Speaking of utter nonsense!
Sometimes (not always) people fret too much. It's a Mac, after all, and not running Windows!
Sorry a pet hate of mine. 'Macs just work' is so not true. I've never had a PC as buggy and unreliable as my curent MacPro.
Mac mags/websites are full of articles 'How to fix/troubleshoot your Mac. Just like PC mags/websites. Apple kit has faults and Leopard is very buggy, heck one of the 'Geniuses' in my local Apple store said he never upgraded to a new Mac OS until service pack 4 or 5 as they were too unstable. Look at the tethering issues with 10.5.6. I've reverted back to 10.5.4 and get less freezes and OS crashes now.
The Beta Version of CS4 ran better/crashed less [if ever], on my aging PC laptop than the full release on my MacPro. It ran so well I forget to upgrade to release version and used it unti it expired months later.
LR 2.3 is defintely an improvement on 2.2 and updating LR on either OS is quite painless.
Converting a 1.4 cataogue to a 2.x cataloue was not however, did it on the mac and it corrupted. which loses you, all your virtual copies and if you don't autosave to XMP all your work
- If you haven't backed up.
