// UPDATE May 23, 2022: BetterSnapTool 1.9.7 is now available on the Mac App Store. The fix mentioned below is not necessary anymore.
Can you try running this terminal command while BetterSnapTool is quit?
defaults write com.hegenberg.BetterSnapTool BSTEnableEnhancementCheck YES
Grammarly and 1Password 8 seem to enable the accessibility enhancement mode in Google Chrome (I think this is bad because it means Chrome will use much more CPU), and this causes issues. With this command BetterSnapTool will try to disable this feature before each snap (and enable it again if it was set before)
If you are not familiar with the Terminal, here some more detailed explanation on how to execute the command:
1.) Open the “Terminal” app (this is located in your Applications folder in the sub-folder “Utilities”, but you will be able to open it using Apple’s Spotlight.)
2.) Quit BetterSnapTool (click the menubar icon on the top right, then select the quit option)
3.) Copy this command into the Terminal app, then hit the enter/return key:
defaults write com.hegenberg.BetterSnapTool BSTEnableEnhancementCheck YES
4.) You can now launch BetterSnapTool again and the issue will be fixed.
