Apple releases Leopard 10.5.6 – Always make a back up before applying a new update

MacMedics Locations in Severna Park & Lanham

Apple released 10.5.6 yesterday. It’s a major update. When you go to install it, ensure you follow Apple’s advice:
1. Back up your computer prior to installing any updates.
2. Quit any open applications before starting the installation.
3. Do not interrupt the installation process.
4. You may experience unexpected results if you have third-party system software modifications installed, or if you have modified the operating system through other means, or if you have moved Apple applications from their default locations
This is all sound advice – we highly advise that you follow these four items. To read more about the update be sure to see Apple’s page on it.
These guidelines are pretty much the same as ours here at MacMedics. What we often see is that a major system update will cause one of two issues.
Running an update may seem like a good idea, but beware! Very frequently an update will cause an issue with a major application like Quark or InDesign, and cause a problem during production. That’s never a good thing. Never run a major update during a deadline, and don’t run an update to try and solve a larger issue without knowing what that problem is.
The other thing we often see is that an update like this can be a heavy duty workout for a sick or dying hard drive (see to learn more on this). Ensure that you’ve got a healthy drive before you run the update. Repair permissions, boot in safe mode, check things out, unplug external devices, and make sure you have File Vault or any other encryption software turned off.
Make sure your data is 100% backed up, and do that by actually checking your back up to ensure your data is where you think it is. If your back up is bootable, try booting off of it to check to see if its working. You don’t want to find out you can’t immediately bounce back from a problem if one should pop up. Sadly Time Machine is NOT a bootable back up, unless you have another system you can test on, but be sure you check it and maybe try pulling a few sample files off of it to test it’s validity.
If your Mac is on MacMedics Scheduled Service, then we’ll perform this update for you when we deem it safe. If you like to live up to the second, follow us on Twitter to watch what’s going on with us and the very latest updates.
