So, there it is an Apple Mac configured to auto login is now showing a Login screen and it doesn’t seem to like any of the usernames and passwords that we could think of. In other words we’re locked out. I haven’t done an awful lot of Mac support, but I do know that it sits on top of a BSD core and because of this I knew we’d have some options. So, of course, the first thing I did was a quick search to try and get started… this post has a lot of helpful info about what to do if you’ve lost your administrator password (setting it up so you don’t have to enter a password for administrative tasks.) But most importantly it gave instructions for getting into single user mode.

Mac OS 7/8/9 troubleshooting
It’s an older platform, but there are still some around. I found this nice guide to troubleshooting startup issues on these versions of Mac’s OS.

Hard drive testing utilities
Windows users know chkdsk, linux users know fsck… users of each MIGHT have heard of SMART. These are different ways of TESTING hard drives. Well, there’s also a utility called TestDisk that looks promising for recovering data… Here’s the clip from their site. “free data recovery software! It was primarily designed to help recover lost partitions and/or make non-booting disks bootable again when these symptoms are caused by faulty software, certain types of viruses or human error (such as accidentally deleting a Partition Table). Partition table recovery using TestDisk is really easy.” It runs under a variety of OS’s and recognizes several different disk formats.

Mac/Linux/Windows usb wireless adapter D-link DWL-G122
One of the tools I looked at having for my expanding kit has been a usb wireless adapter that would work with minimal install on Windows/Mac or Linux. As you can imagine…. it’s not as straightforward as just getting one that’s compatible with Windows…. well, after much searching I found the D-Link DWL-G122 802.11g Wireless USB adapter…. (Revision B it seems is the one to get…) Anyway, using a generic driver downloadable for the Mac it will work (from ralink http://www.ralinktech.com). On linux, you have choices (isn’t that the truth…) anyway, there is a native driver (from ralink for the RT2571W/RT2671 chipset) and there’s the rt2x00 driver project and it’s also possible (and fairly easy) to install the Windows driver via ndiswrapper.

Live filesystem “capture” into a virtual disk image
ah… the joys of *nix utilities…. I’ve just successfully tested a “capture” of a live, running system into a virtual disk image. No, I don’t mean that I booted up with an imaging utility. I took a live, booted and logged in system and imaged the primary hard drive that it was living on, into a file on another machine. (Yeah, I know, there are probably a few people reading this and saying they’ve done that and most people that would need to do this already know how…. sorry I missed the memo.) Not too long ago, VMWare released a tool to do something like this (that tool is for windows…) This should work on any platform that supports dd and netcat (although I’m not sure if piping output from one program to another works with a dos command shell – maybe cygwin would be a good environment to accomplish this with.) Anyway… here are the details.

Vmware launches beta of real to virtual converter
Vmware has launched a tool (windows only it seems) aimed to convert a REAL running system into a virtual machine. (For use with VMWare’s virtualization products. The converter also can convert images from competing virtual machine “platforms”(?) (Microsoft Virtual PC, Microsoft Virtual Server, Symantec Backup Exec System Recovery (formerly LiveState Recovery) and Norton Ghost9 (or higher) to VMware virtual machine disk format.)

Exploits in wild for recent Apple vulnerabilities
If you’ve been delaying on updating with the recent Apple Mac OS X updates…. don’t, there are exploits in the wild now for at least one. It’s speculated that this code may have been in the wild before Apple released the security updates.

Multiple Apple updates as Mac goes to version 10.4.8
Apple is fixing 15 security flaws with the 10.4.8 version upgrade of Mac OS X. (There is a second update as well…. Security Update 2006-006). In typical fashion there are a bundle of issues in these updates. Several address remotely exploitable vulnerabilities.

Some days you really want to slap someone at Microsoft….
So, I was formatting a drive the other day. It’s an external hard drive that will need to be readable AND writable by both Mac and Windows XP machines. So, the only choice (without paying for MacDrive to read/write to HFS+) is really FAT32. The drive is in the 250GB-300GB ballpark. So, I reference the maximum filesystem size and see that FAT32 supports up to 2TB filesystems. No problem. I was doing this from the Windows XP machine that would be one of the drives “hosts” and after much scratching around created and attempted to format the FAT32 partition – a LONG verification process ensued 30 minutes – 1 hour. After which…. “volume size too big” eh? Well… the format tool under Windows XP/2000 is crippled…
