Dear Eustace Mendis:
WOW! Thanks !
First I really appreciate you finding this for me! Sorry for delay as I wanted to be certain about what I say here for others who may need the same HD with Firewire that I need and have only TIger....
.
Second, the Specs say it can use Mac OS from 8.6 upwards (of course that includes all OSX ones including my 10.4 Tiger).
But of course I'm a stupid guy.... Always got to check out what others say....
I found these reviews describing.. "a known problem". Maybe for others here in the Community this won't effect their ability to use the Mini Stacks on their Mac's but on my Mac G4 (... well first read the negative reviews below (there were postive ones too people who didin't have the problem) (and a guy who complained about the fan noise---- I don't mind the fan noise its only attached when I transfer data so its a short time---but during that short time) ----
Ok here it is:

2.0 out of 5 stars Causes Bluetooth / WiFi interference - beware!, December 7, 2012

------------------------------
Our brand new 2012 macMini became unusable once we stacked a miniStack underneath it - the bluetooth Magic Trackpad in particular was essentially unusable when the miniStack was powered on, and the WiFi signal became mostly unusable as well..
It seems that this is a known problem with the miniStack and USB3 - and this is discussed on the manufacturers website. They even now offer a "shielding kit" that they sell for $10 to "fix the problem". It installs internally inside the Mac Mini, requiring major surgery to install. But - it made no difference for me.
I tried switching from USB3 to Firewire 800, and that made some slight improvement.
But I can confirm that there is still terrible Bluetooth interference even after switching from USB3 to Firewire 800.
It still leaves the trackpad too unreliable for use - even at short range. Our Mini is under the desk, and the trackpad is on it. With the miniStack powered on (even if we are not transferring data!) the Bluetooth starts to drop out.
Turning off the miniStack immediately solves the problem, and there are no issues with any of our other external drives - so I can only conclude that the issue must be in the design of the miniStack. Our SeaGate GoFlex USB3 drive has not had any of the same interference issues.
I'm not sure what other things I might try other than relocating the miniStack away from being directly underneath the Mac Mini - which kind of defeats the whole "stack" point of the product.
This has been incredibly frustrating, and I feel I have no choice but to return this. *grrr*

I bought this drive so I could stack it on top of my 2012 Mac Mini. The Apple Wireless Keyboard and the Apple Wireless Magic Trackpad are unusable when the MiniStack and the Mac Mini are stacked together. Read the discussion on OWC's blog on their site [...]. OWC will sell you a kit so you can open your Mac Mini and apply some shielding. Watch that video on their blog to decide if you are comfortable with taking your new Mac Mini apart. Oddly, other USB3 drives work fine with the Mac Mini according to the discussion on the blog. I have many drives from OWC and all have been great. This MiniStack situation is unusual for them. The fan is quiet, and it looks great. Asking the consumer to take a new MacMini apart is NOT a solution.

I'm back...(after posting the reviews)....
I know these 2 are profesional reviewers and I'm still searching the net to find the source of the technical problem that causes loss of blue tooth connectiveivity...
The shielding kit they describe is for the Mac Mini, not my larger G4 where I think the Bluetooth antenna is actually encircling the display screen---anyway after 10 years I'm the last person to go and play around inside my G4 laptop and no one else will touch it either as its too old (Apple Store refused 4 years ago for a minor repair saying then it was already "out of warranty"...
I use two items that are unusual with most laptop users... My laptop is treated as a "desktop" really never travels (especially since airports tend to xrays it!)
I use a major large ergonomic keyboard and mouse combination when using the "laptop"
I type a lot, burnt through two of these boards in 10 years and the one I got looks terrible... But it keeps the G4 silver keyboard and track pad areas pristine new!
The problem is both devices are connected to the USB port with a mini-bluetooth transmitter, and use Blue tooth connectivity to provide true wireless keyboard (place it on top of books I"m typing and copying etc from)=easy! and mouse can be used anywhere on the desk!
But if I try to use this to move files between the computer and new mini stacks and trying to label new files and directories, etc I'm useless, without those expanded keyboard and mouse helping me.
(Of course I can use the small keyboard on the G4 and trackpad, but I've not done that for years, when someone at work says to me; can you do this on my laptop, etc. I always carry a bluetrooth portable mouse that plugs into their unit and instantly I can whip right through things without ever having to learn how to maneuver on that tiny touch pad (and a roll up keyboard provides me with 188 keys too if they have a second USB port free).
I also use the Blue tooth system on my phone to transfer photos when someone asks me for a few recent photos I just did and I don't want to bother removing the whole GB Chip to mass transfer items and guess what the phone uses to send to the laptop? Bluetooth!
So I'm not complaining so much as giving those who read this thread some food for thought if they use the amount of bluetooth items so close to the laptop and the new drive from "newertech"...
I'm going to have to find another distributer on the newertech pages as I referred to the problems that people had ordering from OTC "Other World Computing" and if the new drive should have any problmes I"m devastated trying to deal with OTC according to their complaint list on the reviewers pages...
Of course I'm remaining optimisitic at your discovery for me....
Its not something I can spend time experimenting with as one of the two G Drives is making noises and is 4 GB free other one is the 10 GB free I unfortunately have purchased "two" backups for the main computer and photos are also backed up twice so I need to order two new drives to retain the level of safety in backups for the G-Drives that have to be replaced.
I instantly liked the idea of being able to "stack" them and hopefully OTC might send perfect units that don't have to be returned, but I don't really want to take that chance with my irreplaceable photos..
Please don't take my objections against you personally Eustace, as I really appreciate again your find!
If you have any other comments after reading all this (or anyone else out there), please don't hesitate to add them in here as I know there are others out there will G3, G4 and G5's still working!
Thanks again!
