Got the error "Lion Recovery Update can't be installed on this disk. An error occurred while evaluating JavaScrip for the package"

Installer Log says Oct 13 10:07:00 Installer[6749]: recoverySystemVersion: could not get recovery version information for mount point /: Unable to find boot helper partition. (-69737)

Sounds like it never got setup in the first place -- now to find out how to set it up? I thought I read this is only supported on newer Macs, so what about Mid-2009 MacBook Pro?

So here's the solution (assuming you don't have a Recovery HD on your internal drive):

To change the Recovery HD to be apple_boot (hidden) do this (assuming you've already cloned over the Recovery HD using Disk Utility from an external drive into a internal drive partition of at least 650 MB):

Get your detailed information on your setup from Terminal:

sudo gpt -r show disk0
diskutil list

To change a GUID partition type to Apple_Boot the UUID is 426F6F74-0000-11AA-AA11-00306543ECAC

First Remove:
sudo gpt remove -i 3 -b 973092480 -s 2894232 -t 48465300-0000-11AA-AA11-00306543ECAC disk0

Then Add:
sudo gpt add -i 3 -b 973092480 -s 2894232 -t 426F6F74-0000-11AA-AA11-00306543ECAC disk0

Problem solved!


In the got remove/add, be sure you plug in the correct -b and -s option values from YOUR setup for the relevant partition!

For folks with both a Lion Recovery Partition and a TechToolPro eDrive partition already installed, Lion Recovery Update (running under 10.7.2) may report that it is unable to create a Recovery Partition and offer you the 'option' of Cancelling the installation.

My workaround was to mount the existing Lion Recovery Partition, using Disk Utility, and then run Lion Recovery Update. Seems to have worked like a charm.

This update is stupidly large. I suspect it's just an image that your current recovery partition is replaced with... It was the same size from Software Update, so it's not just that the standalone is larger.

How about a proper delta update that's not over 400MB, Apple? Surely you didn't re-engineer the entire recovery setup from scratch.

I don't mind downloading 400MB for an update to a fairly minor component of my system, but I know there are a LOT of people who do.

If you have an existing Recovery Partition it can comfortably find, I think it will simply update it with what needs to be updated. Otherwise it tries to create a new Recovery Partition, somewhat along the fashion of Recovery Disk Assistant. It has difficulty understanding custom partitioning schemes: see my Troubleshooting note wrt TTP eDrives.


Hmm, maybe it's because I have FileVault whole-partition encryption enabled. That might be a "confusing" enough partition scheme for it.

Still, I did do a fresh install, no custom partitioning, and used the Security prefpane to encrypt my disk in the first place...
