Click Update to download and install all the available updates. If you want to learn about the details of each update before installing, click the arrow next to the Update button and review the apps, versions and installation date. Then click Update All or Update next to individual apps. Update Office from the Mac App Store. Download Apple Mac OS X Lion 10.7.5 Supplemental Update for Mac to update your Mac OS X Lion for Intel-based Macs.
OS X 10.7 Lion was released on July 20, 2011 and made some huge changes to the Mac. Some of these changes were to make it easier for iPhone, iPad, and iPod touch users to adapt to the Mac, some to make the two platforms work better together, and some to keep making the Mac better and better.
Lion was only available by purchase and download from the Mac App Store, where it retailed for US$29.99. You must have OS X 10.6 Snow Leopard installed to purchase, download, or install Lion, and the 4 GB download could take some time with slower DSL connections (we don’t even want to think about how long it would take with dial-up). As a convenience, Apple allowed users to bring their Macs to a nearby Apple Store and use Apple’s WiFi to make the download.
Like OS X 10.6 Snow Leopard, Lion requires an Intel-based Mac, but it goes two steps beyond that. First of all, Lion is a 64-bit operating system, so it won’t work on those 2006 Macs built around 32-bit Core Solo and Core Duo processors. It requires Core 2 Duo or newer, which leaves the following Macs behind unless you update the firmware and install a Core 2 Duo CPU:
Additionally, Lion is the first version of OS X with no support for PowerPC software. Apple introduced Rosetta, which lets Intel CPUs run PowerPC apps, with OS X 10.4 Tiger for the first Intel Macs in 2006, and it had been part of OS X until now.
The last version of Lion, OS X 10.7.5, was released on October 4, 2012. It was the first version of Mac OS X to be part of the annual upgrade program – ever since Lion, Apple has released a new macOS version every year.
Lion was replaced by OS X 10.8 Mountain Lion on July 25, 2012, just a year after Lion first became available. Lion is no longer available for purchase through normal App Store channels, although you may be able to acquire access to it through Apple Support.
Lion is the oldest version of OS X impacted by the “goto fail” bug. See Apple and the ‘goto fail’ Bug for information on securing Lion.
You can’t just install Lion on any old Mac that support it. The installer’s certificate has expired, so you need to set your Mac to think it’s operating in the past. Using trial and error, I found that setting a date in 2012 will let the installer function. To change your Mac’s date:
After you complete the process, be sure to set your Mac to the current date and time. Enabling the Set date and time automatically setting is the easiest way to do it.
Standalone updates let you update to a newer version of Mac OS X from your hard drive instead of using Software Update, which requires an Internet connection. This can be especially helpful if you have more than one Mac that need to have the update installed, since you only have to download it once. Download the one(s) you need and install them after mounting the disk image and launching the Installer program.
There are two types of Standalone Updates: Individual (or Delta) and Combo.
Standalone Updates are generally available 24 to 48 hours after the Update is available through Software Update.
If you burn a Standalone Update to CD, its disk image must be copied to your desktop or another location on your Mac OS X startup disk in order to be installed.

Updating a Mac to OS X 10.11.4
Apple’s macOS 10.13 High Sierra launched two years ago now, and is obviously not the current Mac operating system – that honor goes to macOS 10.14 Mojave.

2 Answers. It is safe to delete, you will just be unable to install macOS Sierra until you re-download the installer from the Mac AppStore. Nothing at all except you would have to download it again if you ever need it. After install, the file would usually be deleted anyway, unless you move it to another location.
The first, and most important thing you should do before upgrading to macOS Mojave (or updating any software, no matter how small), is to back up your Mac. Next, it is not a bad idea to think about partitioning your Mac so you can install macOS Mojave in tandem with your current Mac operating system.
How to update macOS in Mojave

How to Install MacOS Mojave 10.14.4 Update
If a version of macOS isn’t receiving new updates, it isn’t supported anymore. This release is supported with security updates, and the previous releases—macOS 10.12 Sierra and OS X 10.11 El Capitan—were also supported. When Apple releases macOS 10.14, OS X 10.11 El Capitan will very likely no longer be supported.
Method 1 Check your Computer’s Specifications
Most Mac models introduced in 2012 or later are compatible with macOS Mojave, and you can upgrade directly from OS X Mountain Lion or later.
Launch the App Store on your Mac (click on the blue icon containing a white A, or search by pressing space+command and typing App Store). Search for macOS (or you can also go directly to the macOS High Sierra page if you click here). Click on macOS Mojave (or the version of Mac OS X you require). Click on Download.
Apple’s next Mac operating system, MacOS High Sierra, is here. As with past OS X and MacOS releases, MacOS High Sierra is a free update and available via the Mac App Store.

Downloading Mac OS X from Mac App Store
The first thing to do is check to see if your Mac can run macOS High Sierra. This year’s version of the operating system offers compatibility with all Macs that can run macOS Sierra. Mac mini (Mid 2010 or newer) iMac (Late 2009 or newer)
Apple’s macOS High Sierra update is free to all users and there is no expiration on the free upgrade, so you don’t need to be in a rush to install it. Most apps and services will work on macOS Sierra for at least another year. While some are already updated for macOS High Sierra, others are still not quite ready.
