Apple MacBook Pro A1990 Laptop Repair
installed newer version of Mac OS called macOS Mojave on an Apple MacBook Pro A1990 for a customer from Toronto Ontario CANADA.
The MacBook Pro “Core i7” 2.2 15-Inch (Mid-2018 True Tone Display, Touch Bar, Four Thunderbolt 3 Ports) is powered by a 14 nm, 8th Generation “Coffee Lake” 2.2 GHz Intel “Core i7” processor (8750H), with six independent processor “cores” on a single silicon chip, a 9 MB shared level 3 cache, 16 GB of onboard 2400 MHz LPDDR4 SDRAM and 256GB of onboard flash storage standard, and dual graphics processors — an AMD Radeon Pro 555X with 4 GB of dedicated GDDR5 memory and an integrated Intel UHD Graphics 630 graphics processor that shares memory with the system.
Externally, this notebook has an integrated 720p FaceTime HD webcam, a thin, backlit “third generation” butterfly mechanism keyboard with an integrated “Touch Bar” touch-sensitive control that adapts for different applications and provides Touch ID login support in lieu of traditional function keys, and a gigantic “Force Touch” trackpad.
Additionally, it has a high-resolution LED-backlit 15.4″ widescreen 2880×1800 (220 ppi, 500 nits) “Retina” display with True Tone technology, and a integrated battery that provides an Apple estimated 10 hours of runtime.
This notebook is offered in silver colored aluminum housing and weighs just a bit more than 4 pounds (1.83 kg).
Connectivity includes 802.11ac Wi-Fi, Bluetooth 5.0, four “Thunderbolt 3” ports (USB-C connector), and a 3.5 mm headphone jack.
Introducing the Apple T2 chip — second-generation custom Mac silicon designed by Apple to make MacBook Pro even more secure. Featured on the 13- and 15-inch models with Touch Bar, the Apple T2 chip includes a Secure Enclave coprocessor that provides the foundation for secure boot and encrypted storage capabilities. It also consolidates many discrete controllers, including the system management controller, audio controller, and SSD controller, into one. And the Apple T2 chip brings a familiar voice to MacBook Pro — Hey Siri is always ready to open apps, find documents, play music, or answer your questions.
MacBook Pro includes a solid-state drive that’s blazing fast, with sequential read speeds up to 3.2GB/s. This model features a 1TB SSD — enough space to take even your biggest files with you, like large photo libraries or video projects. So you can boot up, launch multiple apps, or import huge files in a flash. And with the Apple T2 chip, everything is automatically encrypted on the fly.
Easy on the eyes.
The Retina display in MacBook Pro is the best ever in a Mac notebook. It features bright LED backlighting and a high contrast ratio, delivering deep blacks and bright whites. It supports P3 wide color for even more vibrant colors than with sRGB and features True Tone Technology that adjusts the white balance to match the color temperature of the light around you — for a better viewing experience.
