When Apple introduced Yosemite, it changed the way it distributes operating systems for the Mac. Now, you can’t buy a copy of the Mac OS installer. That’s a problem if you have a limited broadband connection or metered broadband connection. You’ll need to create a portable offline installer in these situations.
The 'X' in Mac OS X and OS X is the Roman numeral for the number 10 and is pronounced as such. The X was a prominent part of the operating system's brand identity and marketing in its early years, but gradually receded in prominence since the release of Snow Leopard in 2009. UNIX 03 certification was achieved for the Intel version of Mac OS X. Get Skype, free messaging and video chat app. Conference calls for up to 25 people.

The first step is to go to the App Store and search for the current operating system. Currently, that’s El Capitan. If it’s already installed on your Mac, the App store will warn you the operating system is already on your system. If it isn’t already installed or you didn’t purchase it on your current Mac, under El Capitan it will say
If you’d like to create an installer for an earlier operating system you purchased, you can still do that from the App Store. Go to the
DiskMaker X is a free program that does the hard work of creating the USB installer. They do take donations, so if it’s helpful to you, you might throw some money in the tip jar.
After your open the program, it finds the operating system installers on your Mac. In this example, I’ll create an El Capitan installer. Next you’ll need an 8 GB or larger disk. This media can be a USB stick, but I use an SD card. Since most Macs that run Yosemite have an SD card slot, I think it’s easier.
DiskMaker confirms the disk you want to use for the installer. Then it warns you it needs to erase that disk. Confirm again you have the right disk and then click continue. After authenticating your Mac’s administrator name and password, a few minutes later you’ll have a complete installer.
If you’re more comfortable with terminal than using a third-party program, it is possible to create the installer. You’ll need a disk formatted
After you put in the password, the media creation process begins.
If you can download it again, why waste a flash drive or an SD card? Ideally, your Mac has a recovery partition you can boot off of to repair problems. Sometimes that partition isn’t there. An offline installer includes disk utility so you can solve problems.
The most common reason though is if your Mac’s hard drive fails. If you only have one Mac, you won’t have an easy way to reinstall the operating system. Creating the installer in advance solves the problem.This is true for Windows too:
Finally, if you want to reinstall your OS to troubleshoot problems, waiting for the installer takes a long time. When things don’t work, you probably wait for a download. If you’re on a slow connection, the download could take several hours.
Overall for the cost of one small USB flash drive or SD card, you can have the peace of mind that you can solve your Mac problems instantly.

The Apple A12 Bionic has about 6.9 billion transistors.
The first 32-inch Retina 6K display ever. Up to 1600 nits of brightness. An astonishing 1,000,000:1 contrast ratio and superwide viewing angle. Over a billion colors presented with exceptional accuracy. And dynamic range that transforms the professional workflow. Introducing Apple Pro Display XDR, the world’s best pro display.
The contrast your eyes see between brightness and darkness is very challenging to reproduce in a display, leading to the development of High Dynamic Range (HDR). With breakthrough backlighting technology, Pro Display XDR takes brightness, contrast, and color to a new level. Far beyond HDR, it’s Extreme Dynamic Range (XDR).
A brighter idea.
Typical desktop displays have sustained brightness around 350 nits. Some pro displays exceed this, but most can only sustain it for short periods of time. Pro Display XDR produces an industry-leading 1000 nits of full-screen sustained brightness and 1600 nits at its peak.1 It gives you the power to maintain extreme brightness without ever dimming. Along with efficient backlight control, this delivers outstanding contrast between the brightest brights and the blackest blacks. The result is an incredible 1,000,000:1 contrast ratio and stunningly real XDR imagery.
Show your truest colors.
Pro Display XDR always gives you the truest representation of your work. A P3 wide color gamut provides a color palette capable of creating the most vibrant imagery. With true 10-bit color, Pro Display XDR can produce more than a billion colors with extreme accuracy. State-of-the-art calibration and a sophisticated algorithm ensure that you get the highest-quality color possible.
True-to-life imagery requires having extremely bright areas of the screen right next to extremely dark areas. Without precise backlight control, this can cause an unintended glow called blooming. Pro Display XDR is able to dramatically reduce blooming using advanced LED technology, light shaping, and intelligent image processing.
Innovation in every layer.
Every aspect of the light imaging system in Pro Display XDR is crucial to the overall quality of what you see onscreen. Each element builds on top of the last to create a display with unbelievable brightness and contrast.
576 blue LEDs work together.
Typical LCDs are edge-lit by a strip of white LEDs. The 2D backlighting system in Pro Display XDR is unlike any other. It uses a superbright array of 576 blue LEDs that allows for unmatched light control compared with white LEDs. Twelve controllers rapidly modulate each LED so that areas of the screen can be incredibly bright while other areas are incredibly dark. All of this produces an extraordinary contrast that’s the foundation for XDR.
Light is mixed and shaped.
For even greater control of light, each LED is treated with a reflective layer, a highly customized lens, and a geometrically optimized reflector that are all unique to Pro Display XDR. Through a pioneering design, light is reflected, mixed, and shaped between two layers to minimize blooming and provide uniform lighting.
Color is transformed.
Converting blue light to white is a difficult process that requires extremely precise color conversion. It’s why most display makers use white LEDs. Pro Display XDR accomplishes this conversion with an expertly designed color transformation sheet made of hundreds of layers that control the light spectrum passing through them.
Brightness is taken to the edge.
Pro Display XDR extends exceptional image quality to the very edge. To ensure that LEDs along the sides of the display mix well with adjacent ones, a micro-lens array boosts light along the edges. This creates uniform color and brightness across the entire screen.
One chip makes it all possible.
With a massive amount of processing power, the timing controller (TCON) chip utilizes an algorithm specifically created to analyze and reproduce images. It controls LEDs at over 10 times the refresh rate of the LCD itself, reducing latency and blooming. It’s capable of multiple refresh rates for amazingly smooth playback. Managing both the LED array and LCD pixels, the TCON precisely directs light and color to bring your work to life with stunning accuracy.
Superwide viewing angle.
When multiple people review work together on a single screen, it’s critical that everyone sees the same thing. While most pro desktop displays claim a wide viewing angle, in reality, color and image quality become distorted when seen off-axis. With industry-leading polarizer technology, Pro Display XDR achieves a superwide viewing angle that maintains exceptional color and contrast.
Light scattered to further reduce glare.
And even less glare.
Every Pro Display XDR screen is engineered for extremely low reflectivity. And if you’re in an especially uncontrolled lighting environment, there’s an innovative matte option with nano-texture glass. Typical matte displays have a coating added to their surface that scatters light. However, these coatings lower contrast while producing unwanted haze and sparkle. The nano-texture on Pro Display XDR is actually etched into the glass at the nanometer level. The result is a screen with beautiful image quality that maintains contrast while scattering light to reduce glare to the barest minimum.
Professionals require a lot from their displays. But each person has different needs. Resolution, reference modes, reliable calibration. Pro Display XDR has everything you need in a modern workflow, bringing a new level of efficiency to every production. It wasn’t just made for the pro workflow. It redefines it.
Retina 6K. Expand your view.
Higher resolution means more than just a better-quality image. With a Retina 6K display, Pro Display XDR gives you nearly 40 percent more screen real estate than a 5K display. While most displays max out at around 150 pixels per inch (ppi), our Retina display has 218 ppi, providing astoundingly sharp and detailed imagery. It’s a massive creative canvas that easily fits 4K content, your tools, and much more all in one screen.
Many creatives. One vision.
Pro video workflows involve a range of professionals with unique setups. What’s always been missing is the ability to see the same image across an entire production. Pro Display XDR allows pros at every point in the process to experience exactly the same groundbreaking picture quality.
From the start of a shoot, Pro Display XDR reveals the content you’re capturing with incredible accuracy.
Image reproduction remains consistent across every point of your workflow, ensuring that everyone is always on the same page.
It’s easy to adjust Pro Display XDR to match the requirements of HDR, HD, SD video, digital cinema, and broader uses such as photography, web development, design, and print. Just select a mode, and the display reconfigures itself to match a specified color space, white point, gamma, and brightness. And coming soon, you’ll have the ability to create custom reference modes.
The lighting around you can affect the way you see onscreen colors. True Tone on Pro Display XDR uses a breakthrough dual ambient light sensor design — with a sensor on the front and another on the back — to better gauge your overall lighting environment. This facilitates more exact adjustments to the color and intensity of your display, so you can have accurate viewing in all lighting conditions.
Pro Display XDR is optimized to more than meet the standards of creative professionals. Every display goes through our state-of-the-art color calibration. Each of the display’s 576 LEDs is also individually calibrated and has its light profile stored. An algorithm then uses this information to determine the exact light intensity at which each LED should be modulated to produce the best possible image.
Pro Display XDR is stunning every way you look at it. Its screen stretches edge to edge with just a 9 mm border, so your work takes center stage. The aluminum enclosure is just an inch thick and features an innovative lattice pattern that reduces weight and increases airflow.
More air than metal.
The lattice pattern machined into the aluminum has many advantages. It more than doubles the surface area exposed to air, facilitating additional airflow and acting as a heat sink. This allows for fast and quiet cooling, enabling Pro Display XDR to sustain an extreme level of brightness indefinitely. Inlet and exhaust vents work through this pattern to draw in cool air and eject hot air away from the system, limiting the potential for hot air to be reingested.
Every aspect of Pro Display XDR was designed with pros in mind. Pro Stand is no exception. Height, tilt, rotation — it’s completely adjustable. It’s stable without taking up much space. And its ability to rotate to landscape or portrait makes it perfect for any type of work.
Pro Stand makes every adjustment of your display feel seamless. Precision tilting and 120 mm of height adjustment help Pro Display XDR adapt to any viewing condition. The angle of the display stays true even as you adjust the height. With Pro Stand, you get a display that feels weightless, moves effortlessly where you want it, and stays exactly where you leave it.
Every side is its good side.
Pro Stand gives you the ability to move between landscape and portrait whenever you want. All you have to do is unlock the slider and turn the display. Whether you’re a developer, a photographer, or a composer, you can see more of your work without endless scrolling.
Detach. Move. Attach.
Having the freedom to move between being on set and working in the studio can make a big difference. The magnetic connector on Pro Stand makes it easy to attach and detach from its polar-opposite magnet on the back of Pro Display XDR. These magnets guide the connection while latches automatically engage and securely lock the stand to the display. Detaching it is as simple as unlocking the slider.
Available VESA Mount Adapter.
Many pros have unique mounting setups for their displays. The VESA Mount Adapter attaches to the display in a matter of seconds for quick and easy mounting.
