SheepShaver Wrapper on macOS Big Sur

Post by StephenBEinbinder »

The good news is that I got Sheepshaver Wrapper to launch in Big Sur. The bad news is that it doesn't work when I log in as a root user. No matter what I do, I keep getting the error message: Not authorized to send Apple events to System Events. (-1743). The message contains an edit button and an OK button. If I click the edit button I get a Sheepshaver Wrapper script, which I don't have a clue what to do with. In order to play a decades-old Mac game from a CD Rom, I need to launch Sheepshaver as a root user. At least that's the way it was using El Capitan or Sierra. Are there any ideas out there or am I plain out of luck?

Hi,

The usual way around this is to create a disk image from the CD and add that to the volumes list.

Best,

The easiest way to do this is to use Disk Utility to create a CDR image. You can also do it with dd from the terminal, or with hdiutil from the terminal.

Eh, Cat_7 and adespoton, note that "StephenBEinbinder" is using SheepShaver Wrapper, not a regular SheepShaver setup.

d'oh. The issue appears to be that in the Privacy System Preferences, the application is not authorized to use System Events. This will need to be done to get the wrapper working.

Please pardon my ignorance, but I open System Preferences/Privacy. Then what should I do? Unlock the lock, open Full Disk Access, then check sshd-keygen-wrapper? BTW I thought Sheepshaver Wrapper would be easier to install than the regular Sheepshaver.

The Wrapper makes certain things easier, such as networking, printing, installing an OS, and file transfer, as that's already pre-configured for you. But macOS penalizes apps that attempt to automate the host OS.

So what you need to do is go to System Preferences -> Security & Privacy -> Automation, click the lock to authenticate, and find the appropriate app (sshd-keygen-wrapper doesn't sound correct here, wouldn't it be SheepShaver Wrapper.app or Mac OS 9.app or similar?) and check the "System Events" checkbox. After that, the app can control system events, which allows the wrapper to do file transfer, printing, etc.

That doesn't work. Neither does my own latest shot in the dark. I still get the same error message. It seems impossible to upload images to this forum, so here's the script I get:

Applescript ^ <No selected element>
-- Self-contained Sheepshaver Wrapper
-- Revised for Sierra and later versions
-- Script by Edward Mendelson http://wpdos.org
-- 6 Feb 2019: 64-bit SheepShaver
-- 8 March 2019 rebuilt script, simplified
-- 17 Aug 2019 added Catalina feature (later removed)

-- never change anything below these lines!

End of script. Whew! Now are there any ideas?

Hi,

If you want images to show up here, you need to upload them somewhere and then link to them in your posts.

You started this thread with this:

Why do you want to run this app while logged in as root user?

Eh, because the OP wants to use a real cd rom?

Ronald and Cat_7, I want to run Sheepshaver Wrapper as a root user because that's the only way S.W. can read a CD Rom. Like I said in my initial post, at least that's the way it was under El Capitan and Sierra. I have a CD Rom Mac game from 1994.

Didn't we already recommend making an image of the CD ROM? It'll be faster than using the real thing, you can store it on local storage, and you don't have to worry about scratching it or losing it.

Personally, I've imaged all my CDs, and I can just spin them up as needed in SheepShaver or BII without having to dig out the discs.

I'm the person who wrote the SheepShaver Wrapper, which is written in AppleScript. The internets tell me that you can't run an AppleScript as root.

So, if you insist on trying this, you'll need a standalone SheepShaver setup, not the SheepShaver Wrapper. Anyway, as Adespoton says, you'll be a lot better off using CD images rather than trying to launch physical discs.

Well, I'm halfway there. I got standalone Sheepshaver to work in the root directory, but it now ignores my physical disk. Also, I'm stuck with an empty Untitled directory in root sheepshaver. In my regular personal directory, Disk Utility won't let me create an image. I get this error:

Creating disk image from “Return To Zork” (disk3s1s2)

Operation failed with status 1: Operation not permitted

Operation failed…
***
Probably because that's proprietary software?
However, I did create a disk image from a downloaded version. But that version is somewhat compromised, giving me only sound but no video from mp4s throughout the game.

As emendelson said, the wrapper he wrote is in AppleScript, which isn't "root" compatible. If you want to use the original CD, you'll have to set up SheepShaver from scratch without the AppleScript wrapper.

However, if you're not getting video on the MP4s, that's likely a SheepShaver issue; SheepShaver doesn't support hardware video acceleration, and can run into problems with complex video in software mode. Running from CD won't fix this. Possibly it'll work in QEMU-PPC; it may be a bit slow and stuttery though.

Not sure about the "operation not permitted" bit; it's likely because "Return To Zork" is an HFS mixed-mode CD, and modern Disk Utility doesn't support HFS partitions. Using Toast or 'dd' to image it instead should result in a working image.

1. The latest macOS version in which Disk Utility can create a disk image from such older CD-ROMs is macOS 10.14 (Mojave).

A workaround for creating a disk image from only the HFS partition is here: viewtopic.php?f=1&t=10709
That method is fine for MacOS installation CDs, but it may not result in a useable disk image for the game.

The easiest solution: Get hold of a Mac with Mojave or earlier installed and create the disk image there with Disk Utility. Choose DVD/CD master for the image format. (And create disk images from all your important older CDs.)

2. About how to set up a regular SheepShaver configuration see the manual here: https://www.emaculation.com/doku.php/sh ... os_x_setup

Okay. Here's an update. I'm so close with making the disk image, which does work from the root directory, sort of. In the root directory, with the disk utility, I made several attempts to make a disk image from my E-bay bought copy of the Mac version of Return to Zork. When I returned to my own personal directory, Sheepshaver only recognized the disk image as an empty audio CD. Then I tried the read/write format. Sheepshaver finally recognized the game in that format. There's one glitch. I can't save and restore the games. Maybe because I used the no encryption option? Maybe I need to experiment further. If the encryptions don't work, there's still the Terminal method you suggested, which I haven't tried yet.

If you're using Disk Utility to image CDs, you need to save as CDR "DVD/CD Master" format.

If you use the Encrpytion option, it compresses and encrypts the image, so it's going to be unreadable by SheepShaver.

No, I tried the CDR DVD/CD Master format and Sheepshaver thought it was a blank audio CD.
