So there are a lot of reasons why you should keep your software updated. They could still use it but at some point they should update. They don't want to spend the money on it and now they find out that this old version gives them this message sometimes. They're trying to use an old version say of Microsoft Word or something and they don't want to update to the newer version. That's the most common thing that people have now. So you're using an earlier version even though newer versions have come out. Or perhaps they have updated their app but you failed to follow those updates. Maybe the company doesn't even exist anymore. They haven't created a new version for awhile. The developer is no longer updating the app.
#APP IS NOT OPTIMIZED FOR YOUR MAC 64 BIT#
So if a developer failed to update their app over all those years and kept it as a 32 bit app, then you could still run it.īut at this point the only apps that are still 32 bit only and not compatible with 64 bit are apps that have been abandoned. But for a long time, and up till now, Macs can run both. So any Mac you bought from 2010 on, as a matter of fact even a little bit earlier than that, could run 64 bit apps. So you needed a 64 bit Mac to be able to run Lion.
#APP IS NOT OPTIMIZED FOR YOUR MAC MAC OS#
As a matter of fact in 2010 when Mac OS Lion came out that operating system was 64 bit. Now, Macs have been 64 bit for a long time. So why is this happening? Well, if an app gets very old without being updated it's still in 32 bit mode. It's just warning you that the next thing to come after Mojave won't. So, as long as you continue using Mojave you will be able to use this app.

Not the next small release or update or something like that. So probably what comes out later this year probably in the Fall. By the future it means the next version of Mac OS. This says this app will run and you can still use it. The first misconception people have is when they see this is now my app is no longer compatible with my Mac. So operating systems can handle 32 bit apps or 64 bit apps or both.

Now the operating system has to be able to understand the type of app. 64 bit apps is the modern way to make apps. So 32 bit apps are older style apps, probably made years ago using older development software. What this means is that the app that you're trying to run isn't 64 bit. A lot of people talk about these online and there's a lot of misinformation out there. Video Transcript: A lot of people have noticed messages like these since upgrading to Mac OS Mojave.
