Question: My printer/wireless/mouse/something else isn’t working. What should I do?
Like most electronic devices, the first port of call when something isn’t working correctly is to try the “simple fix first”. And with computers and devices the same can be said. So if something is playing up or not working as it should be, just give the computer a restart. (Click the Apple logo in the top left corner and choose “Restart…”) - you’ll be surprised at how many things this simple trick can correct.
In fact they made a whole segment about this in a British TV show called The IT Crowd - “have you tried turning it off and on again”
Question: How do I find out information about my computer?
When upgrading or changing computers, sometimes there is certain information required to help get some information about your current setup. Or if installing RAM (on older models), then the version of computer is required.
You can get this option by doing the following.
To find your Apple model, click on the Apple menu () in the top left, and choose “About this Mac”. On the new pop up window it will show which version of macOS you’re running (eg High Sierra 10.13.x, Mojave 10.14.x, Catalina 10.15.x etc) and which model it is (eg iMac (Late 2012), MacBook Pro 15-inch (Late 2012), iMac (Retina 5K, 27-inch, 2017 etc). Also on the window you’ll see how much RAM (Memory) you have (eg 16GB 1600MHz DDR3, 8GB 1333MHz, 32GB 2400MHz DDR4 etc).
If you click “System Report”, you’ll then get some further information under Hardware Overview. Normally the one required is the Model Identifier. This will be something like iMac12,1 or MacBookPro11,2 etc).
To find your hard drive capacity or space used, you can right click (or Command-Click) on “Macintosh HD” (or the hard drive) and choose from the drop down menu “Get Info”. You’ll then see “Capacity” (eg 1TB, 500GB etc) and “Used” (eg 323GB or 273GB).
This information can be very useful when trying to get details to someone about your computer.
Question: How do I take a “snapshot” of something on my screen?
You have two options to take a picture of your screen.
(1) If you want a picture of everything on your screen then you press the following key combination – Command+Shift+3
(2) If you want a picture of a specific area then you press the following key combination – Command+Shift+4. This presents a crosshair on the screen (+) You drag this “box” around the area you want to take the picture of.
Both this pictures will appear on your Desktop with the file name of “Screen Shot <date-time>”
Question: How do I Zap The PRAM? (And what is it and why would I do this?)
(The Parameter RAM (or PRAM) is a little chunk of memory that doesn’t get erased when the power goes off. Your Mac stores things like the current day, time, and which printer is chosen in that memory. Sometimes it becomes corrupt and can cause problems.)
To do this:-
1) Choose Restart from the Apple Menu ()
2) Straight away hold down the Command-Option-P-R Keys (Stretch those fingers!)
3) Keep the keys hold down until you hear the normal startup chime about 1-3 times. (On later machines, you won’t hear a chime).
4) Release the keys.
Question: How do I do an SMC reset?
Sometimes if certain things are playing up (battery, power issues, USB port issues etc) there can be a slight problem with what is called the System Management Controller (SMC), so doing a reset of this can help things run as they should. It differs for each model of computer, but it’s fairly easy to do.

Question: How do I set a Background Picture in Mac OS X?
If you have downloaded a picture or have something you want to use as your background it is very easy to change. Go to System Preferences and choose “Desktop & Screen Saver”. Where the current picture is, near the top left, drag and drop your new Desktop picture into the “well”
