Recently, I had a need to know if any files or folders had been modified or created on an HFS+ volume in the past N seconds. There are many ways you could generate this type of information on Mac OS X.
To begin with, you could try asking Spotlight.
Besides Spotlight, Mac OS X has a rich [...]
Version 1.5 of MacFUSE is out.
The CHANGELOG has details of what’s new.
I discovered a bug in hfsdebug. It causes hfsdebug to crash while printing Access Control Entry (ACE) details for certain files or folders. For example, consider the standard ~/Library/Preferences/ folder on Leopard.
$ ls -lde ~/Library/Preferences
drwx——@ 167 singh staff … /Users/singh/Library/Preferences
0: group:everyone deny delete
This folder has an ACE for the group everyone. In particular, [...]
A Myth That Won’t Die
Quoting my Google Mac Blog post in its entirety:
A new version of MacFUSE is now available. As always, you can download a ready-to-install prebuilt package, or browse the ready-to-build source. Besides bug fixes and other minor improvements, there is a major new developer feature in this release: an Objective-C framework is now part of the [...]
A while ago, I wrote about procfs for Mac OS X, a MacFUSE-based file system. Subsequently, I added more cool features to my procfs implementation. Recently, I had reason to demonstrate procfs again and realized that I needed still more cool features. That need led to GrabFS.
In a pinch, GrabFS is a file system that [...]
I found some time today to make a certain feature of HFSDebug work on Leopard. The new version is available for download here. The new version should run on both Leopard and Tiger, but there are no visible changes whatsoever for Tiger users.
If you use HFSDebug, you might have realized that the -m option doesn’t [...]
A new release of MacFUSE is here. There is a new version for Leopard, a new version for Tiger, and a new version of sshfs.app that runs on both Tiger and Leopard.

I don’t have an iPhone (and don’t really intend to get one), but for the iPhone-equipped curious operating system investigators, the iPhone Restore image downloadable from Apple’s web site has plenty of interesting details about the hardware and software composition of the iPhone, how some of the things work, and so on. Enjoy.
(Hint: Looks like [...]
Several years ago, while I was working at the IBM Almaden Research Center, we came up with a security mechanism called the Assured Execution Environment (AxE). We had implementations for Windows XP and Mac OS X. (Although AxE supports code signing as a feature, it’s not the same—in any case, this was long before code [...]
A few weeks ago, I released as open source a MacFUSE-based process file system for Mac OS X.
I recently added several new features to this procfs implementation. Some of these features are "cool" in that they put a new twist on certain types of visual information.
For example, there’s a folder /proc/system/hardware/displays/ that contains a subfolder [...]
We did a MacFUSE talk at Google last week:
Video on YouTube
Details on taking a snapshot of the memory and register state of a running process on Mac OS X, including source for a user-space program that does that.
People are welcome to join us at Google on Thursday, May 24, for an open-to-public talk on all things MacFUSE. I’m told that “Doors open at 6:30PM at Google’s Mountain View campus. Guests should plan to sign in at Building 41 reception upon arrival. Refreshments will be served…”
Here’s an abstract:
File systems provide one of the [...]
I’ve made available a MacFUSE-Based process file system for Mac OS X. Source code is included.
I just realized that my “posting” of the link to this nice tech video never got posted (network glitches are common in my current location).
The prolific Mike Pinkerton, who is the tech lead of the Google Desktop for the Mac project, made this video demonstrating some neat features of the product.
