======================================== Installing Windows and Linux together on a Mac. ======================================== 1. Introduction So, hello and welcome in my first guide. I will show you how to install Linux and Windows together on a Mac computer. Doing triple boot is also possible, if you would like to keep MacOS, but I lack knowledge to provide the detailed instructions. 2. Prerequisites *A Mac computer, of course 🙂 *Two pendrives, unless you have a second computer. *An external sound card, (Macs before 2014 don’t support sound in Windows when its installed in EFI mode) *An ethernet connection (only during the installation) *A legal Windows copy, it can be bound to your hardware. *It also helps, if you have a place to back up your data. 2. Let’s download and burn our operating systems! So, if you meet al the requirements, we can start preparing our USB drives with Linux and Windows. In this example, I will be using Antergos as the Linux distribution, from the operating systems I have tested, this one has the best Mac support. You can get it from https://antergos.com Windows is easily optainable from Microsoft, so I will skip this step. I will also skip steps for burning the Linux image, as it is different for each host operating system. For burning the Windows image, it is recommended to use diskpart, as some files needs to be removed. So, if you have the Windows image downloaded, enter diskpart Win R cmd diskpart list disk sel disk disknumber (where disknumber is the number shown in the previous command. Make sure it’s your pendrive, otherwise you will lose your data) clean convert gpt format quick fs=fat32 label=disklabel (where disklabel is the name you want to call your disk) exit exit (to exit diskpart and the main cmd) Then, mount the ISO image of Windows and copy all files from it to the USB stick, and remove bootmgr and bootmgr.efi files from it. Our Windows stick is now prepared, keep in mind, that even if it’s the latest version of Windows10 you won’t have speech unless you plug in the external soundcard. 3. Let’s install Linux! OK, so I assume you have your data backed up, as we will be converting the partition table from hybrid MBR to GPT. *Boot your PC from the Linux stick #1. Shut down your mac #2. Plug in the pendrive with Linux #3. Power on your mac #4. When you hear the ding sound, hold down left alt key for about 10 seconds #5. Press left arrow once and enter to boot the computer from external drive. #6. Wait about a minute to allow the system to load, then press alt f2, type orca and press enter. The speech might be quite quiet, press f12 to turn up the volume. As the antergos installation can be a bit tricky with the screenreader, I will try to explain it alittle. You will be asked if you want to install Antergos, select no, then press alt f2, type gnome-terminal and press enter. While in the terminal window, type cnchi and press enter. You will be placed in the installer’s window. The first box is used to select your language, you do it by pressing up and down arrows. When you are done, press ctrl tab and then enter on the button. The next step is a bit tricky, because here the hardware tests are performed. Wait about 30 seconds, press alt tab and go back to the window again. here the tab key might not work, if this is the case, use Orca’s object navigation to select the second unlabelled button. Then, the installation is straightworward, but we will have to partition our disc soon. If you have the GPT partition table, you can skip the below step. If you are running the mBR partition table, you will have to convert it to gpt by selecting “new partition table” button and selecting GPT. ***Warning*** This will remove all of your data from the hard disc! OK, I assume you have your table converted, now we can start partitioning. keep in mind that you will be installing Windows on the same HDD so leave some place for it. You have to create two partitions. The first one is where your data and Linux itself are kept. It should be mounted at the default place, just leave the mount point as it is. It should be ext4 filesystem. Ext4 should be selected by default, but you can check if it’s really ext4. The second partition must meet the following requirements. *The size should be 576 MB *The filesystem should be FAT32 *The mount point should be /boot/efi. OK, if the partitions are created correctly, select the second unlabelled button. I recommend you select the gnome desktop as your default, I will cover this in detail in the next article about Linux. After the system is installed, select the reboot option. Wait about 2 minutes for the system to reboot and you will be placed in the lightdm log in screen. Press enter and type your password to login. Then, press alt f2, type orca and enter. You should have speech. Next connect to your wi-fi network if you want. OK, so the Linux side of things is properly configured, now we can move on. 4. Installing the rEFInd boot manager. As you probably know, Mac’s hardware is quite differend from the computers you have probably seen. It means, the special steps need to be taken in order for the dual boot to work correctly. Thanks to Roderick Smith we have very good, flexible and blind accessible rEFInd boot manager. Using this tool, we can safely install Windows and Linux on a mac! *Getting rEFInd. rEFInd can be optained from the following link https://sourceforge.net/projects/refind/files/ We are interested in the Unix binary, don’t download the rpm or deb packages. *Installing rEFInd If you have downloaded the file, extract it and open the folder in your terminal. If you are in rEFInd’s main folder, execute the following command chmod +x ./refind-install This will make the ./refind-install script executable. Then execute the following ./refind-install The script will ask for the password, type it and press enter. Read the log carefully to make sure the installation went well. You can reboot to check if the rEFInd menu will pop up. If yes, press enter to boot to Linux again. 5. Installing Windows So, hopefully we have the boot manager installed and working. Now, we can install Windows. Boot in to Windows same as we did with linux, but remember, you have to plug in the external soundcard. Windows installation is easy, so I won’t cover it in detail, but I just want to point out some things. *Remember to not accidentally overwrite your linux installation *This is not Linux, you won’t have wi-fi access unless you install the bootcamp drivers. *After the first restart, the computer won’t load. Here’s how to workarround this problem. Shut down the computer with the power button, if it’s stuck on the white screen. Power it and enter the boot menu as we did twice already Press enter twice to boot the computer from the hard disc. Now the installation will go well. 6. Repairing rEFInd After the installation and basic configuration of Windows, it’s time to go back and play some more with Linux, but how? As some of you might already know, Microsoft has its own bootloader which overides rEFInd or any other boot loader we can have installed on our computers. We will have to reinstall rEFInd from the chroot environment. #1. Boot from the Linux stick as we did before #2. Mount your EFI partition. You can check which one it is by executing the lsblk command. You will recognise the EFI partition, because it will be 576 MB in size. mount /dev/sdax /mnt where x is the number of the efi partition. #3. Remove the rEFInd directory sudo nautilus /mnt Right arrow to EFI enter Right arrow to rEFInd Shift delete, confirm #4. Clear your NVRAM. In order to clear the NVRAM entries, do the following *power off your PC *Power it back on *After the ding sound, hold down windows, left alt, r and p keys till you hear the sound again. #5. Reinstall rEFInd. *Boot the Linux stick again *Mount your main Linux partition, use the lsblk command to find out which one it is. mount /dev/sdax /mnt *Chroot to your HDD system sudo arch-chroot /mnt *Move to the directory where you have the rEFInd installation files. cd /home/username/Downloads/foldername *Execute the ./refind-install script. #6. Reboot and enjoy! Now, your rEFInd is properly installed. When your PC will boot up, you will be presented with rEFInd’s main menu. The menu is non wrapping so you can go some times left and the first option will be Linux, the second option will be Windows, third and fourth are the operating systems again, fifth is booting from the USB (method above will also work) and the sixth option is the memory test. 7. Conclusion After properly following this article, your dual boot should work correctly. If you have any questions feel free to mail me at nuno at nvps dot pl. Replace at and dot with @ and ., respectively. I would like to say a very big “thank you” to one of my teachers. Without her. this article would never be created because I wouldn’t have my dual boot set up correctly. I would also like to thank you Roderick Smith for rEFInd. Without him, booting Linux and Windows together wouldn’t be possible at all! Also thank you to my friends who taught me Linux :). And last but not least, thank you, dear Reader for stopping by and reading this article!

Blind and Low Vision Participants Needed for Survey on Smartphone and Tablet Usage! Individuals who are blind or who have low vision are invited to participate in a new, international study by the University of Montreal and the Munich University of Applied Sciences that explores the use of mainstream smartphone and tablet computers among users with vision loss. The aim of this study is to better understand which mainstream devices (smartphone or tablet computers, installable apps and accessibility features) are being used by individuals with vision loss, and what factors impact the decision to use a specific device for a particular task. Participation involves the completion of a confidential, online survey that should take no more than 30-45 minutes of your time. The results from this survey will assist rehabilitation professionals and assistive technology instructors, by providing them with a better understanding of how to implement mainstream devices into their training. Participants must be aged 18 years or older, must have been using a smartphone or tablet for at least three months, and must self-identify as having a visual impairment (blind or low vision). You will have the option at the end of the survey to include your name in a draw for a $100 gift card to either the iTunes (Apple) or Google Play stores, and will also have the option to request a summary sheet of the results once the study is complete. This project has been approved by the ethics committee of the Centre de recherche interdisciplinaire en readaptation (CRIR). If you would like to take part, you can learn more about the study and how to sign up here: https://touchscreen.hostedincanadasurveys.ca/index.php/436191?lang=en&encode= We thank you for your participation and invite you to share with others in your networks!

Don’t you know this feeling, you have an app that you want to buy and your iTunes account just ran dry but you don’t want to waste 15 dollars on an app which costs just 1 dollar? For those who have a credit card this is no problem. but not everyone has a credit card, so, what to do? Apple just started rolling out the feature to pay with paypal and finally implements the same eas with paying as we know it from the google playstore since over three years. This will make buying apps, books, movies and so on for those who don’t have a credit card easier. All those last years, the only payment method was by credit card, if you got lucky, you could also pay with your phone bill, this feature came around in Germany about a year ago. If you want to enable your paypal account, on your iOS device, go to the settings, Itunes and Appstore, Click on your apple ID and open the payment settings and add your paypal account. For mac OS this feature hasn’t been officially announced for the appstore yet, but you already can set this up in your iTunes app and it will work in the appstore of Mac OS. If you can’t find the paypal option on your device. Go to. appleid.apple.com and try it from there. The feature is currently published in 12 cuntrys, including Mexico, United States, Canada, Singapore and Germany but will be available to more cuntrys in the coming days and weeks. For those who don’t have a credit card, especially outside the USA, this might be a good adition to the iTunes store.. If you have any feedback or questions, feel free to mail me under. moritz.grandjean@hotmail.com Kind regards Moritz Grandjean

The latest innovative technology for the blind and visually impaired, OrCam, is a device that can change everything for those with visual problems. Essentially, it’s a tiny high-tech camera that attaches to reading glasses. They are a pair of smart glasses for the visually impaired and for the blind that can revolutionize reading, and help blind and visually impaired, even those with reading disabilities, to re-gain their confidence and independence. All one has to do is point their finger towards anything that they want to “see”–be it text, a street sign, even the face of a loved one. And with that point of a finger, the device can “read” the text aloud in your ear within seconds. It’s truly cutting-edge technology. This device is life-changing, and this assistive technology for visually impaired people, as well as blind people, has the potential to dramatically change the lives of thousands.
