On May 29, 2026, MC Federal Credit Union released version 3.34.1 of our Mobile Banking app for Apple (iOS) devices. To continue using the Mobile Banking app, iPhone and iPad users must update to the latest version of the app.
The new app requires iOS 18.4 or later. If your device cannot be updated to iOS 18.4, you will no longer be able to access the MC Federal Mobile Banking app. Generally, iPhones older than the iPhone 11 and iPhone SE (2nd generation) are not expected to support this version of iOS.
If your device is set to update apps automatically, the update may have already been installed. If you are experiencing issues accessing Mobile Banking, please verify that both your app and iOS operating system are up to date.
For members with unsupported devices, access to Digital Banking through a web browser may still be available. To access your accounts, visit mcfcu.org and click the Digital Banking button.
Android devices are not affected by this update at this time. However, we recommend keeping both the Mobile Banking app and Android operating system updated to the latest available versions.
