Let me save you some pain:

Or, you can use QEMU builds provided on this forum instead of the custom UTM variants.

Warning that 10.14 isn't very fast on QEMU, but it's usable, unlike Catalina.


A friend pointed me at these as well, and I'm still getting ...

I could'a sworn our hard drive (German System D1-6.0.7 and 7.x) was always called "Festplatte"? But maybe we renamed it first thing after each install and I just forgot. It was kinda cool that you were able to choose your own name.

Does anyone have any suggestions on running MacOS 10.14 "Mojave" on an Apple Silicon Mac? I'm trying to follow the guide at https://khronokernel.com/apple/silicon/2021/01/17/QEMU-AS.html but the screenshots are from an older version of UTM.

I think I've managed to fiddle things so it boots into EFI ...

Just had this crash, and thought I'd post it here in case it helps tracking down some issue. Looks like Thread 3 is calling into SDL somehow and that causes removeFromSuperview: being called on a non-main thread. Not sure if sigsegvhandler is a segment violation in the emulated code, or outside ...

I just checked the source code, and noclipconversion will probably fix the issue with the "tm" disappearing. I misunderstood what it does, and it seems that converts MacRoman to ISO Latin, and ISO Latin has no "tm" glyph.

Not sure yet why nothing but text seems to work (except for apps that keep ...

I think this is a general clipboard issue. It seems text gets copied all right, but gets converted to the Windows clipboard (and converted back when pasted, which might explain the loss of the "tm" symbol). All sorts of images in the system clipboard just never get copied to the clipboard (e.g ...

As an aside, you can use the QEMU-system-m68k custom builds on here to that purpose: I believe it should support snapshotting if you use a qcow2 volume, and emulates a Quadra. That way, you can just pop open the monitor and do a snapshot before testing, then revert if you corrupt HFS.


Wasn't ...

Hi,

I tried to do some System 7.5.3r2 C programming on Basilisk II on MacOS X Monterey. When I write the inevitable bug and it crashes, it always corrupted my entire boot disk image. I've managed to work around that a little by putting the files I'm working on on a separate disk (that way I can ...

Right now, DingusPPC can boot off installation floppies from the System 7 era. I'll be implementing whatever I can for hard disk support next.


Looking forward to seeing how it works. I really want a System 7 emulator I can play around on, ideally without using the boot disk whenever my ...

Thanks! I didn't really think that people would just look at how other open source OSes that ran on the same hardware would do.

We also had to dissect the Power Mac 6100 ROM

Cool, thanks for all those resources!

Hi,

just wondering if anyone knows why HyperCard's visual effects (transition effects from one page to the next) don't work in SheepShaver? My guess is they use some low-level tricks or at least assembly language to achieve decent performance, and that somehow passes by whatever SheepShaver uses to ...

Instead of starting with a "random big file", did you try starting with a new disk image created with SheepShaver preferences in OSX or with the SheepShaver GUI in Windows?


Thanks, that works! I wasn't even aware that this button was there. I distinctly remember hearing somewhere "oh just ...

That sounds cool. I'd be curious in hearing where one would even start with such an emulator. I'm currently working on a HyperCard clone, which involves a bytecode compiler for HyperTalk, and I have a manual for some Mototrola PowerPC CPU that Apple never used, but where do you even find details ...

This used to work, but (I think since I updated to the newest Windows version) SheepShaver for Windows will not read files generated by the Mac version and vice versa. However, when used on the same OS they work fine.

Test setup: Newest SheepShaver for Mac on 10.13, Newest SheepShaver for Windows ...
