Brock Information Technology Services now recommends caution in upgrading to OS X 10.9, Mavericks. While the current release of this operating system is stable, and will work well if you have the hardware resources to run it, we caution about upgradig to this free release of the OS without some precautionary steps.
Our recommended procedure BEFORE upgrading to Mavericks is the follwoing:
First, make sure you have a current backup of any important data on your computer. This may be in the form of a Time Machine backup (Apple's built in system to back up to external hard drives), or some other way of backing up the data to a device other than the built in hard drive. If you have questions about this, call the HelpDesk at X4357.
If your backup is current the next step is to check the hard drive for problems. The easiest way to check is using the Disk Utility program.
To run Disk Utility, open the Applications folder on your drive and then open the Utilities Folder. Find the program, "Disk Utility" and double click it to open it.
Next, choose your startup volume from the list of available drives, (most likely called "Macintosh HD") and then click “Verify Disk.” Disk Uitlity will check out your hard drive, and make sure there are no problems.
If it does find something wrong, do not proceed with the upgrade. Call the HelpDesk and arrange for someone to check your machine. If you perform a major upgrade to an operating system with a problem hard drive, loss of data is possible.
For more information on the Disk Utility program see this Apple article.
If you purchase a new Macintosh system it will come with Mavericks and ITS will support this operationg system.
