10.10.2 Combo update "can't be installed on this disk"

10.10.0 is 10.10.

Good to know the non-combo update works. It's still downloading for me. I guess the servers are being bombarded for it.

Thanks.

Just confirming that the 10.10.2 Update successfully updated 10.10.1 for me. The 10.10.2 Combo Update did not work. Let's see if the Combo Updates going forward will only address the primary release (10.10.0, 10.11.0. 10.12.0).

Cheers all!

Hi.

I downloaded the 10.10.2 Combo and attempted to install on 3 machines all with 10.10.1. I get the same message. Other replies to this query seem to indicate that the 10.10.2 Combo will only install on machines running 10.10. Over many years I have never had a problem similar to this, in other words previous iterations of Combos would always install on machines regards of what stage the OS updates were at. Will wait a few days and see if Apple rectifies the issue. Or maybe this is the new "model" Apple has adopted?

Same thing here: Combo update would not update my 10.10.1 drives.

Hi,

I tried updating my iMac with 10.10.2 Combo standalone installer without success but I downloaded the Combo hosted on Software Update Server and... Bingo! Update succesfull!

What is the URL for the update server you used?

Have any brave soles tried using Pacifist to install the Combo Update?

Seeing exactly the same thing on my 10.10.1 machine. Apparently you can only use the combo on 10.10.0, not 10.10.1 (go figure). Another mess from Apple...

1. I've been using OS X since 10.4 (Tiger), and this is the FIRST time the "combo" updates would not work on dot releases.

2. The installer fail mode is totally useless. It just says "can't install" with zero information as to why.

Perhaps there is a good reason for the combo being restricted to 10.10.0 (but I bet it's just a bug in the installer), but even it that is the case, it would have useful for Apple to have made that clearer.

Thanks will give it a go.

Agreed.

Been using combo installers since the first Os X release. The next best thing to doing a clean install, IMHO.

98mb disk space available

You really need to clear some space on your hard drive or you will experience some problems. You need to maintain an absolute minimum of 10 - 15 GB of free space at all times so the OS can perform properly (more is much better).

I tested this out by trying to install on a third machine after updating two using Software Update, all of which were running 10.10.1, and it failed as described. Combo updaters have typically not only worked on dot releases but have often been the most stable and provided workarounds for other failed install methods. If this is intentional, I want to thank Apple for deleting another way for things to "just work" when their updates fail. If not, it's just another of a growing list of bugs.

ooops. Meant GB.

Ahh, that's better!
