Os X 2017 Release Date Mac Operating System

High SierraвЂ™s system requirements are the same, except that High Sierra now requires 14.3 GB of available disk space, and a minimum of OS X Mountain Lion (10.8) to do a direct-upgrade installation.Apple recently released a new version of its Mac operating system, macOS Sierra (version 10.12).With the release of Sierra, Apple decided to drop support for some Mac models that wereВ supported by several previous releases of the Mac operating system. Apple + How To + Recommended What to Do if Your Mac CanвЂ™t Run macOS SierraNote: Although this article was written for macOS Sierra (10.12), much of it still applies to macOS High Sierra (10.13) which was released in September 2017. The successor to OS X El Capitan, it is the first version of the operating system issued under the June 2016 rebranding as macOS.This part, and what follows, about moving the Installer may be relevant:Check your main Applications folder or - if you have moved an older OS X El Capitan installer.app to a different folder - this second folder for the app. I have a 'Installer' folder in my user folder dedicated to OS X Installer apps (the latest but also older OS X versions) and the single installer.apps will be downloaded (or 'updated' to the latest version) there.I had moved the original installer to Downloads so when I tried to install the new update App Store downloaded a new installer which installed the older version.I moved the original installer back to Applications and now when I go to the El Capitan page (clicking on the El Capitan link in the update window) it now gives me the option to 'open' rather than 'install'. Clicking on that opens the old installer rather than downloading a new one as it did before.I've now taken the old installer out of Applications and into the Trash, without emptying the Trash, and the phantom update has now disappeared.Out of interest I tried putting the installer back in Applications to see what happens. Aside from Sierra, for those on Mac OS X Yosemite and OS X El Capitan, Security Update 2017-003 is available for each release in the Mac App Store as well.

Apple has not previously responded to press inquiries about this subject. Keeping up with the latest macOS updates and using third-party antivirus and security software ( might we recommend some?) are important factors in keeping your Mac protected.Apple does not make any public statements concerning how long it will continue to release XProtect updates, let alone security patches, for any particular Apple software or operating system.While Microsoft publicly announces its support timetables for Windows and other software, and the Ubuntu Linux company Canonical does likewise, Apple has never given any official notice regarding how long each version of macOS or iOS will continue to receive security updates. For now, Flash and Java also officially support Mavericks and later.Browsers and plugins are commonly exploited as a means of infecting computers, so itвЂ™s critical that these programsвЂ”along with the operating systems that run themвЂ”stay up to date.The only security-related update that Apple isВ continuing to release for Snow Leopard through Mavericks is the XProtect вЂњSafe Downloads List,вЂќ which blocks a handful of malicious downloads (although signatures are often added too late to be of much use) and prevents Flash and Java content from running in your browserвЂ”if your plug-ins are too outdated and likely to be exploited.ItвЂ™s important to note that XProtect updates, while better than nothing, are by themselves insufficient to adequately protect your Mac. For example, the latest versions of Chrome and Firefox wonвЂ™t run on anything older than Mavericks. Some early Intel Macs released in 2006 are stuck with Snow Leopard (10.6), which hasnвЂ™t received security updates since the release of Mavericks three years ago.Being stuck on an old version of macOS is not something you can safely ignore.For one thing, running an old operating systemВ means you wonвЂ™t receive critical security updates from Apple.Moreover, many third parties have stopped releasing software updates compatible with older operating systems.

El Capitan requires one of the following Macs with at least 2 GB of RAM, 8 GB of available hard drive space, and at least Mac OS X Snow Leopard (version 10.6.8): El Capitan Capable MacsIf your Mac canвЂ™t run Sierra, thereвЂ™s still a decent chance that it can run the previous version of macOS, El Capitan, which may continue to receive security updates from Apple for another year or two. Taking this upgrade path will allow you to preserve your hard driveвЂ™s contents.Before you upgrade, be sure to read our How to Prepare Your Mac for macOS Sierra article for additional advice. Sierra Capable MacsMacOS Sierra requires one of the following Macs with at least 2 GB of RAM, 8.8 GB of available storage space, and at least OS X Lion:Those who are unsure which Mac model they own may find EveryMac and apple-history to be useful sites.If you have a compatible Mac with a version of OS X that predates Lion (for example, Snow Leopard), you will need to download Sierra on another compatible Mac with Lion or later, create a bootable Sierra flash drive or external hard drive (using AppleвЂ™s official instructions or the third-party tool DiskMaker X), and do a clean install overwriting the hard drive on your MacвЂ”so be sure to carefully back up all of your files first.An alternative solution for upgrading a compatible Mac from Snow Leopard to Sierra is to first upgrade to your choice of Lion through El Capitan (if you happen to have a bootable installer from one of those versions of macOS handy, or if youвЂ™re able to download one from the Purchased section of the App Store and use DiskMaker X to create a bootable installer), and then do a second upgrade from that macOS version to Sierra. If your Mac is older than the ones listed directly below, read on for suggestions about what you can do to upgrade to an operating system thatвЂ™s still getting security patches.

This didnвЂ™t just happen once it has happened again and again.Universal binary malware can run on old Macs, too. Worse, when users check the App Store for updates (or on older Macs when users run Software Update), it misleadingly tells them, вЂњNo Updates AvailableвЂќ or вЂњYour software is up to date.вЂќ This means that Mac users often have no idea that theyвЂ™re using unpatched, insecure software that could expose them to drive-by malware installations and other security problems.вЂњYour software is up to date.вЂќ вЂ¦Except it isnвЂ™t.Lest you think that nobody would bother releasing malware to attack such old systems, in recent years malware has been found in the wild that was designed to attack multiple platforms, and occasionally this malware has contained code capable of infecting old operating systems and even Macs with PowerPC G4/G5 processors (AppleвЂ™s processors of choice prior to transitioning to Intel in 2006).

(At the time of this writing, 16.04. While Apple may not support your Mac anymore, ironically, Microsoft does Windows 10 still supports systems with 1 GHz processors, 1 or 2 GB of RAM, and 20 GB of available hard drive space.Alternatively, if you canвЂ™t afford to buy a copy of Windows or just canвЂ™t stand the thought of running Windows on your Mac, or if you prefer free/libre and open-source software, there are guides online detailing how to install Ubuntu Linux on a Mac.There are even versions of Ubuntu that are still being made available for PowerPC-based Macs with a G3, G4, or G5 processor. Alternative OptionsWhat can you do ifВ Sierra is not supported on your Mac and you canвЂ™t afford to buy a new computer?If you have an older Intel Mac, you have several options.One solution is to set up Boot Camp and install Windows to use as your MacвЂ™s primary operating system. This makes non-upgraded or non-upgradeable Macs a potentially significant target (roughly 20 to 30 million computers) for criminals interested in infecting a large quantity of devices.*Anyone still using a Mac that cannot be upgraded to Sierra, or at least El Capitan, should strongly consider buying new hardware if they can afford it.
