Retrospect Errors

Dantz: Mac OS 10.2 (Jaguar) Support and Retrospect 5.0.236 and 5.0.238

4. Error -40 on clients running Mac OS X 10.2.x. Retrospect generates an error: “Can’t read file retropds.22, error -40 (file positioning error)” resulting in the “retro22.pds” file not being backed up. This file is necessary for the Retrospect client software to operate correctly. Dantz is working with Apple to solve this problem. In the meantime, the Retrospect client software should be reinstalled manually following a Mac OS X 10.2.x system restore.

Cheap sendmail setup

macosxhints – Set up sendmail to run in send-only mode

If you are going to not blame sendmail, then there are two ways in which we can administer this medication. The first is to edit the /System -> Library -> StartupItems -> Sendmail -> sendmail startup script in order to use the following commands to start up sendmail:
-OdontBlamesendmail=GroupWritableDirPathSafe -bd -q1h
-C /etc/mail/ -q1h

This does a pretty good job. However, some of the other commands…

10.2.5 Update Problem

MacFixIt – Troubleshooting Solution for the Macintosh

Warning: Mac OS X 10.2.5 installer failure with Software Update
This warning should be heeded by all users attempting to install a fresh copy of Mac OS X, then use Software Update to upgrade to Mac OS X 10.2.5.

If install any iteration of Mac OS X prior to version 10.2.3, then attempt to run the automatic Software Update function and install all available items, the application will automatically install every update listed – including several component updates that made their debut after Mac OS X 10.2.3 – and then Mac OS X 10.2.5. In at least a handful of confirmed cases, the Mac OS X 10.2.5 updater will then fail to install. The Mac OS X 10.2.5 combo updater will also fail to take.

We have tagged the problem to QuickTime 6.1.1, but more than one updater may be at fault.

The easiest solution to this problem is to install the 83 MB Mac OS X 10.2.5 combo updater before installing any other items available in Software Update. If it is too late and you have already gotten to the point where the Mac OS X 10.2.5 updater continually fails, try installing the Mac OS X 10.2.3 combo updater first and then move to 10.2.5.

Classic Shared Memory Limitation

An Apple Knowledge Base article notes a Classic memory limitation that is a major difference between this mode and the real Mac OS 9: Mac OS X 10.2 limits the amount of memory shared among all running Classic applications to less than 128 megabytes.

Disable Specific Software Updates

found on Mac OS X Hints…

In the midst of playing around with the newly discovered Software Update log file (see the recent hint), I also found out how to remove those annoying notices that pop-up when you try to quit Software Update without installing all the updates. In my case, it’s the AirPort update on my desktop G4. It shows up every time, and when I quit the updater application, I get a warning dialog about “are you sure you want to do this even though you haven’t installed this update?”

Like a few others published this week, this tip is probably blatantly obvious to many people, but I’d never previously looked at the menubar in Software Update. If I had, I would have seen the Update -> Make Inactive option. If you simply highlight the package you’d like to ignore and then select this menu item, you’ll get a dialog box warning you that you won’t be able to update this package while its inactive. Click on Make Inactive and that’s the end of the warnings when you quit Software Update.

If you ever wish to update the inactive package, select Update -> Show Inactive Updates and then reactivate the package(s) you are wish to update.

Again, my apologies if this was obvious to everyone but me, but I had no idea you could ignore updates!
