Sheepshaver boots Mac OS and closes itself after booting

Post by nex86 »

I downloaded the latest version of sheepshaver and try to boot a Mac OS 9.0.4 image,

I get the system to boot (Starting up...), but right before the Desktop comes up, the emulator just closes itself without any message.

I only get it to work when disabling JIT compiler, but then it's very slow !

The stderr.txt file shows the following:

Code: Select all

I'm running the Emulator on Windows 8.1 X64, System is a Core i5-2500k, 16GB of RAM.

edit: it works when lowering the Memory to 32MB but then I'm getting a no enough virtual memory message.

Was the disk a fresh install? If not, try booting without extensions (pressing shift key during bootup), open extension manager, select "Mac OS 9.0 base" in extension sets, and try booting with that. If it works, then there is an extension conflict somewhere. But my experience with SheepShaver on x64 systems is to disable JIT, or it's to fast for me.

Hi,

SheepShaver tries to reserve the amount of memory you set in the GUI in one continuous block on the host. If you have many programs running it can happen SheepShaver is unable to do so.
Please to run with more memory after a fresh start of your host, and try to stop as many programs running in the background as you can.

Best,
Cat_7
