When you boot in Safe Mode, your Mac will check its startup volume, only load necessary kernel extensions, and disable third-party fonts and startup options. Macs offer a Safe Mode, also known as Safe Boot. Select your language and your Mac will automatically test its hardware and inform you if anything is wrong. To access this tool, press and hold the D key while booting your Mac. On Macs released before June 2013, Apple Hardware Test (AHT) will appear instead of Apple Diagnostics. Test Your Hardware with Apple DiagnosticsĪpple Diagnostics tests your Mac’s hardware to ensure it’s working properly. To boot directly from the network with Netbook, press and hold N instead.
To skip the Startup Manager and boot straight from a removable device-for example, a CD, DVD, or USB drive-instead of its internal drive, press and hold C.
