When your computer is running a bit slowly, how can you tell if getting more memory will help?

If you run out of free memory then your computer will be forced to use some of your hard disk as memory, which is VERY SLOW because hard drives are much slower to access than your computer’s RAM.  Here’s how to check that you have enough RAM to stop this happening on any Macintosh running OS X.  Continue reading ⟩

I recently decided to buy a hands-free Bluetooth speaker for my iPhone so that I could make calls while driving.  I read some reviews and decided to go for Motorola Roadster Pro.   All over the web reviewers are singing it’s praises. 9/10, 9.5/10, I even saw a 9.63/10!  Unfortunately, when it arrived, I discovered that the voice quality of the outgoing calls is woeful.

Most reviews are misleading because the reviewers only listen to the quality of the sound out of the driver’s speaker –  they don’t check the quality of the sound that the person at the other end of the phone call hears. So I ordered another 2 highly rated Bluetooth units and did a comparison.  They were almost as bad!  Here’s a comparison of the three.

Last week I had a hard disk crash.  If you’ve had a hard disk crash you may know it can take a day or two to get things up and running again, a day or two that I didn’t have.  I was flat our trying to get away on holidays before Christmas. Thankfully, I have a Promise Pegasus RAID array, and I can’t believe how great it was. I was up and running again in 30 seconds – I kid you not!  This article describes how it works for those who might be interested.

In this article I reviewed the Logitech wireless presenter. It is in my opinion the best remote control to use with Keynote. That particular Logitech remote has been replaced by the new Logitech R400 which doesn’t feel as robust, the main buttons are smaller, and it still has the 2 smaller buttons, one which completely exits out of your keynote presentation!  The last thing you want is to press the wrong button and be taken out of your keynote back to the desktop.

The smaller two buttons  can be easily disabled with a knife. This article describes how to disable the extra 2 buttons.  It really is a simple procedure and doesn’t even require any soldering!

When you are researching buying a mac there are a few things to consider, one of them is speed. There is a great site by primate labs which collates speed tests according to model and ranks them. This was useful for me when I was thinking of upgrading my Mac pro to a new Mac mini, only to find that my four-year-old  Mac pro was faster! Check out how fast the new mac-pro’s are  – insane – I wish I could justify buying one! Continue reading ⟩

When you plug in a second monitor to Macintosh computer, it may display an exact copy or ‘mirror image’ of what is on your first display.  This is called mirroring.  This is fine if you are doing a presentation and you want to see on your laptop screen exactly what is on the projector,  but it’s not very useful at home to have the same thing on both screens. If you’d like to see different things on each screen, so the second screen gives you more desktop space, you need to turn mirroring off. Here’s how.

This hint is not strictly Macintosh, but it’s so good I have to write it up. Did you know you can get what they call a Continuous inking system (CIS) for most big name inkjet printers? It continually feeds the ink into the printer so you don’t have to change the cartridges! You can see the big containers of ink in the photo above – they sit next to the printer.

There are two main ways to backup your Apple computer.

1. Use Time Machine to automatically backup. This is the Apple way – the easy way.


2. Manually backup your computer with some other software such as Super Duper or Carbon Copy Cloner.

If you are a beginner I recommend Time Machine. Look here.

Apple’s way (Time Machine) is a lot simpler. It’s automatic. It doesn’t rely on you remembering to do anything. The big disadvantage  is that the backup is not bootable.  So if your computer crashes you need to insert the original DVD and restore from the Time Machine backup. This process can take hours – not good if you are just heading out the door and need a file. But it will get your computer back to what it was like the hour before it crashed!

The second method takes a few steps longer to set up, but  your backup will be bootable. That means if  you plug your backup drive in, and then hold down Option-Command-Shift-Delete during startup,  you can boot instantly off your backup drive. In an emergency you can plug in your backup and be running from it under a minute. You can’t do this with Time Machine. The downside it it will only take you back to THE LAST TIME YOU BACKED UP.

I do both. I have time-machine running so my most recent work is always backed up, and I do a CCC backup monthly so I have an instant bootable backup ready to go for emergencies.

This article describes how to manually backing up using Super Duper. If you want to use Time Machine as well, here’s an article on how to backup using time-machine.
