Excellent link! terrychay.com/article/macports-vs-homebrew.shtml Thank you!

comment How do I install GCC via Homebrew?
How so? To be honest, I dislike Homebrew mostly just because it lacks (a) package descriptions and (b) math packages. Overall MacPorts has maybe six times as many packages as Homebrew, but yeah it's the obscure packages that're missing. I'm happy with MacPorts overall, although obviously I wish they'd integrate with language package managers like CPAN, CTAN, Caball, etc.

Why use Homebrew? MacPorts is good at managing multiple versions of compilers. And MacPorts can do anything that Homebrew can do.

comment Are Macs vulnerable to the Bash shellshock bug?
Ain't such a big deal but you guys are repeatedly saying things that're technically wrong. You cannot be 100% sure without doing more legwork. Apple might've done that legwork for their servers that remain up with firewall enabled before issuing their statement, but actually I doubt they did even that much. It's probably fine but one should still bust Apple's chops for being so painfully slow to fix their bash itself.

Yes strings .. | grep SHELL is far more useful than bash, but not absolute. Imho nm -a ... | grep system is the most important, and exec helps too, but that's only for vanilla BSD, Linux, etc. software Apple's libraries offer different routines. Just use the Cocoa way for example : stackoverflow.com/questions/412562/…

Not quite. One must review the symbols called by the library that otool -L /usr/libexec/bootpd reports that contains an exec call. And the strings command is pointless since environment variables determine the shell called. I'm impressed however that no liked library calls system.

heh. SE edit boxes don't like the Mac's spelling corrector, always creates premature comments. Sorry about that. Anyways..

I already mentioned that recompiling bash is overkill myself. The correct response for ordinary desktop uses is to turn on firewall and turn off sharing services OR to accept that they're trusting the firewall provided by their router. That's what my comment says. You single out a probably usually non-vulnerable server, ssh, and ignores that an awful lot of people doing rudimentary local web server with unknown active scripting.

In fact, your answer is totally wrong!!! Ordinary ssh usage isn't vulnerable since you're already opening a shell, only ssh's restricted login command is vulnerable. Almost no Linux users even know about that, so like no Mac users do.

As I said below, ALL servers should be assumed to call bash unless proven otherwise. And Mac OS X is full of privilege escalation exploits once you reach a shell.

Apache modules, CGI scripts, etc. commonly call bash. Very effective hack right here : twitter.com/JZdziarski/status/515135854436962304 And even if your Apache configuration does not call bash under normal operation, no telling what an attacker can convince it to do.

How do you know that? Initial advisory was a vulnerable DHCP client. And many articles speculate that Mac OS X and/or iOS DHCP clients might be vulnerable. All servers should be assumed to be vulnerable unless proven otherwise.

There are likely privilege escalation risks from a guest account too. Who cares though? Any Mac OS X machines is extremely vulnerable once users get access, especially local users. It's server daemons that should scare you, not just sshd though, all server daemons.

-1 Very wrong. There are many tools that use bash : Installation scripts usually use bash, creating privilege escalation risks. All servers should be assumed to use bash unless you know otherwise, not just sshd. In particular, apache could create a remote vulnerability using bash. etc.

comment Are my frequent Safari beach balls caused by my extensions?
Yes, I may need to try disabling all extensions, the one at a time hasn't yielded anything useful yet. It's also simply possible that Safari has grown long in the tooth and I shold give Chrome another try, definitely Chrome has a better JavaScript engine.

Immediately after posting this I deactivated Ghostery, not yet positive matters improved, but it's looking up. It's tricky because it's sensitive to specific open tabs as well.
