April 22 is Earth Day! ? Fun fact: each year Apple stores color the Apple logo's leaf green in celebration. Earth Day is about awareness of our environmental impact, and as the saying goes, it comes down to you. Today is a great day to understand how to better look after the environment-and, as a side effect of increased energy efficiency, you may even cut costs along the way.


By tweaking your Mac's settings, and maybe fine-tuning some of your hardware, you can run a more energy-efficient system and help for Earth Day .


Review your time saving settings


First, have a look in Apple menu System Preferences- > Energy Saver. Here you are able to choose settings associated with putting your display, hard drives, or your Mac to sleep.



Note that placing a spinning hard disk to rest when it's not in use certainly helps preserve energy, but can also cause annoying delays when you ask your Mac to carry out a task and contains to hold back for the drive to awaken . Addititionally there is a disagreement to make for motor deterioration of drives which are constantly sleeping and waking up again.


How fast your display is going to sleep entirely depends upon the way you use your Mac. You have to find the sweet spot between saving energy and avoiding being annoyed at needing to wait for your screen to awaken.


Also have a look at System Preferences > Desktop & Screensaver > Screensaver. Some screensaver options require a lot more processing power than the others, so if you have a tendency to walk away from your Mac often or discover the screensaver active for hours when you're not there to determine it anyway, just select the \”Message\” screensaver in which the entire screen goes black and a message of your liking bounces around. Better yet, if you're not around to see the screensaver, just set the display to go to sleep instead .


If you choose to make use of a screensaver, be aware that some third-party screensavers that could look cool, such as the Matrix running code or the [email protected] screensaver, may also use a large amount of juice. Obviously, screensavers do still serve an objective ; for instance, you can use a hot corner to activate a password-protected screensaver to lock down your Mac in an instant. For additional on that, take a look here.


Implement energy-saving schedules


In the sooner mentioned System Preferences > Energy Saver settings you can observe a control button saying Schedule. Using the schedule settings, you can power up, turn off, or sleep your Mac at set times. If you do not use your Mac after dinner, you are able to place it to shut down at 8pm and begin up again before you get for your desk the next day at 8am, for example. Schedules could be looking for weekdays, weekends, every day or individual days.


You may also want to put your backups on the schedule. Time Machine automatically runs every hour the whole day, but this also requires your external drive, Time Capsule, or server to spin up every time to receive the backup data. Do you want backups running while you are out of the office, or sleeping? Perhaps not.


A very nifty utility I have been using for a long time is TimeMachineEditor, and that i use it for every Mac which has Time Machine active. I even carry it out on my small clients' Macs. Many people do not have important files that change every hour but still want a regular snapshot in case. They can set the backup schedule to once every 6 hours, or in a set time throughout the day. For a lot of clients, especially those where you can find many people within an office, I stagger backup schedules for different departments or users so that the servers aren't hammered when every Mac in the office starts backing up at roughly the same time frame. TimeMachineEditor is an extremely useful app for this.


Intego's own Personal Backup also has scheduling features where synchronizations, backups, or clones can all be set to operate at specific intervals, and contains lots of other great features making it a powerful alternative to Time Machine.


Shut things down


Whether you turn off your Mac manually as needed or have it on the schedule, see if you can connect your Mac, displays, speakers, printer, powered hubs, along with other peripherals one power strip. Having the ability to shut everything removed from a single power strip keep can save some watts.


If you'd rather keep the Mac in sleep rather than turn off, you are able to at least put anything else on said power strip to seal off only your peripherals, and also to stop their trickle power consumption.


Note: A few of the tips below involve the outlet of, or even partial disassembly of, your Mac. If you're not comfortable with doing that, look for a friend or shop that is capable and also have them get it done instead. In some cases, self-repair may void your warranty, so consider taking your Mac to an Apple Store or an Apple-authorized repair center. Should you choose decide to open your personal Mac or get another person to get it done for you personally, you do so at your personal risk, obviously.


Replace spinning HDDs with SSDs


Spinning hard disk drives run hotter and wish more capacity to operate. If you're able to, swap out your spinner for a solid state drive , at least for the boot volume. This is easy to do if you have a 2006 -2012 Mac Pro, pre-Retina MacBook Pro, or 2006 -2010 MacBook, and requires a little bit more work on iMacs and Mac minis but it is well worth the effort. Not only will your Mac run cooler and much more efficiently, but it will also get a substantial speed bump!


If you need to do use your internal hard disk for a tremendous amount of data storage and can't afford a high-capacity SSD, consider replacing your spinning drives with more energy-efficient models. For example, while WD VelociRaptor or Black drives may be nice fast, do you really need the quickest spinners for data you are not accessing constantly? The answer is probably no. Instead, you might consider WD Green drives, which have a variable rotational speed, run cooler and employ less energy.


We're making good progress! But there are a few additional steps you can take to not only save on energy consumption, but also to extend the life of your Mac as well.  We'll collectively call these step number five: making your Mac run cooler.


Make your Mac run cooler


A Mac that runs hotter uses more energy. Hard disk drives running hotter have a lower lifespan. Heat causes fans to spin faster for cooling the Mac and it is components down, and faster fans means increased energy consumption . And we're not even getting in towards the enhanced effects of electromigration as heat increases! In short, a cooler running Mac is really a happier Mac, and better for that environment.


So how do you go about using a cooler running Mac? Glad you asked!


Clean out the dust


One of the greatest things you can do for the Mac is keep out the dust. Unfortunately that is easier said than done. If your Mac has one or more fans, it'll suck dust particles into the case that will accumulate with time. Even the Mac mini, which technically has no air intake, will suck in dust with the various ports and gaps towards the bottom cover. When dust accumulates, it hinders airflow and also the Mac will run hotter as a result.


Apple generally doesn't make it easy for customers to open their own Macs, with a notable exception being the Mac Pro. Proprietary screw designs are just one way Apple attempts to prevent you from accessing the internals of the Mac that you taken care of. Luckily, the best screwdrivers can easily be from places such as iFixit, and using exactly the same company's repair guides, you may be looking at your Mac's innards within minutes.


Follow iFixit's Mac take-apart guide for your model, and track of any screws and parts you are taking out. Once you are in, cleaning out the dust can be as simple as some well placed blasts of compressed air and some gentle cleaning from the fans with a soft brush. When you place it all together again, just stick to the same guide but in reverse order.


Cleaning the dust out of your Mac is not a one-time event. If you use your Mac in a particularly dusty environment, your Mac will benefit from regular cleanings. Don't forget there are companies and friends that can probably do that meet your needs.


Give it some fresh paste


Your Mac's main processor and graphics processor are usually included in a heat sink that pulls heat from the chips. Underneath that heat sink is thermal paste. Its sole purpose would be to bridge the space between your minuscule as well as microscopic scratches, gaps, and dents within the copper of the heat sink and also the die of the chip. When they may look smooth and shiny, they're not even close to perfectly smooth. Thermal paste fills in those microscopic gaps and provides heat in the chip an immediate road to heat sink.


When a subpar thermal paste is used, or maybe the paste doesn't cover all the chip area, or once the paste gets dry over time, the chips cannot transfer their heat towards the heat sink as effectively. When this happens the chips run hotter, the Mac uses more energy, and you may even experience reduced performance because of thermal throttling.



I would argue that the stock thermal paste Apple uses and exactly how it is applied are substandard given the Mac's cost, so re-applying the thermal paste is something I recommend to each Mac user regardless of the Mac's age. You cannot fail with Arctic Silver 5, but when you want the very best, you might as well spend some more dollars and choose Thermal Grizzly Kryonaut. A thin layer that covers the whole chip die is you'll need. Your chips will run cooler and your Mac will use less energy consequently.


Upgrade your external display


Here's an added bonus tip permanently measure. Remember those CRT monitors we mentioned earlier? If you are somebody that still uses one, it's probably time for you to let go. Regardless of how much you may still like CRT screens, replacing them with modern LCDs can help tremendously in order to save energy-and like a side benefit, you'll also gain a lot more desk space.


What else are you able to do?


I hope you've enjoyed getting to know your Mac and its energy efficiency capabilities just a little better. Let us know in the comments below that which you have done to make your Mac use less power, and have a happy Earth Day!
