To isolate the issue, boot your Mac into Safe Mode by holding the Shift key during startup. In Safe Mode, only essential system processes run, allowing you to test if the freezing persists. If the problem disappears, systematically disable or uninstall recently added applications to pinpoint the offender.
For persistent issues, resetting the System Management Controller (SMC) and NVRAM/PRAM can help. These components manage hardware settings, and corruption in either can cause erratic behavior like screen freezing. To reset the SMC, shut down your Mac, then press and hold the Shift + Control + Option keys along with the power button for 10 seconds. For NVRAM/PRAM, restart your Mac and immediately press Option + Command + P + R until you hear the startup sound twice. These resets often restore normal functionality.
If all else fails, consider reinstalling macOS or seeking professional assistance. A clean installation can eliminate deep-seated software issues, but ensure you back up your data first. Alternatively, Apple Support or an authorized service provider can diagnose hardware problems, such as a faulty trackpad or logic board, that may be causing the freezes. By methodically working through these steps, you can effectively troubleshoot and resolve screen freezing issues related to trackpad gestures on your Mac.

Updating macOS and Trackpad Drivers
Outdated software often underpins trackpad-induced freezes on Macs. macOS updates frequently include refinements for trackpad responsiveness and gesture compatibility, while driver updates ensure hardware and software communicate seamlessly. Neglecting these updates can lead to conflicts, particularly after introducing new peripherals or following a major macOS release.
Begin troubleshooting by checking for macOS updates via System Settings > General > Software Update. Apple typically releases incremental updates addressing stability issues, so installing the latest version is crucial. If the problem persists, delve into trackpad-specific driver updates. These are often bundled within macOS updates, but occasionally require manual intervention.
For external trackpads or third-party devices, visit the manufacturer’s website to download the latest drivers. Logitech, for instance, provides a software utility that automatically detects and installs updates for their devices. Ensure compatibility by cross-referencing your macOS version with the driver requirements. Incompatible drivers can exacerbate freezing issues rather than resolve them.
A lesser-known yet effective strategy involves resetting the System Management Controller (SMC) and NVRAM, which manage hardware functions like trackpad responsiveness. Shut down your Mac, then press and hold the Shift + Control + Option keys on the left side of the keyboard, followed by the power button. Release all keys, then restart. This resets the SMC, often resolving hardware-software communication glitches.
