After restoring your Mac from timemachine Mail keeps asking you to enter your password and will not connect to your mail.

In the terminal when you run the command ‘codesign -vvv /Applications/Mail.app’ you get the result

‘/Applications/Mail.app: code or signature modified’

Solution

1. Download and install pacifist.

2. Put in your OS X Snow Leopard DVD and open Pacifist.

3. Open ‘Contents of OSInstall.mpkg’ > ‘Contents of EssentialSystemSoftware’ > ‘Contents of Mail.pkg’

4. Click Install.

5. Follow through Pacifist warnings.

6. Open Mail and your email should be working.

If you run ‘codesign -vvv /Applications/Mail.app’

You should get:

/Applications/Mail.app: valid on disk
/Applications/Mail.app: satisfies its Designated Requirement

To remove items from the OS X Menu bar including the Mobile Me icon simply command+ click the icon then drag it away from the menu bar.

The item will then ‘poof’ away.

When preparing your hard drive for an OS X 86 install you will generally need to create an active partition with an id=af using the commands below.

list disk
select disk x [x is the number of the disk where you want to install your leopard on it]
list partition [Now diskpart should tell you there's no partition on the disk, if it show up a partition go ahead and type delete partition]
create partition primary id=af
active
exit

Unfortunately sometimes when you reach the line “create partition primary id=af” you may hit a snag when diskpart brings up an error message stating “the arguements specified for this command are not valid”.

To fix this, you need to go the disk management facility in windows (right click my computer – manage) then storage. Select the disk and right click it, it should now offer you an option to “Convert to MBR disk”. This is instead of GPT. Select this and retry the create partition command. The partition should now successfully create!

When trying to copy files from the OS X 10.5 (also happens in OS X 10.3 and OS X 10.4) to Windows Server 2003 you get the following error:

‘you cannot copy some of these items to the destination because their names are too long or contain invalid characters for the destination. Do you want to skip copying these items and continue copying the other items?’

On the 2003 Server:

Go to Security Settings, Local Policies, security Options.
Disable the following:
Domain member: Digitaly encrypt or sign secure Channel Data(Always)
Microsoft network server: Digitally sign communications (always)
Microsoft network server: Digitally sign communications (if client agrees)

Make sure that the Macs are mounting the network drive with SMB rather than AFP (this caught me out for a while). I don’t know how to fix the error with AFP however samba is good enough to use in 10.5.

In windows you can simply highlight an option and click delete however on OS X you need to click shift+delete.
