Recently Apple revealed support for 32-bit apps on macOS will soon be phased out of the operating system. Users on the latest version of the OS are seeing a warning dialog when opening 32-bit apps. You probably have some 32-bit apps on your computer. This article will show you how to check for 32-bit apps on your Mac.

In a recent blog post, my colleague Kayla Myrhow did an excellent job explaining the 32-bit application issue for users who are considering or have already moved to macOS® Catalina. In this post, I’ll show you how to set up your Mac® to continue to run 32-bit apps. You can do this either before or after you upgrade to macOS Catalina.

There are only two steps, but it does take about 45 minutes to complete this setup:

1. Create a Parallels Desktop® for Mac virtual machine and install an older Mac operating systemin it.
2. Install the 32-bit apps you wantinto this new virtual machine.

1. Oct 12, 2019  Apple first announced that it would ultimately wind down support for 32-bit apps more than a year and a half ago, when it began pushing alerts to macOS High Sierra users that 32-bit.
2. Jul 24, 2019  How do I check for 32-bit apps on my Mac? Older Microsoft apps will no longer function and require updating. By default, macOS will send you a dialog box if you attempt to open a 32-bit app in macOS Mojave. The popup will say that the app is “not optimized for your Mac,” or something similar.
3. Sep 14, 2019  However with the release of Mac OS 10.15 later this year, no 32 bit apps will work. To avoid issues, you could leave your computer at it’s existing Operating System. If you do decide to upgrade, you will need to determine which app is not compatible, and check with the developer of that app to see if they have, or have plans of providing a 64.

I made a videoof this entire process—I edited out the boring parts but left all the essentialsteps. The end result is the 5-minute video below. For this video, I chosemacOS High Sierra as the older Mac OS, but you could install Mojave, Sierra oralmost any older Mac OS. I also chose the Office for Mac 2011 suite as the32-bit application, because several users have told me that it contains the setof 32-bit apps that they most want to run in Catalina.

After you finish this setup, you will be able to run 32-bit apps on your Mac running macOS Catalina.

Try Parallels Desktop for free for 14 days and run 32-bit apps on your Mac.

Let us know inthe comments which 32-bit apps you need to run on macOS Catalina and how thisis working out for you.

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.

On a Mac, everything is designed to work just the way you expect it to — from operating it with simple, intuitive gestures to asking Siri to find a file to having your apps automatically update themselves. Whatever you set out to do on a Mac, there’s much less to learn and that much more to accomplish. Oct 18, 2019  If any updates are available, click the Update Now button to install them. Or click ”More info” to see details about each update and select specific updates to install. When Software Update says that your Mac is up to date, the installed version of macOS and all of its apps are also up to date.

How to enable Instant Hotspot on your iPhone or cellular iPad. Launch the Settings app from the Home screen of your iPhone or iPad. Tap on Personal Hotspot. How to find software update on iphone. Update your Software Old software can cause connection issues. This is especially true when you try to connect a newer iPhone model to an older Mac or PC. Updating both your iOS and iTunes could fix the problem. Here’s how to update iTunes on your Mac. Click “iTunes” on the Apple Menu bar and then click “Check for Updates”. Aug 15, 2019  A 2015 MacBook Air can be upgraded to Mojave. The reason you are not finding anything in Updates is because it is not an update but rather an Upgrade. Get macOS Mojave. Be sure to make a TIme Machine backup before upgrading. Also check for third party app compatibility here: https://roaringapps.com.

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.
