The newest v3.1.1 does not want to mount on my Mac. It just says it couldn't.

I have 10.5.4.

How can I solve this?

If it's the US English version for Intel, then compare the output of the following with the results for your DMG. If it doesn't match then you need to download again.

md5 ~/Downloads/OOo_3.1.1_MacOSXIntel_install_en-US.dmg

  MD5([..]) = d20e8ad6f0d8e93860f1ea2cd2371c86

A link to checksums for other downloads can be found at the download page.

+1 checking MD5 or SHA1 checksums is highly recommended for downloads like this – Steve Folly Nov 16 '09 at 20:43
OK it's corrupt. I got a totally different one, efe07e22a3c6f79dfac6e85e753f3cf0. – Deniz Zoeteman Nov 17 '09 at 18:05
It could be different if it is a different file (like different version, language and so on), but given your problems I assume the download indeed failed. The list of all 3.1.1 checksums can be found at but yours is not listed. – Arjan Nov 17 '09 at 18:29
No, that's not the prob. it is indeed perfectly the same file as you have entered in your answer. Thanks. – Deniz Zoeteman Nov 22 '09 at 14:46

Try using PowerISO. Scroll down to "Other Downloads" and download PowerISO for OSX.

If you still can't mount the dmg, rebuild Launch Services by trashing the following two files in the Macintosh HD > Library > Caches folder: and The "nnn" in the second file name is going to be your User ID number, but that probably doesn't matter.

Restart and OS X will rebuild Launch Services.
