Has anybody tried this? I only updated my system to 10.5.3 this week, but it appears an update is already available: Mac OS X 10.5.4 Delta Update - 4 June 2008. I think it's a pre-release build, so I won't jump on it yet, all the more so since I don't have a testing partition available... The update can be found at the usual places together with a Safari 4 developer preview version which I installed and seems to be working fine ;).

WHAT?! Looks like a fake. Can someone confirm this? Well, I have an ADC account, and I don't see anything official yet in my zone. =p

I agree it could be a fake, haven't tried to download and look inside the package yet. However, the same uploader put up a developer preview version of Safari 4, which I downloaded and installed, and that is what he says it was, so he may be on to something...

Ok, I downloaded it and looked inside it with Pacifist. It appears to be a genuine update from 10.5.3 to 10.5.4, but I believe it's still in beta stages at this point, I'd try it if I had a spare Leopard installation, but I don't, so I'll let it rest for now.

Lin'q? Did you find it in ADC?

No, not in ADC, it can be found in the bay.

Isn't the next update going to be Snow Leopard, which is 10.6? I too believe that this is a fake.

The 10.5.4 update or 10.6 ? But if they go on with the updates so fast, they'll be at 10.6 very soon, or we have version numbers like 10.5.11 like in Tiger :-P

Hi, Naquaada,
I meant that 10.5.4 might be a fake because Snow Leopard 10.6 is already confirmed :-)

However, it's scheduled to ship in about a year - so we could see 10.5.4 before.

Go Snow Leopard! =O
