AE rendering suddenly so slow

I've been having issues with Finder (Mac) and Ae slowing down when rendering TIFF sequences. Say... the estimated time to completion is 20 min, but I come back in 10 and the ETC is now 2 hours. In regards to Finder, files don't show. I have to restart Finder to find the image sequences, and even mounted drives. So... the problem was solved for me after disabling most of the iCloud features on Mac. That solved the problem immediately. After Effects was using only 30% of the ram, so definitely not a ram issue. Hope this helps!

So to be clear, did you still have this issue with a specific sequence?

Hello OussK,

Actually, that's not true in my case, on my iMac. Right now, everything is so smooth, I'm working in AE, Lightroom, LRTimelapse, Safari and Mail, and have no problem with rendering.

when you open many application on your iMac your RAM come full, so AE start goes slow and slow because their are no enough RAM, so when you want to render it's better to close all the application running in the background, also you can install some memory cleaner app to free your ram before render.

Dear Vidya,

Thank you for the concern and answer. Strange, yesterday, after rendering first sequence, with time trouble, every single sequence after that rendered under 3 minutes. I didn't even restart my iMac.

Frankly, I have no clue what's going on with AE. Other programs work fantastic.

Thank you.

Hi skipper_ri,

Sorry for the trouble. Have you updated the OS or any other related program/third party plugins?

Try fixing the permissions & clear the old media cache and check if it fixes the issue.
