How can I Totally remove Plex Media Server for Mac?

Have you ever met the problem not to able to remove Plex Media Server for Mac successfully?  Now I’m here to share what I’ve got in the idea to completely uninstall it in complete steps & tips.

“I sampled many of these programs, and now I want plex gone. Using synaptic, I uninstalled the plex media package, but anytime I resume from standby, I can see in the black/white command window (the one that shows when a pc is booting) that "plex-media-server" is starting or stopping. I want it gone; how would one go about doing this?”
“I tried to uninstall the Plex Media Server plugin. I got an error as follows. The Plex Media Server still shows up on my Services list. But it is no longer showing in the Plugins tab. I've tried removing and adding the Plex repository but that hasn't helped.”


Plex Media Server is a software program developed by Plex. The most common release is 0.9.728, with over 98% of all installations currently using this version. It adds registry entry for the current user which will allow the program to automatically start each time it is rebooted. A scheduled task is added to Windows Task Scheduler in order to launch the program at various scheduled times (the schedule varies depending on the version). The software is designed to connect to the Internet and adds a Windows Firewall exception in order to do so without being interfered with.

iPhone 8S Model Rumors Launch in Three New Colors, Blue, Yellow, and Pink

In recent rumors, Apple is expected to launch three new iPhone models in 2018 – a successor to the iPhone X, a larger Plus version, and a more affordable LCD model with a similar, bezel-less design. For now, it's called the iPhone 8s or known as the iPhone 9.

Rumors about the three versions have been floating around since last year — about the designs, displays, cameras, and hardware of the phones — but it was only recently that we began hearing about some new colors, the phonearena said.

The much “cheaper” LCD model of iPhone will also remove 3D Touch function in the future, according to the report.

Apple is likely to target the young consumer market with a range of colors, including blue, yellow and pink, for the cheaper iPhone, saying in a report of Jun Zhang, who is an analyst of Rosenblatt Securities, earlier in May.

"Since Apple start to launch three new models every year, we believe the company needs to differentiate the designs of the LCD model from the two high-end OLED models. One reasonable choice would be to add different colors."

iOS beta 6 comes out soon after the release of beta 5

Three days ago Apple rolled out the 5th beta of iOS 11.4, and then on this Thursday it seeds the beta 6 to developers. Two betas in one week? One guess is that the official version of iOS 11.4 will be coming soon. And possibly it might be the last version for iOS 11. After all, the WWDC 2018 event will take place during June 4-8 in San Jose, California, in which we will see the announcement of iOS 12 (and also macOS 11.14).

Another possible reason for this quick release could be that there exist bugs/issues in the previous beta that need to/can be corrected as soon as possible. Earlier this week, a vulnerability dubbed EFAIL was revealed by security researchers, and the HTML rendering flaws discovered in Apple Mail for iOS and macOS allow attackers to reveal the plaintext of someone’s encrypted emails without the encryption keys.

Anyhow, let’s review what new features and improvements iOS 11.4 introduces. First of all, iOS 11.4 adds the Classkit framework.

This feature was spotted in the beta of iOS 11/3 and then launched as part of iOS 11.4. Developers can integrate this framework with their education apps to add more features, while teachers can assign tasks through Schoolwork and keep track of student progress in those 3rd party apps.

Apart from the new Classkit, iOS 11.4 pulls back some features, which was introduced in the betas of iOS 11.3 but disappeared in the official version of iOS 11.3. For instance, the support for Messages on iCloud. Previously, you are not able to check the old messages in new devices or sync the deletion of one device to other connected ones. Now the Messages in iCloud feature allows users to download all iMessages on new devices and the deletion will sync on all connected devices. Storing all messages and attachments in iCloud can save the device’s valuable storage space.

There is also a long-awaited features: AirPlay 2. It allows one single source to send audio to multiple speakers that support AirPlay 2, including Apple TV and HomePod. With AirPlay 2, you can ask Siri on your iPhone to control the audio content playing on separate devices in multiple rooms. As for the HomePod stereo support, it was added in the first beta of iOS 11.4 but removed in the second beta for somehow.

Besides, iOS 11.4 also contains a new security feature called USB Restricted mode. This feature is probably designed to prevent authorized third parties (like the GrayKey box) from physical accessing to data stored in iPhone via USB cable.

Mac Tricks: Convert Color PDF Files to Grayscale/B&W

There are some occasions that we need to convert a color PDF file to black and white. For instance, a PDF file that contains many color images may be quite large in size and you wish to reduce the size by converting it to the gray version. Other reasons for the conversion could be the attempt to save colored ink, or to verify how the PDF file looks in grayscale before putting it in the printing procedure.

To achieve the conversion on a Windows PC, you have to utilize standalone programs like Adobe Acrobat Professional, third party plugins or some free/paid online websites, while on a Mac computer, things become much easier: you can use the built-in Preview app to add effect on a PDF, or change colors by applying a sepia tone on it.

Have no idea how to remove Adobe Acrobat Pro after it is expired? Get help here.

  • Open a PDF in Preview, and choose File > Export from the menu bar on the top.
  • As the Export dialog box appears, you can type a named in the Export As field for the PDF file, add tags if you like, and specify the location you want to store the file.
  • Choose Gray Tone (or Black & White) from the drop-down menu of Quartz filter.

After all these configurations, click Save button to export the file in target location. The saved PDF file should be stripped of the colors except the one(s) you choose. Generally, the gray version may be more comfortable in visual than B&W version. And it’s notable that depending on the content and layout of the original file, the newly created one may not look exactly the same as it has not be converted before. Next time you would like to print a color PDF file in black and white, you can apply this trick to finish the conversion and check the effects before sending it to the printer.

By the way, if you need to convert PDF files on a frequent basis, you can take advantage of the built-in Automator app to create an automatic workflow, which will help you expedite the job. Wanna know more about this trick? Read on please.

  2. Choose workflow as the type for the document, and click Choose button below.
  3. On the left pane of the open window, click Files & Folders under the Actions menu, and drag Ask For Finder Items from the sub-menu to the blank space on the right side.
  4. Again, drag the Copy Finder Items option to the right pane below Ask For Finder Items. Then assign a folder in the To drop-down menu as the destination converted files. And you can choose to whether check the Replacing Existing Files option or not. 
  5. In the PDFs sub-menu, drag Apply Quartz Filter To PDF Documents to the right below Copy Finder Items, and choose Gray Tone from the Filter drop-down menu.
  6. After the customization, head to the File > Save in the menu bar on the top.
  7. Type a name for the customized workflow, and save it to the Applications folder.
