Any Mac that can run Mavericks can run Yosemite, so it may be that Apple would prefer users to move to Yosemite.

It appears to me that this initial download is no longer available while 10.9.1 and 10.9.2 and 10.9.3 and 10.9.4 are readilly available and I have downloaded all of these.

10.9.0 Mac Pro 1

I need the 10.9.0 in order to convert my mac pro 1.1 tower to do what it was designed to do.

10.9.0 Install Your Original

If thats the case, doing an internet recovery will install your original 10.9.0 version of OS X.

Info here.

I assume you specifically want 10.9.0 because thats the OS that was originally installed in your Mac Pro.

The need for the 10.9.0 version has probably to do with the installing of an unsupported OS or the other way around.

Can you please help me if you can, would be very thankful.

I have the mac pro 1.1 running in 64 bit.

He asked me to pass on the favor so ask me and I will try to pass it on.

As noted in previous post only 10.9.5 is available and is strictly an update.

The only place I found it was a paying site that did not look legit.

The Apple website seems to have removed all traces of Mavericks.

I have a Macbook Air running Snow Leopard and would like to upgrade to Mavericks.

I had to wipe my macbook pro due to something that my wife downloaded and now Im trying to reinstall the updates and it says I need 10.9.

Yep. no legit way to get Mavericks any longer if you dont already have it.

You can purchase Snow Leopard, Lion and Mountain Lion from Apple so I expect that theres an Apple-provided way of getting Mavericks.

Do you know what that might be, because members have reported here they called Apple and were told it was not available.
