ExpressVPN is a secure Mac VPN client for Mojave, High Sierra, Yosemite, Mavericks, and all previous macOS. Unblock the internet in one. To connect to your Mac, Windows users need the network address for your Mac, and a user name and password to use to log in to your Mac. To find your Mac computer’s network address, choose Apple menu System Preferences, click Sharing, then select File Sharing. The address appears below the “File Sharing: On” indicator, and looks similar to this example: smb://17.212.167.33/.

Apple began transitioning to 64-bit hardware and software technology for Mac over a decade ago, and all modern Macs now include powerful 64-bit processors that can run advanced 64-bit apps. These apps can access dramatically more memory, enable faster system performance, and take advantage of technologies that define today's Mac experience, such as Metal graphics acceleration.

Apple has been working with developers to transition their apps, and in 2018 Apple informed them that macOS Mojave would be the last version of macOS to run 32-bit apps.

Apple's transition to 64-bit technology is now complete. Starting with macOS Catalina, 32-bit apps are no longer compatible with macOS. If you have a 32-bit app, please check with the app developer for a 64-bit version.

Opening 32-bit apps

When you attempt to open a 32-bit app, you will see an alert that the app needs to be updated to work with this version of macOS, or that the app is not optimized for your Mac and needs to be updated.

macOS Catalina

macOS Mojave and macOS High Sierra

If you haven't upgraded to macOS Catalina, you can still open and use the app, but you should check with the app developer for a 64-bit version that also works with the latest macOS.

How to find 32-bit apps on your Mac

System Information can find 32-bit apps that are installed on your Mac:

1. Choose Apple menu  > About This Mac, then click the System Report button.
2. Select Legacy Software in the sidebar. All legacy software is 32-bit.
3. If you don't see Legacy Software in the sidebar, select Applications in the sidebar, then check the list of apps on the right. The column labeled ”64-Bit (Intel)” shows ”No” for apps that are 32-bit.

When upgrading to macOS Catalina, the installer shows a list of recently used apps that are 32-bit. You can review this list before choosing whether to cancel or continue the installation:

macOS Catalina also shows a prohibitory symbol over the icon of each 32-bit app in the Finder, letting you know that the app will not open.

How to contact the app developer

The developer (or vendor) is the person or company that made the app. The easiest way to find contact information for an app's developer is to search the web for their name or the name of their app. Learn more about contacting third-party vendors.

To find the name of the developer:

1. Select the app in the Finder.
2. Choose File > Get Info from the menu bar.
3. Look for copyright information in the Info window. For example, Apple is the developer of this app:
