All Safari pages completely black
On a 2023 MBP running Sonoma. I started experiencing an issue where every single webpage that loads in Safari is completely black. I know the page loads, I can hear videos that play, and when I cover, I see various link info in the bottom status bar, but visually everything is black. Other browsers run just fine. This page doesn't help at all: If Safari doesn't open a page or work as expected on your Mac - Apple Support
Not sure if relevant, but the day this started happening, before it actually happened, I was getting constant notifications that Safari would close every 10 minutes to run an update, and the cycle would continue. I then upgraded to Sonoma, and this black Safari issue has been constant.
Any suggestions? Thanks!
