[comp.sys.mac.programmer] System 7 questions

gerhard@cs.arizona.edu (Gerhard Mehldau) (06/22/91)

I've just upgraded my IIfx from System 6.0.7 to System 7,
and now have several questions relating to the new system.

(1)  I seem to remember that the Disinfectant INIT is
     supposed to load last.  Is this true, and, if so,
     can I just move it from the Extensions Folder to
     the Control Panels Folder without any ill effects?

(2)  I have been using the MM INIT, which supposedly
     fixes a bug in the IIfx ROM.  Is the INIT still
     necessary with System 7, or has the system soft-
     ware been fixed?

(3)  Is there a way to structure the items appearing
     on the Apple menu?  I would like to be able to
     specify the order in which things appear on the
     menu (without having to prepend weird symbols to
     file names to fool the alphabetic sort), and I
     would like to add separator lines in arbitrary
     places.  I would prefer a "built-in" solution,
     but if there is an INIT or CDEV that does this,
     that would be fine, too.

Thanks for any help.

- Gerhard

Can we put this in the FAQ's, please?

This is the honest truth:

The version of MMInit that was illicitly leaked to the world has bugs
in it, that cause crashes.

An improved version of the fix is included in System 7. It's been
tested and shouldn't cause crashes.

If the Init is used with System 7, it overrules the improved version,
and causes those same problems, so don't use the MMInit with System 7.

The problem with the memory manager in the first place is very rare,
such that even you power users might never run into it. The MMInit
does NOT provide a noticeable speed improvement in day-to-day use.

The best plan:

If you think you need the improved memory manager, use System 7, NOT
the MMInit.

You'll get all the improvements and (hopefully) none of the bugs.
