What is Wish I Were, please?


I Wish I Were is a control panel which allows one to set the mach 
identifier of one's Mac to something it isn't, on a temporary basis, such as 
during a software install.

A typical application would be to make one's PPC-upgraded Quadra appear like 
a 7100 in order to install a version of MacOS which is not officially 
supported on the PPC-upgraded Quadra, but is supported on the 7100, and which 
would indeed work on that Quadra (the PPC-upgraded Quadra and the 7100 both 
have 601 CPUs) if one could get beyond the install process.

So, the strategy is:

1) install the control panel,

2) change the mach to, say, that of a 7100,

3) perform the new MacOS install,

4) change the mach back,

5) boot the new MacOS.

In the specific case of Lind BU500, the mach would be changed from that of 
a PPC-equipped 500 to that of a 68K-equipped 500.

One source is:

http://macfixit.pair.com/library/tul/Wish.sit.hqx

Using this tool, one can install OS 8.5.1 on a 500 ... I've done that ... and 
some have claimed OS 9 can also be installed.

Re: Lind BU500 for PPC?

2001-09-02 Thread Mike Ferguson

The same question occurred to me, so I've been doing a bit of
research...now, I don't claim to fully understand this, but every model of
Mac has what's called a Gestalt ID, which appears to be something akin to
its fingerprint.  Thus when a piece of software is trying to work out the
best way to install itself, or needs to know what system its on, it checks
the Gestalt ID and adjusts itself accordingly.  Wish I Were lets you alter
the Gestalt ID so that you can fool the software into thinking that, say,
your PB540 is really a Quadra.  People seem to use this to install software
(typically OS software) on supposedly unsupported Macs (e.g. The 540 isn't
supposed to run OS8.5, even with a PPC upgrade, but Wish I Were can fool the
installer into running).

Unfortunately this utility doesn't seem to have been updated since about
'96, so the models you can pretend to be stop somewhere around the pre-G3
Powermacs.  If it's been updated (or something similar exists) I'd be very
interested to hear.

HTH

Thanks, again, Mike! This looks like a very cool utility, which I've
already downloaded, and will be looking for an update by anyone.

How about doing a quick swap of the 040 for the PPC for long enough to run
it?

That gave me an idea - I ran Wish I Were and set it as a stock 540c.  BU500
worked without a hitch.  Then, afterwards, I disabled Wish I Were and all is
well again.  ;-)

This technique can be used to install 8.5.1, say, on a Q950 which has been 
equipped with a PowerPC Upgrade Card, or on a PB540c which has been similarly 
equipped.

Apparently, some applications are checking the mach number at the very 
beginning, but these applications are not actually dependent upon the 
presence or absence of specific features.

It had not occurred to me to set the mach number to the machine's previous 
incarnation.

Good catch!

Lind BU500 for PPC?

2001-08-31 Thread Eric Schwarz

Lind's Battery Utilities 500 (Deluxe) was my favorite of the three battery
fixers (Apple IBR, EMMPathy, Lind BU500) since it was able to fix my 540c's
battery the best (It fixed all but one error, while the others left many
errors).  I've been using EMMPathy 2.1.  Now my battery is flaky, and I
can't run BU500, since I have a PPC card in my 540c.  Does anyone know of a
hack or newer version that will run on my 540c?

Thanks,
Eric
