“This Program can’t be opened because it is from an unidentified developer”
Apple are getting tighter on which software they allow you to run on your computer. This is good because it avoids you getting any malware on your computer from bad software developers. But it also means that some legitimate software won’t run. If you are trying to download software from somewhere other than the Apple app store and you trust the source you are downloading your software from, here’s how to manually turn on the security settings for it to run.
In OSX Catailna Apple have introduced lots of security ‘Features’ which make it harder to install and run software, especially with software that interacts with other applications.

In this document I write about how to edit a PDF file using the built-in OS X preview app. But sometimes you need to add your signature to a PDF document. Well here is some good news – you can also sign a document right from within the preview app. Thanks to Bryson who pointed this out to me!
1. Firstly click the pen symbol as if you were going to edit the PDF file.
2. Then click the ‘create signature’ button.
3. Sign using the track pad or camera.
If you select “trackpad” you will be able to use the trackpad on your MacBook to sign your signature and the app will record your signature and keep it in preview for signing future PDFs.
If you select “Camera” you just need to sign your signature on a piece of paper in panel pencil and then hold it up in front of your computer’s camera. Preview will automatically adjust your signature and scan it.
Now you can just select your signature and preview will insert it into the PDF document when you need it.
Your signature will automatically be stored in preview so that you can use it in the future, but if you want it deleted for security purposes you can simply click on the cross on the right-hand side of your signature and it will delete it.
News.com.au today published an article encouraging people to change their email passwords. The article begins “The email addresses and passwords of 771 million people have been published online during a gigantic data leak”. This is not exactly correct. What has happened is that login information from various companies has been hacked into over the years, and it seems that some of that has been published in a massive document recently. This includes people’s login details from companies like Adobe, Dropbox, Kickstarter and more.
So it is not your email password that has been leaked, it is your login email address and password for those websites. Read on to find out if your email address was involved.
