“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.
If you get a bit bored booting up your Mac and waiting for the Apple logo, here’s a trick that will let you see what’s going on behind the scenes. It’s called verbose mode and it simply echoes to your screen everything that the computer is doing while it boots up. It doesn’t change anything about the way the computer operates, it doesn’t speed it up or slow it down, it just displays it on the screen.
To enable “Verbose mode” go into the terminal (Applications/Utilities/Terminal) and type in the following line:
Apple used to have a fantastic application called OSX Server (now called MacOS Server) which allowed you to run a full server from any OSX computer. A server can allow you share files, run your own email or web server, remotely connect in to your office etc. OSX server was particularly powerful running on a Mac Mini. With OSX Mojave Apple killed off OSX server, but it is still possible to download an older version from Apple that still works. Here’s how.
If you get a warning like this be very careful about clicking ‘Allow.’ I’ve noticed that lots of websites have been asking to send me notifications. What you may not realise is that these notifications do not come through your web browser. They come through the OSX built-in notifications that appear on the right of your screen. This means that the notifications can appear when you’re working in a word processor, typing an email, anytime! What’s worse is when a notification pops up there is no simple way to turn it off. You can dismiss it as read, but you can be sure you will get another notification from that same website pretty soon. I personally find this quite intrusive and it gets very annoying.
To turn off these notifications you need to go into your ‘System Preferences’ and then click on the notifications tab, then scroll down to the website that has given you the notification, and delete it. There will be an entry in the notifications settings for any time you have clicked ‘Allow’ – you need to go and delete them all one by one. It’s quite a process!
Once you have accepted a notification from a website in order to stop it you need to go into system preferences and notifications and delete it.
Apple as usual have been putting out software updates regularly, but some of them are very big. Software update 10.13.5 is over 2GB and 10.13.4 was 2.5GB. We have 4 Macintosh computers in our household so when they each download it, that ads up to approx 10GB of downloads. This is not a problem if you are on unlimited internet but if you have a small plan or if you are using your mobile phone hotspot for internet this can chew through your downloads pretty quickly!
Did you know that you can download the update once then copy it across to each computer by hand to save space? Here’s how.
On October 31 Apple released the first update to High Sierra, OSX 10.13.1. There were a few teething issues with High Sierra 10.13 so the release of 10.13.1 might be a good time to upgrade.
My ‘Software Update would not find High Sierra or the upgrade. I went to ‘Software Update’ only to be told ‘No Updates Available.’ If this is the case for you, you can download High Sierra manually by going to this link:
