32-bit app to 64-bit app

I want to update my mac to Mojave. However, I can't update Mojave because there's an issue launching 32-bit app. How can I update 32-bit app to 64-bit app so that I can update my mac?

Looking forward to your response.


Thanks.

macOS Mojave can run 32bit and 64bit apps

later macOS's such as Catalina, Big Sur and beyond will only run 64bit apps.


Which app is it.

Go to the app developers website and see if they provide a version of the app

that will run on macOS Mojave.

With the release of macOS 10.15 Catalina—


There is a generic warning. Typically you have to do nothing, developers will issue 64-bit version of there software if they want them to continue to run.


Update the macOS update your third party software.





Always advise to have current backup plan—only in this way can you fall back, if there is something mission critical you can not live without.

Depends on what apps you're talking about. High Sierra was the last version of macOS that would run 32 bit apps without compromise (Apple's words). Mojave isn't as forgiving. Such as, Office 2011 ran reasonably well in High Sierra, but it was essentially luck if it would run at all in Mojave.


In another example, I have the CS6 Master Collection installed on a Mojave partition of my 2018 Mini. After Effects wouldn't run even after applying all updates through its own updater. BUT! If you downloaded the same point release updater from Adobe's servers and applied it, then After Effects worked.


In short, it's kind of a crap shoot what 32 bit apps will run, and what won't.
