- Free - Download any files faster - Integrate with browsers (using extension) - Download torrents - Download Youtube videos (in many formats or sizes) iGetter is a good alternative; it's free, supports browser integration, and can download a whole site.
It can download videos from Facebook, just clicking on the panel at the top right corner of a video without even playing. It also provides an option to download different video sizes.
It's free, can download torrents and Youtube videos (in many formats and sizes), and integrate with browsers to capture downloads. iGetter is a good alternative but is supported only by earlier Mac OSes at the moment. iGetter can download a whole website but not torrents and Youtube videos.
I'm using it to play movie files (MP4). It's easy to add and adjust the color and size of subtitles. I can also adjust the brightness and contrast of a video so that it's not too dark to see.
My Macbook Pro 13-inch Early 2011 is in the list of Bootcamp Support for Windows 7 and Windows 8, but not Windows 10. It means that my machine would be fine running Windows 7 and Windows 8, yet some hardware might not be recognized when running Windows 10. However, later Mac models work just fine with Windows 10 because Apple provides hardware drivers (Bootcamp Support) for them.
[Method 1] HEREis how I successfully installed Windows 7 via VirtualBox. And here is some solved issues happened during installation. It worked with Windows 10 too, just using a Windows 10 ISO file instead, but sound didn't work out of the box. There were several steps to do for solving the sound issue. However, built-in keyboard and USB mouse worked fine without insalling drivers from Bootcamp Support (but I wasn't able to adjust screen brightness, keyboard backlight, and sounds using function keys).
[Method 2] I was also able to install Windows 10 using a bootable USB stick (created by Bootcamp app) but built-in keyboard, trackpad, and USB mouse weren't working when starting Windows for the first time so I couldn't even install the drivers from Bootcamp Support. I had to press and hold down the power button to shutdown the machine and start it again; then Windows did some repair tasks and rebooted the machine, and the keyboard and USB mouse started to work so I was able to install the drivers from Bootcamp Support and then Windows updates. However, sound and external monitor weren't working. Sound issue could be fixed by the steps described in the section below, but external monitor couldn't, even after installing the monitor driver and firmware updates and manually updating the graphics card's driver).
Fixing WiFi, Camera, Bluetooth, and external monitor
I got WiFi, Camera, Bluetooth, and SD card reader working using Bootcamp Support version 5.1 (intended for Windows 7 and 8 only), but I had to manually install them one by one, by clicking on their corresponding setup files located in the Broadcom and Apple folders the Bootcamp Support file. I also manually installed other drivers that came along, thinking they might be useful though I didn't know what they were.
After installing Windows Updates and some drivers from Bootcamp Support, I was able to adjust screen brightnes (in Settings > System > Display) and use my external monitor connecting through Thunderbolt-to-VGA adapter.
Fixing Sound
At first, I followed everything from the video below (I backed it up here in case it gets deleted from the channel).
Here is the steps from the original post that the video referred to.
The sound still didn't work for me though it did for many others on Youtube. Under Sound, video, and game controllers section in the Device Manager settings, the sound driver got a yellow exclamation mark on it as shown here:
Then, I right clicked on it and select Update driver > Browse my computer for drivers. Then, in the Search for drivers in this location box, I browsed to DisplayAudio folder in the downloaded Bootcamp Support file and clicked OK. For my case, the location is C:\Users\Bros\Documents\bootcamp5.1.5769\$WinPEDriver$\IntelHDGraphics64\DisplayAudio.
The yellow exclamation mark was gone but I still couldn't hear any sounds.
After that, I installed this driver CirrusAudioCS4208x64.exe from the Bootcamp Support file but still no luck. For my case, the file location is C:\Users\Bros\Documents\bootcamp5.1.5769\BootCamp\Drivers\Cirrus.
It worked after installing another driver, CirrusAudioCS4206x64.exe, located in the same folder. And the sound drivers in the Device Manager settings updated their names as shown below.
I bought my monitor, Samsung SyncMaster SA300, over 10 years ago as a part of my desktop computer. I had been using Windows XP and 7 since then without any eye problems. About 5 years ago, I switched to Macbook Pro 13'' 2011 running Mac OS X Lion, and I connected it with that monitor. I still got no problems. When I upgraded OS X to Mavericks, my eyes hurt after staring at the laptop about half an hour, but they were fine staring at the external monitor.
Then, I installed Windows 8 on my Macbook Pro, and i got mild eye strain staring at the external monitor for about 15 minutes, but no issues with the Macbook Pro's screen. The display profiles of both screens are the same, sRGB IEC61966-2.1.
It wasn't comfortable staring at the screen all day, and I was afraid it might harm my eyes in the future so I tried other profiles installed on the computer but none of them worked. Then, i tried this one, Samsung SynMaster F2380, from this website, and at first, I felt the relaxation in my eyes, but after trying it for about an hour, it's hard to open my eyelids but no pain nor eye strain.
Finally, I found the solution. It's installing the monitor's driver. I checked the Device Management and the monitor's name was Generic PnP Monitor. After installing the driver from here, its name changed to SyncMaster S20A300B / S20A350B (Digital).
And I also modified the Device Profile of the external monitor as following:
The problem was gone, and I could stare at the screen all day with no problems.
Traditionally, internet is accessible to every home via the normal telephone lines connected. The data transmitted from the telecommunication company (also ISP) to a DSL modem inside each home is in form of analog (voice) signal. Then, the modem converts the analog signal to digital signal and sends it to a connected computer.
The digital signal is represented by the number zero (0) and one (1). But physically, it's a voltage pulse. For example, if the modem detects the voltage pulse from within the cable greater than zero, it interprets as 1; otherwise, it interprets as 0.
The analog signal is pictured as a wave signal. But physically, it's just a series of voltage pulses within a timeframe. The voltage generated within the cable continuously rises and drops again and again within a time interval so that the signal receiving device can conceptually interpret it as wave frequency.
It comes from the Greek word "Atomos". "A" means not and "tomos" means cut so atom means indivisible (unable to be divided). It's the basic building block of a matter. Atoms can join together to form a molecule.
Electric charge
It can be negative (electron) or positive (proton). While opposite charges attract each other, the same charges repel each other.
Particle
A particle is the small piece of anything (from vocabulary.com). For example, oxygen and hydrogen are particles. A molecule can also be referred to as a particle. An atom is made up of three (sub) particles: neutron, proton, and electron.
Molecule
It's a particle made up of two or more atoms that are chemically bonded together. The number of atoms within a molecule is a determined number, and it identifies the particle. For example, a water molecule consists of two atoms of hydrogen linked by covalent bond to the same atom of oxygen.
