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.).

I had Docker Desktop installed for Mac Catalina last year, but I haven't used it until today, a day after updating to Monterey (from Big Sur) (I'm on a Mac Intel) when I downloaded the latest Docker Desktop dmg file (~500MB), which had me drag the icon to the folder, which I then chose to replace the existing .app file... but when opening the file (in /Applications), I get this new pop-up:
I've tried to search what this is actually going to do, and I can't tell; I use Cisco AnyConnect VPN sometimes for a project, and I'm afraid there'll be a conflict... but ultimately, I don't know what exactly I'm giving access to or if it's actually necessary. I just want to try Docker with Laravel Sail.
I know macOS over the last several years (since Catalina really) has changed filesystem stuff a lot and I end up going down StackOverflow rabbit holes trying to get things to work, so I'm hoping someone else knows how this works or has made it work and can advise.
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.
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.
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.
I recently updated my MacBook Pro (2.3 GHz Intel Core i5) from Lion to Mountain Lion and simultaneously upgraded Xcode to the latest 4.5 version. I've experienced one very irritating problem. While programming I'm used to have a couple of tabs opened at a time. Ever since I updated, each time I switch tabs, Xcode freezes up for a bit (a couple of seconds). Does anyone have a suggestion to solve this problem?
I followed a tip on deleting project.xcworkspace to improve performance. Which seamed to help, but only for a short period of time.
It's a common issue and was fixed in XCode 4.5.1.
https://devforums.apple.com/thread/167765?tstart=0
If you have multiple partitions (maybe a backup of Lion was kept) ensure that xcode really comes from the Mountain Lion partition.
The App Store App update for Xcode seems to take the first Xcode.app it finds and will apply any update to that version. In my case it updated the (inactive) Lion partition, even so I booted from the ML partition.
xcode-select did not complain when I tried to change it to the ML version.
So I ended up doing the great housekeeping:
do a chmod 000 /Volume/<old Lion partition>/Applications/Xcode.app
installed a fresh copy on Xcode.app into /Applications
verify the destination of the dock icon (must point to the ML Xcode.app)
My Xcode is now fast as before and it remains fast. You can get the Xcode dmg and the command line tools from https://developer.apple.com/downloads/index.action. I don't think there is a difference in the binaries, but with the DMG I could see where I dropped the Xcode.app.
I found your question before I discovered a partial solution.
As of today, I find XCode 4.6.1 GUI dog slow for my taste, specially considering that I run on a one year old mac, SSD, compile to a 2GB RAM disk and still have 6GB RAM left. Even Eclipse runs lightning fast compared to XCode
4.5.1 did improve something, but after a long time using XCode I do not have any hope for some of its problems being solved ever.
That being said, I have noticed that "Live issues", the main tool bar and all the panels slow down tab switching to same degree. The biggest offender so far are the navigator panels.
Once I got used to a minimalistic Xcode window, layout some specific task tabs, keep a separate window for xibs and learned the shortcuts to enable/disable the panels, I no longer suffer so much with XCode responsiveness, but there is still some lag that can be clearly felt.
Check that there is not heavy coding on ViewWillDisappear.
Also if you have NSURLConnection or any other having delegate methods should not get called while switching tabs.
