Upgrade to macOS Big Sur

Learn how to set up and use macOS. Find all the topics, resources, and contact options you need for macOS. I have a MBP 2011, with high sierra now. I remember not being able to use the web recovery mode so i had to re-install lion using an external bootable usb with lion on it and upgrading via the app store all the way up to yosemite and sierra. I am no expert but you could do the same with mavericks in your ssd and upgrade from there. If you want to upgrade to this version, it is possible as long as your current operating system version is lower than macOS High Sierra. Natively, look for “Disk Utility” in your application, select an external USB device with a capacity of 8 GB or larger, format it directly, and remember to choose the format “Mac OS Extended (Journaled)”.

Before installing this upgrade, make sure that your Mac is ready.

• Safari automatically keeps an eye out for any saved passwords that may have been involved in a data breach. Using advanced cryptographic techniques, Safari periodically checks a derivation of your passwords against an updated list of compromised credentials. If a breach is discovered, Safari helps you upgrade your existing passwords.
