Hello all!
Firstly does it support hard drive/multi-disk out of the box, or does it need any updates done. And if so how do you go about updating? In the early days I noticed posts about having to hook up your Minimig to a PC to update certain elements and I'm not sure if I'd be able to do these on my iMac.
I don't know about updating the PIC under OSX but you can do it with an Amiga (68k, OS4 or MorphOS) or AROS as well as under windows see tinybld PIC uploader

As the minimig does not have support for multiple mice or connecting more than 2 joysticks I don't thing Multiplayer Hired Guns will work.
I will also second the advice to go for the 4MB version of the minimig or you will quickly fine yourself returning it and paying AmigaKit to upgrade it if you want to use software and games from harddisk.
If you want to run AROS-68k on it you also need the 4MB version, but even then you will only have 2.5MB of free ram after soft-kicking the AROS rom as the commodore rom uses 512K and the AROS-m68k ROM uses a further 1MB, before you even get past the AROS boot screen.
