Moreover, Apple keeps the OS X update process very simple so that every user can upgrade to a newer version without the assistance of an Apple expert. Despite all these measures, many Mac users come across data recovery problems either during the OS X upgrade processes or after the OS X installation. Data losses while an OS X upgrade isn\u2019t limited to any specific Mac devices, but it can occur on an iMac, MacBook Pro, Air, Mini or Pro.<\/p>\n\n\n\n<p>A failed OS X installation wouldn\u2019t affect a pro-active Mac user who readily backs up everything to a Time Machine drive. Even if the Mac fails to boot to an OS X, the user can still boot into <strong>Recovery<\/strong> <strong>Mode<\/strong> and choose the option \u201c<em><strong>Restore from Time Machine Backup<\/strong><\/em>\u201d which will restore the previous version of OS X with all data back to the user\u2019s Mac. It\u2019s that simple!!<\/p>\n\n\n\n<p>Let us consider an example. <strong>Mr<\/strong> <strong>Patrick<\/strong> didn\u2019t take backup of his Mac system and went forward to upgrade to <strong>macOS<\/strong> <strong>Sierra<\/strong>. During the operation, the Mac rebooted and showed Mr Patrick the error \u201c<em><strong>OS X Sierra couldn\u2019t be installed on your machine<\/strong><\/em>\u201d.<\/p>\n\n\n\n<p>In the absence of a Time Machine backup copy, rolling back to the previous OS X and restoring data becomes a dream. Every time, he restarts his Mac, the monitor greets him with the same error \u201c<strong><em>OS X Sierra couldn\u2019t be installed on your machine<\/em><\/strong>\u201d.<\/p>\n\n\n\n<p><h2><span style=\"text-decoration: underline;\"><strong>Solution (As recommended by Apple)<\/strong><\/span><\/h2><\/p>\n\n\n\n<p><strong>Step 1)<\/strong> On the event of encountering the error mentioned above, Apple recommends to backup and format the targeted hard disk drive. If you can back it up without any issues, then the problem will be solved. But,<\/p>\n\n\n\n<p><strong>Step 2)<\/strong>If the hard drive couldn\u2019t be backed up, then you must perform a small surgery to resolve this issue. Please follow below advice:<\/p>\n\n\n\n<ul><li>Restart Mac and go to Recovery Mode and select Disk Utility<\/li><li>Go to Partition tab and decrease the size of your startup disk just a little bit.
