How to Install Old Version of OS X in VM to run Flash 7 on 2020 MacBook Pro If the current instance of Mac isn’t stable enough to boot your computer, you can power it on, and use the Command + R keys as explained in this step to get to Recovery Mode. From here you can repair any errors with hard disk, add, remove, or resize the partitions, restore data from a Time Machine backup, etc. This restarts your computer in Recovery Mode. Once everything is in place, here’s how you can re-install Mac on your computer:Ĭlick the Apple logo from the top-left corner, click Restart, click Restart again in the confirmation box, press and hold down the Command + R keys as your computer powers up again, and release the keys as soon as you see the Apple logo on the screen (and before the progress bar appears). Note: Because the re-installation process may require complete erasure of your hard drive, it is important to back up your data using Time Machine or any other third-party backup tool of your choice before proceeding. This is important because the operating system (macOS High Sierra for this example) is downloaded from the Apple’s recovery server, and if there’s no Internet connection, you will be displayed with “The recovery server could not be contacted” error at the time of re-installation. Re-installation of Mac requires your computer to be connected to the Internet. You may have a couple of reasons to consider re-installing Mac, namely your currently installed instance became unstable, the system files of your Mac got corrupted and aren’t repairable anymore, Disk Utility failed to repair the hard drive errors from within the operating system, etc.
