Tahoe update causing a lot of glitches!
Subject: Multiple Display, Input, and Audio Issues After Updating to macOS Tahoe (2019 MacBook Pro)
After updating to macOS Tahoe (version 15.0) on my 2019 MacBook Pro (16-inch, Intel Core i7, 16GB RAM) about three weeks ago, I’ve been experiencing persistent glitches affecting the display, input, and audio.
Display Issues
- I can no longer maximize application windows (e.g., Firefox, Pages).
- The right third of the display is unresponsive to the cursor — I can’t scroll, click, or select anything in that area.
- When I attempt to interact with the right side, other applications open automatically or the display dims unexpectedly.
- I’ve had to resize all windows to fit on the left two-thirds of the screen as a workaround.
- Restarting and resetting the NVRAM/PRAM and SMC did not resolve the issue.
Input and Accessibility Issues
- I use the Accessibility Keyboard as my primary input method.
- Frequently, when I try to type in the Messages app, the keyboard becomes unresponsive, and documents from my desktop open automatically.
- To temporarily fix it, I must:
- Hide the Accessibility Keyboard.
- Close all open applications.
- Click on the desktop.
- Reopen the Accessibility Keyboard.
- This issue has been occurring consistently for approximately two weeks.
Audio Issue
- As of today, I’ve noticed repeating or echoing system sounds when sending messages, adding reactions, or playing videos in the LINE app.
Troubleshooting Steps Tried
- Restarted the laptop multiple times.
- Reset NVRAM/PRAM and SMC.
- Verified that macOS is updated to the latest version of Tahoe.
- Checked for any third-party extensions or login items — none active.
Question
Could these issues be related to the Accessibility Keyboard or display input management under macOS Tahoe? Has anyone else experienced similar behavior after upgrading?
