Since installing Ventura (now at 13.0.1), my iMac frequently hangs. At first I thought maybe i had too many Safari tabs and windows open, and reduced the number drastically. Then, I found that this occurred even when I wasn't running Safari. I next realized that this behavior started only after upgrading to Ventura. Has anyone else experienced this behavior? This is an iMac with 128gig This is on an iMac 27" still under AppleCare.
My first thought—Uninstall all third party apps that are Cleaners/Optimizers/Anti-Virus/VPN
all known to cause issues on the macOS, no matter if they seemed to work in your last macOS without issue.
To trouble shoot further you can:
—Test issue in another user (or guest user) account Change Users & Groups settings on Mac - Apple Support
This will tell you if it a universal issue or isolated to your user/admin account.
—SafeBoot How to use safe mode on your Mac - Apple Support will sort many anomalies
This test will tell you if third party interference; extensions etc are not loaded in safe boot mode.
