Tip 1 — Give your Mac a restart
Before we do anything else, I suggest you restart your Mac first, especially if you prefer to leave your Mac in sleep mode instead of shutting the device down fully. You will want to shut down your Mac or MacBook regularly because of how MacOS stores RAM. The longer you leave a Mac on, the more RAM the computer uses as virtual memory, making the machine slower. However, restarting your Mac will reset your RAM and result in a refreshed Mac that runs faster. You can do this by clicking on the Apple icon in the upper left toolbar and then selecting Restart or Shut Down.

Tip 2 — Find and close power-hungry applications
One of the easier ways to speed up your Mac’s performance is to find and close power-hungry applications that you don’t currently need running in the background. To do this, you will open a program that is pre-installed on all Macs called Activity Monitor.
You can find the Activity Monitor by pressing Command + Spacebar and searching for Activity Monitor.
At the top of Activity Monitor, you’ll see tabs for different tabs for CPU, Memory, Energy, Disk and Network. Select the CPU tab, and you’ll be able to see what has been using the most CPU resources and end any applications that you don’t currently need. You don’t need to pay too much attention to the other tabs, but if you want, we suggest sorting by memory usage.
To close any application from the Activity Monitor, simply select and double-click on the application you want to close and press where it says quit.

Tip 3 — Update your operating system and applications
You’ll want to make sure you are performing routine software updates for MacOS, as well as routine updating for all the apps installed on your Mac:
Navigate to the Apple logo (top left corner of the screen) > System Settings > General tab (left column). From there, you can see any updates that are required for MacOS.

If you have any MacOS updates available, consider installing them now. If the operating system has been out for over three to four months, the hope is that Apple developers have addressed any bugs that have caused problems. After any big new operating system update, I usually like to wait a bit and search online to see if others have experienced any issues. Sometimes you won’t be presented with the latest operating system because your Mac computer is too old. If that’s the case, it may be time to start considering a new laptop or desktop computer.
You can also easily update applications from the App Store by navigating to the App Store. In your left column, you should have a section titled Updates, which will show you if you have any applications from the store that need updating.

Tip 4 — Free up storage space
Your performance will be negatively affected when you’re running low on storage. If you are using iCloud and have it synced across all devices, photos and text messages from your iPhone will end up being stored on your Mac, eating up space. Until you get more space, it might be helpful to turn off iCloud on your Mac.
A wide range of applications, such as Google Drive and Dropbox, can be used to back up files and photos to the cloud without storing them on your Mac. Music downloads can also take up a large amount of system storage on your Mac.
You can save a large amount of storage by not storing music directly on your Mac’s hard drive. Services like Apple Music allow you to move all of your music into the cloud and delete music from your hard drive but have it synced across all of your Apple devices before deleting anything.

Tip 5 — Use a quality performance optimization program
You’ll also want to have a quality performance optimization program. These programs are designed to do a deep cleanup of all that redundant junk from your device so that it can perform the way it’s supposed to and serve your needs. Here are my top picks for the best performance optimization programs in the industry.
Before you clean out your computer with these programs, it’s always a good idea to back up your devices.
Tip 6 — Empty the trash
One of the easiest and quickest ways to give your Mac a bit of a boost is to keep the trashcan empty. It’s a solid idea to go through your documents and files from time to time and delete documents you no longer use.
One place where unused files can build up is in your Downloads folder. To check your downloads folder:
- Open the Finder (icon that looks like a face in your dock) > Click Downloads
Here, you’ll have access to any files or documents that you have downloaded. You can delete them by highlighting, left-clicking and using the ‘Move to Trash’ option.
It’s important to remember that your unused files aren’t off your hard drive just yet.
- Locate the Trashcan Icon in your dock bar on your desktop.
- Delete all files in your trash by clicking the Empty button in the top right corner.

Tip 7 — Turn off visual effects
While Apple computers can handle MacOS easily, if your Mac is older than five years, it might struggle to keep up with the latest updates. If you feel that your Mac is under a lot of strain, you can take some of the pressure off by turning off what is known as Reduce Motion. By disabling motion effects, you can make your Mac feel more responsive. Animations, while visually appealing, can consume system resources and slow down older Macs. Here’s how to enable Reduce Motion.
- Click the Apple icon in the upper left of your Mac
- Choose System Settings
- Select Accessibility
- Next, choose Display
- Locate and toggle on Reduce Motion, so it turns blue, to disable most animations in MacOS

Tip 8 — Perform a clean install of MacOS
If you have followed these steps but still don’t feel an increased performance, you could wipe your hard drive and perform a clean install of MacOS.
This should only be done as a last resort. If you decide to format your Mac and re-install MacOS, back everything up beforehand. If a clean install doesn’t give you a better performance, you may need to consider investing in a new Mac.
Here’s how to know when it is time to replace your Mac.
Finally, as a reminder, you can always book a free online session with the Apple Store for any further guidance.
Kurt’s key takeaways
I hope these tips help you to get the most out of an aging Mac desktop or MacBook laptop. I always used to leave my MacBook in sleep mode, but once I started restarting it daily, I noticed an immediate increase in my Mac’s performance.
This is a great habit to get into even if you just bought a new Mac or MacBook, as it doesn’t apply to just older Macs. Remember, while a clean install of MacOS might be the most fool-proof way to increase the performance of an older Mac, you need to back everything up beforehand. I recommend backing up anything important to an external drive every few months, just in case.

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.
Update, January 23rd: Added information from a Meta spokesperson.

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.
To learn more about how to do this, go to Cyberguy.com and search “How to freeze your credit.”

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.
