32 vs 64 bit app

I keep receiving this pop up "app is not optimized for this Mac and needs to be updated". Should I NOT update my computer being that Adobe apps are not 64 bit apps? Will this be converted so that we can still use the programs we pay for on our new iMacs???

PLEASE advise asap as my computer wants to do an update, but I keep declining as I am fearful that my apps will not longer work.

Thanks

Everyone will be upgrading to 64 bit apps eventually, if you want to keep using future Mac operating systems. Apple insists on it. But this message is currently more for developers like Adobe than end users. For now, it's awareness for end users and a call to action for developers.

There will come a day when Apple stops 32 bit support completely. On that day, you stop updating your Mac operating system if you cannot live without your 32 bit app and there will never be a 64 bit version of it. If all your apps are 64 bit on that day then you'll be fine. But we're not there yet. Might be in 2019 or 2020. No-one knows the final date, not even Apple yet. We're in a very long grace period.

Apple's statement on the issue:

32-bit app compatibility with macOS High Sierra 10.13.4 and later - Apple Support

This warning (nag screen) will appear every 30 days when you launch a 32 bit app in Mojave. There is nothing for end users to worry about yet. It's part of Apple's decade long campaign to drop support for 32 bit apps. In this case, the ball is in Adobe's court to issue 64 bit versions of their apps - before Apple disables them entirely in the operating system. Adobe is no doubt working on it.

So update your computer and carry on as normal for now.

Are you running old versions of Adobe apps (Creative Suite) rather than subscription (Creative Cloud)? If so, don't upgrade Mac OS as most old apps WON'T RUN in future.

Adobe is aware that Apple is planning to stop running 32bit programs

For now, unless your Apple message is that a 32bit program WILL NOT RUN you are only seeing a warning
