Geek Posted February 3, 2012 Posted February 3, 2012 <div class="KonaBody"><p><img src="http://osxdaily.com/wp-content/uploads/2012/02/recovery-hd.jpg" alt="Recovery HD" title="recovery-hd" width="182" height="232" class="alignright size-full wp-image-26777" /> All Macs with OS X Lion have a bootable Recovery partition that can be accessed in case of system problems, allowing you to troubleshoot, restore from Time Machine backups, and even reinstall Mac OS X.</p> <p><strong>Hold down Command+R keys during boot</strong> to access the Recovery HD partition.</p> <p>You’ll know you’re in recovery mode because the standard desktop won’t be displayed, replaced with a limited Mac OS X Utilities window and a simple Mac OS X menu bar. Here you can use Disk Utility, Time Machine, and restore the OS.</p> <p>From the Utilities menu you can access Network Utility, use the Firmware Password Utility, and launch the Terminal, which lets you <a href="http://osxdaily.com/2011/11/15/repair-user-permissions-in-mac-os-x-lion/">repair user home permissions</a>, <a href="http://osxdaily.com/2011/08/22/launch-and-use-any-mac-os-x-app-when-booted-from-os-x-lion-recovery-hd-drive/">launch other apps</a>, and perform other diagnostic tests.</p> <p><img alt="Launch Terminal from the Utilities menu" src="http://osxdaily.com/wp-content/uploads/2011/08/launch-terminal-from-recovery-hd.jpg" title="Launch Terminal from the Utilities menu" class="aligncenter" width="615" height="228" /></p> <p>To reinstall Mac OS X Lion from the Recovery partition, you will need an active internet connection, although this isn’t necessary if you booted with a <a href="http://osxdaily.com/2011/07/08/make-a-bootable-mac-os-x-10-7-lion-installer-from-a-usb-flash-drive/">full Lion USB installer</a> rather than the built-in Recovery HD partition or a disk made with the <a href="http://osxdaily.com/2011/08/08/lion-recovery-disk-assistant-tool-makes-external-lion-boot-recovery-drives/">Lion Recovery Assistant tool</a>.</p> <p>Note that if you <a href="http://osxdaily.com/2011/06/30/deleting-the-mac-os-x-10-7-lion-recovery-hd-partition/">deleted</a> the Recovery HD partition, you can not access these features.</p> <p><em>Thanks for the tip idea @oldrobots</em></p> </div> <p><a href="http://feedads.g.doubleclick.net/~a/raf5_NyLIDrXe9EV50fNRXJzEbk/0/da"><img src="http://feedads.g.doubleclick.net/~a/raf5_NyLIDrXe9EV50fNRXJzEbk/0/di" border="0" ismap="true"></img></a><br/> <a href="http://feedads.g.doubleclick.net/~a/raf5_NyLIDrXe9EV50fNRXJzEbk/1/da"><img src="http://feedads.g.doubleclick.net/~a/raf5_NyLIDrXe9EV50fNRXJzEbk/1/di" border="0" ismap="true"></img></a></p><div class="feedflare"> <a href="http://feeds.feedburner.com/~ff/osxdaily?a=0qUxOCW-VqM:yGsI13UAuaw:yIl2AUoC8zA"><img src="http://feeds.feedburner.com/~ff/osxdaily?d=yIl2AUoC8zA" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/osxdaily?a=0qUxOCW-VqM:yGsI13UAuaw:V_sGLiPBpWU"><img src="http://feeds.feedburner.com/~ff/osxdaily?i=0qUxOCW-VqM:yGsI13UAuaw:V_sGLiPBpWU" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/osxdaily?a=0qUxOCW-VqM:yGsI13UAuaw:D7DqB2pKExk"><img src="http://feeds.feedburner.com/~ff/osxdaily?i=0qUxOCW-VqM:yGsI13UAuaw:D7DqB2pKExk" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/osxdaily?a=0qUxOCW-VqM:yGsI13UAuaw:7Q72WNTAKBA"><img src="http://feeds.feedburner.com/~ff/osxdaily?d=7Q72WNTAKBA" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/osxdaily?a=0qUxOCW-VqM:yGsI13UAuaw:qj6IDK7rITs"><img src="http://feeds.feedburner.com/~ff/osxdaily?d=qj6IDK7rITs" border="0"></img></a> </div><img src="http://feeds.feedburner.com/~r/osxdaily/~4/0qUxOCW-VqM" height="1" width="1"/> View the full article
