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 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.

Meta is adding ridiculous ‘rate limits’ and a soft paywall to its smart glasses

Meta is adding ridiculous ‘rate limits’ and a soft paywall to its smart glasses

Would you pay $20 a month for access to AI hardware you already own? That appears to be one of Meta’s next bets. This week, it quietly announced that your glasses’ Conversation Focus feature will soon be limited to three hours of use per month, unless you pay for a $19.99 Meta One Premium subscription.

In a help article, the company insists that it won’t require a subscription to use your glasses, period; it’s merely erecting a “rate limit” for certain AI features. Even premium subscribers will only get 15 hours of Conversation Focus per month under that “rate limit,” it claims.

Problem is, Meta’s rate limit is ridiculous. The Conversation Focus feature, which amplifies the voice of the person you’re speaking to so you can hear better in noisy environments, is not something that should plausibly be rate-limited, because it doesn’t use Meta’s servers. It runs on-device, using the chips inside the glasses that you’ve already purchased. I turned off my internet, and it kept working.

Here’s how the company introduced it last year: “[C]onversation focus uses your AI glasses’ open-ear speakers, beamforming technology, and real-time spatial processing to dynamically amplify the voice of the person you’re talking to.”

Not only does it avoid Meta’s servers, but Conversation Focus doesn’t technically require an internet connection at all. I double-checked by turning off my phone’s Wi-Fi and cellular, turning on Airplane Mode, and I was still able to use Conversation Focus just fine by tapping a button on my phone.

Does Meta have some secret licensing deal with another company that costs it money every time a person uses Conversation Focus? Failing that, the rate limit sounds utterly bogus.

We’ve asked if Meta can explain the move, and whether the company plans to put other on-device features behind a subscription. Meta didn’t immediately respond to a request for comment.

Warehouse robots move packages without human handoff

Warehouse robots move packages without human handoff

NEWYou can now listen to Fox News articles!

A busy warehouse loading dock can be a grind. Trucks pull up. Packages pour in. Workers have to move fast, lift heavy boxes and keep everything flowing before the next trailer arrives. That part of the warehouse has always been one of the hardest places to automate. Every box can be a different size. Freight can shift in transit. Labels may face the wrong way. And when one system finishes a task, the next system still has to know what to do with the package.

Now, Ambi Robotics and Pickle Robot Company say they have linked their robotic systems to help solve that handoff problem. The companies announced a commercial integration that connects Pickle Robot’s trailer-unloading robots with Ambi Robotics’ AmbiStack pallet-building system. In other words, one robot system unloads mixed freight from a trailer. Then a conveyor moves those cases downstream so another robotic system can scan and stack them for warehouse receiving.

If this works well in large facilities, it points to a future where robots can handle more of the work that happens between a truck and a warehouse floor.

OHIO ROBOT COP RETIRES AFTER ZERO ARRESTS

How warehouse robots move packages from truck to pallet

The setup starts at the trailer. Pickle Robot’s system unloads boxes from trailers or containers. That matters because unloading mixed freight can be exhausting work. It also creates bottlenecks when warehouses do not have enough people on the dock. From there, the packages move by conveyor into AmbiStack. Ambi Robotics designed AmbiStack as a multipurpose stacking system. It reads package information and builds pallets for the next stage of the warehouse process.

The key here is the handoff. Many warehouses already use automation. However, those systems often work in separate lanes. One machine may handle unloading. Another may handle sorting or stacking. Yet the warehouse still needs people or custom engineering to connect the pieces. This collaboration tries to make that connection smoother. The companies say the system can work with existing warehouse infrastructure. That means operators may avoid tearing apart a facility to use it.

Why Physical AI is important for warehouse automation

Physical AI means AI that controls machines doing physical work. That is important here because warehouse robots have to deal with moving boxes, shifting freight, conveyor timing and pallet stability. That creates a very different challenge from software that writes a paragraph or answers a question. A warehouse robot has to react to what sits in front of it. A box can arrive dented. A label can face the wrong way. A pallet can become unstable if the next case goes in the wrong spot.

This Ambi Robotics and Pickle Robot integration shows how that can work inside a warehouse. Pickle Robot handles the trailer unloading. AmbiStack takes over downstream by scanning and stacking cases for receiving. Together, the systems show how specialized robots can connect across a warehouse workflow.

“Warehouse operators shouldn’t have to choose between best-in-class technologies and seamless integration,” said Jim Liefer, CEO of Ambi Robotics. “As Physical AI transforms supply chains, interoperability will become increasingly important.”

AJ Meyer, founder and CEO of Pickle Robot Company, put the customer demand more directly: “Customers want automation that improves real-world throughput while fitting into existing operations.”

AI MAY SPOT DEADLY HEART RISK IN A ROUTINE ECG

Why loading docks can slow warehouse operations

Anyone who has waited on a delayed package knows the supply chain can break down fast. Sometimes the problem starts long before a delivery truck reaches your home. Inbound logistics covers the work that happens when goods arrive at a warehouse. That includes getting boxes off trailers and moving them into the right workflow. It sounds pretty straightforward until you see the reality.

Trailers can be packed unevenly. Boxes can arrive in odd shapes. Warehouse teams also deal with tight schedules and physical strain. That is why loading docks have become such a major focus for automation. If robots can unload freight and pass it into a pallet-building system without constant human intervention, warehouses could move goods faster through one of the most labor-heavy parts of the operation.

How warehouse robots could change jobs

The big question is obvious. What happens to workers? Robots can take over repetitive and physically demanding tasks. That may reduce injuries and help warehouses handle labor shortages. It may also change which jobs companies need most.

Instead of spending a full shift unloading trailers, some workers may monitor the unloading and stacking systems. Others may step in when a package jams, a label fails to scan or a pallet needs human attention.

Still, that shift can feel unsettling. Automation often comes with a promise of safety and efficiency. Workers want to know where they fit in next. That is very important. A robot may move a box, but people still handle judgment calls, customer issues and fast decisions when the workflow changes.

Why retailers want connected warehouse robots now

Retailers and logistics companies feel pressure from several directions. Consumers expect faster shipping. Warehouses face staffing challenges. Meanwhile, e-commerce keeps creating more package volume. That creates a hard math problem. Companies need to move more goods without slowing down at the dock.

This Ambi Robotics and Pickle Robot setup gives warehouse operators another option. Instead of buying one giant system from a single vendor, they can connect specialized robotic tools that handle different parts of the job. That could give operators more flexibility. It could also help them avoid major redesigns, which can be expensive and disruptive. In other words, the robots are getting smarter. They are also starting to work together in more useful ways.

What this means to you

Even if you never set foot in a warehouse, this kind of automation can affect your life. When warehouses move goods more efficiently, stores may restock faster. Online orders may move with fewer delays. Returns may get processed more quickly. There is another side, too. More automation can reshape job roles inside warehouses. That means workers may need new training as companies bring in more robotic systems.

You may also hear fewer excuses when packages run late. If robots help warehouses operate with fewer bottlenecks, retailers may raise expectations for speed even more. That sounds convenient, but it also means the race for faster delivery keeps putting pressure on every part of the supply chain.

Kurt’s key takeaways

What grabs me here is the handoff. One robot unloads packages from a trailer. Another scans and stacks them for the next part of the warehouse process. That is the piece that could change how loading docks operate. Warehouses are full of little delays that add up fast. If a package sits in the wrong place or waits for a person to move it to the next step, the whole process can slow down. This integration shows how warehouse robots may start taking over more of that middle work between the truck and the warehouse floor. Still, the human side deserves attention. These systems could reduce backbreaking work, which is a good thing. At the same time, they may change what warehouse workers are asked to do. The companies that make that transition clear, fair and useful for workers will be the ones to watch.
