“In order to continue the installation, please close the following application: iTunes” : Xcode Menace


Just when I thought everything was alright…I got “In order to continue the installation, please close the following application: iTunes” and it was showing after it completed almost 97% of the installation.

Yes….I was trying to install Xcode 4.1 into the Snow Leopard…
Developing app for MAC is something I always wanted to do,and now when I was just going to utilize my Apple Developer membership this stupid error cropped it's head.



I checked the dock bar, and iTunes wasn’t running at all. I also have an app called QuitsAppsMBI which is a handy tool for quitting applications, nothing on there to say iTunes was running. Lastly, I checked Force Quit to see if there was anything, and there was nothing in there at all.


Not wanting to potentially ruin the installation, I wasn’t sure I wanted to just kill the Installer, so I seeked the help of Google to see if there were any suggestions on what to do. I came across the following post on James Greenhalgh’s blog: http://james.greenhalgh.eu/2011/in-order-to-continue-the-installation-please-close-the-following-application-itunes

This post detals exactly the problem I was having, and a really simple fix! Open up Terminal (found in Applications\Utilities) and type in the following command:

ps x | grep iTunes

This will list all the processes running on your computer with iTunes in the path. This returned the following for me:

189  ??  S     0:00.04 
/Applications/iTunes.app/Contents/MacOS/iTunesHelper.app/Contents/MacOS/iTunesHelper -psn_0_57358
2613 s001  S+     0:00.00 grep iTunes

So this shows that the iTunes Helper is still running in the background. To kill this off, you then enter the following command:

kill 189

The first number from the first command is a process ID, so you’re telling it to kill the process with ID 189. Change the 189 to whatever the ID shows as from the first command, and it’ll end the iTunes Helper. After a few seconds, the Xcode installer will clock onto this and continue the installation!

ARCore and Arkit, What is under the hood: SLAM (Part 2)

In our last blog post ( part 1 ), we took a look at how algorithms detect keypoints in camera images. These form the basis of our world tracking and environment recognition. But for Mixed Reality, that alone is not enough. We have to be able to calculate the 3d position in the real world. It is often calculated by the spatial distance between itself and multiple keypoints. This is often called Simultaneous Localization and Mapping (SLAM). And this is what is responsible for all the world tracking we see in ARCore/ARKit. What we will cover today: How ARCore and ARKit does it's SLAM/Visual Inertia Odometry Can we D.I.Y our own SLAM with reasonable accuracy to understand the process better Sensing the world: as a computer When we start any augmented reality application in mobile or elsewhere, the first thing it tries to do is to detect a plane. When you first start any MR app in ARKit, ARCore, the system doesn't know anything about the surroundings. It starts pro

ARCore and Arkit: What is under the hood : Anchors and World Mapping (Part 1)

Reading Time: 7 MIn Some of you know I have been recently experimenting a bit more with WebXR than a WebVR and when we talk about mobile Mixed Reality, ARkit and ARCore is something which plays a pivotal role to map and understand the environment inside our applications. I am planning to write a series of blog posts on how you can start developing WebXR applications now and play with them starting with the basics and then going on to using different features of it. But before that, I planned to pen down this series of how actually the "world mapping" works in arcore and arkit. So that we have a better understanding of the Mixed Reality capabilities of the devices we will be working with. Mapping: feature detection and anchors Creating apps that work seamlessly with arcore/kit requires a little bit of knowledge about the algorithms that work in the back and that involves knowing about Anchors. What are anchors: Anchors are your virtual markers in the real wo

Road to the Grant : Immersive Payment

  This is a news close to my heart. My project "Immersive Payment" has been awarded with Grant for the Web , and I will be focusing on using Web Monetization to enable Micro Payment and for Web Mixed Reality assets, as well as for 3d contents. It took me almost five months from learning about the initiative to actually getting thee Grant. It all started back when in Mozilla TechSpeaker call a fellow TechSpeaker and a friend Andrzej Mazur explained bout the program. He himself is also an early awardee . After the talk, I got really excited and interested in the potential and concept of Web Monetization, however, it wasn't until June that I really decided to apply. The application process was a bit of roller coaster ride for me. I had an idea of what I wanted to do and also explored what is possible right now. But a bit of termoil in my personal life kept me from going beyond toy implementations. Fast forward to June end and I finally had the project chalked out with init
