Unfortunately, DEVONthink PE 1.5.3 (and only exactly this release) doesn’t run on Mac OS X 10.1.x. We’re close to releasing a new version, though, that will again run perfectly on older Mac OS X systems.
Thank you so much for continuing to support the older versions of OS X, it’s much appreciated. I know several people who just can’t get Jaguar or better to run on our hardware (the endless litany of attempted fixes shall not be spoken here). And until the economy improves, it looks like we’re stuck w/ our aging and/or defective hardware (the other guys having trouble have newer machines than mine, some recently top’o’the line. Go figure…).
Anyway, thanks again for the prompt reply. I’ll download ASAP, and look forward to the new release.
