In 2015 I wrote this post about installing an SSD drive. Back then SSD drives were expensive and the whole process I described was a bit complicated. Now SSD drives have dropped dramatically in price and you can just replace your existing drive with an SSD one. I can’t think of any reason why you should not be using one. All MacBooks now come standard with an SSD drive. If you have an older one that you’d like to upgrade you should be able to take your Macintosh computer to a local dealer and have them install an SSD drive. Otherwise you can have a go at installing one yourself.
Lots of people have commented on the possible increase in EMF exposure from Apple AirPods, but how bad are they? I’ve done some measurements with a field strength meter. Here is a graph to give you an idea.
When you use the new Apple Airpods on a mobile phone call a you are getting approximately 10 times the EMF than if you were just holding the iPhone up to your ear and talking. We already see these levels on wifi devices. The difference is that the Apple AirPods are in your ear, not on the table, and they remain there for long periods of time. They are constantly transmitting at this level – they never turn off.
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 〉
Seagate make two external USB drives. The Seagate Backup Plus and the Seagate Expansion. They are both USB 3 compatible. They both come with a three-year warranty in Australia, although in the USA the expansion only has a 1 year warranty. The Backup Plus model costs $20 more. A lot of reviewers say that the backup plus is more reliable (e.g. this one). But is there any difference? I pulled them apart to see!
The Apple 24 inch LED Cinema display and the Apple thunderbolt display have been a source of frustration for many people. They flickers, go black, the screens gets garbage on them, the fans turn on and off. After reading lots of forums and trying various things I have practically completely eliminated all the flickering on my 24 inch LED Cinema display, here is how. Continue reading 〉
One of the features I use regularly in the display settings of OS X is the adjustment of the gamma setting of my monitor. This is useful because it can lighten up dark movies when you are watching them on your Mac. The gamma setting is only available in the “expert” mode of display settings which has disappeared in El Capitan. Thankfully expert mode is still there, it’s just hidden. To get into expert mode on El Capitan hold down the option key when you select ‘Calibrate…’ in display settings. Continue reading 〉
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.
I just upgraded the boot drive on my Mac Mini to an SSD drive. WOW! It is by far the biggest speed enhancement I’ve experienced on any computer! The speed increase is incredible – almost hard to believe. Boot time went from 60 seconds to under 30 seconds, and applications launch instantly – no bouncing dock icon.
This is not for the beginner – it’s quite technical – but here’s how to do it.
