For users with mobility or vision disabilities, keyboard shortcuts can be easier than using the touchscreen and are an essential alternative to using a mouse. This article itemizes the keyboard shortcuts for Excel for Mac. Many of the shortcuts that use the Ctrl key on a Windows keyboard also work with the Control key in Excel for Mac.
It lives inside your Applications folder and is present by default on the Dock (although of course, you don’t have to leave it there if you don’t want to). System Preferences is home to a collection of what are called “panes”, sometimes known as “prefpanes”. Each one lets you control various aspects of the way your Mac works. Some of them are very simple, others more complicated. The first one, Appearance, is simple enough.

When you open it, you’ll see various controls. There are drop-downs that let you pick one option from a list; radio buttons that let you pick one option from two or three; and tick boxes that let you switch things on and off. We’re not going to look at all of the preference panes in this post, although it’s certain that some individual panes will crop up in later posts in this series, because there are lots of useful tweaks and tricks you can do using System Preferences. What’s worth knowing for now is where to find System Preferences, and what sorts of things it does.
If you’re unsure which pane to use, type something in the search box at the top-right corner. System Preferences will instantly highlight the panes it thinks are most relevant.
Macs Fan Control provides something that only Apple possessed in the past: the ability to control how a Mac's cooling fans perform. This is actually a big deal, and something that shouldn't be taken lightly. Incorrect use of this app (or similar apps) could potentially cause damage to your Mac. Apple used advanced thermal modeling to come up with the cooling profiles used in a Mac's fan management system; Macs Fan Control can replace the Apple-supplied fan profile with one you create, and is geared more toward intermediate to advanced Mac users than beginners. That doesn't mean that if you're a beginner you shouldn't use it, only that you should use it carefully and wisely. • You've replaced a component in your Mac ( or graphics cards come to mind), and in the process, the old temperature sensors were damaged or are. You can use Macs Fan Control to set a fan speed limit to prevent a fan from revving up beyond what is needed.
• Your Mac is being used in a particularly noise-sensitive environment (such as a recording studio), and while you can normally use the default fan control, there are a few short periods of time where you need to silence your Mac as much as possible by preventing the fans from spinning up beyond a preset limit. That's how I primarily use Macs Fan Control: to monitor the internal temperature of the Mac I use, and to note the fan speed. Many times while using my Mac, I'll notice the fans picking up speed, increasing the RPM to cool down the Mac. For me, this seems to happen with specific websites, which I assume are using an unusual amount of, video, audio, or other 'special' content on their website in the belief that an ultra-dynamic interactive website is a better experience than their competitor's site. I usually just note the website URL and think twice about returning.
