"Reconnect" Tip Broken under 10.6
Authored by: WaltFrench on Sep 27, '09 05:58:28PM
This hint seems completely undone under 10.6.

First, fsaclctl seems to have gone missing. Some posts suggested there's a replacement fsacl but no man page that i could find.

Second, I'm concerned that the output of xattr showed 37 hex pairs, not the 32 hex digits and dashes. By the looks -- I've forgotten all my ASCII -- it is a hex representation of the actual hex UUID (43 41 ...) and its dashes (2D), terminated with 00. That's arguably the same as the UUID, but not quite close enough to give me the warm & fuzzies.

So, a show-stopper. Has anybody figured out how to proceed under Snow Leopard?

Maybe I have a solution

From what I have gathered, an extended attribute in Snow Leopard can have as a 'default' representation hex OR ascii.
(1)Take a screenshot and run xattr -p com.apple.metadata:kMDItemScreenCaptureType Screenshot.png on it. You will get a hex representation. Run xattr -l on it and you get both hex and ascii.
(2) Create a new textfile in TextEdit and run xattr -p com.apple.TextEncoding File.txt on it. You will get an ascii representation of it. Run xattr -l on it, and you still get only ascii. Run xattr -px or xattr -lx on it and you get both hex and ascii.

This what I mean by having either a hex or a ascii representation as a default. Now how can be set things for both variants? The simple xattr -w nameofattribute value filename sets an attribute with ascii at the default view. But xattr -wx nameofattribute "valueinhex" filename sets an attribute with hex as the default view.

So far, pretty straightforward. But most extended attributes with hex as the default view run into multiple lines. I have so far only found somewhat of a kludge to set these: Create a multi-line environment variable in hex form and use this together with -wx. I'd be glad if somebody showed me a more elegant way of doing this.

Whether that makes this hint workable under Snow Leopard, I do not know.

Forget about that environment variable kludge

These newlines are not actually new lines. Just enter the full hex string as an argument to -wx.

My MBP was replaced with a iMac and opening Time Machine gave this;

which may work for Drive Replacement but guess it depends if it picks up the new MAC for the HD
