2009 ibook

The computer would probably be a MacBook 13-inch model, if it looks like an iBook but was made

or bought new in 2009; the iBook G4 was no longer manufactured after the Mid-2005 build series.

The Mavericks 10.9 OS X version is no longer available. Depending on the actual build year spec

information, the level of OS X upgrade (or perhaps best suited OS X for the vintage build) can be

found and the possibilities discussed. The last OS X available on DVD install media, is OS X 10.6;

that would be Snow Leopard and a retail version of that (unless the computer shipped new with a

version of Snow Leopard 10.6.x in disc media specific to that model; then you'd use it to wipe the

computer and start over with a completely new OS X installation.)

An original iBook G4/G3 PowerPC computer cannot be upgraded to run an OS X past 10.4.11 or 10.5.8.

Intel-based Macs can run OS X versions past Leopard 10.5.8; Snow Leopard 10.6.8 is required in an

Intel-Mac before it could be upgraded to any system past 10.6.8, such as 10.7.5. 10.8.5, or 10.10.x

•Mac OS X 10.6.8 Update Combo v1.1 - for use after installation of Snow Leopard from DVD

If the computer does not have at least OS X 10.6.8 available to it, via an installer DVD, this is

the main source for official Snow Leopard 10.6.3; the combo update to 10.6.8 applies to this

once it is installed, and that would be a download once the base 10.6 system is running in it.

The computer may also require an upgrade in the amount of installed RAM memory so that later

OS X versions can perform better. Usually above the minimum requirements is recommended so

the computer OS X and applications running in it, can have a chance.

Older computers that have never had their internal hard disk drive replaced, may be candidates

for this since they do wear out and when the fail, will cause a loss of data and user information

along with anything saved in the hard drive. A backup plan to store important items in duplicate

to an externally enclosed hard drive, is recommended, too. At least one external archive.

So to identify the computer correctly and exactly is a beginning.

Good luck & happy computing! 🙂
