When did your Mac last start up? Mine’s only been running continuously now for nearly ten days, but unless something forces me to, I don’t intend restarting it for another couple of weeks, and only shut it down completely a couple of times a year. You can also use the Sleep dropdown to schedule a Sleep, Restart, or Shut Down time if desired. Check the box next to Start up or wake. To be able to see usage information for every other device signed in to iCloud with your Apple ID, select Share across devices on each Mac.Click the Schedule button at the bottom of the pane. Click Options in the lower-left corner. Follow these steps in macOS Catalina or later: Choose Apple menu > System Preferences, then click Screen Time.This iMac Pro no longer has internal storage which spins platters, so it’s time to reassess what I do.Your Mac must be awake at the time you schedule it to shut down plus 10 minutes. I’ve been leaving my desktop Mac running constantly for many years now, and started doing so largely to reduce the risk of hard drive failure. And it’s not a bad idea to tweak your Energy Saver settings either, to configure sleep mode how you want it.Traditional arguments about this have been based on the last generation of computers, with internal hard drives. But temporarily turning off your Mac’s sleep mode is fine. It serves an important purpose, protecting your Mac and reducing unnecessary energy waste.
A screen that can display time and calendar events even while sleeping. IPhone 13, iPhone 13 Mini camera test: see how Apple’s new phone takes pictures. If your Mac is set to Sleep after less than 15 minutes of inactivity, it may Sleep before it can Shut Down.No gap design. Even if you’re using a MacBook Pro as your desktop system much of the time, you’re very unlikely to be interested in running it continuously.Download the latest version of Sleep Expert for Mac - Next generation sleep management app chosen by thousands of Mac users. Laptops are engineered for intermittent use, with periods of sleep or shutdown in between. Also suitable for chargers for Mac and non-Apple. In-screen fingerprint sensor for unlocking mobile phones. Location and your presence. If your Mac is unused from Friday evening to Monday morning, it’s likely to make sense to at least shut it down for that period each week. Although my iMac doesn’t contain them, it backs up to an external RAID which contains four conventional hard drives. Whether any part of your system still uses rotating disks. Even when sleeping, a desktop system uses electricity of course. Energy consumption and cost. I aim to replace my desktop when its AppleCare runs out, but many users will want a longer life. How often you replace it. If your Mac provides services to other Macs or devices, it needs to be running when those services may be required. If your Mac is going to be unattended for long periods, you need confidence in its physical (local) and Internet security. Automatic shutdown is essential, and needs to be tested too. Desktop Macs should always be protected by a UPS, but when they’re unattended for long periods you may want one with a higher specification to cope with mains outages when you’re not there. Most electronic engineering advice, though, continues to recommend that systems are left running in stable conditions as much as possible to ensure their maximum working life.Pattern of use is very important here. It has been claimed that repeatedly cycling the temperature of some components soldered without the use of lead – which has been banned throughout the EU for more than a decade – increases the risk of joint failure.However, since lead-free solder and its use with surface-mount components have undergone considerable improvement over that period, it’s hard to know how true or significant this might be. One factor which has been implicated in this is the use of lead-free solder. That should be a key consideration if any part of your system relies on conventional hard disks.One way around this is to use networked storage for backups you can leave that storage running constantly, but still shut your computer system(s) down when you wish.It’s generally accepted that electronics which warm up in use, as computers do, tends to run with fewer problems when they are left running at normal working temperatures for long periods. Leaving a disk running at constant speed at all times generally results in longer life before mechanical failure. Evidence shows that repeatedly spinning up and spinning down rotating hard disks reduces their working life, on average. Wacom cth 680 driver for macSo if I shut them down for 50 hours each week, I should save around 5 kW each week, or 250 kW per year, which costs me roughly £45 per year. This is relatively simple to estimate: in my case I’ve got an iMac Pro and my RAID, which together will use around 100-120 W when idle. Out of the 168 hours that it’s running each week, it could only sensibly be shut down for less than 50 hours, which is under 30%.Following on from that is the question of how much energy you’d save by shutting your Mac down. Although I do go out daily, at least, my desktop system is essentially in use seven days a week between about 0700 or earlier and 2330. However, the display should be set to sleep, same with the hard drive if it’s still using platters and must have a password. It’s best to leave it ON 24/7 if you’re on a modern OS like macOS or Windows 10 and your computer is quite modern. For the record, though, my never-sleeping iMac Pro does put its display to sleep, if only to stop the cat from sitting up watching its ‘screensaver’ at night.At the end of the day, it’s a personal decision on the balance of these different factors, and what you feel most comfortable doing.Hi. It’s pretty impressive.LCD screens, in general, do not burn-in, but can suffer from “image retention”, which is similar, but will go away in time if the image changes to something different. Make it an always ON computer, 24/7.Screen burn-in is definitely real, and may even be true today, for some displays.I’ve seen plenty of old Macs with CRT displays that have the AfterDark fish-tank background so burned-in that it is visible even when the computer is turned off!I’ve also seen used CRT displays from airport terminals sold at flea markets, where you can see the column-headings for arrivals and departures even when powered-off. It’s like sweating heavily from jogging for kilometers outside, then going into an air-conditioned room, then back again under the sun- you will most likely have pneumonia or catch another illness.As long as it’s set to sleep, the display especially, the wattage used during sleep not that much different from a shutdown. Sleep Time Driver Circuit ThatThe high voltage driver circuit that powers the CCFL can also fail over time.LED backlighting doesn’t burn out, but (like all LEDs), it does get dimmer over time. The tube can sometimes be replaced, but that procedure can be difficult and expensive, depending on your display. So a region of the screen that is brighter than the rest for an extended period of time will start to appear dimmer than the rest.Additionally, LCD displays can suffer problems if the back-light is turned on for extended periods of time.LCD panels that use CCFL tubes for backlighting can go dark when the tube burns out. More accurately, pixels age faster when they are brighter and older pixels don’t get as bright. I wouldn’t bother with a fancy animated screen saver – that is strictly eye candy, but putting the screen to sleep (powering-off the CRT or the LCD backlight) should definitely increase the life of that display.
