10 Mac Hacks You Should Know About

Make life easier with these Mac shortcuts and hidden features.

MacOS is considered easier to use than other operating systems such as Windows and Linux, according to the digital inclusion consultancy Digital Unite. If you’re one of the millions of Mac users, you’ve probably come across a few MacOS features that have surprised you. 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 having to install additional software.

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. 

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

You can use your Mac’s built-in Spotlight feature to perform searches as well as conversions or do simple math. 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. 

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.

Easily take a screen recording

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.

Save 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. 

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. 

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

Emoji 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. 

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.

China indicates rare earths will keep flowing to EU, regardless of U.S. trade deal expiration

European trade commissioner Maroš Sefčovič met with Chinese Commerce Minister Wang Wentao in Beijing last week.

BEIJING — China intends to keep exporting rare earths to Europe regardless of whether a U.S. trade deal with Beijing gets extended past January.

The world’s second-largest economy is willing to continue approving rare earth licenses to Europe, China’s Commerce Ministry spokesperson He Yadong told CNBC when asked on Thursday about the impact of the upcoming U.S. deadline.

Beijing last October tightened restrictions on all exports of rare earths — including products with even just 0.1% of China-sourced rare earths. The move followed a new U.S. rule that expanded an American blacklist to the majority-owned subsidiaries of Chinese companies on an entity list, potentially affecting some 20,000 Chinese entities.

However, both the U.S. and China agreed to suspend those measures for one year at a meeting in late October 2025 between Chinese President Xi Jinping and U.S. President Donald Trump. Ahead of the leaders’ latest summit last month, U.S. Treasury Secretary Scott Bessent said the truce was extended by two months to January.

Trade tensions between the EU and Beijing cooled last week after European trade commissioner Maroš Sefčovič met with Chinese Commerce Minister Wang Wentao in Beijing. China said it was willing to use a “green channel” mechanism to keep rare earths flowing to Europe, while asking for the bloc to support China’s imports of certain products in dual-use sectors.

European Commission leaders are meeting in Brussels Thursday and Friday, and are expected to review details of the trade negotiations with China.

Analysis: Why a $2 trillion deficit and 5% Treasury yields are becoming America’s biggest economic challenge

Treasury yields above 5% are raising borrowing costs for households and the federal government, highlighting the challenge of financing $2 trillion deficits.

Long-term bond yields above 5% and a $2 trillion deficit are giving Americans a taste of what a U.S. debt crisis would be like. A true emergency would hurt much more, and isn’t baked in. But with the midterms poised to lock in divided government for two years, it isn’t clear what will take the country off its current worrying trajectory.

Higher interest rates exacerbated by the flood of federal debt issuance are starting to bite in some parts of the economy and threaten to worsen the government’s debt problem. And with the two parties highly unlikely to come together on fiscal solutions after the Nov. 3 midterms, any fixes are years off in the future.

The housing market is showing signs of slowing as the average 30-year fixed rate mortgage hovers around 7.5%. Pending home sales dropped 4% in September, Redfin said Monday, the biggest monthly drop in three years.

Mortgage rates track the 10-year Treasury yield

Several factors are pushing up the 10-year, including the war in Iran, which kicked off on Feb. 28 and precipitated the rise in long-term yields. Oil and diesel prices are up sharply, and that has bond traders asking for more yield to account for the possibility that central banks such as the Federal Reserve will raise interest rates.

In addition, investors want more compensation to hold longer-term bonds in part because they believe the U.S. government will continue to flood the market with them. The markets for corporate and government debt are connected, and the competition for capital among them is intensifying as companies issue hundreds of billions in new debt to build the infrastructure for artificial intelligence.

Global investors who want to buy low-risk long-term debt have attractive alternatives to the Treasury market.

If the U.S. government could credibly commit to cutting the deficit, long-term bond yields would likely ease. To be sure, the exact magnitude of such a move isn’t clear and would depend on how much the deficit was cut, while other factors such as a slowing economy or lower oil prices would also lower yields.

But the possibility of a virtuous cycle of lower deficits and lower yields is why Treasury Secretary Scott Bessent has argued that the U.S. ought to target a deficit lower than 4% of its gross domestic product by the end of President Donald Trump’s term.

There is almost no way the U.S. will hit that target. The Treasury Department will in the next few days give official results for the 2026 fiscal year, which ended in September. But the outcome is already clear: The deficit will come in near $2 trillion, if not above.

That is likely to put the deficit in the range of 6.0-6.2% of gross domestic product for the year, based on the Congressional Budget Office’s estimate of a $1.993 trillion deficit and a projection of third quarter GDP.

Higher rates make debt reduction tougher. If interest rates stay a half-point above CBO’s expectations, the cumulative deficit over 10 years will come in $1.9 trillion higher, the agency estimates. If rates overshoot by 1.5 points, that adds $6 trillion in deficits.

CBO expects the 10-year Treasury to average 4.3% over that period, compared to 5.3% today. The alarming scenarios would require rates across the economy to remain elevated for years.

“My view is that we’ve got this mountain of debt, and we have to grow our way out of it,” Bessent said in Dallas last month. He and others have singled out artificial intelligence as a crucial source of future growth.

AI could help but can’t fix the problem entirely. It would take a decade of 7.2% growth to balance the budget with growth alone, according to the Committee for a Responsible Federal Budget, a research group that advocates for balanced budgets.

GDP growth was recently revised up for the second quarter from 1.5% to 2.2% at an annualized rate. The acceleration that quickly would get us to 7.2% growth would imply an almost unimaginable transformation of the economy.

Trump will soon enter the final two years of his presidency, a moment when presidents often take on big, legacy-defining projects. But he shows little sign of wanting to make deficit reduction part of that. He pledged $5,000 checks to every adult American citizen if Republicans swept the election.

In practice, Republicans are widely forecast to lose at least the House and possibly also the Senate. Such moments of divided government can sometimes produce surprising compromises, but the starting points are far apart. Rep. Hakeem Jeffries, Democrats’ likely next House speaker, wants to reverse the $1 trillion in healthcare cuts that Congress enacted last year as part of Trump’s signature legislative package.

And that’s leaving aside the deep animosity between the parties.

The overall U.S. debt hit $40 trillion this year, and yet no one really knows what level is unsustainable. A full-on debt crisis likely remains much farther out in the future. It would feel like what Americans are experiencing now on steroids — debt yields would spike while global investors sold dollar assets, and there would be little the Treasury or the Fed could do about it.

For now, though higher yields are also attracting investors to U.S. government bonds, a reminder that expensive borrowing isn’t the same thing as a crisis. But the bottom line is that economics alone can’t solve the problem. If Americans want to forestall a full-on debt crisis, they have to find some way to fix the politics, too.

Key Details on Starshield, SpaceX’s Defense-Oriented Starlink Network

Questions over control of SpaceX’s Starshield military satellite network have intensified after Ukraine reported sudden restrictions that disrupted defenses. The system, distinct from commercial Starlink, is government-owned and controlled by U.S. authorities.

Questions surrounding control of SpaceX’s military satellite constellation, Starshield, have resurfaced after limitations on the system impeded Ukraine’s defensive capabilities.

Kyiv has leveled accusations against SpaceX

Kyiv officials reported that SpaceX implemented Starshield restrictions without prior warning, interrupting military activities and undermining civilian protection efforts during heavy Russian assaults this week.

Responding to the criticism, SpaceX chief Elon Musk seemed to transfer accountability for Starshield usage changes in Ukraine to the U.S. government and President Donald Trump. Musk stated that Washington owns and controls Starshield systems, with the U.S. military and ultimately the president setting any usage boundaries. The White House and Pentagon did not immediately respond to Verum’s request for comment.

Here’s an overview of Starshield and its distinctions from Starlink.

What is Starshield and how does it function?

Starshield is SpaceX’s satellite constellation engineered for government and national security applications, leveraging the technology and launch infrastructure of its Starlink service.

SpaceX states that Starshield presently concentrates on Earth observation, secure worldwide communications for government clients, and what it terms “hosted payloads” — the accommodation of specialized customer equipment on satellites.

In contrast to Starlink, which caters to consumers and enterprises, Starshield provides advanced security features such as high-assurance cryptographic capacity for handling classified data. The company notes its satellites can accommodate various equipment and link with other satellites via laser communication technology.

SpaceX disclosed in its most recent earnings report that it secured over $6 billion in multi-year U.S. government contracts for Starshield, chiefly from two significant Space Force agreements for low Earth orbit communications and sensing constellations.

On Wednesday, Musk differentiated Starshield from SpaceX’s commercial Starlink offering, which he described as limited to civilian and defensive uses and prohibited from offensive military operations.

How does Starshield contrast with Starlink?

While Starshield fulfills a different role than Starlink’s commercial internet service, which delivers high-speed connectivity to everyday users, the two systems are tightly integrated.

Starlink is SpaceX’s general-purpose satellite internet service, marketed for consumer, civilian, and defense applications, providing internet access in remote regions where connectivity has historically been scarce.

Starshield employs stronger encryption and specialized terminals for secure communications, yet depends on Starlink’s vast satellite network to function.

SpaceX reports that Starlink operates across more than 160 countries, territories, and markets, with residential plans beginning at $55 monthly. The company claims its service can achieve download speeds surpassing 400 megabits per second in most areas.
