Waiting and a little bit of background-checking may have prevented what seems to be a bad upgrade experience. I don't mean to be pedantic, but this is not Apple's problem. Those same folks often do not pre-create new drivers for new versions of Windows either (HP). Many device manufacturers have such a small customer base in Apple users that they often do not obtain beta version of OS X software for development/testing, it is just not a priority for them. Waiting, for manufacturers to catch-up and produce drivers for the new OS is always a good idea. Since a restore would require wiping the hard drive, reinstalling the former operating system, a restore of user data is the next logical step. Asking that is not a stretch of any situation. Especially, if an operating system upgrade is to be performed. One should ALWAYS make a backup of their data, to an external storage medium, on a regular basis. Apple did not make anyone upgrade their operating system, the choice is upon the user. Also, the upgrade is not mandatory, it is discretionary. One is changing the system on which the computer's hardware is used and the software programs run. Upgrading a computer's operating system is not a trivial matter. I suggest you make a separate backup using Carbon Copy Cloner 3.4.1. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard. This will erase the whole drive so be sure to backup your files if you don't have a backup already. Click on the Partition button and wait until the process has completed.Ĥ. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Otherwise, click on the Partition tab in the DU main window.ģ. SMART info will not be reported on external drives. If it does not say 'Verified' then the drive is failing or has failed and will need replacing. Note the SMART status of the drive in DU's status area. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. When the menu bar appears select Disk Utility from the Utilities menu.Ģ. After the installer loads select your language and click on the Continue button. Boot from your Snow Leopard Installer Disc.
