Despite Apple's confidence in the fact that Mac OS X updates are for all users "without a hitch, without a hitch," I have more and more often hear of the owners of the mouth apple machinery phrase, uttered in a custom Linux users: "There was sadness - updates pumped ..." So I want to tell you today readers about how to properly prepare for the renewal of the operating system, not to obrosti gray earlier in case of emergencies time.
Make a backup
Always back up your system before you upgrade. The best way to do a full backup, which is then easily restore - is to use Time Machine, but also suitable and easy cloning system using SuperDuper, Carbon Copy Cloner or another programs.
Do not forget to check the backup to make sure in the successful restoration of the first necessity. After this, unmount the disk for backups or even turn it off (or Time Capsule), that in the process of updating the system is not affected by a backup copy, if that could be enough.
Eliminate the current problems
If you regularly have great difficulties in working with the existing version of Mac OS X, try to solve them in the first place. Although the operating system update can rezhit software errors from serious problems with stability system or hardware (eg, random crashes, reboots, strange noises) set of commands in machine language you do not save.
Perform a "spring cleaning"
Try to hold on Saturday a computer. Not shovels and rakes, of course, but with the help of specialized tools such OnyX, Snow Leopard Cache Cleaner, IceClean, Yasu, Cocktail or any other. If you do this too lazy, at least boot your system in Safe Mode (at the same time to perform some scripts for the prevention system) and use Disk Utility (Disk Utility) to "restore rights access. "
Disconnect peripherals
If you have an external USB- or Firewire-devices, disconnect them from the system before upgrading, as they might interfere with installation. they can also cause problems during the first boot after the update installation, as the system re-configures the device and boot cache. Do not worry, in the future you will be able to connect them back.
In theory, by following these steps you will be one step closer to a successful upgrade.
