macOS 10.15.5 is an update to macOS 10.15 (Catalina), released on May 26, 2020 by Apple Inc.

New features

This update adds the following features:

Battery Health Management:

  • Battery Health Management to help maximize battery lifespan for Mac notebooks.
  • Energy Saver preference pane now displays battery condition and recommends if the battery needs to be serviced.
  • Option to disable battery health management.

FaceTime Prominence Preference:

  • New option to control automatic prominence on Group FaceTime calls, so video tiles do not change size when a participant speaks.

Calibration Fine-Tuning for Pro Display XDR:

  • Controls to fine-tune the built-in calibration of your Pro Display XDR by adjusting the white point and luminance for a precise match to your own display-calibration target.

This update also includes bug fixes and other improvements:

  • Fixes an issue that may prevent Reminders from sending notifications for recurring reminders.
  • Addresses an issue that may prevent password entry on the login screen.
  • Fixes an issue where System Preferences would continue to show a notification badge even after installing an update.
  • Resolves an issue where the built-in camera may not be detected when trying to use it after using a video conferencing app.
  • Addresses an issue for Mac computers with the Apple T2 Security Chip where internal speakers may not appear as a sound output device in Sound preferences.
  • Fixes a stability issue with uploading and downloading media files from iCloud Photo Library while your Mac is asleep.
  • Resolves a stability issue when transferring large amounts of data to RAID volumes.
  • Fixes an issue where the Reduced Motion Accessibility preference did not reduce the speed of animations in a Group FaceTime call.

Enterprise content:

  • Improves performance on certain Mac models when enabling hardware acceleration in GPU-intensive apps such as those used for video conferencing.
  • Addresses an issue where Microsoft Exchange accounts were unable to sign in during account setup when using Conditional Access.
  • Apple Push Notification Service traffic now uses a web proxy when specified in a PAC file via the Proxies payload.
  • Resolves an issue that prevented some displays connected to MacBook Pro (16-inch, 2019) from waking from sleep when the Mac wakes.
  • Major new releases of macOS are no longer hidden when using the softwareupdate(8) command with the --ignore flag. This change also affects macOS Mojave and macOS High Sierra after installing Security Update 2020-003.

Other issues

Former Apple employee Mike Bombich found that macOS 10.15.5 will incorrectly report success in creating a bootable backup of an APFS volume to third party backup applications when actually failing.[1] This issue was first identified during beta testing and was not addressed in the public release. Apple has not yet confirmed whether this is a bug or an intentional change as Apple had previously suggested at WWDC 2019 that developers should use Apple's own Apple Software Restore (ASR) utility.[2]
