Plus when you get leopard do not use the standard upgrade path of installing. Use the way of initially installing Leopard. Trust me it will prevent a lot of upgrade headaches. Once Leopard is running do not open any programs yet. Just open you favorite browser and down load the and update it. When it reboots download the and it will take you straight to the latest 10.5.6 version of Leopard. Be patient because there will be a big security update inside the combo that will reboot the Mac twice, this is normal.

Mac OS X 10.5.6 Combo Update is Apple's recommended update for all users running Mac OS X Leopard 10.5.0. Os x yosemite download pc. Mac OS X 10.5.0 includes general operating system fixes that enhance the stability, compatibility and security of your Mac.

Once 10.5.6 is all done then use Software Update to get the remaining updates. Lastly get the free program so it will find & point to all the program updates you applications will need to function in Leopard. Note: One word of warning is Application Enhancer hackies from Tiger broke the Leopard install. So junk all the Application Enhancer plugins before upgrading to Leopard.

Machine Name: iBook G4 Machine Model: PowerBook6,3 CPU Type: PowerPC G4 (3.3) Number Of CPUs: 1 CPU Speed: 800 MHz L2 Cache (per CPU): 256 KB Memory: 640 MB Bus Speed: 133 MHz Boot ROM Version: 4.7.7f0 Serial Number: UV35157EPGZ Hello, same as above, I wouldlike to upgrade to 10.5 at least, tho do not know if it is possible with my specifications; and please bare in mind im an artist and not so clever with computers (good excuse), shell i do all of the things in post above? Thank you very very much who ever read this!!! It is a Powerbook. According to my Mactracker, the highest OS is 10.5.8. Salsoulkid I did not think you could unless you already had 10.5. Apparently, you can but it is more expensive. If you want to save $ you may be able to get 10.5 from a dealer--RETAIL DISK--say on ebay, but if you poke around HERE you will find that often results in people buying machine-specific DVDs which become glorified coasters.

You are essentially paying ~140 for 10.5 plus the added goodies of iLife and iWork. Just scanning eBay you will find 10.5 running from ~40 to ~200. The ones advertising as 'Retail' tend to run on the higher end. I see someone is selling gray disks from a iMac! You get nowhere!

Caveat emptor. I saved $$$ when I bought retail 10.3 and 10.4 disks..

When 10.5 was already out. I was a ludite happy with OS 9 on a Wee Pismo. My current Mac came with 10.5 so the upgrade to 10.6 was cheap. Either way, you need to decide if you want to save a bit of money on 10.5 or get iWork and iLife as part of the package.
