MacOS Catalina 10.15.7 Supplemental Update 2. MacOS Catalina 10.15.7 supplemental update addresses an issue that may prevent the battery from charging in some 2016 and 2017 MacBook Pro models. Update Mac OS 8.5 or 8.5.1 to OS 8.6 for improved system performance. Apple Mac OS Update 8.6.
Need a copy of System 6.0.8, 7.0.1, or a newer version of the Classic Mac OS for your vintage Mac? You can dig through apple.com and try to find them – or you can download them using the updated links on this page. (Apple does rearrange things, making it more difficult to find things.) All versions of the Mac OS linked here are copyrighted by Apple Computer and free to Macintosh owners. System 7.1.x as well as 7.6.x and later are not free products and must be purchased.
Making Floppies
Software is stuffed and requires an expander, such as StuffIt Expander (which was traditionally bundled with early Mac web browsers). Mounting disk images or making floppies from them requires Disk Copy (download Disk Copy) or MountImage.
You will need a 400K or 800K floppy drive to produce single-sided disks for use with the Mac 128K and 512K Fat Mac. Apple’s high density floppy drives cannot format single-sided floppies.
You cannot use a USB floppy drive to create 800K floppy disks; they can only be formatted and written to using an Apple 800K or 1.4M HD floppy drive.
You should have no trouble formatting and writing to high density floppies using a USB floppy drive.
Drive Prep
Whenever possible, Apple branded hard drives should be formatted or updated with HD SC Setup 7.3.5 or later before installing a new version of the OS. (Exception: If the hard drive of a Mac Portable is formatted with any version newer than 7.3.1, it will crash instead of waking from sleep mode.)

The latest macOS version is macOS Big Sur. It was released in November 2020 and s available for everyone to download. Here’s everything you need to know about the latest Mac operating system.
Will my Mac run macOS Big Sur?
Os X Free Upgrade
According to Apple, the oldest Macs to support macOS Big Sur will be the ones from 2013. macOS Big Sur is perfectly fit for MacBook 2015 and newer, MacBook Air 2013 and newer, Mac mini and iMacs from 2014 and newer, and also Mac Pros 2013 running macOS Mojave or later version.
Storage Space: 12 GB of free space
Memory: 2-4 GB RAM
Time: 30-50 minutes installation time
Space issue is the most crucial, though. The 12 GB of storage is a formal requirement but in reality, you’ll need twice as much to prepare the backup. No worries, if you scan your Mac with CleanMyMac X, you can free up tens of gigabytes of space by removing junk files and uninstalling applications. Download CleanMyMac X for free and get your Mac cleaned and ready for macOS Big Sur.
How to check your macOS version

- Check the version in the Overview tab.
How to update your Mac to the latest version
You can download the latest version of the macOS from the App Store. The process is not difficult but requires some preparation. Here's a comprehensive guide on how to upgrade to macOS Big Sur.
We've prepared the quick tour about the new Apple macOS — check it out.
What are the new features in macOS Big Sur?
Safari reborn
Apple’s Craig Federighi dubbed the current update “The biggest update in the history of Safari.” It’s been shown to outperform Chrome in various tests — another reason for Mac users to feel proud. Now you can customize Safari like never before, set the start page theme, control videos from the menu bar, etc. And, to the dismay of marketers, Safari gives you an option to switch off all your tracking cookies.
Fancier icons
Mac Os Upgrade Free
The Dock panel got a full on facelift featuring smaller icons, round edges, more in tune with iOS look. For the last few years Apple has been merging both systems together, and now the gap between the mobile and Mac seems to be almost unnoticeable.
Control Centre
Control Centre is the new quick-access pane that shines in Big Sur’s upper right corner. From there you can adjust volume, screen brightness, and finally, access Bluetooth in one click. Control Centre has handy toggles and keeps all the important controls in one place making it an instant like.
64-bit applications
Apple Catalina Upgrade
If you skipped macOS Catalina and, are still running macOS Mojave, there is an issue about 32-bit apps you should know about. Before Catalina the 32-bit / 64-bit app distinction was known only to programmers. These numbers represent different types of app architecture. Starting macOS Catalina and continued on Big Sur, 32-bit apps will no longer be supported on Macs. For many users this will be the single reason to avoid it and stay with good ol’ Mojave. Some big name applications, are still yet to be optimized for Big Sur and 64-bit.
If you’re still planning to upgrade, there are tools to make the transition less painful. For example, the Mac problem-fixing tool, CleanMyMac X, has an Updater feature. It checks how many 32-bits you have and updates them to newer versions (if such are available).
