we focus on the new iteration. When that new iteration is available for teens, it will come with parental controls.”

According to TechCrunch, “Meta said that it heard from parents that they wanted more insights and control over their teens’ interactions with AI characters, which is why it decided to make these changes.”

In October, Meta announced that parents would be able to block their teens’ access to one-on-one conversations with its AI characters, block their teens from talking with specific AI characters, and share insights with parents on the topics their teens discuss with Meta’s AI characters and its AI assistant. The original plan was to roll out those controls early this year.

Last year, also in October, Meta changed Instagram teen accounts to allow teens to be able to see content that’s reflective of what might be shown in a movie rated for people that are 13 or older.

Ransomware attack exposes Social Security numbers at major gas station chain

Ransomware attack exposes Social Security numbers at major gas station chain

NEWYou can now listen to Fox News articles!

Cybercriminals are happy to target almost any industry where data can be stolen. In many cases, less prepared and less security-focused companies are simply easier targets. 

A recent ransomware attack on a company tied to dozens of gas stations across Texas shows exactly how this plays out. The incident exposed highly sensitive personal data, including Social Security numbers and driver’s license details, belonging to hundreds of thousands of people. 

The breach went undetected for days, giving attackers ample time to move through internal systems and steal sensitive data. If you’ve ever paid at the pump or shopped inside one of these convenience stores, this is the kind of incident that should make you stop and pay attention.

What happened in the Gulshan ransomware attack

According to a disclosure filed with the Maine Attorney General’s Office, Gulshan Management Services, Inc. reported a cybersecurity incident that impacted more than 377,000 individuals. Gulshan is linked to Gulshan Enterprises, which operates around 150 Handi Plus and Handi Stop gas stations and convenience stores across Texas.

WINDOWS 10 USERS FACE RANSOMWARE NIGHTMARE AS MICROSOFT SUPPORT ENDS IN 2025 WORLDWIDE

The company says it detected unauthorized access to its IT systems in late September. Investigators later determined that attackers had been inside the network for roughly ten days before anyone noticed. The intrusion began with a phishing attack, a reminder of how a single deceptive email can still open the door to massive breaches.

Ransomware attacks don’t just hit tech companies. Retailers like gas stations store sensitive customer and employee data that criminals actively target. (Kurt “CyberGuy” Knutsson)

During that window, the attackers accessed and stole personal data, then deployed ransomware that encrypted files across Gulshan’s systems. The compromised information includes names, contact details, Social Security numbers and driver’s license numbers. That combination is especially dangerous, since it can be used for identity theft, account takeovers and fraud that may surface months or even years later.

Why the lack of a ransomware claim still matters

So far, no known ransomware group has publicly taken credit for the attack. That might sound like good news, but it does not necessarily change the risk for affected individuals. In many ransomware cases, silence can mean one of two things. Either the attackers have not yet posted stolen data publicly, or the victim company may have resolved the incident privately.

Gulshan’s filing states that it restored its systems using known-safe backups. That detail often suggests a company chose to rebuild rather than negotiate with attackers. Even so, once data has been copied out of a network, there is no way to pull it back. Whether or not the stolen information ever appears online, the exposure alone puts affected people at long-term risk.

This incident also highlights a recurring pattern. Retail and service businesses handle huge volumes of personal data but often rely on legacy systems and frontline employees who are prime phishing targets. Gas stations may not feel like obvious hacking targets, but their payment systems, loyalty programs and HR databases make them valuable all the same.

We reached out to Gulshan Management Services for comment regarding the breach, but did not receive a response before our deadline.

10 steps you can take to protect yourself after a breach like this

If your information was exposed in this breach or any similar ransomware incident, there are concrete steps you can take to reduce the fallout.

1) Monitor your credit and identity closely

If the company offers free credit monitoring or identity protection, enroll in it. These services can alert you early if someone tries to open accounts or misuse your identity. If nothing is offered, consider signing up for a reputable identity theft protection service on your own.

Identity Theft companies can monitor personal information like your Social Security Number (SSN), phone number, and email address and alert you if it is being sold on the dark web or being used to open an account. They can also assist you in freezing your bank and credit card accounts to prevent further unauthorized use by criminals.

See my tips and best picks on how to protect yourself from identity theft at Cyberguy.com.

2) Consider a personal data removal service

The less of your information that’s floating around data broker sites, the harder it is for criminals to target you. Data removal services can help reduce your digital footprint over time.

While no service can guarantee the complete removal of your data from the internet, a data removal service is really a smart choice. They aren’t cheap, and neither is your privacy. These services do all the work for you by actively monitoring and systematically erasing your personal information from hundreds of websites. It’s what gives me peace of mind and has proven to be the most effective way to erase your personal data from the internet. By limiting the information available, you reduce the risk of scammers cross-referencing data from breaches with information they might find on the dark web, making it harder for them to target you.

Even when no ransomware group claims responsibility, stolen data can still fuel identity theft, fraud, and account takeovers long after a breach occurs. (Kurt “CyberGuy” Knutsson)

3) Use a password manager

A password manager helps you create and store unique passwords for every account. If attackers try to reuse stolen data to break into your online accounts, strong, unique passwords can stop that attempt cold.

Next, see if your email has been exposed in past breaches. Our No. 1 password manager pick includes a built-in breach scanner that checks whether your email address or passwords have appeared in known leaks. If you discover a match, immediately change any reused passwords and secure those accounts with new, unique credentials.

4) Turn on two-factor authentication (2FA) everywhere possible

2FA adds an extra barrier, even if someone has your personal details. Prioritize email, banking, cloud storage, and shopping accounts, since those are often targeted first.

5) Install and keep a strong antivirus software running

Strong antivirus software can help detect phishing attempts, malicious downloads, and suspicious activity before it turns into a full compromise. Keep real-time protection enabled and don’t ignore warnings.

The best way to safeguard yourself from malicious links that install malware, potentially accessing your private information, is to have strong antivirus software installed on all your devices. This protection can also alert you to phishing emails and ransomware scams, keeping your personal information and digital assets safe.

6) Watch for phishing and follow-up scams

After breaches like this, scammers often send fake emails or texts pretending to be the affected company or a credit monitoring service. Slow down, verify messages independently, and never click links you weren’t expecting.

7) Review your credit reports regularly

Check your reports from all major credit bureaus for unfamiliar accounts or inquiries. You’re entitled to free reports, and catching issues early makes them much easier to fix.

8) Freeze your credit to stop new accounts from being opened

If criminals expose your Social Security number, place a credit freeze as soon as possible. A credit freeze blocks lenders from opening new accounts in your name, even when thieves have your personal details. The credit bureaus offer freezes for free, and you can temporarily lift one when you apply for credit yourself. This step stops identity theft before it starts, instead of alerting you after the damage is done. If you prefer not to freeze your credit, place a fraud alert instead. A fraud alert tells lenders to verify your identity before approving credit, which adds another layer of protection.

9) Protect yourself from tax refund fraud with an IRS Identity Protection PIN

When Social Security numbers are stolen, tax fraud often follows. Criminals can file fake tax returns in your name to steal refunds before you ever submit your paperwork. An IRS Identity Protection PIN (IP PIN) helps prevent this by ensuring only you can file a tax return using your SSN. It’s a simple but powerful safeguard that can block a common form of identity theft tied to data breaches.

10) Lock down existing bank and financial accounts

Don’t just watch for new fraud, proactively secure the accounts you already have. Enable alerts on bank and credit card accounts for large transactions, new payees, or changes to contact information. If your SSN or driver’s license number was exposed, consider calling your bank to ask about additional protections or account notes. Acting early can prevent small issues from becoming major financial problems.

Kurt’s key takeaway

Your personal data doesn’t just live with banks and hospitals. Retailers, gas stations, and convenience store operators also hold information that can cause real harm if it falls into the wrong hands. When attackers get in through something as simple as a phishing email and stay undetected for days, the damage can spread fast. You can’t prevent these breaches yourself, but you can limit how much power stolen data gives criminals by locking down your accounts and staying alert.
