Upgrade to macOS Sierra

When I started my Mac today, there is notification to install brand new OS from Apple, the macOS Sierra. I a bit doubt to install, thinking that there are apps that I use every day might wont work. But I finally decided to take the risk, I clicked the install button.



Installation process went very smooth, it looks that the setup files already downloaded. It took 30 minutes to complete the setup.

Everything looks okay. All basic apps work. The only problem I found so far are:
1. Adobe Photoshop, GIMP might not work. Sierra tells me that in order to run this app I need to install Java 6, which I think, as far as I remember, already installed in the previous OSX Yosemite. I will check this later.
2. Remote drives that I setup on Ubuntu via AFP does not work. Sierra asked my to enter password for AFP connection, so I entered the password, no incorrect password message, but all drives are not mounted. There is a question mark icon on the Ubuntu server in Finder. I don't know what it means yet. I also found that the status is "locked".

A quick opinion after installation, I didn't see any different in user interface, it looks and feel the same with Yosemite. I am expecting a new cool user interface from this new OS. Few things that I can't wait to test new features from macOS Sierra, which I think will be very useful, such as Siri, and sharing files and folders with other devices.

I you experienced same issues above, please share how you solved them. I will share as soon as I got the solution as well.

How to connect USB 3.0 + USB 2.0 Y-cable?

The question above is burning in my head, and when I google it, I couldn't any satisfying result to my question. I even couldn't find the right image of the USB Y-cable in the search result. See the cable picture of the Y-cable below.



In this article I hope can answer the question and let you know its purpose and how to use it.  In my case, I use it to connect a Prolink PUH302 USB3.0 4-Port Hub. It comes with the USB 3.0 + USB2.0 Y-cable. In its limited documentation which only available in the outer box, shows single wire USB cable which is different with what I got.



When you connect a device (like the Prolink PUH302 USB3.0 4-Port Hub)  to a USB port on a computer system, this device is drawing power from the USB port to power the device. If the device draws too much power from the port and the port cannot provide enough power to the device, the device may not work correctly or may exhibit symptoms like random disconnection, device/drive clicking noise, device not detected, file transfer problem, device will not spin up and more.

One way to provide more power to the device is to use another USB port to help supplement the needed power for the device.

What we have done is use a regular USB cable and adds another USB connector to the end that plugs into your system. It looks like a Y cable. The two tip of the Y-cable are the two type A USB connector connecting to two USB port on your system and the other end to the device (USB hub device). You will notice on the Y cable, one of the type A connector will have a cable that is thinner, that is the supplemental USB power connector.

HOW TO USE THE Y CABLE

First connect the connector to the enclosure then the thick cable with the USB header to your system. If you notice problem symptom listed above, please connect the supplemental USB connector to another USB port on your computer.

QUESTIONS:

1) If I am using USB 3.0 device and port on my system, why do I still need a USB Y cable, since I know my single USB 3.0 port do provide enough power for my external drive?
The USB 3.0 Y cable actually serve two purposes, if you are using it with a USB 3.0 port on the system, you will only need a single port or connector. You do not need to use the supplemental USB connector. If you do not have access to a USB 3.0 port, this USB 3.0 Y cable will function just like a USB 2.0 Y cable and allows you to connect your external drive to the USB 2.0 port on a non USB 3.0 system and still have access to you data.


2) Will using both connectors on the Y cable overload and hurt my drive?
No, it will not. It is safe to use with both connectors.


3) Can I use only the thinner cable?
No, the thinner supplemental connector is only for power and will not provide any data signal.


4) I am connecting my external enclosure using eSATA connection and I also need to use both USB connectors of the Y cable?
You MAY need to use it IF the external enclosure draws too much power from one port. By using the main with the supplemental connector, it will have enough power to power the device correctly

After upgrade to OSX Yosemite, all vbox instances stop working. Simple solution for this problem is to upgrade your Virtual Box to version 5.

Download the latest version 5.02. Open the package, and start the upgrade process. You don't have to change any settings from previous version. It will work like a charm.

Upgrade to OSX Yosemite


As soon as its announce that OS X Yosemite is launched, I immediately do the upgrade last night. It took almost 15 hours to download. This morning I completed the installation. Everything looks fine. Then I also do some applications upgrade. I saw 7 apps need to upgrade in App Store.

My first impression on the UI is mixed, exited because its brand new OS X, but feel uncomfortable with the new font, buttons, new colour used, imperfection on icons and some new small changes on layout. The feel is different. I've been using Mac OS since its first version, this is the first time I have different feeling.

Most annoying is my network drives are somehow not working. It always worked in the last couple upgrades without changing anything.

I store Music Library, Time Machine, and File Sharing on network drive. I really need to figure out the problem and fix this soon. Its much appreciated if you have same experience and already found solution, please share it with me.

I am glad to share with you that the problem is fixed without any changes. What I did is restart the Mac couple of times, and that's it. I think it even works faster than in Mavericks. I'm a happy man now.

Additional important thing is to update Java for OS X 2014-001. If you haven't done it, you can download it here.

Big thanks to Apple for the great gift



It's been a long waiting of Apple's event. It's a worthwhile waiting, Apple sports new products, iPhone 6, iPhone 6 Plus, and Apple Watch.  And a big surprise that Apple gives away U2 new album "Songs of Innocence" for free.

As a big fan of Apple and U2, I must say a very big thanks to Apple for the free gift. It's really, really a great gift from a great company I always admire, that keep providing great technology to the world.


For you who haven't download the album, you can access it from IOS device, iTunes, iTunes Radio, or Beats Music.

Setup Wifi on Raspberry Pi using Prolink Wireless-N Nano USB Adapter



I have had a lot of problems setting up this particular wifi dongle on Raspberry Pi. It is a Prolink Wireless-N Nano USB Adapter, WN2001. I like it because it is small compact, really fit to the Raspberry Pi.

When I googling I see that I am not alone. I followed all advises in many articles, including install compatible drivers, tried various setting options in /etc/network/interfaces file, etc. After many tempts I finally able to make it work.

I re-setup my rPi with latest Wheezy image from fresh. I found that the solution is very simple. I use the plain standard interfaces file coming from Wheeze, do not use wpa-roam (wpa_supplicant). In this example, I assign static IP for raspberry. Copy the below script, paste to the file and save.

sudo nano /etc/network/interfaces

auto lo

iface lo inet loopback
iface eth0 inet static
address 192.168.1.7
netmask 255.255.255.0
broadcast 192.168.1.255
gateway 192.168.1.1

auto wlan0
allow-hotplug wlan0
iface wlan0 inet static
address 192.168.1.8
netmask 255.255.255.0
broadcast 192.168.1.255
gateway 192.168.1.1

wpa-ssid SSID_NAME
wpa-passphrase WIFI_PASSWORD

Note that SSID_NAME and WIFI_PASSWORD is your Wifi name and password, write these in plain text without quotes. And of course, you have to adjust the IP address to your network credentials. I hope this articles can help you who use same device like mine.
