macOS Mojave upgrade from macOS High Sierra Hackintosh

macOS Mojave is here for all the Mac users with supported MacBooks and Mac computers. Upgrading a Hackintosh to newer macOS Mojave is as usual not a piece of cake. I’ve been using macOS High Sierra from last year. You can watch the complete Installation here. macOS High Sierra doesn’t have compatibility for Intel UHD 630 Graphics so I was able to get my core i7 8700K working using fake ids and kexts for the graphics. In macOS Mojave, Intel UHD 630 can work without using fake IDs or Intel Injection.

macOS Mojave Upgrade

macOS Mojave can be downloaded from Appstore using your Apple ID.

Download it and open the App macOS Mojave.

Make sure to copy the “EFI Partition” to a flash drive as you may need it for booting the Installation. After the first reboot, sometimes the EFI folder from the SSD is removed. That’s why you need to boot via USB to use its EFI partition for booting up the system. Everything goes buttery smooth from there and macOS is upgraded to macOS Mojave in around 15-20 min. You’ll not lose any files during the upgrade process but it’s better to create a backup of your SSD.

Here is how you can create a bootable USB for macOS Mojave.

General Issues and Troubleshooting after Upgrade

  • Intel UHD 630 graphics acceleration wasn’t working due to injected fake Ids so I’d to change the config file. I was using Intel Graphics Fix Up in macOS High Sierra. macOS Mojave has built-in support for Intel UHD 630 graphics so you don’t need intel graphics fix up now. Delete intel graphics fixup from kext folder. and make sure you have the latest “lilu.kext” and “whatevergreen.kext” in the “kext/Other” folder.
  • You’ll be stuck at loading screen if you use wrong SM Bios. For Intel Core i7 8700K, select iMac 14,2 from the dropdown in SMBios tab.
    • Sky Lake: Select iMac 17,1 or iMac 14,2
    • Haswell: Select iMac 14,2
    • Ivy Bridge: Select iMac 14,2
  • Gigabyte / ASUS Motherboard users Only
    • Highlight Acpi on left column
    • Under fixes check FixShutdown
  • ASUS / ASRock / MSI / Motherboard users Only
    • Open config.plist with Clover Configurator
    • Highlight Boot on left column
    • Under Arguments press the drop down arrow next to darkwake
      1. Select darkwake = 1 if using an ASUS motherboard
      2. Select darkwake = 8 if using an ASROCK or MSI motherboard
    • Save config.plist
  • Magenta Tint on External Display/ Monitor
    • Open a terminal
    • Type Ruby and Drag “patch-edid.rb” next to it.
    • Press enter and this will create a new file in “Home” directory of your computer. Press Shift+Command+H to navigate to that directory.
    • Copy folder and paste in Installation SSD/System/Library/Displays/Contents/Resources/Overrides
    • Reboot your system. It will fix magenta tint.

7 beautiful Lakes of Pakistan

Lulusar Lake

Lulusar is a group of mountain peaks and a lake in the Kaghan Valley,  Khyber-Pakhtunkhwa province of Pakistan. It is one of the largest lakes in Pakistan.

The highest peak has a height of 11,200 ft (3,410 m) above sea level. Lulusar Lake also is a lake at 3,410 m (11,190 ft). The lake is 48 kilometers away from Naran on the Naran-Babusar road.

The lake is surrounded by snowcapped mountains, making it a natural tourist attraction.  In summers, when the surface reflects its surroundings sharply like a mirror, a large number of domestic and foreign visitors make it a popular destination.

You can take any car to the Lake due to the carpeted road. Lake is right on the Road going to Chilas from Naran.

Lalusar Lake is the main source of the Kunhar River, which flows through the entire Kaghan Valley through Jalkhand, Naran Valley, Kaghan, Jared, Paras, and Balakot until it joins the Jhelum River.

Lulusar Lake, Kaghan Valley

Saiful Muluk Lake

Saiful Muluk is a mountainous lake located at the northern end of the Kaghan Valley, near the town of Naran in the Saiful Muluk National Park. The lake is a source of the Kunhar River. At an elevation of 3,224 m (10,578 feet) above sea level, the lake is located above the tree line and is one of the highest lakes in Pakistan. Saiful Muluk is located in the Mansehra district of Khyber Pakhtunkhwa, about 9 kilometers (5.6 mi) north of Naran, in the northern part of Kaghan Valley. Malika Parbat, the highest peak in the valley is near the lake.

The lake is accessible from the nearby town of Naran during the summer season but access during winter is limited.

Saiful Muluk was formed by glacial moraines that blocked the water of the stream passing through the valley. The Kaghan Valley was formed in the greater Pleistocene Period dating back almost 300,000 years when the area was covered with ice. Rising temperatures and receding glaciers left a large depression where glaciers once stood. Melting water collected into the lake.

The Lake Saiful Muluk is named after a legendary prince. A fairy tale called Saif-ul-Muluk, written by the Sufi poet Mian Muhammad Bakhsh, talks of the lake. It tells the story of the prince of Persia named Prince Saiful Malook who fell in love with a fairy princess named Princess Badri-ul-Jamala at the lake.‎

Ratti Gali Lake

Ratti Gali Lake is an alpine glacial lake which is located in Neelum Valley, Kashmir, Pakistan at an altitude of 12,130 feet (3,700 m). The lake is fed by the surrounding glacier waters of the mountains.

As the lake is fed by glaciers, it does not have any designated inlets for springs and rivers and the route to the lake is easily accessible in the summer months. The nearest village settlement which serves as a base camp for the tourists who wish to visit the lake is Dorian. The flora and fauna of the area are well known throughout the world. Small animals such as otters are usually visible during the trek and large birds such as hawks. Flowering plants cover the valley during the summer season but during the snowed months there is almost no shrubbery to be seen. However, large trees continue to thrive.

Rainbow Lake

Rainbow Lake is in the Domel Region of Gilgit Baltistan. It’s in the restricted area so you’ve to take NOC from the army to visit it.

To go to Rainbow Lake, You’ve to travel to Chillam Choki from Astore. Then after crossing Burzil Pass at a height of 13808 ft you enter into Region which is somehow part of Kashmir. The first town on the way is Minimarg where you get the internet and all the basic facilities. In winter, snowfall here is average 10-20ft. From Minimarg you can go to Domel in Jeep and its 45min-1 hr Jeep Drive. You reach the lakes after crossing a series of check posts.

The lake was known as Yeldram Lake. Over the years, the spectacular appearance of two rainbows after every rainfall and the presence of rainbow trout in its water made it be known as “Rainbow Lake”.

Naltar Lakes

Naltar is a valley near Gilgit, Hunza, and  Nomal , Gilgit Baltistan in the Gilgit–Baltistan province of Pakistan. Naltar is 40 km (25 mi) from Gilgit and can be reached by jeeps. Naltar is a forested region known for its dramatic mountain scenery.

Skiing is a popular sport in the Mountains of Naltar. Ski resort of Naltar usually holds Ski competitions every year. There are two villages of Naltar valley; Naltar Bala, and Naltar Pine. Furthermore, Naltar Pine is at a distance of 34 kilometers (21 mi). And Naltar Bala at 40 kilometers (25 mi) from Gilgit. There is the main village known as Nomal between Naltar valley and Gilgit. A road from Nomal goes to ‘The Silk Route’ to China.

There are three lakes in Naltar Valley known as Naltar Lakes (Urdu: نلتر‎) or Bashkiri Lakes at an altitude ranging from 3050–3150 m. The first Bashkiri Lake is located at a distance of 12 kilometers (08 mi) from Upper Naltar (or the Naltar Bala).

The first lake is also called Satrangi Lake due to its unique blend of colors. Maybe the aquatic plantation is the cause for these colors.

Second Lake is also Called Blue Lake and it has a unique Azure color.

The road up to the lakes is a non-metallic dirt-road alongside a rivulet, flowing down the valley. The lakes are surrounded by dense pine forests, during winters it becomes almost impossible to reach the lake with any vehicle due to the heavy snow (10 to 15 feet high) on the road.

DJI Mavic Air review

Most wanted pocketable 4K drone in 2018

DJI Mavic Air packs 4K video recording, a three-axis gimbal, an upgraded obstacle avoidance system and onboard storage into a compact and foldable form factor that easily slips into a pocket or jacket or trousers.


  • Portability
  • 4K video at up to 100Mbps; 12MP HDR stills
  • Obstacle avoidance (APAS)
  • 8GB internal storage and MicroSD Card Slot


  • Could have better range
  • Need multiple batteries for a great flying experience
  • Initial Flight Setup takes time

DJI Mavic Air

The DJI Mavic Air is no doubt the hybrid child of the very successful Mavic Pro and the compact and user-friendly Spark. It’s a consumer drone that boasts some high-end features and shows DJI commitment to innovation. DJI Mavic air inherits the tech and foldable arms from the DJI Mavic Pro and the small form factor and portability of the Spark. It also has a remote controller, unlike the DJI Spark.
  • DJI Mavic Air at DJI for $799
The Mavic Air hovers perfectly above ground, offering high-end specs at a lower price point than the Mavic Pro. It has just about everything you could ask for, from 4K video and 32MP panoramic pictures to a 21-minute battery life. DJI Mavic Air is easy to fly, thanks to an improved object avoidance system and gesture controls, giving this drone more mainstream appeal.

Price and availability

  • Available now
  • $799 for the drone and accessories
  • $999 for the Fly More Combo
With a starting price of $799, the Mavic Air is cheaper than its bigger Pro sibling. You get the drone, a battery, the proprietary charger, redesigned remote controller, a small carrying case, four propeller guards and two full sets of propellers for this price. Due to limited flight time, you might want to reconsider investing in multiple batteries if you want to enjoy the full experience of flying. To get that out of the box with the Mavic Air, Fly More Combo priced at $999. It bundles the drone, three batteries, a remote controller, a travel bag, two pairs of propeller guards, six pairs of propellers, a battery-to-power-bank adapter and battery charging hub. Even though the starting price is a high investment for a gadget with a 21-minute battery life, the upgraded chassis with the tech housed within, makes the Mavic Air quite attractive, especially since it’s cheaper than its bigger brother. The Mavic Air is available via DJI’s online store and at major retailers.

Design and build

  • Compact and foldable form factor returns
  • Recessed gimbal adds protection, but the clip-on cover is awkward
  • Removable joysticks on the redesigned controller
  • USB-C port for data transfer only
The Mavic Air might resemble the Spark in terms of size, but that’s basically where the similarity ends. The new drone’s arms are foldable, like those of the Mavic Pro, taking portability to a whole new level. When folded up, the Mavic Air can quite easily slip into a large pocket – cargo pants or a big jacket. Weighing in at 430g, it’s heavier than the 300g Spark but lighter than the 743g Mavic Pro. The drone’s zip-up case reinforces how small it really is – it easily slips into a backpack or a camera bag with plenty of room to spare for the rest of the gear. Despite looking like a toy, the Mavic Air is solid and well-built. The recessed gimbal, with its clip-on camera cover, adds a layer of protection, making this a great travel companion. However, popping the cover back on after use can be a bit untidy, with no perfect way to clip it back on. You’ll just need to ensure the camera is facing straight ahead or you won’t get the cover aligned properly to slide into position. Taking a page out of Spark’s design, DJI has launched the Mavic Air in three colors: white, black and red. Although the colors are a playful touch, we found that the red and black versions were fingerprint magnets. The white version looks the best, but it can become more easily lost at a distance against a bright sky. The Mavic Air is the first DJI drone to introduce USB-C for content transfer. Sadly, the USB port can’t be used to charge the drone. For that, you’ll need to plug around the proprietary charger. Of course, it also comes with a microSD card slot, but this time there’s 8GB of onboard storage as well. So, if you forget to carry a card or manage to fill it up real quick, you can continue shooting with just a single tap. Another remarkable yet simple innovation that adds to the new drone’s portability is the redesigned remote controller. Out of the box, the joysticks for the controller are hidden away under the foldable smartphone clips, giving the new controller a flat surface that allows it to slide into the pocket at the back of the drone’s case. Just remove and screw them on, then unscrew and store away. The controller lacks the Mavic Pro remote’s built-in screen for flight telemetry, but squeeze your smartphone into the foldable clips and, you have access to a live video feed and every other piece of piloting information that you need.

Performance and control

  • Improved obstacle avoidance system
  • Gesture controls
  • Top speed of 68.4 km/h (40 mph)
  • Maximum transmission distance of 4 km (2.5 miles) with controller; 50m with mobile device
Setting up the Mavic Air isn’t hard if you’ve used a DJI drone before. If you haven’t, you’ll need to install the DJI Go 4 app on your phone (available for Android or iOS) and then follow the steps on screen to connect to the drone, either directly via Wi-Fi or by linking to the controller. Once set up, flying the drone is smooth as butter. And it’s fast, or at least feels that way because of its diminutive size. In Sport mode, this pocket rocket can reach a maximum speed of 68.4 km/h, or 40 mph. At such speeds, however, if the camera is facing sideways, you’ll capture the front propellers whirring, which may not necessarily be what you want in your video. That said, this isn’t a problem unless you’re pushing the drone to its top speed. Everyone, however, will experience the fact that the Air is loud compared to the much more expensive Mavic Pro Platinum with low-noise propellers. You’ll actually hear it before you see it when it’s just a small drone body in the distant sky. Novices don’t need to worry too much about the drone zipping around, either – the Mavic Air is harder to crash thanks to its seven-camera vision system and three-direction environmental sensing. DJI’s brand-new Advance Pilot Assistance System (APAS) doesn’t just stop the drone in its tracks when it comes against an obstacle – it’ll chart an alternate route and continue flying safely. However, for the APAS system to work effectively, the drone needs to fly around and survey the location for a bit, picking up information to process from its surroundings. That’s the only prep work involved, but it’s automatically done by the drone. During testing, we flew our drone towards stone columns in an abandoned quarry and the Mavic Air smoothly flew over some and around others without us letting up on the controls. That doesn’t mean the craft is completely crash-proof. There are no sensors on the top and sides, so there could still be a few close calls if you aren’t too careful. You’d expect that due to its small size and weight, the Mavic Air would have a hard time staying stable when hovering, but DJI promises it should be just fine in winds of up to 35 km/h (21.7 mph), and we were pleasantly surprised to find those claims seem to be accurate. Flying it by the seaside, when winds can pick up suddenly, the little craft remained remarkably stable in the air. The transmission range for the Mavic Air is limited to 4 km/2.5 miles using the controller. The Mavic Air relies solely on Wi-Fi instead of also using radio frequency (RF) to for its drone-to-controller connection. This has had some people at the time of the drone’s announcement worried that the drone connection would suffer. We didn’t experience that in our testing of three different drones on three continents. But, if you’re planning on pushing the Mavic Air to its distance limits, you may experience some dropouts in the video feed. Like the Pro, the Mavic Air features a three-axis gimbal, but it’s a redesigned one that makes this new drone much more stable. Although gimbal control while panning sideways is smooth, moving the camera up and down is still a tad jerky. To keep the footage as smooth as possible, it’s best to switch to Cinematic Mode on the app – designed to slow the drone down and reduce braking so video is smoother – but even this takes a lot of practice before you get a steady capture. It’s also able to track up to 16 subjects at the same time. When using ActiveTrack, our DJI Mavic Air review unit was able to track six subjects standing within the frame individually. However, when switching to QuickShot mode, you’ll need them all together, or choose one individual as the focal point. What made last year’s Spark a heck of a lot of fun to use was the addition of gesture controls. DJI has taken those smarts and improved on them and also given the Mavic Air better SmartCapture functionality. Using your hands, you can make the bite-sized quadcopter land and take off from the ground, fly towards and away from you, or get it to follow you around as you move. Making a peace sign takes a still shot while holding your thumbs and forefinger in a frame will begin and stop video capture. What’s a lot more fun than SmartCapture (and great for sharing on social media) are the additional QuickShot modes – called Asteroid and Boomerang. Like the older QuickShot options available on both the Pro and Spark, Asteroid and Boomerang have preset flights paths that capture short videos with a subject as the focus, and work with just a few taps on the app, no composition required. In the former, multiple shots are taken, then composed in-camera into a 10-second blip beginning with the subject and ending in a spherical bird’s-eye view of the locale. In Boomerang, the drone pans around the subject, then returns to its original point after a 360-degree circuit.

Image quality

  • 1/2.3-inch CMOS sensor and 4K video at 100Mbps
  • 12MP HDR stills; 32MP panoramas
  • ISO100 – 1600 for video and stills; ISO100 – 3200 for still in manual mode
  • Narrow ISO range doesn’t affect image quality except in low-light conditions
Of course, top flying tech and a stable gimbal amount to nothing if the built-in camera isn’t up to the mark, and thankfully the Mavic Air’s does not disappoint. The Air shares the same 1/2.3-inch CMOS sensor as the Mavic Pro, but has a narrower ISO range than its bigger brother, meaning it doesn’t do as well in low-light conditions. The Air’s capable of shooting 4K video at up to 30fps at a bit rate of 100Mbps. Drop the resolution and it can capture 2.5K at 60fps and Full HD at up to 120fps for slow motion. Those specs are great, but it’s the high bitrate that really makes the images pop with life, color and detail. In well-lit conditions, the Air’s videos are crystal clear, with near-perfect saturation, and there’s plenty of dynamic range to work with despite the small sensor size. In a gloomy setup we did lose some of that vibrancy, however, and our footage looked a tad washed out. Moreover, the gimbal helps keep everything we shot super stable, so even when the winds picked up and the drone got tossed around a bit, we couldn’t tell from the video. While you can shoot 12MP stills in HDR, the Mavic Air is also capable of taking panoramas. In addition to the horizontal, vertical and 180-degree panos, the Air can take a series of 25 shots of a scene, then stitch them together in-camera to produce a 32MP panoramic image.

Battery life

  • 21 minutes of battery life (fully recharges in 55 minutes)  
  • Closer to 18 minutes of true flight time per battery
  • 3 hours for the remote battery life (recharges in 3.5 hours)
  • We recommend Fly More bundle’s three batteries and charging hub
The Mavic Air battery life offers increased flight time over that of the Spark. It’s all thanks to the fact that DJI was able to squeeze a 2,375 mAh battery into what appears to be the same size battery as the Spark’s 1,480 mAh battery. The Mavic Air is rated for up to 21 minutes of flight time, though, realistically, you’ll squeeze 18 to 19 minutes of true flight time from a single battery. Like all of DJI’s drones, the Air lands automatically when battery levels are critically low (under 10%). I generally received a low-battery warning at around 15%, which gave us a couple of minutes to do what I was doing and then land it myself, or just wait for the automatic safety feature to kick in. All of this is still better than Spark’s 16 minutes of battery life. It’s also just six minutes shy of the more expensive DJI Mavic Pro flight time of 27 minutes, which is supported by a larger 3,830mAh battery and, for consumers, the top-tier Mavic Pro Platinum’s 30 minutes. If there’s one area in which the Mavic Air makes a small sacrifice, it’s here, but you’re going to have to spend a lot more for six for nine extra minutes in the air. This is why we recommend Fly More Combo for the Mavic Air with three batteries (and other accessories). It comes down to this: in many countries, especially in cities, it’s difficult to find a legal area and safe space in which you can fly. So hauling this drone somewhere – while ultraportable – for just 18 minutes of flight time is less than ideal. We monitored the charging time for the DJI Mavic Air battery and found it takes 55 minutes to charge each battery, which syncs up with DJI’s official specs for the drone.  With three batteries (and a nearby outlet to charge them), you could run the Mavic Air almost non-stop. At least until the controller gives out. That lasts three hours and takes 2.5 hours to charge.

Final verdict

The DJI Mavic Air gets a big thumbs-up from us. It’s the best drone for most people thanks to the fact that it fits top specs inside a pocketable drone form factor. We were able to slip it straight into our backpack without having it weighing us down. Getting 4K video at 30fps, better battery life, improved smarts and better obstacle avoidance for $799 (£769, AU$1,299) makes this drone a great value. Although the camera could have been better (DJI sadly hasn’t used the Pro’s 28mm f/2.2 lens on the Air), the footage it captures is still excellent.While the Air is capable to record at a resolution of 3,840 x 2,160 (4K UHD) at 30fps. The more expensive Mavic Pro is capable of Cinematic 4K (4,096 x 2,160) at 30fps. It also flies further and the Pro Platinum version is much quieter. For drone newbies, the Spark may seem like a great starting point, if you’re okay with 1080p images. Novice pilots might find it a bit hard to simultaneously pilot the drone and operate the gimbal smoothly. But it doesn’t take long to get used to it. And, by using the more automated QuickShots and tracking features, anyone is capable of pulling off an amazing shot.
