notes for Mini vMac

There are two issues in recent versions of OS X that cause
|
|
problems for Mini vMac.
|
|
</p>
|
|
|
|
<blockquote>
|
|
<p>
|
|
Quick Fix : run “xattr -cr <Path to Mini vMac>” in
|
|
the terminal.
|
|
</p>
|
|
|
|
<p>
|
|
(step by step instructions <a href="osx_note.html#step">below</a>)
|
|
</p>
|
|
</blockquote>
|
|
|
|

|
Further explanation:
|
|
</p>
|
|
|
|
<p>
|
|
One issue is caused by Path Randomization, added in macOS Sierra (10.12).
|
|
If an application that Apple thinks is trustworthy is bundled
|
|
together with malicious library code in the same folder, the
|
|
malicious code may be run by the application. The silly way that Apple
|
|
has chosen to prevent this is to in effect move the application
|
|
somewhere else before running it, so it can’t find the library code.
|
|
It can’t find anything else in the application’s folder either, which
|
|
is a problem for Mini vMac, which looks for things in its folder,
|
|
such as the ROM image file. One work around is to put the image
|
|
in one of the other places that Mini vMac looks, as described
|
|
in the
|
|
<a href="hardware.html#rom">ROM section</a>
|
|
of the Emulated Hardware Reference. Another option is to tell macOS
|
|
not to do Path Randomization for Mini vMac, using the xattr command,
|
|
as described in more detail below.
|
|
</p>
|
|
|
|
<p>
|
|
The other issue is caused by Gatekeeper, added in OS X Mountain Lion
|
|
(10.8). By default, the operating system will refuse to run applications
|
|
downloaded from the internet, unless Apple considers it trustworthy
|
|
(because it is digitally signed by a developer registered with Apple).
|
|
Gatekeeper is in some ways a good idea, but some people consider it as
|
|
one step along the way to making OS X like iOS, where no software
|
|
can be installed without Apple's permission, and emulators are
|
|
forbidden, including Mini vMac. So I decline to participate, and Mini
|
|
vMac is not signed with an Apple Developer ID.
|
|
One way to override Gatekeeper, giving an application permission to run,
|
|
is to hold down the control key and click on its icon (or right click)
|
|
to get a contextual menu, then choose the Open item, and in the warning
|
|
dialog that comes up click on the Open button. (This only needs to
|
|
be done the first time Mini vMac is run.) Another option is
|
|
to use the xattr command.
|
|
</p>
|
|
|
|
<p>
|
|
<a name="step"> Using xattr, step by step: </a>
|
|
</p>
|
|
|
|
<p>
|
|
* From the Finder, choose the “Utilities” from the
|
|
“Go” menu.
|
|
</p>
|
|
|
|
<p>
|
|
* Find the “Terminal” application
|
|
(in the “Utilities” folder just opened), and launch it.
|
|
</p>
|
|
|
|
<p>
|
|
* Type “xattr -cr ” (not including the quotes, but
|
|
including the trailing space), into the Terminal window that has
|
|
just opened.
|
|
</p>
|
|
|
|
<p>
|
|
* Drag the icon of the Mini vMac application into the terminal window.
|
|
(This should paste in the path string). The result should look
|
|
something like:
|
|
</p>
|
|
|
|
<blockquote>
|
|
<pre>
|
|
xattr -cr /Volumes/rd/Mini\ vMac.app
|
|
</pre>
|
|
</blockquote>
|
|
|
|
<p>
|
|
* Press the return key to execute the command. (This clears
|
|
all extended attributes of all files in the application
|
|
bundle.)
|
|
</p>
|
|
|
|
<p>
|
|
* You should now be able to launch Mini vMac without interference
|
|
from Gatekeeper and Path Randomization.
|
|
</p>
|
|
|
|
<p>
|
|
<b>warning</b>: You should only do this for applications that
|
|
you have reason to trust. Please only download Mini vMac
|
|
from pages on “www.gryphel.com”. It would also
|
|
be to good to check the md5 checksum and the signature.
