5/28/08 MacMedics Alert on Leopard (10.5.3)

10.5.3 was released on Wednesday. We're advising our clients not to install this update yet. There are two issues that seem to be related to this recent release. The primary problem appears to be an issue when saving a CS3 document to a server. When users attempt to save a file on a server, the file becomes unusable, even when copied back to a user's Mac, and then opened locally. The issue occurs regardless of the format and doesn't appear to occur for locally saved files, which can still be saved to the server later. The corrupted files appear to have a modified header that prevents them from open properly. In some cases choosing "Save As" to register changes rather than the standard "Save" command seems to work for some folks. There also appears to be an issue with graphics displaying properly on on MacBooks, and MacBook Pros.

Upgrading to Leopard and installing any OS software update

Running a software update as soon as it pops up is not always the best plan. In our travels we very frequently see clients who have run a software update without planning ahead for it, and as a result end up with annoying issues, sudden incompatibilities, and even data loss. One thing to consider is how healthy your hard drive is overall before running an update. Never try to solve an issue such as system lock ups or crashing by installing the latest update, as symptoms like those can be exasperated by applying a software update.

Here's our safety checklist for running software updates or installing a system upgrade.

1. Back up your data, and double check your back up before installing any update. [Don't forget to unplug that back-up before installing an update]
2. Repair permissions - It's not going to hurt anything, so a quick permission repair is always a good idea.
3. Disconnect any USB or FireWire hard drives, devices, or hubs.
4. Make sure you have enough free space on your hard drive - A safe bet is to have 10% of your total hard drive free.
5. Quit all applications while running software updates. The updates should be the only process running.
6. Consider the possibility that major applications and/or features might be affected by an Apple software update or system upgrade.

Don't run a software update on a production machine while on a deadline. You want to be certain that the update will not cause more problems than it was designed to fix. If your machine is working, let it continue working as is, and plan to install the update after you know it's not going to cause any issues for you. We install the updates on our test machines here at MacMedics as soon as they are released to Apple Developers, and again when they are released to the public. Let us be the guinea pigs. We'll let you know how we feel about the update in our weekly e-mail to MacMedics clients.

Can your hard drive handle Leopard?

Installing a new OS is like taking your hard drive to the gym. It can be quite a workout for an older hard drive, and whenever a new OS comes out, we always see a few dead hard drives as a result. No matter what you do, make sure you have a back up of your data before you begin!

Prices have dropped significantly on hard drives over the last year or so. MacMedics now recommends retiring hard drives after three years in desktops, and two years in laptops. Be sure to check out new web page to find out why you should retire your older hard drive and to learn about our 5 rules of data protection and preservation. Why take a chance with your data when faster, larger, and generally more reliable drives are available. Moving to Leopard is a great opportunity to get a new drive, while at the same time insuring your data is safe.
