Thank you, that's good to know! :)
I was more worried about the fact that there might be a "better" way
to do it (i.e. in the same way that you don't call
"becomeFirstResponder" on an NSResponder, you call the
makeFirstResponder method of NSWindow... but then again, NSResponder
doc insist that you *never* call becomeFirstResponder directly under
any circumstance, while NSToolbar's doc only "suggest" that you
shouldn't call it directly in most cases)
From what I can tell though, there seems to be no other way to do it...

I have to disable all toolbar items during a long process... I did
it basically by overriding
- (BOOL)validateToolbarItem:(NSToolbarItem *)toolbarItem

So that everything is disabled when my process is running, however,
once the process is done, the toolbar items are still disabled
until I somehow click on one of them... only then they become
enabled again...
So I found out that using
validateVisibleItems
Was forcing the re-validation of the items, and making them
available when I need them to be... however, the docs clearly state
that this method should not be invoked directly... therefore, I am
wondering if there is a better alternative to force the re-
validation of my items?? Should I just ignore the doc since it's
working and this is a particular case?
It's OK to call this method directly. The docs and header say you
typically do not call it directly to make it clear that it is called
on your behalf after window update events. If you have something
that changes the valid state of your toolbar items that is not
associated with a window update event (such as a long running
process finishing), then your situation is atypical so the
"typically..." admonition doesn't apply to you.
