On my Mac (Mac Book Air, running OSX 10.13.5; Brain v. 9.0.264), The Brain is consuming CPU resources like crazy (64-69% in the background; 100%+ when app is in use). This is forcing my fan to run nearly constantly, and draining my battery fast.

Not good. Especially annoying because I am using The Brain more and more.

Something is amiss here. Please address!

Thanks.

Same issue with CPU consumption on Mac
Brain is in a separate desktop, not being touched nor visible for 10 minutes at least.
(even when not 'expanded' in a desktop, same issue)

Yet the CPU consumption never goes below 40%
When mild usage (opening some thoughts) it immediately peaks to > 100%

  • Mac OS 10.13.6
  • Brain 9.1.11

I used the brain for a long time, quitted a few years ago using it because of this high CPU consumption.
Wanted to give this great tool another try, but I am disappointed to see that this issue is not solved at all.

The brain cooks my macbook, instead of the other way around.

PLEASE fix this.

Kind regards

Changes were made that addressed this issue on macOS for many people in 9.1.7 (issue #2138).

If TB is in the background and is not syncing or otherwise busy doing a long running task (such importing or backing up), CPU usage should drop below 15% within 60 seconds.

Please provide more details as since we made the changes in 9.1.7, we have been unable to reproduce this issue.

When you say "Brain is in a separate desktop", do you mean in fullscreen mode on a separate virtual desktop?

If you run TB as a normal window on your main screen do you also see this problem?

How many tabs do you have open?

If you quit and restart TB, can you reproduce the problem immediately?

Thanks.
Regards,

I run Brain 10.0.50.0 and still, when working in a brain with really a lot of links, the fan is constantly working and CPU load is still as high as described. So this problem seems to have to do with hyper links, but man, that is what I use it for.
What I noticed is two things:
  1. when put the brain window in the background (minimize in the dock, CPU goes down, when you open it again up again
  2. when exiting the application and restarting it gets better until you start to add links or thoughts and using it heavily
I hope this helps the support team. Please keep investigating, the brain is the number one productivity tool for a lot of users and needs to be working normally!

Ah, I just noticed that we had a recent update that may help you.  Version 10.0.51 has an included fix that helps macOS users with CPU usage. This version is available on the Alpha Channel.

The Alpha channel contains frequent updates and provides access to the very latest versions. It is the recommended channel if you have an urgent need for a fix that is not yet available on the Stable channel and do not mind frequent updates.

To get on the Alpha channel:

Windows: Go to Options > Preferences > System > Updates, and select Alpha from the dropdown menu. Then go to Help > Check for Update, and install the update.

macOS: Go to TheBrain > Preferences > System > Updates and select Alpha from the dropdown menu. Then go to TheBrain > Check for Update, and install the update.

Thank you,
Matt

Same problem here!

I've been in contact with the support team—and they're currently investigating.

For context (of this thread), this is the request details I submitted:


"Hey guys and gals,

I'm having problems with TB spiking my CPU—and I'm not sure why!

When TB is idle, it's fine. When TB becomes the active window, the CPU immediately spikes—and it's not long until my Mac is overheating (and the fans are going crazy.

Any ideas why this would be happening, please?

Specs below:

- Macbook Pro 2018 [2.6 GHz Intel Core i7—32gb RAM]
- macOS 10.14.5 [latest version]
- TB v10.0.50 [latest version]

Look forward to hearing from you!"
