A new release is up at the MacFUSE project page.
0.2.0 adds several new features and fixes several bugs.

On Mac OS X Viruses

Sunday, November 5th, 2006

I usually find the security-related smugness of Mac users rather jarring. What’s often even more jarring is the reasoning behind such smugness. That said, I have to say that the recent furor regarding the so called OSX.Macarena “virus” amounts to, well, bullshit. If anti-virus companies are pretending to “recognize the threat” and therefore attempting to [...]

A Technical History of Apple’s Operating Systems

Sunday, July 23rd, 2006

The very first chapter I wrote for Mac OS X Internals: A Systems Approach was the “history” chapter. My goal was to create a comprehensive and detailed book. I deemed it important for the reader to understand the long and eventful journey toward Mac OS X. Therefore, I wrote the chapter as a technical history [...]

BAMBIOS: Legacy (BIOS-Based) Booting on the Intel-Based Macintosh

Monday, March 13th, 2006

We have developed software (“BAMBIOS”) that allows such legacy booting on the Intel-based Macintoshes. For example, a regular (that is, non-EFI) version of Linux can be readily booted using this software.
A mini presentation on the design of BAMBIOS is available.

Update: VMware Workstation, Windows XP SP2 in a Dual-Processor VM

Thursday, February 23rd, 2006

This is a rather trivial update, but here are some points of interest:

Knoppix seems very stable overall.
We fixed the pixels-per-row vs bytes-per-row discrepancy in the kernel, so the X Window server has precise information now.
We have tried VMware Workstation and VMware Player. Both work really well.
This is a screenshot of VMware Workstation running a dual-processor [...]

Windows XP (VMware) on the Intel-based Macintosh

Tuesday, February 21st, 2006

Yes, it works. In fact, it works really, really well (performance-wise).
Please go here for the initial announcement and a customary screenshot of Windows XP running under the Linux version of VMware. The hardware in question is a 17-inch iMac.
