Apple is continuing work on the sixth update for system generation 26 and is now releasing the third beta. This means that another two weeks have passed, which means that iOS and macOS 26.6 are not yet in the immediate final stages. Due to WWDC, Apple allowed three weeks to pass between the first and second beta. However, 26.6 is no longer a far-reaching update, because at such a late point in the annual cycle the development department is only concerned with fine-tuning. So far only minor changes have been noticed for what may be the last 26 update. The general release should take place towards the end of July or in August at the latest. 26.6 is most likely the last or second to last .x update for macOS Tahoe and iOS 26. Bug fixes and minor adjustments
Only two adjustments have been known so far. There is a warning if users have blocked more than 20,000 numbers/contacts. This can happen when apps create block lists against spam numbers – such databases often contain well over 10,000 entries. As already mentioned in the last message: It’s not the limit that’s new, just the error message. Apple also implemented a new security process for Apple Maps that screens incoming requests before processing them. This probably serves to provide better protection against injected character strings, which can cause unwanted problems.
The current betas
Finally, as always, the well-known list of currently available beta versions. The new round began with “e” or “f” in the last position of the build number; in Beta 2 it was “c” and “d”. Everyone is now familiar with Apple’s approach of counting down until you get to “a” and the release candidates without any letters at all – although sometimes it goes in the other direction. Beta 3 of macOS is now back to “e”. This is what it currently looks like in the developer area – the public beta should follow, as usual, with a short delay.
