I wanted to print a large Christmas banner and the printer wanted an image file (png or jpg). Our file was in a pdf format. I needed to convert the pdf file to a very high resolution png file so that it would look good on a large banner. Here’s how to do it using Apple’s built in Preview app.

This article is a bit technical. I have an office at home but I wanted to be able to log into the church computer to control it remotely, upload files, and also print to the printer there. Here’s how to do that.

An apology to international readers – some of the details in this post apply specifically to Australia, although there will be principles here that you can apply. I live just 5 km line of sight from a regional Australian city and our internet comes by ‘fixed wireless.’ Fixed wireless is essentially a dedicated 4G connection with a local directional antenna. The problem is that most of the towers are oversubscribed, and upload and download speeds are very poor. (5Mbps down and 1Mbps up).

My experiment

For the past 3 months I’ve been experimenting with various configurations of 4G carriers and modems to tweak the maximum speed I can from the 4G data network. The results have surprised me!

I have been upgrading RAM in Apple computers since my first Mam, an LCIII, back in the 1990’s. I’ve pulled apart iPods to replace the battery, I’ve pulled apart iMacs with their glass screen and I’ve changed the hard drive and screens in macbook pro’s. But the hardest gig yet was changing the memory in my 2018 Mac Mini.

After my first attempt I rebooted my Mac to discover that one of the RAM modules was not working. This is the first time this has ever happened to me. I needed to pull the whole thing apart again give the RAM modules a jiggle and then reassemble the Mac mini. Read on to find out more about my experience!

Last month I described a bug in Apple Pages which caused Pages to place hidden color information in greyscale documents. This is fine if you are printing at home but if you take those documents to a commercial printer you will be charged at color copy rates instead of black and white. At our local Officeworks store this means paying 65 cents per page instead of 8 cents.

Today Apple support contacted me to say that they are very sorry but that this is not a bug. It is the way the software was designed. Apple Pages cannot print a greyscale document. It can only print in color. They suggested that I could put in a ‘feature request’ to request that Pages print in greyscale.

This is outrageous. Apple in its software clearly gives the impression that it is printing in greyscale. When users discover the extra costs they have been incurring this potentially opens Apple to litigation. The color selector tools in Pages are clearly misleading. Let me explain.

I’ve never done a movie review before, but this looks great. It’s the story of some people who left Apple and tried to invent a smartphone… and failed… but paved the way for lots of other technology. Looks very interesting.

It is against the YouTube terms and conditions to download a video from YouTube and put it into your Keynote presentation. But if you have the author’s permission you are allowed to stream a video from Youtube. The only way I know to do this is using a free application called ‘LiveSlides’

You can download the live slides application from here:

https://www.liveslides.com/download/mac

1. Open your presentation in Keynote.

2. Open Safari and get the Video URL

Open the video in your web browser – go to Youtube, open the video and right click and select ‘Copy URL’

3. Run LiveSlides

Launch ‘LiveSlides’ and paste the URL (Apple – V’ )into Liveslides. Liveslides will put the link for the live video into Keynote.

Now when you play your keynote presentation, it will download the Youtube video live from the Internet and play it.
