First, the statement that "Paragon Rescue Kit for Mac supports all Intel-based Macs" is apparently contradicted by the User Manual which specifies:

"System Requirements

To use Paragon Rescue Kit for Mac OS X on your computer (it doesn’t matter what operating system is
installed), make sure that it meets the following minimum system requirements:

X86-compatible processor
[...]"

An X86 processor is a CORE 2 DUO, but I'm not certain what the "compatible" part means.

And second, the User Manual also mentions that

"Paragon Rescue Kit for Mac OS X provides support of major file systems presented on the market today:

[...]
Limited read/write access to Apple HFS+ partitions."

and since my (and, most likely, your) OS X installation is configured HFS+, why bother?

But I grabbed the Beta by the tail, anyhow:

1. I followed the CD/DVD (At 45Mb it requires only a CD.) burning instructions (which are located on Paragon's website, not in its User Manual) and was kinda skeptical about the ability of a 45Mb CD to boot my (Core 2 Duo) MacBook, but it showed up as a bootable option.

2. I was then kinda skeptical about the Paragon volume's being identified as "Windows," because I haven't got any such installation to boot into, but the manual says "it doesn’t matter what operating system is installed," and, after all, that's what backups are for, aren't they?

3. My deuced Mac(hina) booted pretty quickly to a screen that disappeared even more quickly, leaving me with a blank screen that gave no indication that anything was happening behind the scenes, nor did my HD sound like it was doing anything.

4. I gave it its head for a while, and then, when nothing had happened after a few minutes, I unsuccessfully tried to quit the app and was ultimately forced to power my Mac down.

5. I selected my HD from an Option-Boot screen: Apple screen --> Prohibitory sign kernel panic.

6. I tried to boot from my restore disc to run "Repair Disk:" Apple screen --> Prohibitory sign kernel panic.

7. I tried booting into Single-user Mode: Text hung at a message that some sort of USB device could not be found.

8. I tried to boot from my bootable (Verbose Mode) flash drive to run DiskWarrior: Text hung at a similar "missing USB device" message.

9. Sweating some, now, I tried (with little hope of success) booting from my backup HD with the expected lack of success: Apple screen --> Prohibitory sign kernel panic.

10. "Aaargh! What have I done to myself?" I agonized as I zapped PRAM with no joy.

11. Uh oh... Down to my last at-bat, I reset my SMU, and WHEW!!!

Until a response from the developer explains why I ran into the issues I've detailed I don't recommend this app to anybody!

And the fact that it is apparently not particularly useful with HFS+ installations is pretty damning, too.

Of lesser importance is the fact that Rescue Kit's VersionTracker page states that it "is designed to run on the following operating systems:
• Mac OS X 10.5 Intel
• Mac OS X 10.4 Intel
• Mac OS X 10.3.9
• Mac OS X 10.3
• Mac OS X 10.2
• Mac OS X 10.1
• Mac OS X 10.0,"

but OS X 10.0 - 10.3.9 were not capable of running on Intel Macs, the only ones it supports.

(Because of the possibility that my issues were self-inflicted I will not give this app the one-star review it seems to deserve [because I can't give it negative stars].)
