Make sure that you choose Mail>View>Show Mailbox List, then hover your cursor over one of the subordinate mailbox categories, and you should see "Show." Next click on "Show."OS X Mountain Lion, iPad 3G, iPhone 4, 20GB iPod Color, iPod shuffle

I have the Mailbox List viewable, but the catagory "On My Mac" is not there. I would like to have it like in your sample picture, where I can select "Show" to see my Mailboxes, or "Hide" to hide them, but I don't have the "On My Mac" heading anymore. The boxes are in-line with the Inbox, Sent, and Trash boxes; I can't hide them away. There is no "Show" or "Hide" option next to "Mailboxes" either.

What mail is stored in the numbered Mailboxes? Are those your previous "On My Mac" Mailboxes?
Can you create a "New Mailbox" using Mail>Mailbox>New Mailbox...>"On My Mac?"
Perhaps you can find your previous "On My Mac" mailboxes using Mail>File>Import Mailboxes...OS X Mountain Lion, iPad 3G, iPhone 4, 20GB iPod Color, iPod shuffle

The mail in the numbered boxes is the same as it was in Lion, and they are my previous "On My Mac" Mailboxes. Nothing physically has changed with them; the only thing wrong is the missing "On My Mac" Catagory.
Yes, I can create a "New Mailbox", with "On My Mac" being the location on the mailbox, and when I do, it falls in line with the other Mailboxes that I have had since before Mountain Lion.

I have run out of ideas.
I cannot reproduce the problem on my computer. Since I do not know what the problem would be, I look forward to someone else answering your question.OS X Mountain Lion, iPad 3G, iPhone 4, 20GB iPod Color, iPod shuffle

I had the same issue. I could search and find my emails that were stored on my mac (and not on the server), but could not find the mailboxes they were contained in.
My solution was to place the curser on the "ON MY MAC" label under "MAILBOXES" and to the right, it displayed "SHOW." I clicked on it and, much to my relief, the old emails stored on my Mac showed up.
Hope this helps you.

All right, thanks for your help. Hopefully there will be someone else who can offer more suggestions, as you say.
This was already brought up, and it is not the problem I am having. I have no "On My Mac" heading under which my mailboxes could be hidden. I have all my mail; I'm not missing any. I just want to be able to hide away the Mailboxes when I am not needing them under the "On My Mac" heading. Getting that heading again is the problem.

Been pulling my hair out for hours on this trying every solution on the forums to no avail but finally found something that worked for me.........
As suggested above, I added a new mailbox and selected the location "On My Mac" - the mailbox was created but the heading still did not appear.
However, I then created another mailbox and selected the location to be one of my IMAP accounts and bang! The mailbox was created under a new heading of the "relevant IMAP account" and also the "On My Mac" heading reappeared.
I've now got a mailbox I don't really need but at least I've got the heading back......
Hope this helps!
