Watch out for Catalina!

I was asked last week about a message that had appeared on a Lightroom 4 users’ screen with this warning …

… scary eh!?

Well yes it is but if you’ve got a relatively new Mac you do have the choice NOW of making sure you have the latest version of software that will support older versions of Lightroom, and do an upgrade to Mojave (v.10.14) BEFORE Catalina (v.10.15) is released later this year – probably in October. That way you’ll be nearly up-to-date with your version of MacOS and that may be sufficient for you if you don’t feel the need to have the latest version of MacOS.

If you have Lightroom 6 installed (or even 3, 4 or 5), you may be getting the message above EVEN THOUGH it is a 64-bit app. This is because the Installer/Uninstaller and Activation code software is 32-bit. That means the software “should” continue to work, but you won’t be able to re-install it to a MacOS of Catalina (v.10.15), or later.

The only other alternative if you want to stick with Adobe Lightroom is to swallow hard and subscribe at £9.98pm to the Photography Plan of Adobe’s Creative Cloud programme. You do get Photoshop as well as what Adobe call Lightroom Classic, plus their in the cloud version of Lightroom which they (confusingly) call Lightroom!

Adobe detail the changes and implications in this blog post. Another post from Laura Shoe Training gives more information here.

UPDATE: I’ve just read this really useful and interesting article from the magazine MacWorld – I suggest you read it too – and I’ve found out that Microsoft 2011 for Mac and Picasa (amongst others on my iMac) will not work with Catalina. Whilst I’m not particularly concerned about losing either of these as there are alternatives I’m already using – such as (in the case of the former) Google Docs, Open Office, Libre Office or Apple’s Pages, Numbers or Keynote applications – it’s better to be prepared and to have made the decision to move before I have to jump! Also in the case of Picasa, that I haven’t got anything in the database that I haven’t catalogued elsewhere – I think that unlikely, but I ought to check!

I’ve also stumbled upon an entry in “About This Mac > System Report …” which you get to from the Apple Icon in the top-left corner of your desktop. Go to Software and if you’re running Mojave there’s an entry called Legacy Software. Look at that and you’ll be able to see quickly what software is unlikely to work in Catalina. If you’re running an earlier version of MacOS go to Software and click on Applications and look for non 64-bit applications (a column to the right of the window).

PS I’m still running Mojave [16th April, 2020] on desktop and laptop.

Beware the free upgrade

So … we’re all excited about the advent of iOS 11 for our iPads and iPhones aren’t we? Or we are if our devices can actually take the new operating system. And there’s the first challenge. Apple gives us free upgrades to its operating system software but it comes at a price in terms of the pensioning off of some hardware from ongoing support.
So, if you don’t have any of the hardware on the list below … stop reading this post and go and do something constructive.

So what’s wrong with iOS 11, nothing of course, it looks like a really feature-rich release with lots of goodies to enjoy and reports seem to suggest that it doesn’t slow down your device significantly … except it’s a wholly 64-bit operating system. This means that all applications that you run on the device must be written in code that runs on a 64-bit operating system, and the problem is that quite a few of your applications, even some you really like, may have been written using older 32-bit code. You may even have noticed some alerts coming up on your screen to say “contact the developer” when you’ve been running an application – that’s the reason for the alerts – your app is potentially going “end of life”. So … before you do the automatic upgrade just do these checks.
Goto Settings > General > About and you will see something like this …

… click on Applications, and something like this will be shown …

… read the warning message at the top of your screen carefully. What it is saying is that these apps are written in 32-bit code and will tend to run slower than if they were written in 64-bit code. What is more, they will stop working with iOS 11. Then clicking on any of the apps shown on your iPhone (similar to the ones above on my iPhone), will give you this screen message which effectively says that the app is end-of-life UNLESS the developer provides a 64-bit version.

Now most of these apps on my iPhone I can probably do without but I do know that I ought to approach Cardiff Bus to find out when their 64-bit version of the Timetable and Journey Map is going to be released, as I use that a lot!
