What Is Rosetta 2 on Mac?

#Rosetta #Mac

If you have a Mac that uses Apple Silicon, you might have heard about Rosetta 2. It’s a critical part of macOS that enables compatibility with applications designed for Intel Macs. We’ll explain.

Rosetta Lets Intel Mac Apps Run on Apple Silicon

As you probably know, Apple has been transitioning its Mac lineup to use its own custom-designed processors based on the Arm architecture. Apple released the first Macs with Apple Silicon in November 2020. While most apps have been updated to run natively on Apple Silicon, there are still some that haven’t been updated yet. That’s where Rosetta 2 comes in.

Rosetta 2 is a translation layer for running Intel-based apps on Apple Silicon Macs. It uses dynamic binary translation to convert x86_64 code to the Arm64 architecture used by the M1 and M2 chips. It allows these new Macs to run apps that haven’t been updated to run natively on Apple Silicon.

Apple first introduced Rosetta 2 with the release of macOS Big Sur 11.0 in 2020. Its name is a reference to the Rosetta Stone, which was the key to translating many ancient texts. The “2” at the end of the name refers to the fact that it is the second version of the Rosetta translation later. The original Apple Rosetta allowed PowerPC apps to run on Intel Macs back in 2006.

How to Use Rosetta 2

If you own an Apple Silicon Mac, macOS will automatically install Rosetta 2 when you first try to run an Intel app that hasn’t been updated to run natively. Upon the first run, you’ll be prompted to install Rosetta 2. When you see the “You need to install Rosetta” window, click “Install.”

Once Rosetta 2 is installed, it will silently translate Intel Mac apps that aren’t yet native to Apple Silicon on the fly. This means that you shouldn’t notice any difference in performance when running an app through Rosetta 2. It’s very impressive how well it works.

More Rosetta 2 Tips

If you’re not sure if an app is running in Rosetta 2, you can check by opening the Activity Monitor app. In Activity Monitor, select the CPU tab. If an app is running in Rosetta 2, it will be labeled as “Intel” in the “Kind” column.

In "System Information" look for "Apple Silicon" in the "Kind" column.

Also, if an app is a Universal Binary (which means it can run natively on both Intel and Apple Silicon Macs), you can force the app to run in Rosetta 2. Normally, you don’t want to do this, but sometimes the Intel version of the app might be different than the Apple Silicon version.

To force an app to run in Rosetta 2, locate it in Finder, right-click the app’s icon, then select “Get Info.” In the Get Info window, check the box beside “Open Using Rosetta.”

In the "Get Info" window, check the box beside "Open using Rosetta."

After that, close the Info window and run the app from that icon. It will load in Rosetta 2. Ideally, you won’t need to do that, but the option is always there if you want. Good luck!

Efficient growth? No problem, bootstrapped startups say

Welcome to The TechCrunch Exchange, a weekly startups-and-markets newsletter. It’s inspired by the daily TechCrunch+ column where it gets its name. Want it in your inbox every Saturday? Sign up here.

Investors these days want to see not only growth, but also a path to profitability — and it isn’t always easy for venture-backed startups to suddenly correct course. But their bootstrapped peers have a leg up, a recent report shows. Let’s explore. — Anna

Cheaper growth

In 2021, Alex and I wondered out loud if startups eschewing venture capital could have it all. The answer this year seems to be yes.

Indeed, Capchase’s recent Pulse of SaaS report contains an interesting finding: In 2022, bootstrapped SaaS companies are doing better than VC-backed startups in many respects.

“Despite the war chest of funding that VC-backed firms raised last year, bootstrapped companies are doing better than VC-backed companies across nearly every metric we analyzed,” the SaaS-focused fintech wrote.

Exclusive: My Favorite 4K Blu-ray Player Is $100 Off for Cyber Monday – CNET –




My Favorite 4K Blu-ray Player Is $100 Off for Cyber Monday     - CNET

#Favorite #Bluray #Player #Cyber #Monday #CNET

We’ve said goodbye to the Black Friday week, but we’re not quite done with the deals just yet. Cyber Monday is only a few days away, and the vast majority of discounts are still available, with a ton of new ones coming every day. One of my personal favourite deals is this price drop on the fantastic Panasonic UB820 4K Blu-ray player. It’s only $398 for Cyber Monday, down from its regular price of $500. If you’re someone who loves movies, both new and old, then you owe it to yourself to get the best possible movie-watching experience, something this 4K Blu-ray player can offer.

The Panasonic UB820 isn’t the most expensive player out there, but it is considered by the majority of enthusiasts as the Holy Grail of 4K Blu-ray players. Along with my LG C-series OLED TV (which is also on sale for Cyber Monday), it’s my favourite way to watch movies thanks to its support for gorgeous Dolby Vision HDR and immersive Dolby Atmos sound.

4K Blu-rays are capable of offering the best quality image, audio, and HDR for any movie that’s available on the format. 4K streaming on Netflix is only transmitted at 25Mbps, while a 4K Blu-ray transmits it four times faster. This results in a superior experience when it comes to every aspect of movie watching.

Another great thing about 4K Blu-rays is that old movies that were shot on 35mm film can be shown at their highest quality since first being projected in theatres. That’s because 35mm films can roughly be equated to 8K resolution, allowing them to be blown up to a huge size without losing image detail in the theatre. So if the original 35mm film negatives have been preserved and taken care of, studios can have the work done to make magnificent presentations on 4K Blu-ray. Some of my favourite 4K Blu-rays that exemplify this are Heat, Raging Bull and Casino — yes, I’m quite the De Niro fan.

Many companies and boutique outlets may also work with the director and/or cinematographer to create a presentation that matches their original intent, giving you an experience that’s as close to seeing it in the theatre as actually being there in the past.

Exclusive: New EU legislation allows airlines to provide in-flight 5G connectivity –




New EU legislation allows airlines to provide in-flight 5G connectivity

#legislation #airlines #provide #inflight #connectivity

Something to look forward to: Airline passengers have become accustomed to either completely cutting themselves off from the outside world or paying additional charges for in-flight Wi-Fi access. But thanks to new legislation passed by the European Commission, passengers aboard European Union-based flights may soon be able to use all of their device’s standard mobile features while in flight.

On Thursday, the European Commission announced that EU-based airlines will now be allowed to provide in-flight wireless 4G and 5G access for all passengers. Once implemented, passengers can use their mobile devices in the same ways as any ground-based mobile network while in flight. Goodbye airplane mode; we can’t say it’s been fun.

An onboard “small cell” network established using picocells will provide the in-flight service. Small cells function as miniature, low-power cell towers that augment typical cell towers by filling in coverage gaps and offloading cellular traffic. The result is a broader, more reliable cellular network that delivers high data rates and easier deployments using simple, cost-effective cellular solutions.

Picocells are a specific type of small, low-cost small-cell technology that can support between 32 and 64 individual users while providing up to 250m in-network coverage. Their size and ease of deployment indoors or outdoors make them ideal for augmenting and improving the range within facilities and structures such as schools, shopping centers, and other small businesses. Once deployed to participating aircraft, the cells will route calls, texts, and other mobile data between the plane and ground-based mobile networks.

The European Commission’s Thierry Breton, a commissioner for Internal Market, sees the new legislation as a potential catalyst to drive new EU-based services and business growth.

“The sky is no longer a limit when it comes to possibilities offered by super-fast, high-capacity connectivity,” Breton said.


The push to expand 4G and 5G access will likely extend beyond air travel. The Commission also amended a decision on 5GHz, making the bands available for use in cars, buses, and other forms of transportation. The amendment to the implementing decision says that Member States shall make the 5GHz frequency bands available for use aboard road vehicles no later than June 2023.
