Unable to uninstall app consuming lot of memory - macos

I am using MacBook Air with Catalina OS. When I hit top command it shows an app Electron consuming about 50% RAM.
I tried uninstalling it but can't find in application list. I have not installed this Electron app explicitly and don't know how it came on my machine.
How to uninstall this as I am not using it?
Top command output:

A quick search shows that Electron is a framework on which google chrome (to name one) runs. So you cant really uninstall it, however you could try, closing a few chrome windows or tabs. A blog gives a solution to this issue by replacing Electron apps as a whole (like using safari instead of chrome), which is not an option for everyone but is worth considering.

Personally my advice would be to upgrade to Mac OS Big Sur(if your mac is supported) as I experience some performance increase and found that it was generally more optimised.

Remote Desktop for Mac - issue with JavaFX app - PDFBOX

I have written a JavaFX app running on Windows 10 machine in the office which has problems showing (painting/rendering) certain embedded controls such as a Pane with PdfBox when I connect to it with Remote Desktop for Mac. It shows only a black screen in the app instead of the pdf document.
When I connect using RDP from my Windows 10 machine at home to my Windows 10 machine at work, the app works just fine (the pdf is shown in the app).
I have the same problems using AnyDesk and Teamviewer.
The app only shows PDFs properly using a connection from Windows 10 to Windows 10 with Microsoft RDP.
It might be a JavaFX issue. Similar issues are described here (although not 100% identical):
https://bugs.openjdk.java.net/browse/JDK-8239589
https://bugs.openjdk.java.net/browse/JDK-8229394
However, since I guess Microsoft Remote Desktop for Mac is using the same technology as the Windows Desktop client, I would have expected it to work fine.
I have a Mac Mini M1 running the latest OS (Monterey) at the time of writing this post. I am also using the latest Remote Desktop client for Mac.
This problem is not new and was also present in older releases.
I have tried to play around with screen resolutions, both on Host and Client but nothing good came out of those tests.
Disabled also hardware acceleration in Remote Desktop for Mac preferences but it didn't change anything.
The machine at the office has the following specs (which I cannot change nor update)
Edizione Windows 10 Pro
Versione 20H2
Data installazione: ‎10/‎09/‎2021
Build sistema operativo 19042.1415
Esperienza Windows Feature Experience Pack 120.2212.3920.0
Anyone else who has seen this problem and perhaps resolved it?
Could it be a bug in either PdfBox or Remote Desktop for Mac?
Except for the above issue, the Remote Desktop Client for Mac is working great (not lagging as TeamViewer or AnyDesk) and the user experience is phenomenal.
PS: While this might be considered a programming question (since I wrote the app with JavaFX) but it might be better to post on another forum? If yes, which one? On the other hand, many similar posts (look at the suggested thread on the right) have been upvoted despite not dealing with programming issues.
Thanks.
How do you use PDFBox? I ask because this is not a JavaFX component. If you use a SwingNode for that it might be interesting to try one of my two PDFViewer demos here and see whether the problem persists.

The difference is in how I do the rendering and maybe that makes a difference for your use-case too. But of course this is just a wild guess and I can't promise anything.

How to install XCode 9 GM on MacOS Sierra 10.12?

I actually built a Hackintosh to learn programming with Xcode. It runs on my Asus X555LA laptop. I downloaded the latest Xcode 9 GM build from the Apple Site (not from App store). After extracting, when I tried to install, it shows "You can't use this version of the application "Xcode" with this version of macOS; You have macOS 10.12. The application requires macOS 10.12.6 or later".
Is there any tweak to make it run on my Sierra 10.12 itself? I can't really think about upgrading the macOS version as it's a Hackintosh. I followed this guide to install macOS on my Asus laptop.
Xcode requires latest macOS, you have no choice, you need to upgrade the macOS version on your Hackintosh. Or better: Reinstall macOS in a recommended way on your PC, if you're doing Hackintosh... :)
The guide you linked is very poor... Never use premade install images, because these have been modified in an uncertain way, and you don't want to install a premade undocumented mess to your computer. It might be packed with threats, malwares, spy tools and so on.. It's the worst thing I can imagine in security aspect to install an OS image from uncertain source.
Also, there is no universal macOS installer for PCs - even though many are trying to find a way to create it: it's a bad idea and it will never succeed because there are so many PC parts, millions of differently built computers..
The only way to create a stable fully functional Hackintosh is to know your hardware and create an installer flash drive for that specific PC. First you have to download the latest macOS Sierra from AppStore, this is the only source that you can trust, because it's downloading from Apple's servers. Then install a small program, called Clover bootloader to the flash drive to make it bootable.
This is the only full and up to date guide for PC laptops. If you have questions, register to the linked site and start a new forum thread posting your questions. They will help you but please read this guide at least 3-4 times carefully because everything is described here.

Unable to install Xcode 8.1 on my Windows 10 computer

I've been trying to download Xcode but when I open it nothing happens.
Xcode_8.1.xip
Do I need to us using a Mac to be programming for iOS? I am currently using Windows 10.
Simply, yes, you need to have a Mac, or some other macOS running computer to run Xcode. But...
There is a way to run Xcode on Windows, however it's a bit of work. You can follow a tutorial on the internet like this one to get Xcode working on Windows.
Let it be known that even though Xcode will run on Windows using this, it is definitely not good in quality compared to on a Mac, as there will be lag and unnecessary difficulties that wouldn't be there on Mac.

Appcelerator Studio is very slow when scroll

Appcelerator Studio, build: 4.7.1.201609100950
macOS Sierra 10.12
iMac (Retina 4K, 21.5-inch, Late 2015)
Java 8
Node.js 4.4.7
npm 2.15.8
Titanium CLI 5.0.9
I've tried (many times) to reinstall the editor, but without solving the problem. The editor is really really slow when scroll (after macOS Sierra update). It's impossible to use it without going crazy. I use Appcelerator Studio for many years and i have never had these problems.
There are other external components that could upgrade / reinstall? (Java.. etc etc)
Thanks
Update
In addition to the slowdown, the editor does not properly recognize the file format.
I had this slow down issue with appcelerator Studio as well (some of my colleagues swear by using Atom editor)... this happens with Appcelerator when you have one .js file that is huge (thousands of lines).
Ideally, split your js file into seperate commonJS files and coll them into the original js file with require('filejs')
I also had this problem for almost 1 month and I went completely crazy one day due to Studio slow-ness.
I tried complete fresh installation of Appc & all of its components 2-3 times, but no luck.
Then on one day, it was not working even like previous day, so I decided to completely format my MacintoshHD and re-install the macOS Sierra because I noticed that some other normal apps like Skype & Email were also started working slowly. So I got the idea that it's related to macOS Sierra update.
Very Important Note (take system backup first)
Before installing OS, I took backup in external hard-drive and then I ran the First Aid (Disk Utility Tool) on MacintoshHD and found that there were some corruptions in it, so I fixed them but then something really crazy & out of this world happened with my system - Kernel Panic and my system did not start-up for 3 hours of hectic try.
So the last solution was to format the Macintosh HD & install the OS again. The best way to do this is to make a bootable pen-drive having macOS Sierra in it and then install using it.
Another way (if you have very good speed LAN) is to connect your system to Apple server and let it install latest OS from online. But it will download the whole OS & other required files (of at least 5GB size).
There are many online tutorials on how to install macOS Sierra again after such creepy issues.
FYI: I did re-installation of macOS Sierra last week & now everything is working like it is supposed to work on a Mac machine (just buttery smooth.).

How to instal libgluezilla for MAC OS X

I am trying to run a Mono application on the Mac that has an embedded web browser control. The program runs, but now broswser is show and a message is output:
libgluezilla not found. To have webbrowser support, you need libgluezilla installed
I have searched, but have no idea how to install this. Your guidance would be appreciated.
You cannot use the embedded web browser control on Mac. Hence, there is no libgluezilla for Mac.
It worked in 2.4.2 of mono, but not with the latest patch. ( 2.4.2.1 )
I am loosing patience with mono on mac platforms. Things used to work and then stop working, creating a bugzilla entry gets no responses at times.
