It is common to think that a Mac computer does not need to be turned off. For this reason, while Windows computer users turn them off when they’re done using them, those with Macs tend to leave them on indefinitely.
Many Mac users engage in this behavior because they want to pick up where they left off, but also because experience has shown that Macs tend to tolerate this type of behavior, likely because Apple designed macOS and Macs to be very good in terms of performance. power consumption and performance. But is it really a good idea?
Each user has three options when they are done using the computer for the day: leave it on, put it to sleep, or turn it off. What is the best option?
Should I turn off my Mac or my MacBook?
Over time, processes and applications can clog up RAM and cause a slight drop in performance, especially on older Macs. Therefore, if a few days have passed since you turned off your Mac, you may feel that your Mac is slowing down or not performing optimally.
You can remedy this by closing and restarting apps, closing some of those many browser tabs you have open, or restarting your Mac.
macOS does a good job of managing memory usage, but sometimes the only way to give your device the clean slate it needs is to shut it down and restart it once more. This will clear your RAM and allow some processes that may have been stuck to restart.
It’s also true that some updates can’t be applied until your Mac restarts. Therefore, turning your Mac off and back on once in a while will ensure that everything is working as it should.
But how often should it be turned off?
Should I turn off my Mac at night?
Shutting down your Mac every night will probably do no more than save everything you were working on at the end of the day by le aving it turned on.

Is it better to put my Mac to sleep rather than shut it down?
When put to sleep, your Mac uses a reduced amount of power and can “wake up” much faster than the time it takes to turn on a Mac that has been turned off. In fact, new Macs with any variant of Apple’s M1 processor wake up almost instantly due to system configuration, making it an even more tempting option.
As a general rule, if you’ll only be away from your Mac for an hour or two, or even overnight, letting it sleep is probably the best approach. If it’s a longer period, it’s best to turn it off, for the reasons discussed in the next section.
In fact, you can consume more energy by turning your computer off and on again than by leaving it in sleep mode.
If you’re worried about the power consumption of an iMac or MacBook, don’t be; it’s really minimal when the screen is off and the Mac goes to sleep.
Laptops consume very little power when stopped and idle. 0.21W standby on a MacBook Air M1 will be 0.77kWh in a year if it’s idle for 10 hours every night instead of being turned off.
An iMac consumes a bit more power both off and idle, but 1.36W at idle is still low. 10 hours of rest every night translates into 5kWh of energy consumption in a year.
Of course, if you’re worried about your Mac’s resource consumption, turn it off when you go to bed.

To make sure Auto Shutdown works, you’ll need to shut everything down when you’re done using your Mac.
How long is too long to leave a Mac off?
If you plan to store your Mac for an extended period of time, Apple recommends that you do not leave the battery fully charged (100%) or fully discharged (0%).
If stored fully charged for a long time, the battery may lose some of its capacity, which may shorten its life. If stored fully discharged, the battery may fall into a deep discharge state, rendering it unable to hold a charge.
