A car charger is similar to your MacBook charger, only that its end is modified to suit your car’s design. So, even if you are on-the-go, you can keep your laptop powered. Use a Universal Charger. A universal charger is the most convenient answer to your battery problems. Note: To use Night Shift on your Mac, you need to make sure your computer is compatible and running macOS Sierra 10.12.4. Night Shift doesn’t work with the connected televisions or projectors. Following are the Mac models and displays that support Night Shift. MacBook (Early 2015 or later) MacBook Air (Mid 2012 or later) Mac mini (Late 2012.

One of the most appreciable iOS features “Night Shift” is now available on Mac starting with macOS Sierra 10.12.4. Once enabled, it transfers the colors of the display to the warmer end of the color spectrum. As a result, your eyes won’t burn or strain.

The obvious advantage of using Night Shift on Mac is that you will have a better night’s sleep. Depending on your need, you can either set it to get activated automatically or set a custom schedule. Let’s find out how it works!

How to Enable and Use Night Shift in macOS Sierra on Mac

Note: To use Night Shift on your Mac, you need to make sure your computer is compatible and running macOS Sierra 10.12.4. Night Shift doesn’t work with the connected televisions or projectors.

Following are the Mac models and displays that support Night Shift.

• MacBook (Early 2015 or later)
• MacBook Air (Mid 2012 or later)
• Mac mini (Late 2012 or newer)
• MacBook Pro (Mid 2012 or newer)
• iMac (Late 2012 or newer)
• Mac Pro (Late 2013 or newer)
• Apple LED Cinema Display
• Apple Thunderbolt Display
• LG UltraFine 5K Display
• LG UltraFine 4K Display

Step #1. Click on Apple menu at the top-left corner of the screen.

Step #2. Next, you need to click on System Preferences.

Step #3. Click on Displays.

Step #4. Now, you have to click on Night Shift tab.

You can now create a custom Night Shift schedule or set it to get activated automatically from sunset to sunrise. To do so, simply click on the drop-down menu, select a schedule i.e. sunset to sunrise or set a custom schedule as per your need.

If you want to set a custom schedule, you have to select the time range during which you want to use Night Shift.

How to Adjust Night Shift Color Temperature on Mac

You can adjust the color temperature when the Night Shift is active. According to Apple, warmer settings might affect the appearance of some onscreen motion.

Step #1. Click on Apple menu → System Preferences.

Step #2. Click on Displays.

Step #3. Click on Night Shift tab.

Step #4. Now, you need to drag the slider left or right in order to make the color temperature more or less warm.

How to Disable Night Shift on Mac

If ever don’t want to keep Night Shift enabled, you can easily disable it.

Step #1. Click on Apple menu → System Preferences.

Step #2. Click on Displays.

Step #3. Click on Night Shift.

Step #4. Now, uncheck the box next to Manual.

If you have scheduled Night Shift, it will be activated at the scheduled time. If you want to completely disable it, just select Off in Drop-down menu next to Schedule.

Alternately, you can click on the Notification Center button located at the top-right corner of the screen. Then, scroll down and click the Night Shift switch to turn it On/Off position.

That’s it!

The Bottom Line

Night Shift is a very helpful feature for users. It had first arrived in iOS 9.3 for iPhone and iPad. If you are someone who uses Mac regularly at night, it would be of immense help to you. What’s your take on it?

If you leave your MacBook, MacBook Pro, or MacBook Air plugged in all the time—no matter the vintage—the battery suffers wear for being charged to full. Over time, the maximum charged capacity diminishes and you lose many minutes—even hours—of usable time. It is just a characteristic of the lithium-ion batteries in laptops and nearly all modern electronics.

Here is a quick list of the best practices for managing your MacBook’s battery.

• Routinely unplug your laptop, as frequently as daily, and let it drop its power down to the 30 to 40 percent range.
• Don’t fully discharge your battery regularly—that is, don’t let it run down to zero. As Battery University (not a degree-granting institution) notes, “If at all possible, avoid full discharges and charge the battery more often between uses.…There is no memory and the battery does not need periodic full discharge cycles to prolong life.”
• With modern Apple laptops, in macOS Catalina’s 10.5.5 release you can make sure that Battery Health Management is enabled in the Energy Saver preference pane’s Battery tab by clicking Battery Health.
• In macOS 11 Big Sir, recent Mac laptops will have more modern options enabled by default.

The lowdown on topping up batteries

Lithium-ion batteries are a far sight better than their nickel-based predecessors. Even the later nickel-metal hydride (NiMH) batteries required a regular full discharge—taking the battery down to no stored capacity—to keep them in good shape. Li-ion batteries are excellent at charging and discharging in varying amounts over time and losing relatively little charge when idle for long periods.

But the way in which they store energy requires careful charging past about 80 percent capacity. After that point, it’s easy for the batteries to overheat, which can damage them or, in the worst case, cause bulging or even fires. That’s why battery circuitry on all devices throttles charging speed from 80 to 100 percent.

If you ever wondered why your devices charge very fast and then very slowly, that’s why. And 100 percent isn’t really “100 percent.” It’s the maximum that a battery’s controlling circuitry or connected operating system believes it can safely hold when “full.”

Even with the most careful algorithms to get to 100 percent, lithium-ion batteries simply age faster when they’re topped up all the time. Battery University explains it succinctly:

Lithium-ion suffers from stress when exposed to heat, so does keeping a cell at a high charge voltage…Exposing the battery to high temperature and dwelling in a full state-of-charge for an extended time can be more stressful than cycling.

Apple recognized this as a problem with iPhones in particular, and built into iOS an awareness of a battery’s available capacity, which led it to throttle certain tasks when the battery couldn’t deliver enough juice without the iPhone shutting down. (See Settings > Battery.) Much has been written about Apple’s lack of disclosure, apology for the issue, and discounted battery-replacement program for older phones.

This minor crisis also led the company to add more detail about battery capacity and charge, and shape charging more intelligently. Apple no longer always ensures an iPhone and iPad charges to 100 percent when plugged in, but observes your charging patterns and adapts to charge only as necessary to give you the most stored juice you need at any given time.

That leads to greater battery life. My iPhone 11 Pro from last October shows 99 percent battery capacity, which is quite a bit higher than previous phones I’ve owned over that period of time. (The included one-year warranty on Apple’s battery-powered devices allow for a no-charge replacement if capacity drops below 80 percent in that first year. AppleCare+ extends that replacement for as long as you’re paying for the warranty.)

Apple brought a charging algorithm for its laptops that sport Thunderbolt 3 to macOS Catalina in the 10.15.5 update that isn’t quite the same, but it is designed to take the edge of a battery as it ages. In the Energy Saver preference pane’s Battery tab, click Battery Health. Battery Health Management should be checked; if not, you almost certainly want to enable it. (Mac laptops with Thunderbolt 3 currently include the MacBook Pro models since 2016 and MacBook Air models since 2018.)

With the preview of Big Sur, Apple promises the same sort of charging algorithm in iPhones and iPads for recent Mac laptops as well. It’s a painless and management-free way to get more life out of your laptop battery.
