On May 26, 2009 Apple release it latest update for Leopard, Mac OS X 10.5.7. The update includes general operating system fixes that enhanced the overall system stability, security and compatibility of your Mac. Users considering the update should follow the best practices guidelines below before proceeding with the Software Update or with a standalone installer.
Along with the guidelines I want to follow-up with a problem that came up after updating a group of Mac Pros. I followed my best practice guidelines, listed below, but still ran into trouble after installation. I am including my troubleshooting steps that I used to get the system operating again without having to re-install Mac OS X.
Recommended Steps Before Installing
- 1. Backup your computer prior to installing any new software or updates, either using Time Machine or some other third-party software.
- 2. If you have third-party system modification software installed or have modified the operating system through other means you may experience inconsistent results.
- 3. Shutdown any processes and quit open applications before using Software Update or running an installer.
- 4. Do not attempt to quit or interrupt the installation process. This could result in a partially modified system leaving your Mac OS inoperable.
- 5. Repair Permissions using Disk Utility before and after installation to check for any inconsistencies or differences.
- 6. If something stops or interrupts the installation process you will need to troubleshoot this by checking your network settings, permissions or even installer version.
Disk Utility Stopped Repairing Permissions After Update
I typically recommend that you Repair Permissions before and after you install new software or run an update. This way if something goes wrong you can rule out certain contributing factors. In one situation I ran across updating a Mac Pro 3Ghz Quad-Core Intel Xeon with Mac OS X 10.5.6 Leopard installed to Mac OS X 10.5.7 third-party applications stopped responding. Before starting the update I Repaired Permissions and performed the update using Software Update. After restart I ran Repair Permissions again on the Mac Pro and received the following Error: The underlying task reported failure on exit. Typically this rare error indicates that you hard drive has issues that Disk Utility cannot fix. (See Apple’s Support Forum article TS1901.) The suggested repair by Apple is to perform an Erase and Install installation. As I find this to be the last resort when repairing a Mac and my operating system was still responding to other commands I performed the following repair steps:
- 1. After the Disk Utility failed I restarted the Mac Pro and booted into Single User Mode by holding down Command + S.
- 2. After the #root prompt I ran a file system consistency check with fsck-fy. On completion type reboot after the #root prompt.
- 3. Before your Mac comes fully online again hold down the Shift key so that the system can launch into Safe Mode.
- 4. If your Mac Pro is set to automatic login, let the system completes its start up processes. If you need to login, log into either your account or the most commonly used one. Once complete, Shut Down your Mac.
- 5. Test if you can Repair Permissions by booting into Single User Mode again by holding down during startup: Command + S.
- 6. After the #root type the following:
On completion, type reboot after #.
- 7. Once your Mac Reboots and you are logged in again try running Repair Permissions.
- 8. If this fails try running the downloaded Mac OS X 10.5.7 update from Apple’s website as a stand-alone installer.
- 9. After the update is installed Restart and run Repair Permissions again.
This should resolve the problems caused by the Software Update installer. Overall the Mac Pro I worked on is performing well. I ran a system check using a third-party system analyzer and found no more errors.
