A tool to deep clean your Mac



Ilustração BuhoCleaner para Mac

macOS is an operating system that excels in organization and simplicity. Applications are “folders” and the ease of space management often leads the user to neglect this task. Since all users are collectors of anything and everything, Macs may need a good cleaning after a few years. To do this, the user can do it manually or ask for help. This is where BuhoCleaner comes to the rescue.

This tool simplifies tasks such as cleaning up abandoned, duplicated, rejected files, and even freeing your computer of stuff that just hangs on resources. Let’s get to know this app.

Over time, as efficient as macOS is at managing installs, uninstalls, space management, and simple storage, we end up with junk that doesn't make any sense to take up space and throw it away.

We can perform manual cleanups, but we never go into the back alleys of our computer to clean up the folders containing these pieces of software, duplicate files, abandoned applications, and more from disk junk.

Thus, there is nothing better than resorting to tools to solve this problem. Today let's talk about one of these tools which we found for this task and which brought us good results, we are talking about BuhoCleaner.

So what is BuhoCleaner good for?

Briefly and in a list, these are the highlights of this tool to clean and manage your Mac:

  1. Cleaning "useless files" to free up space
  2. Remove unused apps
  3. Large File Management
  4. Search for duplicate files and folders
  5. Manage startup items when you turn on your Mac
  6. optimization tools
    1. Manage (visual) storage
    2. File Shredder'
    3. clearing RAM
    4. Reindexing Spotlight Search
    5. clearing the cache

So, these are the recommendations that the user will find when using the application.

1# Clean up "useless files" to free up space

The first button in the sidebar of BuhoCleaner's tools is "Flash Cleaner". After the user selects the "Analyze" option, the program finds and cleans up files that it considers useless for the operation of its machine.

This is a feature that is essentially designed to clean up your Mac.

After the program runs the machine analysis task, the options shown offer a report with a "System Recycle Bin" as well as a user's recycle bin and even a "browser recycle bin".

From here, the user can go two ways:

  • Click on the "Delete" button, which will remove the files automatically selected by BuhoCleaner;
  • Click "View Details" to manually select the file types to delete.

If you want this tool to view your Mac's files, you'll need to give your administrator permission to proceed. To do this, click on "Grant access" in the window that appears on the screen.

2# Remove unused apps

The second main menu gives us access to the "Uninstall Application" option.

More than a tool for:

  • List of all installed applications (and how much space each of them takes);
  • "Remains" of applications are moved to the Trash;
  • A list with everything that the user has selected in this window to delete (both files and applications);
  • List of "big and old" apps (that are over 100MB and/or haven't been opened in the last three months;
  • List of applications organized by origin (App Store and others);
  • List of apps organized by developers.

Essentially, this cleanup app mimics what we know about the Windows Control Panel and helps the user get rid of both apps and "leftovers" from them.

3# Large file management

The Large Files tool is designed to show the user your files that weigh more than 50 MB.

These items are divided into the following categories:

  • Audio;
  • Video;
  • Pictures;
  • The documents;
  • files;
  • Other files.

Of course, these files do not belong to the same category as previously discarded garbage. These are files that may be of interest to put on disk, as they may be consumable. The purpose of this tool is to work like a heavy duty file manager to make it easier to free up space on your Mac.

That is, carefully analyze each file that you plan to delete using this tool from BuhoCleaner.

4# Search for duplicate files and folders

This is always a problem on all computers. We are creatures by nature who collect, store and leave for life stored things that we do not know if they will ever be needed. Moreover, since there are moments that never repeat, we tend to double and sometimes triple the digital material that is now the target of our quest to preserve.

So this tool takes that into account and created the "Duplicates" option. Basically, this is a feature that works differently than the ones mentioned so far in this list. Here the user will have to select folders that BuhoCleaner will analyze, looking for duplicate files and subfolders - that is, with the same size and content.

To do this, the user needs to click on the big button with the “+” sign. At the same time, the program shows recommendations for folders to run the analysis. You can choose one of them and/or click "Choose Custom Folder" just below to choose another. After that, click "Select".

After analysis, BuhoCleaner shows everything it found in duplication state on Mac. Items are divided into tabs: all items, folders, documents, and other files. Then just choose which ones you want to delete and click "Delete".

5# Launch item manager

Startup Items is the fourth button on the sidebar of BuhoCleaner. Shows programs that automatically open when the user turns on their machine and logs into the Mac.

Even in the report generated by this tool, these applications are divided into two categories.

  • User Login Items: These are applications that launch automatically when you log in, i.e. when you enter your password or use Touch ID;
  • Home Services: Programs that open automatically when you turn on your Mac.

Both lists have a selector before each element.

By clicking on this selector, these applications will be activated or deactivated when the operating system is initially executed (when the machine is started).

6# Optimization tools

The last button on the sidebar of BuhoCleaner has a pretty name: Toolbox. This "kit" contains five tools aimed at optimizing your machine. In other words, the idea behind these tools is to make your Mac faster for most tasks.

Let's take a look at each of them below:

Disk space analyzer

Units of measurement - MB (megabyte), GB (gigabyte), etc. - are used to let the user know the size of the files. This is because some people require a visual "quantification" of the space occupied in order to understand what is being used.

For example, it is important to show how much smaller a 200 MB file is compared to a 1 GB file. That's what this tool does. It analyzes the drive (or the selected folder) and visually shows the amount of space occupied for each file, folder or subfolder. See here for details as you can Clear System Data Storage on Mac.

This is shown in the panel in the right half of the window.

file shredder

This is a tool that the user must use very carefully. This "shredder", as the name suggests, completely erases files without any guarantee of recovery. If this is some important file for the application to work... you are lost!

BuhoCleaner itself recommends using this tool in the following situations:

  • When the user needs to erase sensitive data;
  • When you want to delete "persistent files" (those that can't be deleted in principle).

clearing RAM

This is RAM that temporarily stores data that the Mac uses to run programs.

That is, this memory is partially responsible for the speed of applications in the operating system. That is why the machine slows down when the RAM is overloaded.

This is what this tool promises to help solve. It is one of those that serve to make the Mac faster. BuhoCleaner recommends using this tool if:

  • Are you experiencing performance issues on your Mac?
  • The delay occurs when writing (you type text and it appears after a while);
  • Mac freezes for a while when loading applications or even web pages.

Reindexing Spotlight Search

Spotlight Search is a tool that the user activates by pressing command and spacebar to perform a quick search on Mac. This search scans both operating system files and the Internet to answer what you were looking for. And sometimes she gets into trouble.

The purpose of this tool is to solve problems with the functioning of Spotlight Search by rebuilding its index.

BuhoCleaner recommends that the user use this option if no results appear after a search and/or if the search tool is "behaving strangely".

clearing the cache

This tool also works in a similar way to clearing RAM. And it's also an opportunity to make your Mac faster. Basically this option clears IP addresses and other DNS records.

According to BuhoCleaner, among the problems that this tool helps solve are those related to security and internet connectivity. The program recommends using it if the user is having problems loading websites and/or connecting. To use it, just click on the "Start" button.

Shortly speaking...

It is an easy to use, understandable and very competent tool. It's not free costs 20 euros for life but it will come in handy ... in fact, for life. You can get 20% off when you use the coupon PPL20PT10valid for Individual Plan and Family Plan versions for the first 100 uses.

xrOS: Apple’s augmented reality glasses will get a new operating system



xrOS: óculos de realidade aumentada da Apple terão novo sistema operacional

fans Apple waiting for the launch of the headset augmented reality (RA) companies at the beginning of 2023 – in January, to be more precise; however, the change was revealed in an interesting detail. The tech giant announced that the hardware operating system will be called “realityOS‘, however the name will be xroOS, according to the latest reports. The effort invested by the pros has increased in recent months, indicating that the launch of the device is close.

According to recent announcements, Apple’s operating system for the augmented reality headset will be called xrOS.

One suggested reason for the name change is that the “xrOS” designation for international consumers will make it easier to identify the type of content that will be projected with the AR headset. Letters”XR” is an abbreviation for “andXcourted Rreality”, indicating the availability of resources possible with augmented reality, in free translation and interpretation.

Apple’s augmented reality glasses still don’t have a set release date

That is: based on the assumption that the equipment will play mixed content such as RA, as well as virtual reality resources (van), the consumer will be informed about what can be found easily. On the one hand, part of the intended experience is to combine real-time graphical information with the use of the environment and, at the same time, immerse the person in a differentiated experience with aspects of virtual reality, with a headset display.

The equipment will be able to play mixed content, such as AR itself, as well as virtual reality (VR) resources.

Because these approaches require powerful resources to run, despite being portable and lightweight, the hardware must also be powerful. Users will have access to new applications designed to provide unique experiences using product features. A wide range of options is expected, such as cards, messengers adapted for the mentioned technologies and much more.

Unfortunately, while the news was positive for those concerned, sources weren’t able to pinpoint the launch window. Therefore, many expect the presentation to take place in early 2023. Expectations are recommended to be controlled, because this is Apple’s first attempt in the segment, and unforeseen events may occur.

Portugal has been “sending” SMS for 27 years. Peaked in 2012



Portugal has been "sending" SMS for 27 years.  Peaked in 2012

The text messaging service, launched in 1995 in Portugal, peaked in 2012 with over 27 million SMS sent, and according to ANACOM data, that number has dropped to 10 million in 2021.

The world’s first SMS (Short Message Service) was sent 30 years ago, on December 3, 1992, by Briton Neil Papworth, a telecommunications engineer at Sema Group Telecoms, in the United Kingdom.

A Merry Christmas message was sent from Neil Papworth’s computer to Vodafone’s Richard Jarvis’ Orbitel 901 mobile phone.

The historic moment reached a new level in December 2021 when the first 15-character SMS was auctioned off as NFTs (“Non Fungible Tokens” or “Non Fungible Token”) for 107,000 euros during an event hosted by Aguttes in France. .

In Portugal, the messaging service was launched in October 1995 when TMN (currently MEO) and Telecel (currently Vodafone) were in the mobile carrier market, according to data sent to the Lusa Autoridade Nacional de Comunicações (ANACOM) agency.

In October 1995, Telecel first launched the feature for contract services that were not prepaid, a small percentage of the customer base, said Lusa Nuno Taveira, a former product manager for SMS and “messaging” at Vodafone.

One of the turning points in the development of SMS was in February 2000, when an agreement was signed between the three existing operators (after the introduction of Optimus in 1998, now NOS) allowing users to communicate between different networks, the regulator cites.

The first data available in ANACOM refers precisely to the year 2000, when the number of SMS reached 550 million, i.e. about seven SMS per active user per month.

The peak of SMS traffic was reached in 2012, when each effective user sent 180 messages per month, for a total of 27,860,126 messages.

However, according to ANACOM, this number is decreasing. In 2021, 68 SMS were sent per effective user per month (-62% compared to 2012), for a total of 10,729,392.

Another turning point for SMS in Portugal was the introduction of prepaid services, which allowed mobile services to become mainstream, said Lusa Teresa Salema, president of Fundação Portuguesa das Comunicações.

“We must remember that the mobile network first grows in higher segments. It was only after 1995, with the introduction of prepaid services, that we had a greater mass, and at that time, text messages also appeared with greater intensity and reached an absolute level. records,” he said, noting the arrival of the “famous MIMO developed at the time by Portugal Telecom in the laboratories of Aveiro.”

There are now more popular alternative ways to send messages, “instant messaging” such as Whatsapp or Messenger apps available for “smartphones” that combine text with the ability to send images, sounds, documents or popular GIFs.

In 30 years, SMS has had a peak in usage and is now in decline. But its use in advertising and marketing, from a security point of view, as an authentication factor or to create a particular spelling, such as using “k” to mean “it”, is a legacy that continues today.

However, the President of the Portuguese Communications Foundation stated that the technology currently available to the public involves the integration of several factors.

“There are three things that are needed because, in addition to the equipment, access to networks with the bandwidth and speed that we currently have with optical fiber or 5G is needed. And “cloud” (cloud). These are three things that we need to have the services that we have now,” he analyzed.

Teresa Salema, who worked at the Companhia Portuguesa Rádio Marconi in the early 1990s and has a three-decade career in the sector, also defended that technology exists to “improve the quality of life as well as the health of the planet.” .

While there are better ways to send messages these days, Teresa Salema points out that all technology eventually finds its place.

“The fixed network has its own space. And SMS also has its place,” he stressed.

In the case of SMS, its popularity and widespread use via mobile phones ended with another service that had gained relevance earlier: pagers or the “beep-beep” service, he recalled.

“Today, in our museum, we only have what a written message of this type looked like. It was almost like a telegram, so it was even shorter than an SMS.”

In addition, the Fundação Portuguesa das Comunicações, now 25 years old, has a dual mission of “preserving and displaying the entire heritage of the communications sector in Portugal” through the Communications Museum in Lisbon.

Teresa Salema said the history of communication is “much longer” compared to the decade in which SMS was born, and in Portugal it is “five centuries ago, in 1520, with the creation of the postal service”.

“At one time, King D. Manuel created a postal service specifically to support the Portuguese maritime expansion. Because, as is obvious, any economic development is based on a communication network,” he stressed.

The Museum of Communications now has an exhibition to mark its 25th anniversary where you can “touch and experience objects” of old and working technologies such as the typewriter, fax, telex and some GSM equipment, including Nokia co the famous game “Snake”.

To check for viruses, certificates from Samsung, LG and others were used.



To check for viruses, certificates from Samsung, LG and others were used.

Security certificates used by major smartphone and component manufacturers have also been used to sign at least 10 Android malware. Validators serve to ensure the authenticity of official software and operating system features, including access to restricted permissions that put users at high risk if misused.

The certificates of four companies were used irregularly: Samsung, LG, MediaTech and Revue. However, the total number of validators that raised the warning sign is higher, and the companies responsible for them cannot be identified; Similarly, it is not known exactly what led to the compromise of these elements, which could be obtained as a result of leaks, intrusions into internal systems, or even the actions of malicious employees.

Be that as it may, the following packages related to malicious applications have been found to be dangerous and use illegitimate certificates:

  • com.russian.signato.renewis
  • com.houla.quicken
  • com.attd.da
  • com.arlo.fappx
  • com.metasploit.stage
  • com.vantage.ectronic.cornmuni

According to the Android Vulnerability Partners Initiative (AVPI) report, the use of such certificates by applications can grant them privileged access to smartphone data, as well as block functions such as intercepting and making calls, collecting information, and downloading or deleting other applications. . Essentially, the validator gives the software the same level of control as the owner of the device itself, if not more, allowing it to launch targeted and destructive attacks.

Although no specific campaigns were identified, the certificates were present in software that contained Trojan horses, displayed inappropriate ads, stole data, or delivered viruses. However, according to Googlewhose researcher Lukasz Severski of the Android security team was responsible for the detection, there is no indication that the malicious apps were present in the Play Store, ultimately reducing the scale of the attack.

The report was only released now, after the manufacturers were notified so that the certificates could be updated and the versions used by the attackers are no longer valid. Meanwhile, Google indicates that it has recommended that all affected companies immediately investigate the causes of the incident, as well as reduce the number of signed applications and resources in order to deter this type of misuse.

End users are also protected from further exploits even if they have downloaded malicious apps on their smartphones. Since the certificates that would guarantee fraud no longer work, they cannot work, with the usual recommendation to only download software from official sources, accompanying a warning, as a way to minimize future risks.
