I use mountain lion 10.8.1
I try start disk utility it only says: "You can't use this version of the application Disk Utility with this version of Mac OSX. You have Disk Utility 12.1"
OS X Mountain Lion (10.8.1)
Mountain Lion uses version 13 of Disk Utility.
Where i get that?
For one place, in the Mountain Lion Recovery Partition. Reboot the computer while simultaneously holding down the Command - R keys and when booted select "Disk Utility." You can run the Repair Disk for the computer from there.
Hope this helps 🙂
Did you instal Mt Lion over the top of Lion?
If you di then I'd do another install of Mt Lion over the top of your current install. It would seem the DU app didn't get replaced by the one for Mt Lion.
Yes. i update lion to mt lion. After this update this problem come.
I try install again. (how?)
Look for it in your Utilities folder, inside of your Applications folder. You're probably using the prior version of Disk Utility that was moved out of its proper location.
To do a Reinstall of the OS boot to the Recovery HD, Command+r key at startup, then select Reinstall Mac OS X. the files will be downloaded from the internet and then the instal will begin.
With Mt Lion it is also available from the Mac App store in your Purchases area. You may be able to download it and then nmanually starting the install while booted to Mt Lion.
But I'd normally use the Recovery HD as that takes the installed OS out of the picture.
Thanks for everybody.
There are old version in Applications folder and new version in Applications/Utilities folder.
If there is older versions of Disk Utility in the Applications folder you can Delete them.
This is the first time I have heard of Disk Utility being found in the ROOT of Applications folder. They should not be there and that is why they were not overwritten by the newer version, as the one in Applications/Utility was overwritten to the newer version of DU.
Thanks Lanny. I was having trouble installing and formatting a new Hard Drive and I got the message I couldn't use Disk Utility. I started browsing this forum and found your Reply. Following your advice I went to Utilities>Applications and found a newer version. And all went all. Yes I had recently upgraded the OS. Tom
I know this is an old thread but thought I better comment as I had a similar problem with Mavericks 10.9.5.
The older version was in the utilities folder.
I usually do a fresh install on a clean or new disk.
However, I also use Apple's Migration Assistant to bring over the applications and data to the new disk where the new OSX is installed.
I had this problem today even though the Disk Utility App was in the Utilities folder.
I am going to guess it was due to using the Migration Assistant but I could be wrong.
disk utility "You can't use this version of the application Disk Utility with this version of Mac OSX. You have Disk Utility 12.1"
