I read on the garden that it needs to be locked. Not sure what that means, but I used chmod 444 on the image to make it read-only. But SheepShaver says the disc only works on the original media. This is the image I downloaded: https://macintoshgarden.org/apps/os-904-us The ROM I'm using is the G3 Desktop. Also, I have no sound, but I'll cross that bridge if I can get Mac OS 9 working. I got System 7 kind of working in ShSh, but it's so unstable it's unusable. But my main goal is to get Mac OS 9 working on ShSh. What am I doing wrong here? If anyone could lend some help, I would appreciate it! |

Quote from: ShinobiKenobi: "needs to be locked. Not sure what that means"It means that if you download the archive onto a Mac system, as soon as you extract it (if compressed) you should check to see if it is locked, before doing anything else with it. Especially before mounting it onto a desktop. Usually you only need to select the .iso image and Get Info on it in the Finder, this will show you if it's locked or not, and if not, you can lock it via the info window. The reason why it should be locked, is that the Mac OS (bless it's pointed little head) if the (iso, cdr, img, etc) image you mount is unlocked, the Finder will see it as being a writable disk image and write date and time stamps plus any other dot underscore invisible file it deems necessary, into the mounted disk image. This has the unfortunate effect of making a once bootable image unbootable. Not always, but often enough to warrant that warning. Note: modern Mac OSs may no longer mount HFS images, but left unlocked the Finder on the ROM itself may affect the build by writing to its own disk image. So, if you did mount this image unlocked after you had downloaded and extracted it from the zip enclosure. Then you really should start over with a fresh extracted copy from that zip download. Make sure you lock it first. Now SheepShaver. To have a Mac OS 7.5.3 to Mac OS 9.0.4 working, you must use an Old World Rom - if you only want a Mac OS 8.5 to Mac OS 9.0.4, then you can use a New World ROM. I have used that Mac OS 9.0.4 disk image before and don't recall any issues with it. To boot from it, it can be mounted (using Toast or Disk Utility) on the host Mac, and have the SheepShaver GUI set to boot from CD, It should start up that way. Or, you can add its name to the SheepShaver's list of disks in the GUI, move its name to the top of the list to boot from it. SheepShaver boots from the first System file it finds, reading from the top of the disk list. Anyway, those are basic things you can try.

I can't get any 8 or 9 image to boot on it, so the only one I can try to extract the zip on is 7, which crashes often and randomly. I don't have any other way to extract it in ShSh, so it's kind of impossible for me if 7 can't do it. But I'll try. Thank you

No, don't try unzipping in SheepShaver. You extract these images on the host PC or Mac. Lock them, then add them to the SheepShaver GUI app, to launch them when you start up SheepShaver. Or mount it on the desktop using Toast (if you are able to), but add it in the GUI app's list of disk images if you can't, then start up SheepShaver. I see that image extracts from the .zip as "691-2684-A Mac OS 9.0.4.toast", you can change the".toast" suffix of this one to ".iso" if you don't have Toast.

I use SS on linux and macos x (intel and arm) quite often. I have no idea what this "unlocking" might be. Maybe just to make sure something isn't read only. So first make sure your rom is a good one. Even if you have no install image (such as an iso or toast) and no hard drive image (a dmg or dsk or img, etc) you need to make sure you get it to the "flashing question mark disk" stage. If I were you, and you haven't used SS before, I'd use someone else's hard disk image and make sure you have it running well first. Only then should you try downloading a MacOS install iso and doing your own install. http://macintoshgarden.org/apps/sheepshaver Unrar the images on the host machine. If you can't get any from the above to work for some reason, even if you don't speak french, try this one just for testing http://macintoshgarden.org/apps/mac-os-904-french-sheepshaver I needed to test something in French so used the one right there, so definitely know it works. (Its customized a bit crazily tho, ouais, c'est un peu fou!). Once you've got someone else's image to work, you can try reinstalling the os over theirs, just add the iso or toast etc as another disk in the gui (ie treat it as another hard drive). NOTE: SS can NOT run any 9.1 or 9.2, the highest it goes is 9.0.4.

@MTT I can't lock them in Linux, my host os. That's a Mac feature/option, unless setting the permissions of the file to 444 in Linux is the same thing. But I noticed that even if an image wasn't "locked", the check box not being checked, it still showed a small padlock icon in the upper left of the file icon in the Finder. I also have to extract it with my System 7 system in Basilisk II, because Linux has no idea what .sit files are. I'm making progress, though. I made a volume to use with both Basilisk and SS so I can share files back and forth. This helped me extract files using Basilisk, because for some weird reason the System 7 system on SS can't for most of them anymore, even though it used to be able to with Stuff it expander 5.5 and 4.2. I still can't get 5.5 dlx to work on SS yet. But I got Toast 4 to run, and was able to mount a toast 9.0.4 disk image, but during installation that was running on System 7, it said the help image was corrupted. That was the www DL #32 here https://macintoshgarden.org/apps/mac-os-90-904-update-90-imac-dv-ibook-g3-g4-agp-904-g4-cube-g4-gigabit-ethernet-pb-g3-firewire. I tried the mirror, and that had the same problem. I tried to boot up from it before, but it didn't work. The md5 sum was what it was supposed to be. But now I'm downloading the mirror download. Will extracting the files within the Mac system cause corruption? I'm just curious why it's recommended to extract them with the host system. Thanks for your help! @lauland That's the version I'm trying to install

@ShinobiKenobi: Ah, Linux. OK, I'll unwrap that .sit and upload it as a ".iso" to to the same page that you linked above. Should be there within 30 minutes from this past arriving. You can make it Read Only in a command-line, if you need to. [Erm] The page link for 9.0.4 only point to the image in .zip archives. You shouldn't have any bother with those. They aren't StuffIt ".sit" No matter I'll add the raw .iso to that page, anyway.

#MTT The Mac OS 9.0.4 was a zip file, so I can extract it on Linux. The enclosed file is a toast file, but I didn't know I can rename the .toast extension to .iso. I'll try that and see if SS boots it. I don't want you to have to waste your time. Thank you for your advice! I really appreciate it.

No prob. It's up there now anyway, if anybody needs it  It's the top main download link in that page, not the links in the page description (which are for the zipped copy). Yeah, just rename your downloaded zipped copy's .toast to .iso, and you'll be good to go.

I finally was able to install it and can run Mac OS 9.0.4 in SS now  Although it crashes whenever a web browser opens and tries to access a page. I'm using slirp. I had the same problem in System 7 in SS also. Basilisk II runs System 7 flawlessly, so I might just use that if I want to use System 7. It also has sound, unlike SS. And, it has a scaled screen when I use fullscreen, so everything looks big enough that I can see it. I can still see the small non-scaled screen, it's just smaller, so I have to get closer. If I can get the networking to not crash SS and if I can get sound, it'll be good. I just wish it scaled to the height of my monitor like Basilisk II does, oh well Thanks again!

Good to hear. You could take a look at SheepShaver No Sound (Solved) on the MG. It might help with your no sound issue. SkyCapt's post in that thread hit the right spot for me...

ShinobiKenobi, I’ve felt like a crash dummy trying to setup SheepShaver too many times in certain scenarios, so what helped me out a lot was I started using Mendelson’s pre-configured SheepShaver application to keep my sanity I just read the dos and donts as far as app compatibility and there’s also a System 7 PowerMac SheepShaver version which mimics a PowerPC Mac, which can run more things than Basilisk II! you can even open the MacOS app and grab the included ROM files and disks even and try them on your SS setup, again keeping in mind the compatibility warnings given on the page; just throwing this in here since it’s saved me a lot of time and frustration ever since I started using it over trying to set it up on my own

For quite some time I have happily been using Mendelson's MacOS9 application. It has been stable and functiona;. He includes many features and OS9 applications that I do not use. Recently I have setup both a G4 Mac Mini and G4 Powerbook with Tiger and the Classic environment installed and been very pleased with that setup and have been using it more and more. I do not recall OSX and OS9 integrating so nicely. I use the Drawingboard Theme for Tiger, and the Gizmo theme for OS9. My wireless "Mighty Mouse" scrolls nicely and provides a right click in both environments. Copy and paste wore every where and OS 9 has easy access to my network. Mainly I like to play with all my OpenDoc bits and bobs and they all work fine in Classic. Classic really does set a high bar for seamlessly running OS9 software in OS X at least up until Tiger and using PPC hardware.

Wove, I have thought of Tiger in much the same way actually
