Installing OSX Leopard 10.5

You will have to look online and order the DVD Leopard 10.5.x Retail version. As

these are not grey-label. Those were for 'mac-specific' for intel-mac; not PPC G4/G5.

(Snow Leopard 10.6.3+ will not work in PowerPC/PowerMac systems.)

Examples of online sources (ebay, amazon, private owner, online reseller) can be

found in such searches. ~ While before they were scarce, I bought mine locally at

yard sales, or in craiglist ads; had fairly good luck, too.

The 867MHz CPU processor on margin where you cannot upgrade past Tiger 10.4.11.

You'd need to have higher speed processor than this to use Leopard 10.5(.8). Either

way, for web browser you'd need TenFourFox; in Tiger or Leopard. That's about it now.

For email client, there's a 'Tenfourbird' Project with software that should work OK.

Good luck & happy trails!🌻🌤

There had been companion upgrade discs sold separately from Mac OS X

for the step up from Tiger 10.4.11. An official Apple kit for Leopard 10.5.x &

one of them in retail packet included iLife. ~ Altogether, the 'package' deal

had three? DVDs. So with those, the retail Leopard 10.5.x could upgrade to

be similar to the newer "as-shipped" Mac's installed systems.

Two later versions of iTunes, one for Tiger + other for Leopard, should be here:

• iTunes for Tiger 10.4.11 & Leopard 10.5.8 - Apple Community/User Tip

https://discussions.apple.com/docs/DOC-13011

Somewhere, I've DVDs to upgrade Leopard beyond the retail DVD; add iLife,

& maybe iWork titles? These generally were included in new Leopard w/ Mac.

• Mac Box Set (old Version) iLife, Leopard, iWork:

{Mine, bought separately; I know there'd been 'official combination' package.}

Good luck & happy computing!🌞☘

I found this thread because my 2005 powerpc ibook recently started running into problems getting mail over ssl (and browsing certain pages in web browsers). I'm guessing this is because the older ssls have been deprecated out of existence.

Just wondering if something similar motivated the OP? And if Leopard would fix that?

My ibook has a 1.42 ghz PPC chip - would that be enough for Leopard?

Yes it's enough for Leopard, but 10.5.8 isn't much of an upgrade from 10.4.11, in fact I think it was mostly a downgrade.

As far as Mail & Internet, you might be stuck with WebMail & using TenFourFox Parity release...

re: mmodrall :

There had been a custom build PPC version of Thunderbird email client

however I've not used it; & doesn't appear up-to-date. ~ It held promise:

• Tenfourbird (4 years ago/latest comments 2 years ago)

I've not looked for newer PPC-specific email client, your mileage may vary.

TenFourFox with browser 'login to Gmail' works still; just much slower now.

(And 10.4Fox still works with ASC here; but does not allow corrections.

My iBook G4 1.33GHz late model 12-inch portable found Leopard 10.5.8 as

resource demanding; even w/ RAM upgrade to 1.5GB. (Likes Tiger better!)

While my Late 2005 Mac mini G4 does OK w/ TenFourFox in Leopard 10.5.8.

[..TenFourFox_G3 version 'does OK' with MacBook1.1 in Leopard; w/7200-RPM

hard drive and 2GB RAM..]

Good luck & happy computing!🌻🌤
