You can swap caffeine for amphetamine it does the same job and was recently built from the ground up, so far I have had no issues migrating all of my tooling to Mojave
Damn! I didn’t even notice caffeine wasn’t working… thanks for the recommendation.
Edit: In hindsight, I now see that caffeine wasn’t working. When I updated BackBlaze per their instructions so it would run with Mojave the backups just weren’t making any progress. I realize now that my Mac was sleeping… replaced caffeine with amphetamine and BAM, 16GB backed up last night!
For the S1300, you can install the latest ScanSnap Manager for the ix500 (6.3 L70). It should work OK with the S1300 under Mojave, although it’s only 32-bit.
