How to update your Mac

From large MacOS upgrades to minor but important security or usability updates, it’s important to keep MacOS current. If you're not quite sure how to do that, don't fret. It's quick and easy. Even if you have automatic updates turned on for your Mac, the manual method is just a few steps long.

If you find yourself in any of these situations, our guide will show you exactly what needs to be done to put those Mac updates into effect. Take a look.

Prepare for an update

Updates will reboot your Mac, so prepare for a full reboot process. Finish any current tasks you’re working on, close out of browsers and apps, and make sure any documents are saved and closed before you work on the update.

You may also want to back up your data with Time Machine or something similar. Mac updates don’t usually bring bugs, but it can happen, and if you have very important, time-sensitive data on your computer, make sure you also have a way to access it if something goes wrong.

Look for notifications

If you have the System Preferences icon in your Dock, you may see an indicator that an update is available. When you select that icon, you'll head directly to System preferences and see that same indicator on the Software update item.

Open the Software Update tool

If you don't have the icon in your Dock, you can open System preferences from the menu bar.

Step 1: Select the Apple icon in the upper-left corner of the screen and choose System preferences from there.

Step 2: Once in, look for the option that says Software update. Again, you may see an indicator that an update is available. Even if it doesn’t appear, select Software update to head in and make sure.

Step 3: Alternatively, select the Apple icon in the menu bar and pick About this Mac. Then, select the Software update button.

Install the available updates

Once in Software update, if there are any updates that haven’t been applied, you will see a notification that says "an update is available for your Mac" or similar.

Step 1: Select the Update now button to get started.

Your Mac will then close out of any apps that you may have left open, reboot, and apply the updates.

Step 2: It’s also a good idea to select Automatically keep my Mac up to date in this window.

As we mentioned, this doesn’t always work well, especially if you rarely log out of your Mac, but it can often help apply updates you may not have noticed.

Step 3: You can also select Advanced to mark other automatic update options, like app updates from the App Store.

Aging out of updates

There’s an important caveat to Mac updates: they’re targeted at the latest versions of Mac computers and operating systems. That means they can include software changes that older Macs just weren’t made for. Rather than introduce bugs or create other problems, Apple chooses to cut off updates if your Mac is a certain age or older.

For example, the Monterey upgrade was limited to Macs only several years old. The same is true for smaller updates as well. That's important to remember if you're looking at refurbished Macs or wondering if it's time to upgrade a current Mac.

How to convert M4A files to MP3 on Mac, Windows, and web

Wouldn’t it be nice to live in a world where there’s only one file format for every byte of audio-video content? Crashing back to reality though, we’re stuck with numerous codecs, and one of these many formats is Apple’s MPEG-4 Audio (herein referred to as M4A). Podcasts, audiobooks, and songs are some of the most common types of M4A files.

How hot is too hot for your CPU?

Your CPU can probably run hotter than you think. In the past, 70 degrees might have set off some warning bells in your mind and within the confines of your PC. But modern processors are designed to run much closer to their thermal maximums when working on demanding tasks, and they can quite comfortably sit there for extended periods of time without it causing any problems.

That's not to say you want to redline your CPU all day every day, and there are definitely some advantages to running your CPU cooler than it can technically reach. But to do that, you need to know how hot your CPU can run, and ultimately, how hot is too hot for your CPU.
How hot can your CPU run?
While we can't provide an exhaustive list of every processor and their maximum temperatures, the good news is, we don't have to. Both AMD and Intel publish maximum safe temperatures for their processors on their respective websites, so we can look at a few examples, and if your CPU isn't covered, you can easily look it up yourself.

When it comes to cross-platform files, two of the most widely used image formats you’ll see are PDFs and JPGs. The Portable Document Format (PDF) was launched by Adobe back in 1992, while the Joint Photographic Experts Group (JPG) was unveiled the same year, and was developed by its titular organization, in collaboration with IBM, Mitsubishi, AT&T, and Canon.
