Willm60 Posted July 24, 2019 Posted July 24, 2019 Hi, I recently purchased Affinity Photo after checking on the website that it was compatible with my MacBook mid 2012 with 16Gb RAM and 500Gb SSD. All worked well with 1.6, but since the recent update to 1.7.1 my MacBook gets extremely hot (too hot to touch) and the fans run very loud. Activity Monitor shows that, at times, when working with RAW files, selecting or altering exposure/saturation etc in Develop Persona, CPU usage is over 200%. I note that other users reported overheating in 2017, but there seem to be no recent posts, so I'm assuming no-one else now has this problem. Are there any alterations to settings I can make to remedy this, or is it ok for my laptop to run so hot? I'm new to these forums so please accept my apologies if I've posted this in the wrong place. Any help much appreciated because at the moment I daren't use AP in case I damage my laptop. Thanks. Quote
Staff Lee D Posted July 25, 2019 Staff Posted July 25, 2019 I'd recommend downloading and installing the latest beta of Affinity Photo using this link. This beta will install alongside your existing version and contains fixes and improvements over the current version and will hopefully help with the performance of the app. Quote
Willm60 Posted July 25, 2019 Author Posted July 25, 2019 Thanks Lee, I've given the beta quick trial and it does seem better - haven't had chance to run it for a long time with lots of images yet, but so far so good. Thanks. Quote
thomaso Posted July 25, 2019 Posted July 25, 2019 15 hours ago, Willm60 said: CPU usage is over 200%. As far I know this value means max. 100% for every single CPU kernel. (theorethically an app process on a mac with 8 kernels can use up to 800 %). Though you have 16 GB of RAM the issue could be a lack of RAM causing the occurrence, for instance if many tasks are running at one time, even if in background, which might need to get compressed and/or written to the Swap area. So you could watch the RAM section in Activity Monitor, to see if it switches while working from green to yellow or red at some time. And if then close other apps or open images to free RAM.

Willm60 Posted July 25, 2019 Author Posted July 25, 2019 Thanks. I'll check out the ram usage and background tasks, although my Mac is only an i5 dual core, so 200% + still seems high for 2 cores. Quote
