Recover Data after Mac OS X Upgradation

Information technology is evolving at a faster pace and so the user’s expectations. Like whenever Apple releases an enhanced version of Mac operating system, people are keen to get it as fast as possible and to upgrade their Mac machines. With the intention to get more improved characteristics and better performance.

Upgrading your Mac to an improved OS version is not as smooth as it sounds. Because there can be many things which may go wrong and create difficulties for your Macintosh and the data stored in it. If any kind of error occurs in-between the upgradation process, then you may end up losing some or all of your critical data.

Problems that may arise during or after the upgrade process

  • Ignored the Backup Option – Immediately after inserting the DVD of the new version of Mac OS X, it will ask you to take backup for your personal files to an external hard disk by using the Time Machine application. In case, you ignore this option and skip the backup action, it will erase the entire hard drive space and start installing the new Mac OS X
  • “Install Failed” Error – If your installation fails in the middle of the upgrade process and shows error message, then this may leave you with neither the old OS nor the new one. This will cause inaccessibility to your Mac volumes, hence lead to data loss
  • Error Due to Fragmented Disk – It is recommended to defragment your hard disk before OS upgradation. Since installation of the upgraded OS version will write many files to the hard disk space. Therefore it is better to have a defragmented hard drive, as this may affect your files and can cause corruption or permanent deletion
  • Denied Access to Files – Sometimes after upgradation of your Mac OS X to a newer version, you may not be able to access some of your files and folders showing error message as “Access Denied”
