Earlier this year, Apple announced that it was leading the charge on a cross-industry effort to bring end-to-end encryption (E2EE) to the RCS Universal Profile, which is published by the GSMA. Apple told 9to5Mac in March it would come to the iPhone in a future software update. Google soon after jumped in, stating it too was ‘committed to providing a secure messaging experience.’

I didn’t think it was completely unreasonable to assume we’d see this showcased at WWDC 2025…that didn’t happen. Then I thought maybe in one of the iOS 26 betas? Also nothing. So, what happened to cross-platform E2EE for RCS messaging? Is it still coming?

Do you need third-party anti-virus software on a Mac?

Do you need third-party anti-virus software on a Mac? | Close-up of older MacBook with illuminated Apple logo

For many years, it was accepted wisdom that Mac malware wasn’t really an issue. One of the reasons for that was that the market share was simply too low to make it a worthwhile target for attackers.

Today, of course, is a very different world. Macs are the fourth most popular brand of personal computers, and as owners of a premium brand, Mac owners make a juicy target. Does that mean you need third-party antivirus software on a Mac, or are the built-in security protections good enough? A very thorough test sought to find out …

If you upgraded to iOS 26, you know the design changes and visual overhaul of Liquid Glass are undeniably impressive. But from a security perspective, one feature in particular has piqued my interest and seemingly gone under the radar: a new permission setting for wired accessories.
