 # Troubleshooting Notes
 
+## Patch checker
+It is important to re-patch ESXi after any upgrade or patches have been deployed. The status of the unlocker patches 
+can be checked using the `check` command in the unlocker folder.
+
+If the patch is installed and matches the current ESXi version, the output would look like this but the version numbers
+may differ on your host depending on any patches installed.

+If the patch is installed and does _*NOT*_ match the current ESXi version, the output would look like this and an error 
+is displayed. You must relock, reboot and unlock the host to ensure patches are applied to the correct version.

+The unlocker from 4.0.3 should allow macOS guests to be started from vCenter on the patched host. If you get an error

+2. Remove and re-add the ESXi host in vCenter

 A patched macOS AMD kernel must be used to run on older AMD systems, but there is a workaround if you have a modern
