Aug 14, 2017 iOS How to change your app from 32 bit to 64 bit in Xcode. If you have made projects after May 7th 2012 your apps projects already support 32 bit and 64 bit.
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.
Air force cac card reader software mac update. 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the notification once — the first time you launch the 32-bit app, and only to let you know the app will, eventually, be outdated.
Run 32 Bit Application In 64 Bit
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.
- Click on the Apple icon in the Menubar.
- Click on About this Mac.
- Click on System Report.
- Click on Applications (under Software.)
- Click on an App.
- 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.

Google faces privacy lawsuit over tracking users in apps without consent
Law firm Boies Schiller Flexner has filed another lawsuit against Google. This time, the law firm has accused Google of tracking users in apps even after opting out.
When macOS Mojave was announced, Apple warned that it would be the last version of macOS that would support older 32-bit apps. Apple has been phasing out 32-bit apps for the last 10 years and is now ready to take the final step, even if Mac users may not be ready to lose access to older apps.
With the release of macOS Catalina, 32-bit app support is no longer available, which means many of your older apps will no longer work if they haven't been updated to 64-bit.
32-bit vs. 64-bit
32-bit apps date back to a time when there were 32-bit processors and 32-bit operating systems, but are now outdated. Apple has long since transitioned to 64-bit processors and macOS has been 64-bit since the launch of Snow Leopard in 2009.
Compared to 32-bit apps, 64-bit apps can take advantage of more memory and offer faster system performance. Apple technologies like Metal only work with 64-bit apps, and for Apple to ensure that Mac apps include all of the latest advancements and optimizations, support for 32-bit needs to end. In the simplest terms, 32-bit apps are inefficient.
32-bit apps can run on a 64-bit system as they've been doing for years, but Apple wants to get rid of outdated apps to make sure everything that runs on the Mac is properly optimized and isn't an unnecessary drain on system resources.
Apple started warning Mac users about plans to end support for 32-bit apps back with macOS High Sierra. In High Sierra, users started getting warnings about a 32-bit app's future incompatibility with macOS.
A similar message was available in macOS Mojave, and if you opened up a 32-bit app while running Mojave, you saw an alert letting you know a specific app wouldn't work with future versions of macOS unless it was updated.
Alerts re-appeared every 30 days when launching an app, with Apple aiming to make sure customers would not be caught unaware when a 32-bit app stopped working in the future, so you should already know if one of your frequently used apps hasn't been upgraded to 64-bit.
Upon updating to macOS Catalina, you'll be shown a list of 32-bit apps that no longer work on your system.
How to Check if an App is 32-Bit or 64-Bit in macOS Mojave
To determine whether an app is 64-bit or 32-bit and to see if there are 32-bit apps installed on your machine before upgrading to macOS Catalina, follow these steps:
- Click the Apple symbol () in the menu bar on your Mac's desktop.
- Click on About This Mac.
- Choose 'System Report' at the bottom of the window.
- Scroll down to the Software list on the sidebar.
- Select Legacy Software.'
Anything in the list of Legacy Software applications is a 32-bit app and will not work when upgrading to macOS Catalina.
If Legacy Software isn't an option in the sidebar, select the Applications option and then check the list of apps at the right. The column that's labeled 64-bit will show a 'No' listing for apps that are 32-bit.
How to Prepare to Update to macOS Catalina
The first step is to make sure there aren't already available updates for apps that you have on your system, which you can generally do by updating through the Mac App Store for Mac App Store apps.
Apps outside of the Mac App Store use other update methods that can vary by app, but for many, you can click on the app's name in the menu bar and choose the 'Check for Updates' option. Some other apps have more hidden update methods, so if you do have a 32-bit app, make sure to Google how to update it to be sure there's not already new software available.
After ensuring you've updated everything you're able to update, you can contact developers and ask them to update their apps, but if that doesn't pan out, the only other solution is to start the search for an alternative app if you're committed to upgrading to macOS Catalina or have already done so.
32-Bit App Warnings When Installing Catalina
When upgrading to macOS Catalina, the installer will show a list of recently used apps that are 32-bit so you know what to expect before installing.
After viewing this list, you can choose to either cancel or continue with the installation.
macOS Catalina also shows a stop symbol over the icon of 32-bit apps in the Finder, so you know that the app isn't going to open.
With the release of macOS Catalina, Aperture is going to stop working. Apple warned Aperture users in April 2019 that the software won't run in future versions of macOS, starting with macOS Catalina.
If you're an Aperture user, you'll have to transition to alternate photo editing and management software, such as Adobe's Lightroom. Aperture is not 32-bit, but Apple is phasing it out all the same.
Affected Media Formats
Certain media files that use older formats and codecs are also not compatible with macOS after macOS Mojave due to the 64-bit transition, and you will need to convert some iMovie and Final Cut Pro X libraries. Incompatible media files were created using codecs that rely on QuickTime 7, and while macOS Mojave has QuickTime 7 frameworks, future versions of macOS will not.
Apple has a full list of media formats that are going to be affected by the transition available in a support document.
Continuing to Use 32-Bit Apps
In macOS Mojave and earlier versions of macOS like High Sierra, you can continue to use your 32-bit apps. If you have a 32-bit app that you absolutely depend on, you're going to want to think twice before upgrading to macOS Catalina.
