Apple took the curtain off Yosemite, the latest update to its Mac operating system, in Apple’s most recent Worldwide Developers Conference.

Since Mavericks, the previous OS X update, Apple has been following a new naming scheme where it will now name OS X updates after places in California. Yosemite is named after Yosemite National Park.

If you're using OS X El Capitan v10.11.5 or later and your App Store preferences or Software Update preferences are set to download new updates when available, macOS Big Sur will download conveniently in the background, making it even easier to upgrade. A notification will inform you when macOS Big Sur is ready to be installed. Click Install to. The App Store only shows updates for the OS you are using at the moment, in your case Yosemite 10.10.5. If you want to go to another newer OS that is called an upgrade. This can be done through the App Store using the following link. How to upgrade to macOS High Sierra - Apple Support.

This is particularly important if you upgraded to Yosemite over an existing OS X system. It won’t hurt with a clean install, either, after installing third-party software or updating the iLife/iWork apps to their OS X 10.10 versions. The Finder that provides access to files, folders and drives and organises them, seems to be behaving oddly after the OS X Yosemite 10.10.3 update, which Apple released earlier this week.

Yosemite is supposed to narrow the margin between the OS X, Apple’s desktop operating system, and the iOS, which is the operating system used on iPhone and iPad by introducing a more seamless experience between the two systems. You can now receive iPhone calls directly on your Mac, and view your open web pages and documents on both devices. Apple also announced the Handoff feature, where you can start writing a report on your Mac and continue it on your iPad as long as both devices are near each other.

The Handoff feature

Using Yosemite, the user interface has been revamped with a flatter design similar to that of the iOS. Translucency appears with a great degree in the design, tool bars in different applications have been streamlined to improve user experience, and Helvetica Neue is the new default system font, replacing Lucida Grande.

The notification centre was also updated to give a summary of the day’s upcoming events. It allows quick access to important information with widgets like calendar, weather and stocks.

Spotlight search now appears front and center when you open it and can be used to look up information from multiple sources like Wikipedia, maps, movies, and more. Search results are now more interactive so you can read a document, send an email, or make a phone call by clicking a search result.

Apple announced that Mac OS X Yosemite will be available this fall, and will run on all the Macintosh products compatible with Mavericks.

Alongside iOS 8.1.1, which includes a fair dose of tweaks and fixes, this week Apple rolled out OS X 10.10.1, the first maintenance update for Yosemite users worldwide.

Generally speaking, 10.10.1 “improves the stability, compatibility, and security of your Mac.” But that’s just scratching the surface. According to a support document published by Apple hours after releasing the update, 10.10.1 actually includes a lot of specific tweaks and improvements. Here’s what to expect.

Support document HT204017 reveals that Yosemite doesn’t just fix Wi-Fi connections, Microsoft Exchange integration, and Back to My Mac. It also “resolves an issue that may prevent Mail from sending messages through certain email service providers,” and it makes sharing services, Notification Center widgets and Actions available again (in certain situations).

As for an issue we’ve documented on several occasions, Notification Center settings should now be retained after reboot, and any issue that might prevent the Mac App Store from displaying certain updates should be gone now.

Update After Os X Yosemite

Some Mac mini computers would fail to wake from sleep. 10.10.1 addresses this problem, as well as an issue that might prevent Time Machine from displaying older backups. Entering text in Japanese should also be fixed.

For Enterprise users

OS X 10.10.1 includes some improvements for Enterprise customers, with Apple noting that Yosemite now “Allows you to append search domains for partially qualified domain names when performing DNS lookups (consult the discoveryd man page for more information).”

Also for Enterprise users, a problem where the Mac App Store might offer an update to Apple Remote Desktop when the latest version is already installed should no longer occur.

The Security content of OS X 10.10.1

An advisory accompanying Yosemite’s first maintenance update indicates that as many as four vulnerabilities have been discovered since the release of the software in September.

For example, Apple reveals that “Unnecessary information is included as part of the initial connection between Spotlight or Safari and the Spotlight Suggestions servers.”

Describing the flaw at large, the company explains that “The initial connection made by Spotlight or Safari to the Spotlight Suggestions servers included a user's approximate location before a user entered a query. This issue was addressed by removing this information from the initial connection and only sending the user's approximate location as part of queries.”

Other flaws affected areas like CFNetwork, System Profiler (About This Mac), and WebKit.
