We’re about a month away from Apple announcing the next version of its desktop and laptop operating system, macOS. Although there’s often lots of excitement and anticipation for Apple’s latest software, it’s also a time of trepidation as apps and back-end services people rely on may no longer work. If you’re a Mac user and like to update early, there are some things you can do now to ease the pain of transition.
Identify your 32-bit apps
For the last couple of years, Apple has been paving the way for 32-bit apps to disappear.
macOS 10.13 supported 32-bit apps but macOS 10.13 and 10.14 (High Sierra and Mojave respectively) popped up a warning letting you know you have a legacy app.
If you aren’t sure whether you have any 32-bit apps left on your Mac you can easily check.
- From the Apple menu in the top-left corner of your system, click on the About this Mac menu item
- Click the System Report button
- Scroll down the list of items on the left side until you spot Applications (it’s in the Software section
- Click on Applications and a list of all your installed apps will appear. It may take a few seconds for this list to appear so be patient
- Look down the 64-Bit (Intel) column. Any app with a “No” is 32-Bit and isn’t likely to be useable when macOS 10.15 is released later this year
Not all 64-bit apps will just work
It’s possible that some 64-bit apps won’t work when you upgrade.
Apple often changes the underlying foundations of its software and there’s wide speculation a number of older macOS components will be deprecated.
Dashboard isn't the only thing gone in 10.15 — so is 32-bit app & plugin support, Carbon, Ink, QuickTime 7 & QuickTime plugins, PPTP, and hardware RAID. You will get Python 3.7 and Ruby 2.6, at least ????

My rule is to move away from any application that hasn’t been updated in over a year or so – especially if the developer has been quiet about updates.
Make a plan
If any of your apps are 32-bit, which is possible if you’re holding on to old favourites or rarely update your software, then you need to decide whether upgrading to macOS 10.15 is for you or start updating to more recent releases now.
Software developers have been aware of this change for about three years so, unless an application has been abandoned, superseded or formally deprecated there should be an upgrade path.
In some cases, this is likely to come with a financial cost. I know a few people hanging on to old versions of Photoshop and Filemaker for whom this kind of update will be massively painful.
The best of both worlds
If you want to experiment with the latest version of macOS without compromising your main working system, yo do have a couple of alternatives.
If you have a second Mac, you can upgrade that and test out new apps and services.
While many of us are happily living a monogamous life when it comes to the operating system we use on our computer, there are times when being able to run another OS is helpful. If you're a Mac user, there are several options for running other operating systems virtually.Read more
Then you can install the new OS in a virtual machine, try things out and, if you’re happy, upgrade your core system.
