Jan 22, 2019 “Microsoft Office Utilities” is not optimised for your Mac and needs to be updated. Does anyone know how to resolve this issue I have, The above message keeps coming up when i log in to my iMac. May 25, 2018  To see a list of which of your Mac apps are 32-bit, and therefore not optimized for your Mac, without needing to launch every app, you can turn to the handy System Information window. To use it, start from your Mac desktop and then click once on the Apple icon in.

Apple was phasing out the use of 32-bits applications on macOS for quite some time. Now the finishing time has come that the version 10.15 or macOS Catalina will no more support 32-bit applications. If you are still running old and unsupported applications in macOS Mojave or earlier versions then you need be cautious before upgrading to macOS Catalina. In this article, we will explain how to check 32-bit and 64-bit apps in macOS.

What Happens When You Open 32-bit Apps?

As of macOS Mojave, Apple will show a warning message whenever you open 32-bit apps. The best example of 32-bit app on macOS is Microsoft Office 2011. Whenever you open the app, macOS will show you a message like below indicating that the app is outdated and not optimized for your Mac.

However, you can still click on the “OK” button to continue using the app. Unfortunately, this is no more possible with macOS Catalina. When the 32-bit app is on the dock, you will see a white cross mark on the app indicating it will not work any more.

Trying to open the 32-bit with macOS Catalina will show a messages like below depending on the app:

Basically you have the following three options:

• Go to the App Store and find the replacement or upgraded app.
• Click on “Learn More…” button to go to Apple’s page explaining about 32-bit apps.
• Choose “Not Now” button to close the app.

If there are no upgrade or alternate options then you can’t use 32-bit apps with macOS Catalina.

How to Check 32-bit and 64-bit Apps in macOS?

If you wanted to check how many apps on your Mac are running with 32-bit then follow the below instructions.

• Click on the Apple menu icon on top left corner of the Mac and choose “About This Mac” option.
• Under the “Overview” tab, click on “System Report…” button.

• You will see a system information dialog like below. Click on the “Applications” option available under “Software” section. It may take sometime to load the list depending upon the number of apps on your Mac.

• Select any application to view the details on the below pane. You can check against the “Kind” option whether it shows 32-bit or 64-bit apps.
• Generally, all Apple apps should be of 64-bit. Therefore, you can click on the “Obtained from” column to sort the list based on the developer.
• Check the apps downloaded from Mac App Store, Identified Developer or Unknown categories to easily find the 32-bit apps.
• You can clearly see the Kind will show as “32-bit (Unsupported) indicating the app will no more work on your Mac.

Taking Action

Unfortunately, you have no option to modified any parameter on the apps. If you have premium apps purchased from App Store or directly from third-party websites, contact the developer and inform them to upgrade a 64-bit version. For the free apps, you need to find alternatives from App Store from other developers.

If you have no other option to use the app then delay upgrading to macOS Catalina till the time you find alternative solution.

The Mac has been shipping with 64-bit processors since before the Intel transition and macOS, née OS X, has supported 64-bit for years. Modern technologies, like Metal, require 64-bit. One day, macOS will as well. Apple hasn't said what day that will be, at least not yet, but it's continuing its long, slow march in that general direction.

At WWDC 2018, Apple noted that macOS Mojave will be the last Mac operating system to support 32-bit apps. By fall of 2019, and possibly sooner, any 32-bit apps still on your Mac will no longer work.

Apple has been notifying Mac users since April 2018. If you open an app on your Mac and get an alert that an app isn't optimized, there are a few things you can do.

What notification will Mac users see?

If you're running macOS 10.13.4 or later, starting April 12 at midnight local time, if and when you launch a 32-bit notification, you'll get a notification that says:

[App] is not optimized for your Mac.

This app needs to be updated by its developer to improve compatibility.

You'll only ever get the notification once — the first time you launch the 32-bit app, and only to let you know the app will, eventually, be outdated.

Will you still be able to run 32-bit apps on macOS?

Absolutely. For now — and until Apple officially announces and implements an end-of-support date or the next Mac operating system launches, whichever comes first.

Is there a way to see any and all 32-bit apps you might have installed on your Mac?

There is, but it's tedious.

1. Click on the Apple icon in the Menubar.
2. Click on About this Mac.
3. Click on System Report.
4. Click on Applications (under Software.)
5. Click on an App.
6. If the 64-bit (Intel) field says No, the app is 32-bit.

What do you do if you have 32-bit apps?

Check the Mac App Store or developer's webpage for an updated, 64-bit version of the app. If one's available, upgrade.

If there's no 64-bit version available, you can send the developer feedback, or you can look for a similar app that does support 64-bit.

When will the 32- to 64-bit transition be complete?

Apple hasn't set that date yet. Hopefully, the company is watching how fast developers are moving and users are updating and, when it does set a date, it'll be one that works for as many people as possible. The only thing we know so far is that Apple has confirmed that macOS 10.14 Mojave wil be the last macOS to support 32-bit apps.

For more information, keep an eye on Apple's knowledge base.
