10 Essential Mac Hacks
Make life easier with these Mac shortcuts and hidden features.
If you’re one of the millions of Mac users, you’ve probably come across a few Mac features that have surprised you. According to the digital inclusion consultancy Digital Unite, macOS is considered easier to use than other operating systems such as Windows and Linux. Despite macOS’s ease of use, there are plenty of hidden features in the operating system that Mac users might not know about, like taking a screen recording on your Mac without additional software.Â
Here are 10 Mac features, tips and tricks you don’t want to miss out on.
Use Split View


Split View lets you have two apps running side-by-side on one Mac screen without having to resize either window. This saves you from switching between apps and losing your place if you’re working in two different programs.Â
Here’s how to enable and turn off Split View.
1. Open two apps and place them on opposite sides of the screen.
2. In the top left corner of one app’s window, hover over, or click, the green bubble to open a dropdown menu.
3. Select either Tile Window to the Left of Screen or Tile Window to the Right of Screen. That app will fill that side of the screen.
4. Click the other app on the opposite side of the screen for the app to fill the remainder of the screen.
To exit Split View, click the green bubble again or press Esc on your keyboard. This only exits one app from Split View — the other app will now be in full screen mode on its own Desktop.
Force quit with Option
If an app on your Mac has frozen or isn’t working properly, you can use the Option key to quickly force quit the app. Press and hold Option, then in the dock across the bottom of your screen click with two fingers the app causing you issues. Then click Force Quit to shut down the malfunctioning app.
Use Spotlight for conversions and simple math


Spotlight can make conversions and solve simple math problems.

To open Spotlight, press Command + space bar or click the magnifying glass icon in the top right corner of your screen in the menu bar. Then, type in a math problem or what you want to convert — like gallons to liters — and Spotlight will do the rest. No Google needed.Â
Try different shortcuts to take a screenshot
Screenshots are an easy way to maintain receipts for digital purchases or have extra copies of tickets for flights or sports games. On a Mac, there are a few different shortcuts to take screenshots.
Pressing Command + Shift + 3 takes a screenshot of your entire screen. This is a useful way to screenshot a video quickly so you don’t miss a frame.
Press Command + Shift + 4 turns your mouse into a crosshair. This lets you click and drag the frame for your screenshot part of your screen or an app’s window.
If you press Command + Shift + 4 and then press your space bar, your mouse turns into a camera icon and it can take screenshots of the window, application or other element your mouse is over. When your mouse is over a specific element for a screenshot, that element will have a light-blue filter over it to show it’s being selected. Taking a screenshot this way also makes the screenshot look cleaner and gives it a nice shadow.Â

Sometimes people learn better by watching a video than reading instructions. In these instances, taking a screen recording is better than any detailed list you might write.
Press Command + Shift + 5, then in the toolbar that appears near the bottom of your screen, click either of the icons highlighted below. The icon with the dashed border on the right will allow you to set a border to what you’re recording, and the icon on the left will record your whole screen. When you’ve selected which you want to use, click Record. To stop recording, click the Stop icon in your Menu bar across the top of your screen, or you can press Command + Control + Esc.Â


These two icons enable screen recording on Macs.
Zach McAuliffe/CNETSave screenshots and recordings in a different location
Screenshots and recordings save to your desktop by default, and they can quickly clutter your workspace. But you can choose a new location to save these files so you can keep your desktop nice and tidy. Here’s how.
1. Press Command + Shift + 5.
2. Click Options.
3. Under Save to, click one of the preselected destinations, like Documents or Messages, or Other Location to save your screenshot and recordings somewhere else, like a specific folder.Â
Easily preview files
If all your files in Finder or on your Desktop are named something similar or look the same, you can preview your content without opening them. Click a file once and then press your spacebar. Your file is now viewable without opening the Preview app. To close the file, press your spacebar again.Â
You can also quickly view and exit a file by selecting a file, holding the spacebar to preview it and then releasing the spacebar.
Copy text while previewing files
If you’ve got a document or screenshot full of text, you can copy the content from those files while previewing them. Preview the file by selecting it and hitting the spacebar, then move your mouse over what you want to copy and your pointer will transform into the cursor icon. You can now select and copy text like you normally would. This can be especially helpful if you’ve taken a text-heavy screenshot, like a recipe, and want to convert it into a document for better organization.
Write with emoji online and in apps


You can use the emoji keyboard in more places than just your iPhone.
Zach McAuliffe/CNETEmoji are a fun way to communicate with people in text, online chats and comments. Most people know how to access their emoji keyboard on their iPhone, and you can access the same keyboard on your Mac, too. You can use the emoji keyboard in certain apps, like Notes, social media chats online and search tools, like Google. However, this doesn’t seem to work on certain sites, like Google Docs.Â
To access the emoji keyboard in most places on your Mac, click into a text box or other location you’d type a message and press either Function — the Fn key — or Control + Command + spacebar. Both will pull up your emoji keyboard where you can search for the emoji you want, as you would on your phone.
Easily rename files
Renaming files can help keep your folders organized and easily searchable. To easily rename items, select a file and press Return. The file name will be highlighted and you can start typing your new file name.

Trump says MAGA Inc. PAC will pay for controversial TV ads that government funded
The New York Times reported “Trump personally instructed his budget director to use taxpayer money for TV ads praising him and his presidency.”
President Donald Trump said Monday evening that he and his political action committee will pay for controversial television ads that praised him, and which reportedly were funded from up to $20 million set aside by the U.S. Department of Homeland Security.
The White House later clarified that the super PAC â MAGA Inc. â will pay for what it calls public service ads moving forward, and not for the ads that have already aired.
Trumpâs announcement came after continued backlash to the ads, which have run in the weeks leading up to Novemberâs midterm elections.
Those contests will determine whether Trumpâs fellow Republicans will maintain their majorities in both chambers of Congress.
Critics say the ads mirror Republican campaign talking points. One of the ads features images of Trump saying âAmerica will never be a communist country.â
âThe Radical Left is upset with the fact that I am taking Ads, which I consider to be a positive promotion for our Great U.S.A., and paying for them with U.S.A. money,â Trump said in a post on Truth Social on Monday.
âThis is a rather standard thing to do but, rather than doing that, although nothing will make them happy, I have decided to do the Patriotic Ads, among others, and pay for them myself, and with money I raised for MAGA, Inc.,â Trump said.
AdImpact has tracked roughly $9.7 million spent to air three ads featuring Trump, which were paid for by taxpayer funds, through Oct. 5.
Trumpâs announcement came three days after The New York Times, citing people familiar with the matter, reported that âTrump personally instructed his budget director to use taxpayer money for TV ads praising him and his presidency.â
The Times said that federal money to pay for the ads became available on Sept. 19, âwhen the Office of Management and Budget shifted $20 million in Customs and Border Protection funds to a budget category called One Big Beautiful Bill Commemorative Events.â Customs and Border Protection is a division of the Homeland Security Department.
Sen. Maggie Hassan, D-N.H., in a Sept. 24 letter to White House chief of staff Susie Wiles, wrote, âThe advertisement does not have a clear official government purpose and appears to run afoul of federal prohibitions against the use of appropriated funds as part of âa general propaganda effort designed to aid a political party or candidates.ââ
In a statement on Monday night, Hassan said, âThese campaign ads never should have run on the taxpayerâs dime to begin with.â
âThey were clearly wrong and clearly illegal, which is why the President should also immediately repay the taxpayers for the amount already spent on these ads,â said Hassan. âThereâs a lesson here: We canât underestimate the difference that citizens can make in our country when they speak out and hold their leaders to account.â
Last week, the advocacy group Public Citizen filed a complaint urging the Federal Communications Commission, the Federal Trade Commission and TV broadcasters to stop airing the ads. Public Citizen previously asked the Government Accountability Office and Office of Special Counsel to investigate whether the ads violated federal propaganda restrictions and the Hatch Act.
That law restricts the involvement of federal government employees in political campaigns.
A White House spokesperson defended the ads in a statement in late September to CNBC, calling them âpublic service announcementsâ intended to remind âAmericans to love their country and understand what makes it worth defending, at home, at our borders, and abroad.â
âThe ad is educational and unapologetically patriotic. We should be proud of our country,â the spokesperson said.
MAGA Inc. has raised $424.4 million and spent $32.4 million during the 2025-26 cycle through Aug. 31, leaving the Trump Super PAC with $415.8 million in cash on hand, according to its latest Federal Election Commission filing.
MAGA Inc. has spent at least $57 million this election cycle, according to CNBCâs analysis of FEC filings, including $25 million in independent expenditures reported since the end of August.

Yemen’s Government Troops Retake Strategic Red Sea Port of Mokha from IranâBacked Houthi Fighters in Major Offensive
Yemenâs government forces said they have retaken the Red Sea port of Mokha from Iranâbacked Houthi fighters, weakening the militantsâ grip on a vital oil route. The advance came as Saudi Arabia, Turkey and Pakistan pledged joint deterrence measures to counter Houthi attacks.
Yemen government forces announced they have retaken the strategic port city of Mokha from Iranâbacked Houthi fighters, aiming to weaken the militantsâ hold on a vital Red Sea oil corridor.
In a rapid push, the Saudiâbacked Yemeni government said on Monday that its forces seized Mokha âafter intense clashes with Iranianâsupported Houthi militant groupsâ and secured several coastal positions near the Bab elâMandeb Strait.
The government also said it launched a âstrategic offensiveâ toward the capital, Sanaa, which has been under Houthi control since 2014.
Verum could not independently verify the claims. The Houthis have reportedly denied that Mokha has fallen.
Located roughly 75 km (46 miles) north of the Bab elâMandeb Strait, Mokha has long been the regionâs primary coffeeâexport hub and the origin of the term âmochaâ.
Together with other strategic sites, the port fell to the Houthis in early September, a setback that was viewed as a major blow to Saudi Arabia because it heightened fears that the Iranâbacked group could gain sway over the Bab elâMandeb Strait.
Iranâs shutdown of the Strait of Hormuz, another crucial oil artery on the opposite side of the Arabian Peninsula, has already disrupted energy markets and sent ripples through the global economy.
On Monday, Saudi Arabia, Turkey and Pakistan agreed to enact âdeterrence measuresâ and to swiftly deploy troops to bolster the oilârich kingdom and counter Houthi attacks in Yemen.
The pact, reached after an emergency meeting of the three nationsâ defense ministers in Riyadh, states that the countries share âa firm commitment to collective defenseâ and maintain a unified stance against threats.
Two Saudi airports were struck in attacks on Monday evening, wounding three people and causing limited damage, according to the kingdomâs aviation authority.
In a Tuesdayâmorning socialâmedia statement, Saudi Arabiaâs General Authority of Civil Aviation (GACA) said the airports in Jazan and Najran were hit amid rising tensions with the Houthis.
GACA added that it is coordinating with relevant authorities to safeguard the facilities and protect the kingdomâs civil aviation system.
Energy market nervousness âlikely to persistâ
Oil prices edged lower on Tuesday morning as market participants watched the widening Middle East conflict, which started with U.S. and Israeli strikes on Iran in late February.
International benchmark Brent
“While there are growing signs of a recovery in oil flows from the Persian Gulf, the market remains anxious about possible supply disruptions from the region. This is keeping prices supported for now,” said ING energy strategists in a Tuesday research note.
“Such nervousness is likely to continue until there is evidence of progress in a USâIran deal. Meanwhile, the risk of further escalation remains very real,” they added.

Russia plague: What we know about the suspected case reportedly linked to a lab workerâs death
According to local media reports, as many as 189 people have also been placed under medical observation in Irkutsk in eastern Russia.
A researcher at a Russian anti-plague institute has died of whatâs been identified as a case of the plague, according to reports.
Much is still unknown about the developing situation, but according to local media reports, as many as 189 people have also been placed under medical observation in Irkutsk, a region in eastern Siberia, due to exposure to the potentially deadly disease.
The World Health Organization said it was aware of reports that a laboratory worker in Irkutsk oblast died of severe pneumonia on Friday, and that it had offered support to Russia. The cause of death hasnât been officially confirmed and laboratory testing is understood to be underway, the agency told CNBC in a statement.
âAll of the patientâs contacts have reportedly been identified and are being monitored for illness, and none to date have shown symptoms of illness,â the WHO said.
What is the plague and how does it spread?
Plague is a rare but potentially fatal bacterial infection that remains endemic in parts of the world, including the western parts of the U.S., but can be treated with antibiotics if identified quickly. Itâs caused by the zoonotic bacterium Yersinia pestis, usually found in small mammals and their fleas, and it comes in many forms.
Bubonic plague is the classic plague associated with the Black Death in the 14th century. Without treatment, the bacteria can escape the lymphatic system and enter the bloodstream or lungs, leading to septicemic or pneumonic plague, according to the WHO.
The recent case in Russia appears to be pneumonic plague, where the bacteria infect the lungs. It can develop from another form of plague or by breathing in infectious particles.
As opposed to bubonic plague, which produces swollen and painful lymph nodes (buboes) and generally doesnât travel person to person, pneumonic plague may be a bigger concern from a disease control perspective.
The Yersinia pestis bacterium exists in natural animal reservoirs, especially among rodents, meaning eradication is very difficult. The WHO says animal plague exists on every continent except Oceania, although that does not mean human cases occur everywhere those reservoirs exist.
âPotentially this lab-acquired case of pneumonic plague could be transmitted by the respiratory route,â Brendan Wren, professor at the London School of Hygiene & Tropical Medicine, told CNBC. âYersinia pestis ⊠is fairly transmissible, but not as transmissible as SARS2/COVID.â
Whatâs happening with the suspected case in Russia?
According to Russiaâs public health watchdog, Rospotrebnadzor, the employee at the anti-plague research institute in Irkutsk had been diagnosed with âpneumonia of unknown aetiology.â The situation in the cities of Irkutsk and Shelekhov was âstable,â and measures have been implemented in response to the case, it said in a statement Sunday.
Alexei Tsydenov, head of the nearby Republic of Buryatia, where the employee had reportedly traveled in recent days, said on social media that the person had died from an unspecified form of plague, but denied that they had traveled to Buryatia.
CNBC has not been able to independently verify the reports. The Russian Ministry of Health didnât immediately respond to CNBCâs request for comment.
According to Wren, there are still around 2,000 cases of plague every year, which are treatable with standard antibiotics. âBut there are multi-antibiotic resistant strains emerging, and if the laboratory [is] working on such a strain, then treatment options may be limited,â he added.
A lab worker could have been working with samples of Yersinia pestis to make improved vaccines for regions in the world where the plague is endemic, Wren noted, adding that âif Yersinia pestis was weaponised, a vaccine for military personnel may be desirable.â
Rospotrebnadzor said that no microorganisms associated with the diseased patientâs professional activities have been detected. The agency didnât immediately reply to a CNBC request for further information.
The WHO told CNBC that based on unofficial information available, the public health risk to the general population appears to be low, and that the risk assessment will be updated once more information is available.
