Though the sun is quickly setting on Mountain Lion, Apple released an update for its current operating system today. This is likely to be the last major update to Mountain Lion as Apple’s new OS is slated to be unveiled at WWDC next week. The update bears the less-than-sexy moniker 10.8.4 and fixes various bugs while adding several improvements. It’s available for download today through the Mac App Store Software Update.

The squashed bugs include issues with FaceTime calls to non-U.S. numbers and enterprise Wi-Fi connections. The update also includes improvements with Microsoft Exchange compatibility in Calendar and improvements with VoiceOver in PDF documents. Lastly, the update bumps Safari up to version 6.0.5, which, according to Apple, “improves stability for some websites with chat features and games.”

WWDC 2026: iOS 27, Siri AI, Apple Intelligence upgrades, and everything else
Apple stopped making promises at WWDC 2026 and started delivering: Siri AI, six OS updates, and Cook's farewell.

Unlike most years, Apple’s WWDC 2026 carried more weight than usual, not just because it was Tim Cook’s final keynote as CEO, but also because it represented Apple’s chance at redemption after missing deadlines, mounting questions, and criticism about its ability to keep pace in the AI race. 

Fortunately, Apple answered many of those questions on June 8, 2026, unveiling an upgraded AI-powered Siri alongside a range of new Apple Intelligence features, while also raising a few fresh questions. WWDC was packed with announcements across six operating systems that underpin Apple’s ecosystem of devices.

reMarkable Paper Pure review: An excellent digital slate that I love, and feel vexed by
If you love writing, or just want to get back in the groove, it's unbeatable. If you seek digital conveniences, too, there are better options.
reMarkable Paper Pure digital note-taker device.

Quick Review

I bought into the reMarkable dream years ago and tried multiple slates, but the Paper Pure is the version I keep coming back to. At $399, it’s the entry-level E Ink tablet from the brand that finally retires the aging reMarkable 2, and it does so by stripping away almost everything you’d expect from a 2026 gadget.
