Severe Performance Issues - GoldenCheetah/GoldenCheetah GitHub Wiki

Some users are experiencing very poor performance after upgrading to Mojave (MacOS 10.14) s.t.:

• Launch takes about 30-45 secs
• Importing a new activity, the file picker window takes maybe 20 secs to appear
• Switching to the Trends view is the worse case, it takes almost 5 mins to switch view and meanwhile my Macbook is virtually unusable due to the CPU usage.

If you find GoldenCheetah on System Preferences and inside "Security & Privacy" then under the "Accessibility" as below: You can uncheck the accompanying checkbox or remove the entry using (-) to solve this issue.
