8 tips to speed up your Mac’s performance; yes, really
If you’ve had a Mac computer for a few years, you might be looking for a way to speed up your performance without investing a large chunk of cash to buy a new Mac.
Luckily, today, we will teach you how to give your Mac a needed tune-up so that you don’t have to invest in a new machine just yet.
Remember, Mac computers are some of the best on the market, and even as they age, a little bit of maintenance will go a long way in keeping everything running smoothly. Here are eight tips to improve the performance of your Mac.

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.

Microsoft is disabling Office 2019 for Mac next month
Microsoft’s Office 2019 apps for Mac will stop working next month, because the company isn’t renewing a certificate that validates Office licenses. Owners of Office 2019 for Mac are being warned they’ll have to purchase Office 2024 or a Microsoft 365 subscription if they want to continue editing documents.
Microsoft previously promised that “all your Office 2019 apps will continue to function,” when it announced end of support in 2023. The company then quietly updated that support note last month to remove the mention of apps continuing to function, replacing it with “Rest assured that all your Office 2019 apps won’t lose any data.”
Starting on July 13th, Office 2019 for Mac and Office 2021 for Mac will both run in “reduced functionality mode,” allowing people to open files but not edit, save, or create new documents. The reduced functionality will impact Word, Excel, PowerPoint, Outlook, and OneNote.
While Microsoft is providing a certificate update for Office 2021 as it’s still supported until October 13th, 2026, the company is leaving Office 2019 for Mac users out in the cold as support for these apps ended a few years ago. “Office 2019 for Mac reached end of support on October 10, 2023, and no longer receives updates,” says Microsoft. “Because Office 2019 cannot be updated to the required version, this issue cannot be resolved by updating or reinstalling Office 2019 for Mac.”
JimmyTech points out that old versions of Microsoft 365 apps on Mac and iOS will also be affected by this certificate issue, but a simple update will fix it for those users.
Microsoft regularly ends support of software and there’s always the risk you could run into issues running older apps or versions of Windows. It’s still surprising to not see Microsoft make an exception here though, particularly because this certificate issue breaks the main functionality of an app you’ve paid a one-time license fee for.

Android fake call detection warns you about scams
NEWYou can now listen to Fox News articles!
You know that little moment when your phone rings and the name on the screen makes you drop everything?
Maybe it says your spouse, your daughter, your boss or your best friend. You answer because you trust the name. Then the voice sounds familiar too.
That is exactly what makes the latest phone scams so dangerous.
Android’s fake call detection can warn you when a caller may be pretending to be someone saved in your contacts. (Silas Stein/Picture Alliance)
Scammers no longer have to call from a strange number. They can spoof a trusted contact’s phone number. Then they can use AI voice tools to sound like someone you know. Android is now rolling out a new feature called fake call detection to help warn you when that familiar call may be a fake.

What is Android fake call detection?
Android fake call detection is a new protection built into Phone by Google. It is designed to spot suspected spoofed calls when both people on the call use Phone by Google.
Think of it as your phone quietly asking, “Is this call really coming from that person’s device?” If the answer looks suspicious, your phone can show a warning and advise you to hang up. That small alert could stop a scam before fear, panic or confusion takes over.
ANDROID SECURITY UPGRADES OUTSMART SCAMS AND PROTECT YOUR PRIVACY
How Android fake call detection works
The feature works automatically in the background. You do not need to answer a quiz, scan a code or press a button during the call. When a trusted contact calls you, their phone sends a silent confirmation signal to your phone. That signal helps prove the call really came from their device.
If a scammer spoofs your contact’s number, that confirmation signal may be missing. Your phone then checks with your contact’s actual device. If the real device says it is not placing a call, your screen can warn you that the call may be fake.
The system uses end-to-end encrypted RCS technology, so the check happens privately. You can also turn the feature off in Phone by Google settings.
AI DEEPFAKE ROMANCE SCAM STEALS WOMAN’S HOME AND LIFE SAVINGS
Why fake calls are getting harder to spot
For years, caller ID gave people a sense of control. If the name looked familiar, most of us felt safer picking up. That old habit now works in the scammer’s favor.
Scammers can use internet-based calling tools to spoof numbers. That means your phone may display the name of someone you trust, even though the call comes from somewhere else.
Then comes the AI voice trick. With today’s audio tools, scammers can make a fake voice sound shockingly real. They may pretend to be a family member in trouble, a bank employee warning about fraud or a manager asking for urgent help.
SCAMMERS EXPLOITED MOM’S FEARS TO STEAL HER ENTIRE LIFE’S SAVINGS
That combination makes the call feel personal and immediate. It also makes you more likely to act before you think.
Why Android is adding this protection now
Impersonation scams have become a major global problem. INTERPOL’s March 2026 Global Financial Fraud Threat Assessment cited impersonation fraud as one of the leading contributors to more than $400 billion in global losses.
In the U.S., impersonation scams remain one of the top fraud categories reported to the FTC. Losses reached $2.95 billion in 2024.
GLOBAL SCAM CRACKDOWN LEADS TO 276 ARRESTS
Those numbers tell you why this feature deserves attention. Scammers go where the money is. Right now, they know trusted voices and trusted names can open the door.
Which Android phones get fake call detection?
Google says fake call detection is rolling out globally in Phone by Google this month, starting with Pixel devices.
The feature is available on Android 12 and newer devices with Phone by Google, Contacts and Google Messages installed. It also requires RCS capability in Google Messages.
SAMSUNG MESSAGES ENDING? WHAT ANDROID OWNERS MUST KNOW
There is one key limitation. Both you and the person calling you must use Phone by Google for fake call detection to work.
Phone by Google already comes as the default phone app on many Android devices. If your phone uses a different calling app, you can install Phone by Google from the Play Store and set it as your default phone app.
How Android fake call detection protects you
This feature gives you an extra warning at the exact moment you need it most. That timing is important. Scam calls often rely on emotion. The caller may say someone got arrested, a loved one had an accident or a bank account faces an urgent threat.
SSA IMPERSONATION SCAMS ARE GETTING MORE PERSONAL
When the voice sounds familiar, your guard drops. A warning on your screen can interrupt that emotional rush. It gives you a reason to stop, hang up and verify the story another way.
What Android fake call detection cannot do
This new tool helps, but it cannot protect you from every scam. It may not work if the other person does not use Phone by Google. It also may not cover calls from businesses, unknown numbers or contacts using unsupported devices. So you still need basic scam rules.
If someone asks for money, gift cards, crypto, account codes or remote access to your device, hang up. Then call the person or company back using a number you already trust.
Also, never stay on the line just because the caller tells you to. That is one of the oldest pressure tactics in the scammer playbook.

How to protect yourself from AI voice scams
AI voice scams work because they sound personal, urgent and believable, so your best defense is to slow the conversation down before you act.
1) Create a family safe word
Pick a simple word or phrase that only your close family knows. It should be easy to remember but hard for a scammer to guess. Then, if someone calls with an emergency and asks for money, ask for the safe word. If they cannot give it, hang up and verify the story another way.

2) Pause when the call feels urgent
Scammers want you scared because fear makes people act fast. That is why fake emergency calls often sound intense, emotional and rushed. Take a breath before you do anything. A real loved one, bank or employer will let you verify what is happening.
3) Call back using a trusted number
If a call feels suspicious, hang up. Then call the person back using a number saved in your contacts or one you know is real. Do not use a number, link or instruction the caller gives you. That could send you right back to the scammer.
4) Never send money or codes during the call
Do not send gift cards, crypto, wire transfers or payment app transfers because a caller sounds convincing. Also, never share a one-time passcode, PIN or account login code over the phone. Once scammers get that information, they can move fast.
5) Turn on scam protections on your phone
Use the built-in protections already available on your device. Pixel and Samsung users can enable Scam Detection in the Phone by Google app to help flag suspicious calls. Also, consider using strong antivirus software that includes AI-powered scam protection to help detect scams in texts, online content and deepfake videos. Keep an eye on call warnings too. If your phone tells you something looks risky, treat that alert seriously. Get my picks for the best 2026 antivirus protection winners for your Windows, Mac, Android & iOS devices at Cyberguy.com
6) Keep your phone apps updated
Update Phone by Google, Google Contacts and Google Messages when updates are available. These tools work best when your apps and phone software stay current. Updates often include security improvements, bug fixes and new scam protections.
Here’s how to check for updates on Android:
- Open the Google Play Store app.
- Tap your profile icon in the top right corner.
- Tap Manage apps & device.
- Under Updates available, tap See details.
- Look for Phone by Google, Google Contacts and Google Messages.
- Tap Update next to each app, or tap Update all.
You can also turn on automatic app updates by opening the Google Play Store app, tapping your profile icon, then going to Settings > Network preferences > Auto-update apps. From there, choose whether to update apps over Wi-Fi, over Wi-Fi or mobile data, with limited mobile data or not at all.

Android’s fake call detection is a smart step in the fight against AI-powered phone scams. It recognizes something many people already know: the name on your caller ID no longer proves the person calling you is real. This feature gives Android users another layer of protection when scammers try to hijack trust. Still, the safest move remains simple. Slow down, verify the call and never let panic make the decision for you.

Congress just gave DHS another $70 billion
Congress narrowly voted to fund President Donald Trump’s mass deportation agenda, giving the Department of Homeland Security $70 billion over the next three years.
The house voted 214 to 212 in favor of the reconciliation bill Tuesday, following the Senate’s 52-47 vote last Friday morning. The vote fell largely along party lines. Sen. Lisa Murkowski (R-AK) was the only Senate Republican to vote against it. Rep. Tim Walberg (R-MI), initially voted against the bill — meaning it would have failed — but changed his vote after huddling with House Majority Leader Steve Scalise (R-LA) and Appropriations Chair Tom Cole (R-OK), according to The Hill. No Democrats voted in favor of the funding bill, which was done through a budget reconciliation process to avoid a Democratic filibuster.
In a speech on the House floor ahead of the Tuesday vote, Rep. Mary Gay Scanlon (D-PA) criticized Republicans for using the budget reconciliation process to avoid negotiating with Democrats, and emphasized ICE’s lack of popularity with the American people.
“At its core, this Republican reconciliation budget bill is a statement about priorities, and the priorities represented in this budget bill could not be more out of step with the needs and values of the American people,” Scanlon said.
Scanlon noted that DHS has yet to spend $100 billion of the nearly $200 billion it received under Trump’s One Big Beautiful Bill Act. She added that Trump has not only expanded ICE’s reach by increasingly going after legal immigrants but also weaponized DHS against its critics. The bill, she said, will “supercharge” Trump’s abuses.
After the House markup last Friday, Rep. Rosa DeLauro (D-CT), ranking member of the House Appropriations Committee, noted that the bill not only lacks sufficient reforms but also cuts funding for cybersecurity and TSA, whose workers went weeks without pay during the DHS shutdown.
The funding bill comes at a time of deep unpopularity for ICE. One recent poll found that just 33 percent of voters approve of how the agency is doing its job.
And it comes amid yet another threat from border czar Tom Homan to flood New York City with ICE agents. In an interview with Fox News on Monday, Homan said he would send “more ICE agents than you’ve ever seen” to New York City if the state government passed a bill limiting cooperation with DHS.
“Providing a quarter trillion dollars to an administration promising that the public ‘ain’t seen shit yet’ when it comes to mass deportation is a historic mistake,” Todd Schulte, president of the immigration reform group FWD.us, said in a statement. “Supercharging the funding for these already out of control systems will come with terrible human consequences and continue to be met with increasing opposition from voters.”
Correction, June 9th: A previous version of this story said Rep. Tim Walberg voted against the funding bill. He initially voted against it but then changed his vote to support it.
Update, June 9th: This story has been updated to include comment from FWD.us president Todd Schulte.
