Steps to clear all user log files on Mac


The logging system of macOS is very elaborate that i can monitor and log various system level and app level functionality, including app crashes, problems, and internal errors with apps.

Here you can learn how to access the raw log files and clear these user level logs from your Mac. But this is aimed at advanced Mac users instead of the average or novice users.

To be perfectly clear, these logs are almost entirely crash and error logs for particular apps. Despite what some third-party utilities may claim, removing user level logs is not a necessary task and nor should this be encouraged.

How to clear user logs from macOS

You’re suggested backing up your Mac before doing this.

1. From the Mac finder, pull down the “Go” menu and select “Go to folder”

2. Enter the following directory path exactly, including the tilde:


3. Selectively choose the logs you want to inspect or delete, or alternatively you can select and trash them all


4. Empty the Trash

Please note that you may not restore any meaningful disk space by deleting log files, which may take up just a couple of megabytes or maybe even just kilobytes. And doing this will not speed up your Mac.

Feature of Office was designed on Mac


In Windows, Clippy can help PC users with their Microsoft Office software. Despite it’s meant to be good, it’s not favored by everyone. “You’re writing, need some help?” This prologue of Clippy is the biggest reason that Microsoft Office users don’t like it.

Since 1997, we could see Clippy automatically appear in Microsoft Office, until 2001, it’s no longer a default feature of the software. Microsoft even made fun of Clippy in the ads of new Office software to emphasize the convenience of their new product. In the 2007 version and higher, Microsoft Office has completely terminated the Clippy help system.

Recently the designer of Clippy, Kevan Atteberry, mentioned this work in the interview of Motherboard, retrospecting many interesting things and the process of designing Clippy back in the old days. He said there were 250 designs to choose in total, and Microsoft, designers and social psychologists of Stanford University together made the decision of choosing his design. None of them thought it would be disliked by users.

But the most unexpected is that since Clippy was chosen, Atteberry never saw it himself. You might have guessed it: Atteberry designed Clippy on Mac, which he works with all the time without using Windows, so he hasn’t gotten a chance to see Clippy.

iOS 10.3.2 beta 3 released to continue fixing bugs

Days ago Apple has rolled out macOS 10.12.5 beta 3, watchOS 3.2.2 and tvOS 10.2.1 for developers. This update is still mainly for fixing bugs and improving device stability & security.


iOS 10.3.2 beta 3 doesn’t have anything new either but bug fixes and performance improvements mainly.

Without any important new features added, MacOS 10.12.5 beta 3 fixed some issues found in macOS 10.12.4, which was launched on March 27. Surely macOS 10.12.5 will continue improving stability, compatibility and security of Mac devices.

Apple last month has brought us macOS 10.12.4, but quite a number of users said it negatively effected the sound quality of USB headset, causing staccato, distortion, etc. Some said the newly installed macOS 10.12.4 can’t fix the problem, only restoring to macOS 10.12.3 or lower does. Hopefully this version can solve that.

In macOS 10.12.4 Apple for the first time adopted Night Shift, meanwhile PDFKit API has been improved, and brand new data statistics have been added for iCloud.

Apple released update for Final Cut Pro X and iMovie

Service industry has become more and more important to Apple, who has been improving their apps for us. Now, the video edit tool Final Cut Pro X and iMovie has released by Apple.


This update for Final Cut Pro X allows users to choose more colors for character editing, change the width while adjusting effect parameters, and run Canon Log 3 and Sony S-Log3 / S Gamu3 log processing. And DVD creation is another important feature – for instance, we can improve the fonts and have better image quality in menu and sessions.

This update also fixed some bugs and problems in older versions.


The iMovie update is basically a maintenance version, addition to the improvement of performance and stability, it also fixed the bug that videos imported from some camcorders may be displayed in light-red tone and some videos shot by some iPhone can’t be seen in the import window.

With this latest version you can have the most powerful combination of Final Cut Pro X – newly designed interface and the focus on your videos. It will be a good match with both Final Cut Pro X and Macbook Pro.

Skype for Mac 7.50 update: easier for sharing


Skype for Mac 7.50 has just been released. It supports macOS Share extensions, letting users share files, videos and photos more conveniently.

Microsoft said Skype for Mac 7.50 supports Share extensions on macOS 10.10 and higher. Users can directly share files on Skype by selecting them, clicking “Share,” and clicking “Skype” in the menu.

After updating to version 7.50, users can open Skype through Preferences > Extensions > Share Mnue, and use the features.

Last month for MacBook Pro users Apple has added a new feature in version 7.48: Touch Bar support. With Skype 7.48 users have more convenient control of calls. And through Touch Bar, users get to see the object’s name & avatar image and start a video call, the Silence and Hang on buttons are both bright red. Touch Bar has other regular buttons including adjustment for brightness & volume, Siri and Exit.

Skype for Mac 7.50 improves both its performance and stability.

What to do if Share options are missing?

Many users said after they updated to macOS Sierra 10.12, AirDrop and some other options can’t be seen sometimes. Fortunately someone has found a solution, which was tested to be effective.

If your Mac device encountered the said problem after the system was upgraded to Yosemite El Capitan, try the following solution:


1. Open the Terminal app, which is in the Utilities folder of your Applications folder.

2. Type this command in Terminal:
/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -seed

3. Press Return and wait for the Terminal prompt – which ends in $ – to reappear. It may take a few minutes.

4. Quit Terminal.

Then you should see the previously missing options, such as AirDrop, Email and Share on Facebook, etc. If not, go to Apple menu > System Preferences, click Extensions, and make sure that the Markup and sharing features are turned on in the Actions and Share Menu sections.

WikiLeaks: Apple macOS used by CIA

Previously WikiLeaks discovered that iOS vulnerabilities can be used by CIA for monitoring. WikiLeaks threatened Apple that if they doesn’t fix this problem, there will be consequences. Before any responses came from Apple, we learned new reveals already – according to WikiLeaks, not only iOS, but also macOS, which has the vulnerabilities that can be used by CIA.


Compared to iOS, macOS seems to be less risky though. WikiLeaks pointed out that CIA mainly uses Thunderbolt EFI vulnerabilities in Mac apps, and reboot won’t make them gone. WikiLeaks, however, also found out during tests that reinstalling the system will block the vulnerabilities, meaning hardware update will permanently fix them until the next infection.

When WikiLeaks newly exposed the problem, Apple has responded that more than 80% of the vulnerabilities were fixed through the latest update, and their engineers had been working on fixing the rest. For that, Julian Assange, founder of WikiLeaks, said they would like to work with Apple, providing information of the vulnerabilities they discover, so that Apple can resolve them with much higher efficiency.

Pwn2Own hacking competition: macOS & Safari attacked

The 17th annual CanSecWest conference was held in downtown Vancouver, researchers were competing for the tenth anniversary reward over $1,000,000 of Pwn2Own.


The Day 1 result has been put on Zero Day Initiative as well as part of the Mac vulnerabilities in the achievement list.  Independent hackers Samuel Groß and Niklas Baumstark successfully acquired the root-access privileges through Safari vulnerabilities on macOS, and display rolling messages on MacBook Pro’s Touch Bar. That helped them win the a reward of $28,000.

On the same day, security inspection lab Chaitin also broke through Safair and obtained root-access privileges on macOS. They found 6 bugs during the crack, which won $35,000 for them.

On Day 1 all the competitors won $233,000 in total, including a $105,000 reward won by Tencent Security team. Other cracked software: Adobe Reader, Ubuntu Desktop and Edge for Windows.

Apple used to send representatives to participate the Pwn2Own competition. Influenced companies will find their security vulnerabilities and fix them asap.

Apple reveals first public sign of macOS 10.13, what will it be called?


Eagle-eye blogger Pike’s Universum has discovered what appears to be Apple’s first public sign of macOS 10.13, while the next major version of macOS likely won’t be announced until WWDC 2017 opening keynote on June 5.

Specifically, the blog shared a portion of App Store URL, also known as a CatalogURL, for macOS 10.13. It appears to be a secure HTTPS link originating from Apple’s servers, although the screenshot can be forged,  the blog has been providing reliable information, so we think the screnshot should be legitimate.


We don’t know much about what’s coming in macOS 10.13 at present, but since the beginning of the year, there have been more and more devices running macOS 10.13, presumably as Apple’s engineers work on the operating system update ahead of its unveiling.


We don’t know what the successor to macOS Sierra will be called, yet in 2014, Apple trademarked a long list of names, which range from popular beaches and well-known cities in California, where Apple is headquartered, to mountains, deserts, and animals.

A list of known trademarked names that have yet to be used: Redwood, Mammoth, California, Big Sur, Pacific, Diablo, Miramar, Rincon, Redtail, Condor, Grizzly, Farallon, Tiburon, Monterey, Skyline, Shasta, Mojave, Sequoia, Ventura, and Sonoma. An entirely different name is certainly possible too.

Chrome users on macOS get enhanced safe browsing protection

macOS is a rock-solid desktop operating system thanks to its Unix foundation. While it’s not infallible, there are far fewer malware threats for Apple’s operating system compared to Windows 10. As more and more consumers buy Mac computers, evildoers will have increased incentive to write malware for macOS.


Fortunately, macOS users who choose to use Google Chrome for Internet surfing will be safer, as a few days ago the search giant has announced to improve its safe browsing initiative to better warn users of malicious websites and attempts to alter browser setting. .

“As part of this next step towards reducing macOS-specific malware and unwanted software, Safe Browsing is focusing on two common abuses of browsing experiences: unwanted ad injection, and manipulation of Chrome user settings, specifically the start page, home page, and default search engine. Users deserve full control of their browsing experience and Unwanted Software Policy violations hurt that experience,” says Google.

The search giant further explains, “The recently released Chrome Settings API for Mac gives developers the tools to make sure users stay in control of their Chrome settings. From here on, the Settings Overrides API will be the only approved path for making changes to Chrome settings on Mac OSX, like it currently is on Windows. Also, developers should know that only extensions hosted in the Chrome Web Store are allowed to make changes to Chrome settings. Starting March 31 2017, Chrome and Safe Browsing will warn users about software that attempts to modify Chrome settings without using the API.”
