Pro tools won't launch

There's a possible workaround given at this [Kingsley page|http://mckingsley.com/2008/12/pro-tools-731-not-working-with-the-latest-ap ple-security-update].

that workaround seems to work for me. good find my friend. i hope apple notices and delivers a real fix.

I was having the same problem this morning. I was planning to do some keyboard overdubs at a friend's house, and wasted 2 hours trying to get Pro Tools 7.3 to launch on my Macbook (Tiger, 10.4.11). I uninstalled and reinstalled Pro Tools, then did every single thing trouble shooting tip I could find on the net, twice! Somehow, Pro Tools started to work again. I think launching Pro Tools through Terminal helped, and also that 'prebinding' thing. Not sure exactly what it made it work again, but my advice would be to just do everything listed on the trouble shooting page.

Strange...
I did some maintenance stuff using Onyx, and my Pro Tools stopped working again. So I reinstalled everything again, still didn't get it to work. Then I created a different account, and accessed Pro Tools under that account. Pro Tools miraculously started working again.
So my advice to all you PT users out there who are having problems, create a new account, log into that instead and see if Pro Tools decides to actually launch.

There is a Digidesign support forum thread on this subject at

For those with ProTools 7.3.1, there is a new (1/13/09) post there (second page) from their tech support:

For anyone experiencing this issue, we now have a beta version of the installers (HD, LE, MP) that should work. Please keep in mind these are beta, so back up your system before installing!

You'll need the DigiDelivery client software to download:

And then use this link to download the installers (single package at the moment, 382MB):

This is only for those on 7.3.1 - anyone on 7.1.1 will need to do the archive and reinstall.

to get the actual links.

you should create a new admin account and then run PT from that account. That worked for me ... after some hours of trouble shooting........

After I did all the hoopla with the troubleshooting crap for two days, okay 14 hours, I still had no luck.
For whatever reason, this was successful. Hold on to your seat.
Step 1. Log out as startup User and Log in under Guest user
Step 2. Don't do anything. Yep, just look at screen aimlessly for a few seconds.
Step 3. Log in just like you were before you started doing what your doing
Step 4. Launch the now functional Pro Tools
Step 5. Say a few expletives and happy making
