I've been using Caffeine to keep the computer awake, but it also keeps the computer unlocked which is insecure. I need a method to keep my Mac awake (so that Dropbox can sync overnight) but also locked (so no one can read my email). It'd be great if this method also turned off the screen (to preserve power), but honestly that's not even 100%. I have some pretty big game files I need to download from steam, Would it be safe to do this overnight?I mean, Is there a chance it could catch fire or something?
Here's what you need to do if you want to use your Mac with the lid closed, including how to keep a MacBook awake with the lid closed or prevent it sleeping so you can continue with a download.
Check compatibility
If you're using one of these computers with OS X Mavericks or later,* you can install macOS Catalina. Your Mac also needs at least 4GB of memory and 12.5GB of available storage space, or up to 18.5GB of storage space when upgrading from OS X Yosemite or earlier.

* To upgrade from Lion or Mountain Lion, first upgrade to El Capitan, then upgrade to Catalina. To find your macOS version, Mac model, memory, and storage space, choose About This Mac from the Apple menu . If your Mac isn't compatible with macOS Catalina, the installer will let you know. View the complete list of compatible computers.
Make a backup
Before installing any upgrade, it’s a good idea to back up your Mac. Time Machine makes it simple, and other backup methods are also available. Learn how to back up your Mac.
Get connected
It takes time to download and install macOS, so make sure that you have a reliable Internet connection. If you're using a Mac notebook computer, plug it into AC power.
Download macOS Catalina
If you're using macOS Mojave, get macOS Catalina via Software Update: Choose Apple menu > System Preferences, then click Software Update.
Or use this link to open the macOS Catalina page on the App Store: Get macOS Catalina. Then click the Get button or iCloud download icon. https://stonespire.weebly.com/blog/sage-mac-os-x-download.
Begin installation
La chevaliere seth gueko download itunes. After downloading, the installer opens automatically.
Click Continue and follow the onscreen instructions. You might find it easiest to begin installation in the evening so that it can complete overnight, if needed. Intellij 2017 activation code free. Aloe blacc the aloe blacc ep rare.
If the installer asks for permission to install a helper tool, enter the administrator name and password that you use to log in to your Mac, then click Add Helper.
Allow installation to complete
Please allow installation to complete without putting your Mac to sleep or closing its lid. Your Mac might restart, show a progress bar, or show a blank screen several times as it installs both macOS and related updates to your Mac firmware.
Stay up to date
After installing macOS Catalina, you will be notified when updates to macOS Catalina are available. You can also use Software Update to check for updates: Choose Apple menu > System Preferences, then click Software Update.
Or get macOS Catalina automatically
If you're using OS X El Capitan v10.11.5 or later and your App Store preferences or Software Update preferences are set to download new updates when available, macOS Catalina will download conveniently in the background, making it even easier to upgrade. A notification will inform you when macOS Catalina is ready to be installed. Click Install to get started, or dismiss the notification to install later. When you're ready to install, just open the file named Install macOS Catalina from your Applications folder.
Learn more
- If the installer shows a list of apps that are not optimized for your Mac, learn about 32-bit app compatibility, then choose whether to proceed with the installation.
- For the strongest security and latest features, upgrade to macOS Catalina. If you have hardware or software that isn't compatible with Catalina, you might be able to install an earlier macOS, such as Mojave, High Sierra, Sierra, or El Capitan.
- You can also use macOS Recovery to reinstall macOS.

Is it safe to leave a laptop on overnight?
(14 posts)I just bought my first laptop and I'm really excited about it!
The salesman who sold me it told me that overheating is a problem with laptops, which do not have as efficient heat systems as desktops. He advised me not to leave it on for an extended period of time. I bought a cooling plate, and with the cooling plate on, the CPU temperature seems to stay consistently at around 48 degrees C. Is it really that bad to leave laptops on, or was this just a sales pitch to get me to buy the cooling plate? I'm glad I bought it either way, it does keep the thing nice and cool.

I have left my laptops on 24 hours a day since i got my first one 6 years ago and never had a problem with overheating.
The only problem i have had is with the battery, because i leave it plugged in all the time the battery never gets used, so now i have really poor battery life.
Someone did tell me to remove the battery if it is left plugged in, but it was too late for that, damage to battery already done.

You were the victim of a sales pitch but no real harm done. :) When it is on mains I would take the battery out to conserve it's useful life when you need it and the risk of an exploding or igniting battery is very real and you don't want that to happen when you are not there! My niece this very morning told me it's just happened to hers.

Don't leave it in AND the laptop switched on unattended for long periods..take it out and run on mains if you must leave it on.
Better safer than sorry!

My 2 laptops are on almost 24/7 but both are used on the mains regularly and with the batteries out. On this one, I don't think the battery has had more than 80hrs use in two years. The only downside here is if there is a power glitch whilst working on something so saving work (especially excel!) regularly is paramount.

quick point DON'T TRIP over lead and pull it out of the machine when your in windows,. ( to many to or else 1 time it may not boot or you could loose your unsaved WORK, the worse time is when its UPDATING ! ! ) .. like me but i was lucky it
booted pheww! but dont trust to luck, keep it tucked out of the way and the battery by the side of you to remind you its OUT lol
mark.
Another good point Mark, the power lead. Easily done. When doing updates it's always best to put the battery back in. I know this sounds like a pain but it keeps the battery in tiptop condition for when you do need it. Also just look at the price of an original battery replacement. Makes your eyes water!

ok, i have just removed the battery from my laptop, i had not even given the fire hazard a thought, i have heard of it happening but never really thought about it.
i keep the laptop on the arm of my fabric armchair, scary stuff when you spend a second and think about it.
the only problem i have now is the huge hole left where the battery was, any idea if you can get covers/battery blanks?
i have tried a search but came up with nothing, acer 5920g, might see if i can remove the cells and put the casing back. it only lasts for the matter of seconds anyway so the battery is of no use as it is.

DOGGOD, Your question is hijacking the OP's thread. You should ask in a New Topic. Thanks.
still releavent to the OP's thread though, if you want to leave a laptop top on overnight and remove the battery the op may be interested.
will start a new one tomorrow, just to keep you happy.
on the forum i run, it is encouraged to re use and keep everything together, makes searching easier, but i know you love new threads here for some other reason. :)

The reason being that confusion can rain down, when more than one person asks the same question in one thread. Different circumstances may apply.
And to answer the OP. There is no problem in running your laptop 24/7. Keep an eye on the temperatures tho. Especially if you live in a hot, or dusty environment. And it is best to raise it a little, cooling pad is not needed, but wire cake grill cooling tray works great. Very cheap. (or some chicken wire and 3 bits of wood)
There is NO problem if you leave your laptop running at night.
