Why is Screamer needed for sound support on PPC Mac OS, but not for 68k Mac OS?

Compiled and set up QEMU 8.2.0 RC1 for 68k, and everything seems to work great in Mac OS 7.6.1, including sound. However, as this is on the main branch, I am just curious: what is different about emulating PPC Mac OS that requires a whole separate fork of the code (that never seems to get merged int...

Re: The UTM Thread

On my M1 Max, it takes closer to 60 seconds. It's odd. It also performs reasonably responsively on the M1 Max, whereas on the i9 you get things like clicking on the Start button and then waiting 13 seconds before the menu opens. Not very pleasant. I wonder there is some odd magic going on and -acce...

Re: The UTM Thread

Thinking it might have been the fact that the stable version of UTM, 4.2.5, uses an older version of QEMU, I just tried it with the 4.3.1 beta. Unfortunately, it still takes around 6 minutes to get to the desktop on my i9 with -accel tcg. So, it's got to be either something UTM is doing in wrapping ...

Re: The UTM Thread

... okay, that's weird. Instead of using UTM, I decided to try it using qemu from homebrew, using the same command line you used and it took... 39 seconds with -accel tcg, almost exactly the same as yours. With -accel kvm I get an error message: "qemu-system-x86_64: -accel kvm: invalid accelera...

Re: The UTM Thread

Yeah, and the x86 code for the TCG emulator must be bad. I know the M1 Max is faster than the old Core i9 Macs, but not this much faster. QEMU's JIT is quite advanced, including its own optimiser, and is well-known to be one of the quickest around. What sort of numbers are you seeing? I have a test...

Re: The UTM Thread

I think I figured it out; instead of adding the install image as a CD/DVD ISO, I converted it to a raw image with qemu-img and mounted it as a plain old drive and it boots again. Makes sense; the usual way to use the images made by createinstallmedia is, after all, to image them onto a USB stick, wh...

Re: The UTM Thread

Weird question: does anyone else notice UTM running x86 emulation on ARM much faster than it does on x86_64? I just gave it a try on my sorta-new M1 Max (almost as good as an M2 Max, but at a crazy $1,400 discount on the model with maxed-out RAM), firing up a Windows XP VM I already had lying around...

Re: How to transfer files from Windows host to Mac OS 9.2.1 guest.

Update: I found out that standard ISO discs are actually compatible with Mac OS 9.2.1. Must have been the first version of Mac OS to support them. But obviously, it isn't all that efficient to make an ISO image for every file you want to transfer, especially when it comes to transferring files from...

Re: 23-08-2019 New Qemu for OSX with sound support available

Hey, this is working great! Kudos.

BTW, for anyone else struggling to get the sound support to work properly, I've discovered the trick; you have to turn Virtual Memory on in the Memory control panel. With VM turned off, Screamer doesn't seem to work, but if it's on, it works great.

Re: Work in progress by David Ludwig: BasiliskII port to SDL

I've seen a number of similar reports to that -- I wonder if BII doesn't like APFS or is taking some sort of shortcut that APFS doesn't understand? I don't think it's APFS, since it was working with me with APFS earlier. It started crashing at about the time I installed the 10.13.3 update, although...

Re: Work in progress by David Ludwig: BasiliskII port to SDL

I am finding that since the macOS 10.13.3 update, if the "Unix" shared folder is enabled, Basilisk II crashes during boot. If I turn that feature off, everything works. So perhaps you should try disabling the shared folder and see if that solves your issue.

Re: Virus in System 6 Hell

The thing that impresses me is that it can apparently scan into the resource fork, something that's relatively obscure, platform-specific, and already obsoleted at the time Avast! was ported to the Mac.

With all that said, it's pretty impressive that Avast is able to detect such ancient things as resource-fork Mac viruses from the 80s.

I don't think there's much danger of Apple switching architectures any time soon, since ARM can't match Intel's performance at the moment, and in order to pull off the transition in the way Apple's done it in the past, ARM would have to greatly exceed Intel's performance in order to run any kind of ...

Re: Effect of phasing-out 32-bit apps?

CodeWeavers makes a lot of money on CrossOver, which is based on WINE. So just based on that, I can't imagine a plan to make WINE 64-bit-compatible isn't already in place.

Re: GSOC qemu Boot Mac OS >= 8.5 on PowerPC system

To use the built-in networking to connect straight from OS 9 to the printer, you'd need an OS 9-compatible printer driver, which unless the printer is very old is unlikely to exist these days. What I do know is that the LaserWriter 8 driver is very flexible. Back when Classic was still a thing, I ha...
