Shift Option Command R - Install the macOS that came with your Mac, or the version closest to it that is still available. Option Command R - Upgrade to the latest macOS that is compatible with your Mac Nonetheless, according to HT204904 there are actually several key combinations for Recovery:Ĭommand R - Install the latest macOS that was installed on your Mac, without upgrading to a later version. Remember that you should be able to use option key at boot which invokes Startup Manager which lets you select the available boot volumes, including the Recovery partition (without downloading from the Internet). Mac will also do that if there is a version mismatch from Recovery and macOS version installed. However, if there is no recovery partition on the disk it will automatically revert to Internet Recovery which means downloading the boot image from Apple servers. To start your Mac in Recovery Mode, first, if your Mac is turned off, switch it on. For both recovery modes, you will need enough power to see you through the process as well as your Apple ID to reinstall macOS.
The Recovery Partition on the system disk corresponds to the version of the macOS installed and should be loaded when holding Cmd R at boot (not Cmd S). Hopefully, you’ll never have to use either the normal or internet Recovery Mode for your Mac, but if you do it’s simple to access.
