I'm surprised Apple is STILL saying this BS about the Desktop Manager INIT (henceforth referred to as DM) not being supported. It has been around for quite some time (as long as AppleShare?) and it results in a tremendous (orders of magnitude) reduction in the time it takes to update the desktop. I suggest ANYONE with a hard disk who sees the dialog box "Updating Desktop..." for more than 5 seconds when copying a new application to give DM a try. > It speeds up access to desktop information because it replaces the >normal desktop file which uses the Resource Manager and replaces it with >"B-Trees". I can't remember the last time I have questioned a posting from someone at Apple, but the two slips on HFS and floppies makes me reconsider this person's credibility. Have you ever run Disk First Aid, typed COMMAND-S and then checked out an HFS volume (floppy or HD)? It does several checks of "B-Trees," which leads me to believe that the Mac OS is already using B-Trees, so the question still stands - how does DM do it's stuff? What is it about DM that Apple doesn't want us to be using it?!? I have not had any difficulties with DM with release 5.0 or release 6.0.2 (and probably initially with sys 4.1/5.3). > I was assured that future versions of the Finder will deal more >effectively with the desktop issue, but that for now its use at your own risk >if you want the speed up the Desktop Manager can provide. I'm curious what "risks" our file server is NOT in, compared to the risks that my own Mac+ COULD BE subjected to. Or, twist that the other way around - what "risks" could our file server be in if it's running software that "works only for one specific condition" (Appleshare)? > As for myself, I'm going to test it out... Do so. I have been using DM since two weeks after I bought my HD at the beginning of this year. I will not give it up!! I do offer a few suggestions, however: [what happens with DM: After copying DM into your system folder, reboot and you should find the two new files "Desktop DB" and "Desktop DF". They are invisible. (I'm still waiting for someone to cry "Virus! Virus!" on these files. :-)] You do not need your old Desktop file any longer; you may delete it. As mentioned before, if you boot off a floppy that does NOT have DM in the system folder, you will have that opportunity to get that CCU (Carbonated Caffeine Unit) while a new and complete Desktop file is created. This is bogus. What I have done is delete the (big) old Desktop file and copy the desktop file from a freshly formatted HFS disk to my HD. Now, when I boot off a floppy w/o DM, the Finder will "find" a desktop file and have no need to recreate one. Naturally, at this time w/o DM, most documents will not have their application's ICONs linked. That's OK, since I usually only boot off floppy for special temporary reasons (e.g., file recovery, make backups, or when I just can't deal with all those nifty INIT's). Without DM installed on bootup, when you open folders on your HD that contain applications, they will be added to your "fake" Desktop file. This is basically the same thing as when you copy a new application or rebuild the desktop: applications are searched and their Finder attributes (icons, type/creator links to data files) are added to the Desktop file. In summary, if you don't want your old Desktop file to take much space, don't let the Finder "see" your applications when you are NOT running with DM. Note: I have not seen any conflicts with DM's desktop files and keeping the old Desktop file around. In fact, I have not had any situation which I can specifically attribute DM for crashes or other Mac strange behavior. The Desktop Manager is (was?) a terrific opportunity for some third- party to market a functionally equivalent INIT. As you have probably read here, Apple has plans to do something about the Desktop file. Whatever they do, I hope it maintains compatibility with Desktop Manager! (just kidding...it should be BETTER! Save Comments!) But when will this come about? System 7.0? Due when? With what new features? [Do you feel it getting warm in here? Furnace must have come on...] Reflecting on 6.0.2: I can't tell you how incredible I think the Notification Manager is...and how about that Sound Manager, gang? Oh, and those new dialog boxes indicating which drive the Mac II is formatting -- as if it makes a difference at that point -- makes my mouse run in circles on it's pad. Worthy of a major release? I'm sorry, but I'm pretty disappointed with Apple's releases of system software since 5.0. MultiFinder was big stuff -- certainly worthy of a new release number. Bug fixes and/or small enhancements should be 5.1, 5.2, etc. Release 6.0 was a letdown (actually, I never let the 6.0 disks come NEAR my CMS SD60 hard drive much less actually TRY it.) OK, this is getting off the subject, but I really wanted to express my feelings...maybe even spark a new discussion!
