Without prior indication, when starting iTunes on OSX 10.6 .4 I suddenly received the error dialog stating “This copy of iTunes has expired.” And Software Update states that all of the software is up to date.

The simple resolution is that a beta version of iTunes 9.2 that I installed did expire (so much for reading the fine print) and a re-installation of iTunes is required. iTunes can be downloaded on the apple site as a dmg file. When opened and the volume is mounted, run the iTunes.mpkg installer to restore the computer to a happy equilibrium. Fortunately, the beta version of iTunes does not need to be removed prior to installation.

The disk on my MacBook Pro was going bad – S.M.A.R.T. reported imminent failure. I had Apple swap it out for a new one and I restored the new disk with my backup from Time Machine. Unfortunately, with the archaic way Adobe licenses its products, it was the only software I had purchased that did not work after the restore. After two hours online with Adobe support, I was not able to get much further.

After much trial and error, I determined the only way to get the software activated was to fully remove Photoshop CS2 and reinstall. I followed this technote from Adobe to manually uninstall Photoshop CS2, but it was incomplete. I had to remove a license file and only then could it activate successfully. In addition to the files Adobe asks you to remove, the real magic file that needs removal is /Library/Preferences/Adobe Systems/Product licenses_120/B2B86000.dat. After removing that, along with all the others, I was able to get CS2 installed on my machine and successfully activated.

It appears as though the sound is configured correctly on the host machines, but no sound comes from the client when a sound is made. This works when using a Windows Remote Desktop Client but not on the Mac.  It turns out that the audio redirection feature of RDC does not work; you will need a hotfix to resolve the issue. After installing the hotfix and rebooting the server computer, sound now plays on the client!

To obtain the hotfix, navigate to http://support.microsoft.com/kb/973062 and click on View and request hotfix downloads. Click through the license agreement and select the hotfix that corresponds to your operating system. Fill out your email address and submit. Soon you will receive a zipped install executable that will install the fix for this issue. Upon rebooting and reconnecting to the host machine, you will hear sound!

My computer was failing frequently so I had it serviced through AppleCare (actually the “Depot” for much less than Apple) and they replaced the logic board. Turns out that iTunes authorizations are tied to the logic board. Without the old motherboard, it is impossible to de-authorize the account for the computer and thus an additional device (the computer with the new logic board) must be authorized (of the five allowed). Of course, I already had five devices authorized so I had to de-authorize all and re-authorize my active devices.

Moral of the story is if you send your mac in for a logic board replacement, make sure to de-authorize the computer prior to service; this will allow you to authorize the computer upon receipt and not consume one of the five authorizations for the phantom computer.

After installing Xcode 3.2.1 and the Aperture 2.1 SDK on Snow Leopard, I was unable to compile a simple (empty) Aperture plug-in due to a missing file, PROAPIAccessing.h. I was finally able to get it to compile by downloading and installing the FxPlug SDK Version 1.2.5 – this includes PROAPIAccessing.h.
