Now if the resource fork is missing, it may still work, but no guarantees. That should at least get it to be recognized as an application. The only way that I'm aware of how to change these fields is to use ResEdit which was a tool from Apple to tweak all those hidden bits of HFS files.Ĥ. It should be APPL and MOZZ, respectively. But ignoring that, it is probably just that somehow the Type and Creator of your application is corrupt or missing. Hopefully the resource fork is still preserved in your Classilla application (usually a hidden directory when MacOS was mounting a non-HFS filesystem). xls, etc.), but that was easier to fix since you could just rename the file.īut what about applications? Their type was APPL which told the MacOS that it was an application and attempt to load and execute the file directly. Windows achieved this with file extensions (e.g.doc. While this would appear frustrating to more hardcode computer users, it did make things a bit easier for the novice. As such, when you installed an application, it registered itself with the OS to indicate that it could handle files with a particular signature. The idea was that if you had a word processor document on a disk, the file could tell the computer that it needed (say) Microsoft Word to open/edit the file. This feature was achieved by every file indicating a type and a creator. Parallels 7 handled installations of Windows 7 and Ubuntu Linux without a hiccup, leaving only an installation of the Mac Classic emulator, Sheepshaver, to have the Mini able to handle all my computing needs. I am NOT the owner of SheepShaver, I'm just putting together all the files in a convenient project. I'm putting together this package for anyone who wants to use SheepShaver. Sheepshaver Package for Windows: A Mac OS 9 Emulator. Enter a user name, password, password hint, and then select Next. Download Sheepshaver Package for Windows for free. This detail is well hidden from users (as was the intent) and not readily visible as there was no official command line for the Mac and thus it was harder to poke around to find.Īlong with the two forks, the MacOS also had a bit more intelligence about what files were and what application was needed to run them. On Windows 10 Home and Windows 10 Professional editions: Select the Start Windows logo Start button then select Settings (Gear-shaped icon) > Accounts > Family & other people > Add someone else to this PC. How this was achieved on MacOS was the HFS filesystem would split every file into resource (e.g. Unlike Windows or UNIX or most other operating systems that I've used over the years, MacOS tends to pack quite a bit of data into a single apparent file there is a separation from the actual application code from "resources" such as icons, sounds, etc. Usually when you see that message is because the metadata for the file isn't set correctly this is typical if you're looking at MacOS Classic files that are not on a HFS filesystem.īrief Information on Classic MacOS Filesystems
